There have been a number of studies which show that we can expect more extreme rainfall with a global warming . Hence, there is a need to increase our resilience to more rainfall in the future. We can say something about how the rainfall statistics w

Since 1979 we’ve been measuring the extent and area of sea ice in the Arctic using satellites. This is what we’ve found (data from NSIDC, the National Snow and Ice Data Center): Obviously there’s a strong seasonal cycle,
