Climate change is one of the biggest challenges of the 21st century. Changes in temperature and precipitation, an increase in extreme weather events, shifts in seasonal climate patterns, and mostly likely a further rise in sea levels will all take their toll on our human society.
Attempts to limit the effects of climate change are being made at global level. The goal of the EU climate policy, for instance, is to prevent global temperature from climbing more than 2° C by 2050. But even if we were to achieve this goal, we still need to take action and get the right adjustment measures on track now.
Man-made climate change is caused by an increase in greenhouse gas emissions such as carbon dioxide, methane, and others. These gases are emitted into the atmosphere by fossil fuel burning and certain farming practices, where they build up and prevent heat energy from radiating back into space. This principle is very old and throughout Earth history has spared the globe from being completely covered in snow and ice. Today, however, this interplay between the sun’s rays and thermal radiation is increasingly getting out of balance.
