Introduction to Climate Change

Climate Change and its potential impacts

Climate change is a global phenomenon that has impacts on every country, and it is happening now. A rise of global mean temperature by 1.5° to 3.5° C is projected until 2100. Climate is a complex and fragile system, so this seemingly small change has grave implications. To name just some, changes in rainfall, both increases and decreases, are forecasted. Sea levels are projected to rise. The frequency and intensity of extreme weather events (e.g., storms and floods) can be expected.

How will this affect the world we live in?

Climate change poses a challenge for many aspects of our daily life.
The ecosystems we rely on are under pressure. Animal species may die out or migrate because their life depends on specific climate factors, including temperature and rainfall. Plant species are affected, too, and biodiversity is under threat.

Human health and survival is endangered as water security and food security are affected by changes in temperature and rainfall patterns. Also, extreme weather events, including storms and floods, put human infrastructure and life at direct risk.

Economies and societies need to adapt as the core variables that they are based on are changing:
