Yellowstone spawned twin super-eruptions that altered global climate
A new geological record of the Yellowstone supervolcano’s last catastrophic eruption is rewriting the story of what happened 630,000 years ago and how it affected Earth’s climate. This eruption formed the vast Yellowstone caldera observed today, the second largest on … Continue reading
Volcanic eruptions drove ancient global warming event
A natural global warming event that took place 56 million years ago was triggered almost entirely by volcanic eruptions that occurred as Greenland separated from Europe during the opening of the North Atlantic Ocean, according to new research. Paleontology News … Continue reading

Is Global Warming Fueling Increased Wildfire Risks?
A wildfire rages on in Black Forest, Colorado June 12, 2013. Its thick, bone-dry forests have contributed to the blaze. REUTERS/Rick Wilking Portland State researchers studying centuries-old trees in South America have found a tight correlation between wildfires and a … Continue reading
Human-made aerosols identified as driver in shifting global rainfall patterns
Scientists found that aerosol particles released into the atmosphere from the burning of fossil fuels are a primary driver of changes in rainfall patterns across the globe. Geology News — ScienceDaily

Weathering of rocks a poor regulator of global temperatures
Evidence from the age of the dinosaurs to today shows that chemical weathering of rocks is less sensitive to global temperature, and may depend on the steepness of the surface. The results call into question the role of rocks in … Continue reading

Pattern of mammal dwarfing during global warming
More than 50 million years ago, when the Earth experienced a series of extreme global warming events, early mammals responded by shrinking in size. While this mammalian dwarfism has previously been linked to the largest of these events, new research … Continue reading
Louisiana wetlands struggling with sea-level rise 4 times the global average
Without major efforts to rebuild Louisiana’s wetlands, particularly in the westernmost part of the state, there is little chance that the coast will be able to withstand the accelerating rate of sea-level rise, a new study concludes. Geology News — … Continue reading
