Discussion Of Climate Change

Healthy is probably not the first adjective that climate change skeptics would use about their position. At least that’s my conclusion given the pariah status conferred on anyone who resists the conventional wisdom that climate change is both bad and caused by human activity. Skeptics have been chastised, vilified, even threatened. And some have retaliated with their own aggressive defense.

Climate change presents a serious challenge to the UK and to the international community. Recent Climate Change Conferences in Montreal and the G8 and the Gleneagles Summit have attempted to co-ordinate the international response to climate change.

Hot Topic: Climate Change

The problem is that to get people fired up about a long-term, diffuse and tricky to resolve problem like climate change, some fervor is required. It is a problem where acute pain will creep up on us, many times undetected. And even when effects are acute they’re difficult to attribute. After all they could have happened by chance anyway.

Most climate change is actually slow and slow change is hard to prove. It is even more difficult to spend public money on or, worse still, put in place policies that might hamper economic growth, just to slow further an already slow change.

So the solution was to speed it all up. Add some intensity and make the whole thing immediate. Al Gore made Inconvenient Truth in this style. Create some buzz using fear.

Only this is difficult to maintain. Momentum is easily lost when the basis of the argument is emotion and not unequivocal facts. Most of the time we need to be in a position to see it to believe it. This is why there’s still a million people in the world who end each day hungry. If we saw poverty with our own eyes we would soon do something about it.

Climate change isn’t visible. It is a gradual shift in weather patterns, perhaps a subtle frequency change in extreme events. It manifests as earlier onset of spring, a shorter than usual rainy season or a few more tornados. But all of these could happen by chance.

Whether or not last week’s tornadoes were caused by climate change, extreme weather is on the increase. ‘

Skeptics become more than a nuisance in these circumstances. Inevitably they want evidence to be convinced of the phenomenon. This is what skepticism is, an open-mind until there is enough evidence for a decision either way. Only in the climate change debate, just asking for more evidence is equivalent to treason.

Except that climate change skeptics are vital even if global warming is real and proves to be caused by human actions.

If we must spend money to reduce emissions, slow growth in the utilization of fossil fuel around the world [a huge call for all those countries with emerging economies ] and to take measures to adapt to climate change then we need to find out these are genuine priority tasks.

Climate change negotiators have been working on an international deal to slow global warming, including a UN proposal called Reducing Emissions from Deforestation and Degradation (REDD).

Climate change action needs to be more important than direct spending on poverty reduction, food security, health care, conflict resolution, education, and a series of local issues.

Just today I heard a caller on a radio talk show advocate that $4 million in taxpayer finds should be spent on a public swimming pool rather than more car parking space at the train station. For him the pool gave a much better public outcome. He probably would have some friends among the climate change skeptics and a few ‘what are you thinking’ from the warmers.

Skeptics force us to be so that any action is the correct call. It is a weak position to just ignore or attack a naysayer.

Given that I have been advocating for the courage of skepticism I thought I should take my own little questionnaire to out myself on this issue.

Are you a climate change denier? No. I believe that climate change is real. Climate has always changed and always will.

Do you believe that humans are at the root of what many see as global warming? Probably, because we have changed enough of how the natural world works. We have released carbon from vegetation and soils, and burnt enough fossil fuels to have an impact on atmospheric dynamics.

Scientists have sternly put forth their view on the most important natural cause of climate change as human extension of the greenhouse effect and global warming. This effect is a type of warming that is caused when the earth’s atmosphere entraps the heat that is meant to be radiated from the ground in direction of space. Gases such as carbon dioxide, methane, nitric oxide, and water vapor in the air act as a glass on a greenhouse that allow the sunlight to cross, however, blocking the heat from dodging.

Is human activity the only driver of a changing climate? Definitely not and it’s easily trumped by the bigger cosmic cycles. Human activity may be a climate nuisance. However, we’re not all powerful.

Can humans ‘fix’ climate change? No, we cannot ‘fix’ something that is not broken. That said we should reduce our impacts but it isn’t in our powers to end the climate changing however much we might like to think we can. Instead we should be investing our smarts and resources into managing the impact of climate change on our production systems.

So are you a climate change skeptic? Yes I am, because I have always been cautious and needy for evidence. ‘ Innocent till proved guilty’ is a much more powerful way to gather the truth than to just presume guilt.

I am even reasonably convinced that human activity of the last 200 years [before then there were too few of us to really have any impact ] is enough to be a driver of further change.

