Alaska is warming faster than any other U.S. state, and that’s causing problems, a team of bridge engineers and social scientists explains. The infrastructure bill in Congress would offer some help.

Earth observation satellites can measure millimetre changes in sea level and track deforestation in near-real time.
Australia must treble its emissions reduction targets and reach net-zero emissions by 2035. Without this and other radical global action, the chance to hold warming to well below 2°C will pass us by.
New research shows that permafrost contains huge amounts of particles that make it easier for cloud moisture to freeze. Thawing permafrost is releasing these ice-nucleating particles.
Peat beds around the world hold huge quantities of carbon and keep it from warming the planet. But rising temperatures and over-use could turn them from a brake on climate change into an accelerant.
Three scientists describe the fieldwork they’ve had to delay in 2020 because of the pandemic. These are setbacks not just for their careers, but for the body of scientific knowledge.
The Zimovs want to restore the prehistoric ‘mammoth steppe’ ecosystem and see if it slows down – or even reverses – melting permafrost.
Massive landslides can trigger destructive and deadly tsunamis, and climate change could make them worse.
Peatlands will become a major source of greenhouse gases as the permafrost thaws.
Arctic heat waves were once rare and unusual events. But as their intensity and frequency increase with climate change, their fallout could affect the north — and the planet — for decades to come.
Climate change is thawing permafrost and increasing the risk of these accidents, and the region has fewer of the bacteria that can ‘clean up’ oil spills.
The Arctic is warming about twice as fast as the planet as a whole, with serious consequences. Scientists have been warning about this for decades.
Models have predicted for some time that with every degree of global warming, the Arctic will see double or more.
The wet and low-lying East Siberian Arctic is likely to be a major methane source in the coming decades.
US military leaders have to plan for operations all over the world, so they can’t afford to ignore climate change or debate its causes.
Hundreds of thousands of lakes, rivers and streams in the Arctic exist only because of the permafrost that lies beneath them. The warming Arctic threatens to change that.
Studies show that the Arctic is heating up twice as fast as the rest of the planet.
Climate change has caused a 60-fold increase in active landslides on one Canadian Arctic island.
For everyone from traditional hunters to the military, the National Park Service to the oil industry, climate change is the new reality in Alaska. Government, residents and businesses are all trying to adapt.
While extreme weather conditions represent a considerable challenge globally, some communities have been living with (and adapting to) similar events for centuries.
