Temperature and rainfall extremes in a warming world

By Dr Flora MacTavish Governments, planning authorities, companies and individuals all need information about  the impact of climate change on extreme weather in the future. A recent paper [1] investigates changes in extremes both globally and locally. We can be relatively certain of the signature of climate change on a global or continental scale. On the other hand, estimating changes on a country-wide scale is harder … Continue reading Temperature and rainfall extremes in a warming world
