Spewing too much carbon dioxide into the atmosphere could shut down the major ocean current that ferries warm water to the North Atlantic, new climate simulations suggest. While not as extreme as the doomsday scenario portrayed in the movie The Day After Tomorrow, such a shutdown could cause wi...
The concentration of heat-trapping CO2 pollution in the atmosphere has passed the 400 parts per million (ppm) threshold in Antarctica for the first time in at least 800,000 years, and possibly as long as four million years, scientists reported this week.
The new measurements, reported by British an...
Making predictions about climate variability often means looking to the past to find trends. Now paleoclimate researchers from the University of Missouri have found clues in exposed bedrock alongside an Alabama highway that could help forecast climate variability. In their study, the resea...
Earth recently hit several remarkable records — but not in a good way
The amount of carbon dioxide gas, a global warming pollutant, has risen to the highest level in at least 800,000 years. Monthly average Arctic sea ice extent in March was the lowest in the satellite record. So far, 2015 has seen ...
Growth has accelerated 70 percent in some European varieties since the 1960s. Average tree growing seasons increased 10.8 days since the turn of the 20th century
Trees live a long time. There are trees alive on Earth today that were sprouting during the reign of England's Henry VIII. There are...
NASA is preparing a July 1 launch for its first satellite dedicated to measuring atmospheric levels of carbon dioxide, a greenhouse gas that plays a key role in climate change.
CO2 levels have reached their highest point in at least 800,000 years, according to the US space agency.
The Orbi...
Increasing carbon dioxide in the world's oceans could hamper fishes' eyesight, slowing their reaction times and leaving them vulnerable to predators or unable to hunt, new research has shown.
Experts say it adds to the existing evidence that ocean acidification will be bad for marine...
Pollution from China travels in large quantities across the Pacific Ocean to the United States, a new study has found, making environmental and health problems unexpected side effects of U.S. demand for cheap China-manufactured goods.On some days, acid rain-inducing sulphate from burning of fossil f...
When the U.S. Navy sailed an imposing fleet near Hawaii that was powered in part by algae and used cooking grease, environmentalists weren't the only ones who were thrilled.
Executives at bioenergy startups in the San Francisco Bay Area, Chicago and elsewhere — and the venture capitalis...
About 55.5 million years ago, geologically rapid emission of a large volume of greenhouse gases at the Paleocene-Eocene boundary (PETM) led to global warming of about 5oC, severe ocean acidification, and widespread extinction of microscopic organisms living on the deep-sea floor (foraminifera).
A s...