These realities mean that we will need skeptics to help us make sure that it is useful to all the effort to get awkward policies through our national and international political processes or, to put it more simply, to keep everyone honest.

Climate Change Debunked

Climate Change has actually become a bit of a buzzword in today’s media. In the 1980’s and 1990’s, we frequently heard scientists and press reporters describe ‘Global Warming’, suggesting that our planet was getting warmer. That seems fairly evident, and is a precise description of exactly what appears to be happening. Warming may only be a catalyst for a change in the overall climate of our planet. Thus, the term ‘Climate Change’ was born. As opposed to a sweltering sauna of a planet, there may stand out shifts and alterations in different climates around the globe.

Climate change is a frightening thought. To think that our planet could be in the beginnings of a radical shift in weather patterns that may be permanent is frightening. The secret to understanding and preparing for any event is to get an idea of exactly what is the potential cause.

Climate Change: The sustained modifications in the regional weather elements over a long period. Climate change not only describes temperature however also incorporates changes in the wind patterns, humidity, rain and serious weather occasions.

Some Climate Change Ideas

The scientific community tends to concentrate on greenhouse gases as the driving force in climate change. An insufficient list of greenhouse gases would be: water vapor, methane gas, nitrous oxide and co2. The 2 getting one of the most press are methane gas and co2. Methane is discovered naturally as it is excreted from stock and their waste, as well as existing in large deposits in permafrost and other sources. Co2 is by and large guy made, being discharged from cars, boats, engines etc. Nearly all energy expenditure that is dependent on the burning of f=’/ Fos sil Fuels’) fossil fuels such as coal and oil, results in the release of carbon dioxide and other greenhouse gases.

In the same vein.

As atmospheric levels of greenhouse gases remain to rise, they function to trap the heat and energy originating from the sun. As an essential side note, there is a school of thought that solar variations are playing a large part in climate change on earth. In reality, it is most likely that there is at least some combination of solar variations and greenhouse gases. The essential element though, is that greenhouse gas exhausts are a concern we have at least some control over. We have no control over what the sun does, however we have a selection as to exactly what vehicle we drive, exactly how typically and far we drive it and so on

Continuing On….

Now that we have a passing understanding of what the 2 significant greenhouse gases are, and what some potential sources for them are, we can move into potential results of climate change.

The prospects of a warmer climate noise appealing if you are living in a cold environment. Whatever benefits could be obtained from a somewhat warmer climate, would likely be balanced out. Increasing seas due to glacial melting, disruptions to sea currents, potential long term dry spells and the influence on wildlife, wilderness, and human populaces are all real possibilities as both brief and long term results of climate change. Fortunate is that we can be prepared, and if sufficient individuals begin to take action, consisting of governments, we can ideally reduce if not stop climate change as we currently understand it.

It is a tall order, however the steps needed to start countering climate change start with the individual. Often, individuals planning to their governments to do something about it. Nevertheless, governments tend to have a short-sighted outlook considering they have to answer to the populace for their decisions. Everyone has to be aware of their ecological and environmental ‘footprint’ that they are leaving. It could not be too late to have an impact and leave a much better world to the next generation.

Examining Climate Change

Point out climate change and many people will inform you it has a lot to do with the weather condition however in actuality climate change is more. From carbon offsetting, to managing of waste to the sustainability of the world, climate change has a fantastic influence on each person. Those who take the time to understand real climate change and some of the influences that cause such change are commonly stunned to find just how fantastic of an impact exists from the climate, exactly what impact that climate can have on each person and the actions that can be taken in a group effort to ensure a positive climate change for the future.

Fact: The climate is changing. It is actually changing for millions of years and will remain to change.

The climate or environment is the environment surrounding you wherever you are, whether it is your office or home or anywhere else. Worldwide climate change is of the utmost concern and has come around as an outcome of things like energy consumption, the manufacturing of carbon, the increasing variety of automobiles on the road and so on and we have to remain to advertise renewable energy schemes and public policy lobbying for these efforts if we are to reverse some of the damage currently done. As you might understand, the more outlets that are powered by renewable resource, the even more energy consumption can remain to be cut. Minimizing gas and electricity consumption and making use of renewable energy rather can just be excellent information about the natural surroundings.

