Past 12 Months Tied for Warmest on Record

Past 12 Months Tied for Warmest on Record

April capped a 12-month period that tied the warmest such stretch on record, according to data released Tuesday. That period, going back to May 2014, tied the previous record holder, the 12 months from April 2014 to March 2015. Of the 10 warmest 12-month periods on record, nine occurred in the past two years, most of them in back-to-back… Read More

Take a Look at One of the First Climate Models In Action

Climate models, they just don’t make ‘em like they used to. Of course, that may not be a bad thing. Like an Atari to an Xbox One, a Nokia brick to an iPhone 6, climate models have come a long way since their early predecessors. In a video recently published by Lawrence Livermore Laboratory, you can see just much of an update computer-run models … Read More

Heat is Piling Up in the Depths of the Indian Ocean

Heat is Piling Up in the Depths of the Indian Ocean

The world’s oceans are playing a game of hot potato with the excess heat trapped by greenhouse gas emissions. Scientists have zeroed in on the tropical Pacific as a major player in taking up that heat. But while it might have held that heat for a bit, new research shows that the Pacific has passed the potato to the Indian Ocean, which has seen an … Read More

Canada is planning to cut its greenhouse gas emissions 30 percent below 2005 levels over the next 15 years, following the European Union and the U.S. in setting an emissions reduction target ahead of the Paris international climate negotiations in December. … Read More

May CO2 Peak Shows Trend Is Up, Up, Up

May CO2 Peak Shows Trend Is Up, Up, Up

Any day now, carbon dioxide levels in the atmosphere will reach their annual peak in a cycle driven by the collective inhale and exhale of the world’s plant life. But because of the extra CO2 pumped into the air by human activities, this year’s peak will be higher than last year’s, which was higher than the year before that — a sign of the unabated… Read More

El Niño Gains Momentum, Could Bring Warmest Year

El Niño Gains Momentum, Could Bring Warmest Year

The weak El Niño that has been in place since February seems to be gaining steam, with U.S. forecasters betting it will hang around through the end of the year, increasing the odds that the event could help make 2015 the warmest year on the books. “If El Niño continues to evolve and possibly strengthen throughout the year as the Climate… Read More

The Bright Side of 13 Years of Clouds in 1 Map

The Bright Side of 13 Years of Clouds in 1 Map

Cloudy days can be a bit of a downer. But when you add them all from nearly 13 years of measurements, the bright side becomes more apparent. NASA Earth Observatory just published a map that uses data collected between July 2002 and April 2015 to give an unparalleled view of the world’s cloudy (and sunny) spots. One thing that’s immediately apparent… Read More

A Global Milestone: CO2 Passes 400 PPM

A Global Milestone: CO2 Passes 400 PPM

Another month, another carbon dioxide record. This time the record extends beyond the rocky slopes of Mauna Loa, Hawaii, home to the most storied carbon dioxide record, and includes 39 other sites around the globe to paint a troubling picture of a greenhouse gas rise with no signs of slowing down. For the first time since record keeping began … Read More
