El Niño is Kinda Sorta Maybe Here

El Niño is Kinda Sorta Maybe Here

El Niño watchers, rejoice (maybe). A weak El Niño has formed (sorta). On Tuesday, researchers at the International Research Institute for Climate and Society said a borderline El Niño is upon us, with the odds for further development increasing throughout the fall and winter. This El Niño has played a game of hide and seek since an El Niño Watch… Read More

Another Year, Another Record High for Greenhouse Gases

Another Year, Another Record High for Greenhouse Gases

The numbers are in and in case there was any doubt, it looks like 2013 was another recordsetting year for greenhouse gases. The atmosphere is home to more warming gases than at any other point since industrialization. And carbon dioxide, the main culprit, is causing oceans to acidify at a rate unseen in at least 300 million years. The news comes c… Read More

NASA Releases Blizzard of Precipitation Data

NASA Releases Blizzard of Precipitation Data

Have you been itching to see the most detailed collection of precipitation data ever pulled together? (Join the club) Well, you’re in luck. NASA has just released a vast trove of snow, rain, hail and more liquid measurements from a satellite launched earlier this year. In late February, NASA and an international cohort of space programs launched t… Read More

UN Highlights Climate Big Data Ahead of Summit

Data is buzzing around us all the time, and whether you realize it or not, you utilize data everyday, be it how much your daily cup of coffee costs or how long it takes to get to work. Now imagine doing that on a much bigger picture, organizing millions of pieces of information and making it useful. That’s exactly what scientists are up to when th… Read More

Climate Change Ups Odds of a Southwest Megadrought

Climate Change Ups Odds of a Southwest Megadrought

If you think the drought in California is bad, you ain’t seen nothing yet. New research indicates that climate change is giving a boost to the odds of long-term drought across the Southwest. The research, published Thursday in the Journal of Climate, puts the chances of a megadrought lasting 35 years or longer at up to 50 percent in the region. It… Read More

Crowdsourced Photos Provide Drought Snapshots

On May 24, a roiling dust cloud enveloped a desolate stretch of road in Prowers County, a rural county in southeast Colorado. The county and surrounding area had been deeply mired in drought for more than 2 years and the photo bore proof of just what drought looked like to its residents. The short note accompanying the photo added more context: “Ph… Read More

Visualize It: Old Weather Data Feeds New Climate Models

Visualize It: Old Weather Data Feeds New Climate Models

In the 1930s, there were no computers to run climate models or record weather observations. Instead, weather reports were written or typed on typewriters and forecast maps were drawn by hand. Those observations from the past contain valuable data that can help scientists better understand what the climate may look like in the future. But gathering… Read More

Here’s How Arctic Sea Ice Could Shrink Even More

Here’s How Arctic Sea Ice Could Shrink Even More

Climate change is the main driver behind receding Arctic sea ice. As summer ice shrinks further, it’s causing a host of other changes including the growth of large waves in the previously iced-over areas. Those waves could potentially hasten the demise of sea ice, leading to further changes in the fragile region. Changes brought on by global warmi… Read More

New CO2 Satellite Sends First Data Back to Earth

New CO2 Satellite Sends First Data Back to Earth

NASA’s new carbon dioxide-monitoring satellite just opened its eyes for the first time. Based on the initial data its sending back to Earth, it appears to have 20/20 vision and scientists will soon have plenty more data to analyze. The satellite, dubbed the Orbiting Carbon Observatory-2, or OCO-2, was launched last month as part of an effort to be… Read More

California Has Hottest Start to Year While Midwest Chills

The heat records keep falling for California. The state has had its hottest first seven months of the year, crushing the previous mark. Neighboring states have also baked, though not quite at record levels, helping contribute to both the spread of drought and large wildfires. At the same time, cool weather had a number of Midwest states … Read More

Tornado Outbreaks Could Have a Climate Change Assist

Tornado Outbreaks Could Have a Climate Change Assist

Days with more tornadoes have become more common over the past 60 years, a trend that new research says could have a climate change connection. Understanding the connection between climate change and tornadoes, if any, is one of the most fraught areas of research. But a study released Wednesday posits that changes in heat and moisture content in t… Read More

Indigenous Groups Give Tropical Forests a Carbon Boost

Indigenous Groups Give Tropical Forests a Carbon Boost

Any path forward to reduce the globe’s carbon emissions goes through tropical forests. They serve as a sink to sequester human emissions, but deforestation risks sending those assets up in smoke. A recent report argues that to avoid that outcome, indigenous communities should be involved in forest management. Currently deforestation and land use c… Read More

Toledo’s Algae Bloom in Line with Climate Projections

A two-day ban on drinking water has been lifted in Toledo, Ohio. But the toxic algae bloom that led to the ban is still floating around Lake Erie and ones like it could become more common as the climate continues to change in a warming world. Nutrients in agricultural runoff is the biggest contributor to algae blooms in Lake Erie. What brings that… Read More
