Climate Change – The Problem

Greenhouse gases in the atmosphere trap heat on Earth and increase the global average temperature. This is a very good thing – if there were no greenhouse gases in our atmosphere, basic physics suggests the mean temperature on Earth should be around -20°C, not the pleasant 15°C that allows life to flourish.

Many human activities are now increasing the amount of greenhouse gases in the atmosphere, and this is warming our planet. As the Earth warms, the climate changes. It is impossible to predict, at this stage, precisely what changes will occur. However, according to the United Nations Intergovernmental Panel on Climate Change, scientists are extremely concerned about the possibility of more floods, heatwaves, hurricanes and droughts, as well as increased sea levels resulting from the melting of polar ice caps. The impacts of these changes on human civilizations could be immense. For instance, it may create many millions of "climate refugees" from low-lying nation-states, as well as a marked increase in the frequency of major climate-related catastrophes such as the hurricanes which recently devastated much of South-Eastern USA.

While the precise impacts are unpredictable, the overwhelming majority of scientists agree that we are taking enormous risks with our climate. Our greenhouse gases are creating an extraordinarily interesting experiment in climate science, but the results may come too late for the only planet we have to live on.

Scientists and economists broadly agree that we should reduce carbon emissions by as much as 60% by around 2050 in order to contain the risks of major environmental, social, and economic upheaval. Even with such reductions, damage from climate change will be incurred. Yet, driven in part by the extraordinary growth in China, global emissions are now growing more rapidly than ever before.

Why is the problem so difficult? Solving it requires collective action – getting people together – on a scale comparable to that of a world war. Overcoming the problem requires trust, strong analytics, intelligent policy backed by extraordinary collective negotiating skills, and innovative business solutions. Effective incentives and policy are crucial, and the links below provide more detail on the social scientific research into climate change:
