Mammals Shrank During Ancient Global Warming Event

Between 56 million and 53 million years ago, Earth experienced a series of extreme global warming events that radically altered life on the planet. During the first event, the Paleocene-Eocene Thermal Maximum (PETM), carbon levels spiked and temperatures increased as much as 8 degrees Celsius (14.4 degrees Fahrenheit). A second event, known as the Eocene…

On climate change, Scott Pruitt causes an uproar — and contradicts the EPA’s own website

Scott Pruitt, the nation’s top environmental official, strongly rejected the established science of climate change on Thursday, outraging scientists, environmentalists, and even his immediate predecessor at the Environmental Protection Agency. “I think that measuring with precision human activity on the climate is something very challenging to do and there’s tremendous disagreement about the degree of impact,…

Congress May Shift Climate Research Away from NASA

Lawmakers are remaking NASA in order to leave parts of the agency’s earth science program untouched but remove its climate change research. It’s still unclear exactly how lawmakers plan to transform NASA’s mission, but Republicans and Trump administration officials have said they want the agency to focus on deep-space missions and away from climate change…

Understanding the Link Between Climate Change and Extreme Weather

Changes in Extreme Weather and Climate Events Scientists study many aspects of change in extreme weather and climate events. These include: Frequency: Are events occurring more often than they did in the past? Intensity: Are events getting more severe, with the potential for more damaging effects? Duration: Are events lasting longer than "the norm"? Timing: Are events occurring earlier…

Endangered Australasian marsupials are ancient survivors of climate change

In a new paper, published in Scientific Reports, an international team of researchers has analysed fossils and DNA from living and recently extinct species to show that conservation sensitive Australasian marsupials are much older than previously thought. "We used bandicoots as a model to examine the radiation of marsupials relative to climate change through time.…

Climate Change Does Have Some Winners, Like Brain-Eating Parasites

It’s a myth there are no big winners from climate change besides fossil fuel companies. According to one study, global warming is doubling bark beetle mating, triggering up to 60 times as many beetles attacking trees every year. The decline in creatures with shells thanks to ocean acidification “could trigger an explosion in jellyfish populations.”…

Human-caused climate change increased the severity of many extreme events in 2014

Human activities, such as greenhouse gas emissions and land use, influenced specific extreme weather and climate events in 2014, including tropical cyclones in the central Pacific, heavy rainfall in Europe, drought in East Africa, and stifling heat waves in Australia, Asia, and South America, according to a new report released today. The report, "Explaining Extreme…
