Some Crabs Are Losing Their Sense of Smell as Oceans Acidify
Commercially valuable Dungeness crabs lose their sense of smell as the ocean absorbs more carbon dioxide and becomes more acidic
Chelsea Harvey covers climate science for Climatewire. She tracks the big questions being asked by researchers and explains what's known, and what needs to be, about global temperatures. Chelsea began writing about climate science in 2014. Her work has appeared in The Washington Post, Popular Science, Men's Journal and others.

Commercially valuable Dungeness crabs lose their sense of smell as the ocean absorbs more carbon dioxide and becomes more acidic

High temperature records have been set from Portugal to Thailand as heat waves fueled by climate change have arrived early this spring

Many bird species are producing fewer offspring as global temperatures rise, and larger migratory species are particularly affected

Melting sea ice is opening new pathways through the Arctic such as the famed Northwest Passage. But it is also reducing visibility and potentially causing delays

Communities in certain spots around the world, such as Afghanistan, Papua New Guinea and Central America, are likely to experience record-breaking heat events but may not be prepared

Greenland’s Steenstrup Glacier doubled its annual ice loss in just a few years, thanks to warm ocean water

Sea levels off the southeastern U.S. have risen more than a centimeter a year over the past decade—about triple the global average—and the effects on communities near the Gulf of Mexico and Atlantic Ocean already are being observed...

Evidence that ancient glaciers retreated more than a quarter-mile a day is a worrisome sign that glaciers today could melt—and contribute to sea-level rise—faster than was thought...

A new study documents the mysterious presence of five banned chlorofluorocarbons, chemicals that not only deplete the ozone layer but also contribute to global warming

A new study debunks the idea that solar geoengineering is a temporary measure to reduce warming and meet climate targets

Fires in North America and Eurasia spewed record-shattering amounts of CO2 in 2021

Climate change is likely at least partially to blame for an uptick in the size and frequency of algal blooms in parts of the world’s oceans

Antarctica’s massive Thwaites Glacier is melting more slowly than previously thought but also may be more susceptible to even small amounts of ice loss

At least 15 million people worldwide live in the flood paths of lakes that form as mountain glaciers melt and that can abruptly burst their banks

Scientists and companies are scrambling to find new ways to squeeze more rain from the skies as climate change intensifies drought

The transformative social change needed to limit global warming to 1.5 degrees Celsius isn’t happening fast enough, experts say in a new report

New research from artificial intelligence projects that global warming will hit the threshold of 1.5 degrees Celsius somewhere between 2033 and 2035

A pair of studies raise concerns that the Amazon rain forest may be approaching a point of no return

Temperatures in north-central Greenland are the highest in at least a millennium, contributing to ice melt that is raising global sea levels