Some Climate Change Ideas

Renewable energy is energy that originates from endless sources. This is in contrast to coal and petroleum, which are nonrenewable fuel sources that exist in a limited quantity and are for that reason non-renewable. Examples of renewable resource (in some cases called alternative energy) are wind, geothermal, and solar power, as well as hydropower and biofuels. As it pertains to climate change, renewable resource is not just crucial since we won’t run out, however, mostly because it does not produce carbon dioxide.

Carbon offsetting is an effort aimed to lower the amount of carbon being left to toxin the earth and includes things like planting trees which take in carbon. This is just suitable to carbon emissions caused by the planes, however, automobiles and other sorts of equipment likewise halve carbon emissions that can affect and change your state of mind if you are consistently exposed to them.

For this reason, modifications made to decrease carbon emissions are progressively important and are becoming the focus of many carbon offsetting initiatives.

Another location in which climate change can be adverse is by the use of hazardous fuels that are removed from sources such as oil. These hazardous fuels can cause significant harm to the climate if left uncontrolled. A sound understanding of how climate change occurs paves the way to being an informed energy user as well as somebody who makes sound selections that assist to promote positive rather than unfavorable climate change. There are numerous climate change charities and companies working full-time on efforts to produce long lasting and positive change through these initiatives so there are always resources and occasions for those who want to, to get involved in.

Learn all the realities about climate change online and see how you can get involved in everything from reducing your carbon footprint to helping to eliminate worldwide poverty.

The Latest On Climate Change

The general state of the Earth’s environment is largely impacted by the amount of heat is saved in the atmosphere. The causes of environmental change is not just due to manufacturing pollution of the environment, but also since the modifications in the amount of greenhouse gases in the air which have actually taken place naturally throughout the history of the Earth. Then there are also various other procedures that alter the environment of the earth extremely, really slowly over millions of years. This is why the research task like these are crucial for us to understand these natural processes.

It is true that climate modification has actually naturally occurred over a duration due to elements like solar activity, dust in the environment and volcanic activity. Nonetheless, in the current years, human factors have affected climate modification substantially. To produce a demarcation in between the two terms, the United Nations Framework Convention on Climate Changes (UNFCCC) utilizes the term ‘environment modification’ to indicate the modifications in the composition of the environment and the resultant climate variations due to human activity, while the term ‘environment irregularity’ refers to the natural environment modifications.

Climate Change Conundrum

Much has actually been said about environmental change over the last few years and with remarkable findings such as this ice core, it reveals yet once again the number of tricks the ice holds, for our world and beyond.

Impact of Climate Change on Crop Production

imagesCrops have always been sensitive to climate change. Even a single season of not enough or too much rainfall, a hot spell or cold snap at the wrong time, extremities of weather such as floods and storms; all have a debilitating effect on crop yields and livestock production.

That was one side of the picture. The other of the picture is totally opposite. One recent research of Stanford University reports 5% increase in global production of maize and wheat since 1980, as a result of to climatic changes. Raised carbon dioxide concentrations – the main cause of climate change – could increase production of some crops, such as rice, soybean and wheat.

The future course of global food production will depend on how well societies can adapt to such climatic changes. According to IPCC, the agriculture of poorer, low-latitude countries, would be seriously challenged as climate rises 3*C than normal. The richer, higher latitude countries have greater capacity to adapt to the changing climatic conditions.

Climate changes affect agricultural production by causing variation in the timing and intensity of rainfall and shift in temperatures and carbon dioxide concentrations. As a result of climate change, crops normally seen growing in the south of Europe will be able to be grown further north. This would allow more sweet-corn, grapes, sunflowers, soya and maize to be grown in Britain. In Scotland, livestock farming could become more suitable. At the higher latitudes warmer temperatures are predicted to lengthen and increase the intensity of the growing season. But more CO2 and a major temperature rise could cut yields by around 10% later in the century.

 

How Predictable Has Earth’s Climate Been?

In the 1970s, when we had fairly stable climate conditions, there were speculations that the earth could be going into a very cold period. This proved to be incorrect because temperatures warmed up and the global warming mantra kicked off.

We experienced a period of severe weather conditions after this period, and then we started hearing ‘climate change’ all over the world.

The question now is this: have we really been able to correctly predict what the earth’s weather is going to be, or are we simply figuring out words to falsely predict our planet’s weather? It just seems as though the earth is simply following a systematic pattern or cycle that we have not been able to correctly understand.

