Models show intensifying wildfires in a warming world due to changes in vegetation and humidity; only a minor role for lightning

A new study reveals that climate change is driving intensifying wildfires by altering vegetation and humidity levels, but not significantly impacting lightning strikes. The simulations predict a 14% increase in global area burned by fires annually with every degree of global warming.

New research uncovers how climate and soil shape tree and shrub wood density across ecosystems

A recent study found that climate factors play a more dominant role in determining wood density for tree species than soil characteristics, while both factors equally influence shrub species. The research provides new insights into vegetation responses to environmental factors, with implications for improving ecosystem predictions.

Climate change will lead to wetter US winters, modeling study finds

A new study led by University of Illinois Chicago scientist Akintomide Akinsanola found that most Americans can expect wetter winters in the future due to global warming. Winter precipitation and extreme weather events are expected to increase across most of the country, with six regions experiencing more frequent very wet winters.

West Antarctic ice sheet may disappear by 2300

A Dartmouth-led study projects that Antarctica's glaciers will rapidly retreat and potentially collapse by 2200, increasing global sea levels by up to 5.5 feet by 2300. The researchers used 16 ice-sheet models to refine the projection of ice loss over the next 300 years.

Study finds highest prediction of sea-level rise unlikely

A new study led by Dartmouth researchers questions the rapid polar ice collapse model used in the IPCC's sixth assessment report. The team found that the expected rate of retreat is significantly lower than predicted, making the worst-case scenario less likely, but still dire due to ongoing ice loss from Greenland and Antarctica.

Not the day after tomorrow: Why we can't predict the timing of climate tipping points

A new study shows that predicting exact tipping times for critical Earth system components is challenging due to large uncertainties. The authors identified three primary sources of uncertainty and found that predicted tipping times for the Atlantic Meridional Overturning Circulation (AMOC) ranged from 2050 to 8065.

Tipping risks from overshooting 1.5 °C can be minimised if warming is swiftly reversed

A recent study warns that overshooting 1.5°C of global warming poses significant risks to the Earth's climate system, but swiftly reversing warming can minimize these risks. The study suggests that achieving and maintaining net-zero greenhouse gas emissions by 2100 is crucial to limit tipping risks.
