How mangroves help keep the planet cool

Coastal scientists have developed a new global framework to more accurately assess how mangroves along different types of coastlines from deltas to lagoons store carbon in their soil. They found that previous studies have underestimated the blue carbon levels in mangroves by up to 50 percent in some regions and overestimated levels by up to…

Global warming can turn monarch butterflies’ favorite food into poison

LSU researchers have discovered a new relationship between climate change, monarch butterflies and milkweed plants. It turns out that warming temperatures don't just affect the monarch, Danaus plexippus, directly, but also affect this butterfly by potentially turning its favorite plant food into a poison. Bret Elderd, associate professor in the LSU Department of Biological Sciences, and…

Hurricanes: Stronger, slower, wetter in the future?

Scientists have developed a detailed analysis of how 22 recent hurricanes would be different if they formed under the conditions predicted for the late 21st century. While each storm's transformation would be unique, on balance, the hurricanes would become a little stronger, a little slower-moving, and a lot wetter. In one example, Hurricane Ike --…

Climate change is transforming the Great Barrier Reef

A new study published online today in Natureshows that corals on the northern Great Barrier Reef experienced a catastrophic die-off following the extended marine heatwave of 2016. "When corals bleach from a heatwave, they can either survive and regain their colour slowly as the temperature drops, or they can die. Averaged across the whole Great Barrier…

Large beetles are shrinking, thanks to climate change

If you’re afraid of giant insects, climate change has a silver lining for you. A new study shows that as temperatures have increased over the past century, the world’s biggest beetles may have been shrinking, some downsizing by as much as 20% in 45 years. This new work “is a powerful demonstration of how climate…

The Hole in Earth’s Ozone Layer Is Healing

Efforts to heal the hole in Earth's ozone layer over Antarctica appear to be paying off, according to a new, first-of-its-kind study that looked directly at ozone-destroying chemicals in the atmosphere. Earth's ozone layer protects the planet's surface from some of the sun's more harmful rays that can cause cancer and cataracts in humans, and…

Climate change drives collapse in marine food webs

A new study has found that levels of commercial fish stocks could be harmed as rising sea temperatures affect their source of food. University of Adelaide scientists have demonstrated how climate change can drive the collapse of marine "food webs." Published in the open access journal PLOS Biology, the study's lead author PhD student, Hadayet Ullah…
