What will Alaska look like in 30 years?
In the next 30 years, Alaskan average annual temperatures are projected to increase another 2-4 degrees Fahrenheit. This warming trend is causing intensified flooding, sea level rise, warming oceans, less and thinner sea ice, coastal erosion, and thawing permafrost.
What will Alaska look like after global warming?
Alaskans are already seeing earlier spring snowmelt, widespread glacier retreat, drier landscapes, and more insect outbreaks and wildfires because of climate change. Arctic summer sea ice is receding faster than previously projected and is expected to virtually disappear before mid-century.

What will happen if permafrost melts due to global warming?
Melting Siberian permafrost is turning parts of the tundra into muddy landscapes, causing the local flora to disappear and the wildlife that feeds on it to starve. Furthermore, when the permafrost beneath water bodies, such as lakes, melts, the water seeps into the ground and disappears, causing droughts.
Is Siberia permafrost melting?
Siberia’s permafrost melt is causing swamps, lakes, making land difficult to live on. The land affected becomes largely useless for agriculture and infrastructure.
