As global warming passes certain limits, dire changes will probably become irreversible, the researchers said, including the loss of polar ice sheets and the death of coral reefs.

In the desert near Agua Dulce, north of Los Angeles, hikers along the Pacific Crest Trail who reached mile marker 502 encountered a cistern of water that smelled bad and tasted worse, with a dead rat floating inside. They got out their filters and refilled their bottles anyway. “Will update if I get sick,” one wrote on a message board to those coming up behind.
The nation’s most prestigious scientific body said Tuesday that it has barred a key White House official focused on climate change, Jane Lubchenco, from participating in its publications and activities for five years.
Deadly floods are slamming the US Heartland. More than 2,000 miles away, dangerous heat is scorching the Pacific Northwest. The same phenomenon is to blame for both.
A massive bend in the jet stream — narrow bands of high winds encircling the Earth — is causing the havoc. In the Northwest, the jet steam has curved far north, allowing hot air to surge into Oregon and Washington. In the Midwest and Appalachia, it’s dipped south, bringing cool from Canada that’s colliding with with tropical air from the Gulf of Mexico, triggering ruinous downpours in Missouri
In recent days Republicans in the US House of Representatives released the first of what will be a six-part policy platform on energy, climate, and conservation. The strategy was the work of the Energy, Climate, and Conservation Task Force (ECC).
On June 10, Las Vegas reached a record daily high temperature of 109 degrees Fahrenheit (43 degrees Celsius), and temperatures of the ground surface itself were higher still. NASA’s Ecosystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) instrument recorded this image of surface temperatures at 5:23 p.m. that day.
By now, few people question the reality that humans are altering Earth’s climate. The real question is: How quickly can we halt, even reverse, the damage? Part of the answer to this question lies in the concept of “committed warming,” also known as “pipeline warming.”
The planet changes quickly: More than half a million acres are burning in New Mexico. A megadrought is shrinking Lake Mead. The Alps are turning from white to green. Development continues to expand, from cities to massive solar farms. All of these changes impact the Earth’s climate and biodiversity. But in the past, such changes have been difficult to track in detail as they’re happening.
That man is George Woodwell, and since 1985, the center he founded has been deeply involved in climate research and policy at home and abroad. Today, it employs nearly 100 scientists and staff, whose work on everything from permafrost to wildfires is shaping our understanding of the world we live in — and what we’re doing to it.
The world cannot adapt its way out of the climate crisis, and counting on adaptation to limit damage is no substitute for urgently cutting greenhouse gases, a leading climate scientist has warned.
