A Quote by Hans von Storch

Because of the inherent time lag in the climate system, the greenhouse gases that have already been pumped into the atmosphere will undoubtedly lead to a certain increase in temperature in the coming decades.
The models that have been constructed agree that when, as has been predicted, the level of carbon dioxide or its equivalent in other greenhouse gases doubles from pre-Industrial Revolution concentrations, the global average temperature will increase, and that the increase will be 1.5 to 4.5 degrees Celsius or 3 to 8 degrees Fahrenheit... In Dallas, for instance, a doubled level of carbon dioxide and other gases like methane, would increase the number of days a year with temperatures above 100 degrees from 19 to 78 each year.
The basic scientific conclusions on climate change are very robust and for good reason. The greenhouse effect is simple science: greenhouse gases trap heat, and humans are emitting ever more greenhouse gases.
The largest source of greenhouse gases in the coming decades will not be the US, Western Europe and Japan, but the developing economies of East Asia, Latin America and Eastern Europe. The coming eruption of carbon emissions from the poor world will dwarf any reductions in the North.
Those who deny human-caused climate change offer no compelling evidence to better explain the undeniable rise in atmospheric concentrations of greenhouse gases and global temperature.
Climate change is a consequence of the build up of greenhouse gases over the past 200 years in the atmosphere, and virtually all these emissions came from the rich countries.
The basic science is very well established; it is well understood that global warming is due to greenhouse gases. What is uncertain is projections about specifics in the next few decades, by how much will the climate change.
I think it's crazy for us to play games with our children's future. We know what's happening to the climate, we have a highly predictable set of consequences if we continue to pour greenhouse gases into the atmosphere.
The climate's sensitivity to greenhouse gases is considerably lower than the Intergovernmental Panel on Climate Change claims - so much lower, in fact, that the warming we would expect from doubling the amount of carbon dioxide in the atmosphere would be quite modest and offer very little risk.
Extreme weather like the droughts in Russia, China and Brazil and the flooding in Pakistan and Australia [in 2010] have contributed to a level of food price volatility we haven't seen since the oil crisisof 40 years ago. Unfortunately, this could be just a taste of things to come because in the next few decades the build-up of greenhouse gases already in the atmosphere could greatly increase the risk of droughts, flooding, pest infestation and water scarcity for agriculture systems already under tremendous stress.
We have no choice: we must protect Arctic ice, enable it to continue to act as an essential temperature regulator for the planet, avoid the catastrophic rise in sea levels that would result from the ice melt, and stop the disappearance of permafrost releasing irreversible quantities of greenhouse gases back into the atmosphere.
Climate change is not the fault of man. It's Mother Nature's way. And sucking greenhouse gases from the atmosphere is too limited a solution. We have to be prepared for fire or ice, for fry or freeze. We have to be prepared for change.
Warming of the climate system is unequivocal...most of the global average warming over the past 50 years is very likely due to anthropogenic greenhouse gases increases.
There is universal consensus among experts that the earth's atmosphere is heating up - and that we are responsible for it by putting carbon dioxide in the atmosphere. We also know that the consequences of global warming are catastrophic. But how do we make sure that all countries reduce greenhouse gases?
Geologists and paleo-climatologists know that in the past the Earth's temperature has been substantially warmer than it is today, and that this warming has occurred under purely natural circumstances. Until we can say precisely how much of the current global warming and greenhouse gas increase is the result of this normal temperature cycle, we will not be able to measure how much human activity has added to this natural trend, nor will we be able to predict whether there will be any lasting negative effects.
Agriculture is one of the biggest causes of greenhouse gases in the atmosphere. Cars? Planes? Trains? Nope. Cow farts.
Though Africa is not responsible for emitting greenhouse gases, it is suffering the consequences of climate change.
