The team found that climate change increased burn probability and led to larger, more frequent fires in wetter areas while doing the opposite in more arid locations. In areas of intermediate soil moisture, the effects of climate change and fire suppression varied in response to local trade-offs between flammability and fuel loading.
The scientists were surprised that climate change could decrease the severity of fires under certain conditions, but Tague offers an explanation. “Climate change can reduce the growth and development of fuels, particularly in more arid sites,” she said.
These are crucial insights in our efforts to understand and manage wildfires.
2020 was the worst wildfire year on record for the Western United States, with 10 million acres burned, 10,000 structures destroyed, and an estimated 20

The quiet, sleepy, yet mesmerising village of Mawsynram trounced Cherrapunji to become the wettest place in the world. Mawsynram receives over 10,000 millimetres of rain in a year.
However, new research co-authored by Princeton University shows that migration to the coast could actually accelerate in some places despite sea-level change, contradicting current assumptions.
The research, published in Environmental Research Letters, uses a more complex behavioral decision-making model to look at Bangladesh, whose coastal zone is at high risk. They found job opportunities are most abundant in coastal cities across Bangladesh, attracting more people whose agricultural income opportunities decline in other parts of the country. Meanwhile, the populations already living along the coast tend to stay, as floods increase their losses but few better alternatives are present elsewhere.
“We tend to think that rising sea levels will drive people away from the coasts, but here we show a plausible story where they don’t,” said lead author Andrew R. Bell, assistant professor of environmental studies at New York University.