We really have to admit that the global warming exponents have been very flexible and adaptable about the answers given to bugging questions concerning our earth’s climate.

Climate-Change

Recently, we have had a new phrase in our climate change dictionary: Global Climate Disruption. It has been said that climate change is directly related to the frequency of hurricane occurrence on the earth.

This raises another question, how then do we explain some really weird events in the earth’s weather that took place in the early 1930s and those hurricanes that happened before we started naming them?

In fact, so many of the predictions concerning climates have proved false, leading us to wonder what premeditates those climate alarms.

Well, we can only conclude that the earth has been going through series of cycles in its climate, and until we come to understand it, we can only speculate at best.

Climate Change – A Brief Overview

The term climate change has gained more usage in the last few decades when more and more concerned citizens become acutely aware of the changes in climate that are happening in their area. Many believe that the changes in the climate are direct consequences of human activities that have boomed over the last century. Here’s a quick look at what is climate change.

So what exactly is climate change? When people are talking about climate change, they’re talking about exactly that – the changes that happen in the climate. These changes are caused when natural processes like volcanic eruptions or the cyclic changes in solar activity give direct impact to the climate system. However, it is a general consensus now that the recent climate change is caused by human activities.

Are we really causing climate change? The climate has changed throughout the history of the world – the ice age showed us that. However, with the increase of industrial activities by human in the past century or so, climate change has been attributed to human activities. Burning of fossil fuels, increasing number of coal-fired power stations and major deforestation all contribute to the release of greenhouse gas. This gas forms a blanket over the Earth and traps heat, causing average temperature to increase and therefore warming certain parts of the world.

Is climate change that bad? If unaddressed, yes. Climate change will cause excessive heat on the Earth’s surface. This in turn will melt glaciers and causes sea level to rise, flooding lower landed areas. There will be more carbon dioxide content in the air and this can affect the natural make up of crops and plants’ growth, throwing it out of scale.

Scientists around the world are working hard in addressing climate change so that it can be contained and not disrupt the Earth’s natural temperature and balance.

Tips To Survive Severe Storms

With climate change has come increasing weather disturbances, not only for those living in the coastal parts of the cities, but inland dwellers too. When there is a warning for a hurricane or a severe storm, there are important tips to abide by that will ensure that the effect of the disaster is at least minimal on your home.

Tornado3

Tip 1 – Always ensure that you keep a rechargeable LED lamp with you, as well as extra batteries for flashlights. Where these are not available, use slow burning candles instead of the scented ones. Make sure they are not left unattended to while sleeping. Watch the kids too when they go near them.

Tip 2 – Before things become too disorganised, contact the local Red Cross or authorities and keep their numbers with you. Find the closest shelter in your neighbourhood especially if you have too much damage in your home.

Tip 3 – Prepare a bag that can contain about two days clothing for each member of the family. Also go with necessary toiletries, while keeping the things a baby might need in a different baby bag.

Tip 4 – If you have more than one car, separate them by a good distance. This will prevent you from losing both cars in the case of any disasters. It is usually a great idea to keep one of them in a shelter while the other is kept away from trees, tall objects or power cables that could fall on them.

Tip 5 – Always stay away from doors and windows and try not to vacate immediately except if the home suffers enough structural damage that is significant to leave it for the storm outside. Else, with minor damages like shattered windows or a fallen tree on the roof, it is safer to remain in there.

The Problem with Dependence on Rainfall in Parts of Africa

It is no longer news that parts of Africa are ravaged by extreme droughts and devastating food shortages. In most of these places, farming is the main stay of the economy.

Over the years, farmers in Africa – both small and large scale have depended on rainfall as the source of water for their large expanse of farmlands. But things are about to change.

drought

With the current change in the world’s climate, leading to infrequent rainfall and unusually long dry seasons, farmers all over the world need to re-position themselves in order to remain productive.

One major way of ensuring they remain in the game is look for alternatives to rainfall by using irrigation in providing water for their farms. The damages already recorded in the severe effects of drought in many parts of Africa really far outweigh whatever costs implementing an irrigation system could take.

Sometimes, the costs involved may not even be astronomical in some environments considering that some farmlands are located beside large bodies of water, like dams, lakes or rivers.

However, the topography of Africa, and the fact that so many of these places that really need help are usually remote, makes them difficult to access for aid during difficult agricultural seasons.

The truth is that African governments need to make long term plans for providing rainfall alternatives for farmers. Large scale farmers also have to learn modern ways of irrigation used in other parts of the world.

