Climate change

In the last few years, scientific research and knowledge on climate change have progressed substantially, confirming that the current warming of the Earth's climate is very likely to be due to human activities such as the burning of fossil fuels.

What is the state of knowledge on climate change?

Milestone Reports on Climate Change

Climate Change (2007) by IPCC

In 2007, the Intergovernmental Panel on Climate Change (IPCC) reassessed the state of knowledge in its 4^th assessment report (4AR).

Clearly, the Earth’s warming is already having measurable consequences and future impacts are expected to be wide-ranging and costly.

How can we adapt to those changes? Is it possible to limit the extent of climate change and its impacts through mitigation efforts?

Arctic Climate Change (2004) by ACIA

In 2005, the international project Arctic Climate Impact Assessment was completed by the Arctic Council and the International Arctic Science Committee (IASC).

Arctic climate is now warming rapidly and much larger changes are foreseen.

How had the climate changed in the Arctic so far, and what future changes are expected? How will arctic climate change affect the rest of the planet?

Climate Change (2001) by IPCC

In 2001, the Intergovernmental Panel on Climate Change (IPCC) assessed the state of knowledge in its groundbreaking Third Assessment report (TAR).

What was already known in 2001?

Mitigation of climate change

CO₂ Capture & Storage (2005) by IPCC

One possible option for reducing CO₂ emissions is to store it underground. This technique is called Carbon dioxide Capture and Storage (CCS).

How does it work? Could it really help addressing climate change?

The International Panel on Climate Change (IPCC) provides answers in a special report.
