Rocky Mountain forests burning more now than any time in the past 2,000 years
Scientists studied charcoal layers in the sediment of lake beds across the Rockies to track fires over time. They found increasing fire activity as the climate warmed.

Climate change is making Rocky Mountain forests more flammable now than at any time in the past 2,000 years
Scientists used charcoal layers in the sediment of lake beds across the Rockies to track fires in each area. Combined with other data, it tells a story of increasing fire activity as the planet warms.

The Arctic hasn't been this warm for 3 million years – and that foreshadows big changes for the rest of the planet
Extreme shrinkage of summer sea ice is just the latest evidence of rapid Arctic warming – and what happens in the Arctic doesn't stay there.
