Climate change impacts on hydrogeography
Köppen geiger climate classification
Based on seasonal precipitation and temperature patterns
Where do these projections come from
Climate models
encapsulates the physics of the climate
Make accurate predictions about future carbon dioxide emission levels
General circulation models (GCMs)
CMIP: Coupled model intercomparison project
Represensative concentration pathways RCP:s
Future projections form CMIP6: Shared socioeconomic pathways
Climate change impacts
Climate change can be seen on land, sea and atmosphere. Some impacts are already observed and some will be irreersible for centuries
Sea Ice
Sea level rise and land uplift
The level of the oceans does not rise everywhere at the same rate
Hot extremes
Impacts - heatwaves
Precipitation variability
Increased risk of droughts and floods
water scarcity
infrastructure impacts
Heavy precipitation
Floods
Floods in Finland
100-yr floods decrease in average by 8-22% in 2070-2099
Suurin osa tulvista tulee tapahtumaan syksyisin että talvisin. Tämä johtuu siitä, että vettä tulee satamaan enemmän eikä lunta jää maahan.
Kevät tulee hieman aikaisemmin
Droughts
Drought - water scarcity
Wildifres
