No, Arctic Sea Ice Has Not Recovered, Scientists Say

No, Arctic Sea Ice Has Not Recovered, Scientists Say

Arctic sea ice extent has reached its seasonal minimum, dropping to the sixth-lowest level in the 35-year satellite record. This year’s melt represents a significant gain in sea ice extent from last year, when the ice cover plummeted to a record low, but scientists cautioned that long-term trends are what is most important, with most projections st… Read More

Arresting First Responder Images of Colorado Flooding

Arresting First Responder Images of Colorado Flooding

After receiving nearly a year's worth of rain in just one week, portions of Colorado are suffering from devastating flooding. In the hardest-hit areas of Colorado's Front Range, including the city of Boulder, the National Guard has been airlifting people who have been cut off from surrounding communities by raging floodwaters.… Read More

Human Fingerprints Visible in Atmospheric Changes

Human Fingerprints Visible in Atmospheric Changes

Human-caused greenhouse gas emissions are like a cat burglar. They’re invisible and move noiselessly. However, they’re prone to leaving fingerprints, and scientists, acting as detectives, have been looking for those fingerprints. The latest discovery, announced Monday in a paper in the Proceedings of the National Academy of Sciences, makes the case… Read More

Flood-Ravaged Boulder, Colo., Sets Annual Rainfall Record

Flood-Ravaged Boulder, Colo., Sets Annual Rainfall Record

With 30.12 inches of rain and counting, more than half of which fell since Sept. 9, the city has already eclipsed its previous annual record of 29.93 inches, which was set in 1995. The average yearly precipitation (rain and melted frozen precipitation) in Boulder is 20.68 inches. The annual precipitation record is especially noteworthy since befor… Read More

Climate Change Threatens Southern Africa’s Vital Crops

Climate Change Threatens Southern Africa’s Vital Crops

The study, published by the International Food Policy Research Institute (IFPRI), and with contributions from scientists in countries across the southern Africa region, uses available data and a variety of models to examine likely agricultural developments, particularly related to crops, in the period to 2050. Agriculture is the primary source of … Read More

Parts of Europe Heating Faster than Global Average

Parts of Europe Heating Faster than Global Average

Temperatures in some parts of Europe have already increased by more than 2C in the last 60 years with changes in local climate allowing new crops to be grown. An example is the new wine growing area in southern England, which this year is celebrating its best ever grape harvest. Hundreds of acres of new vineyards are being planted to take advantag… Read More

Colorado’s ‘Biblical’ Flood in Line with Climate Trends

Colorado’s ‘Biblical’ Flood in Line with Climate Trends

It will take climate scientists many months to complete studies into whether manmade global warming made the Boulder flood more likely to occur, but the amount by which this event has exceeded past events suggests that manmade warming may have played some role by making the event worse than it would have otherwise been.… Read More

Channels of Meltwater Detected in Antarctic Glacier

Channels of Meltwater Detected in Antarctic Glacier

The study revealed that much of the meltwater travels through channels resembling river valleys beneath the ice sheet. One of the channels observed was about 2,000 feet wide, melting about 2.4 inches of ice per day, in much the same way that a meandering river gradually erodes adjacent land. If the melt rate were to stay steady throughout the cour… Read More