The times when rainfall determines crop yield in farms is becoming a thing of the past, and farms all over the world need to rise up to the challenge of drought and food scarcity.

How Plants Can Survive Climate Change

With climatic change plants are now in real danger of facing increased and unusual temperatures in the near future. But there seems to be hope, with the discovery that certain plants could adapt to climates by activating and deactivating certain genes that better preserve them in such conditions.

Epigenetics

The ability to activate and deactivate genes depending on climatic conditions is under the field of study called Epigenetics. Epigenetics is the study of chemical markers that bring about temporary genetic changes as a result of external factors.

What causes activating or deactivating of genes?

The activation and deactivation of genes by plants take place under certain conditions of stress. In drought conditions for instance, a plant may have to adapt to the limited available water.

Epigenetics unlike the genetic adaptation we already know takes place very fast; as evidenced in the study of A. thaliana that can produce a new generation every eight weeks.

The significance of diversity in genes during climatic change

The study of Epigenetics and gene diversity preserve seeds with desirable qualities. Qualities that enhance the survival of the plant in extreme climate conditions will now be readily available.

What this means is that scientists will no more have to go to the wild in search of seeds with the ability to withstand heat, drought or change in climatic conditions. Epigenetic variations will now be available in genetic labs.

Although this research is still in its infancy, it still promises to reveal another interesting aspect of plant breeding.

Petition for a Sustainable Use of Land

 

The land is a limited resource. However, Europe continues to utilize more and more throughout the world. Europe is the continent that more than anything else in the world depends on imported resources and products from other countries, to support its economy by using a portion of land totaling approximately one and half times its size.

The persistence of this situation of over-exploitation of land is due to a variety of social and environmental problems worldwide, ranging from increased food prices, the loss of biodiversity, climate change. To change things, it is important for Europe to measure how much of the territory of the planet it uses to support its economy and puts in place effective policies for the efficient use of natural resources.

In the month of June, a group of experts will begin to discuss how to measure the impact of consumption of goods and services in Europe in relation to the use of global territory. The Friends of the Earth offer European citizens to sign a petition addressed to the European Commissioner for the Environment, Janez Potocnik, who is responsible for this institutional initiative.

 

The Great Barrier Reef is Threatened

 

SYDNEY – UNESCO on Saturday urged Australia to take urgent measures to protect the Great Barrier Reef boom of mining and gas, threatened to add to the list of sites “at risk” of heritage.

Australia has launched an unprecedented program of investment in the exploitation of energy resources to meet the growing demand in Asia, with a pipeline of 450 billion Australian dollars (435 billion).

The largest coral reef in the world is not yet sufficiently affected to be declared in danger, but Unesco estimates that the number and size of projects, including those relating to liquefied natural gas (LNG), tourism exploitaion and mining represent a real threat.

The decline in water quality and climate change are major issues but it is “essential to limit economic development that threatens the strength of the reef,” said UNESCO.

The committee has threatened to close the site “in danger” if some of the biggest projects were not abandoned, giving eight months in Australia to adopt a more sustainable development charter.

The Australian Minister for Environment Tony Burke acknowledged that the reef was exposed “to risks of climate change and the impact of coastal development” and that Canberra was “well aware”.

“Despite the complexity of these issues, we are determined to cope by taking a series of provisions on the coast and marine environment,” said Burke.

Campbell Newman, the Premier of Queensland, who is locally responsible for the barrier, reminded him that his region was living in coal mining and that there was no question of endangering the future Economic Queensland but it would protect the environment.

The environmentalists have called for an awareness of the Government, the Australian Conservation Foundation (ACF) whereas the risk of being pinned by Unesco would be a “national disgrace” for the country.

A UNESCO mission came in March estimate the impact of the proposed natural gas development on Curtis Island has found serious consequences for the environment of the boom “unprecedented” Mining Development.

The port of Gladstone, a hub for exporting coal to Japan, India, North Korea and China, has undertaken massive expansion work which according to environmentalists, destroys Navy life.

UNESCO has estimated that environmental measures taken by the Government in Gladstone and Curtis Island, with an LNG project for an annual production of 12 million tons, were clearly insufficient to protect the reef.

Mr. Burke acknowledged that there were “significant decisions” to be taken regarding the future of the reef, but noted that some projects concern UNESCO had been revised downward since their visit.
