NASA’s TIMED mission, short for Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics, has confirmed a surprisingly fast carbon dioxide increase in Earth’s upper atmosphere, raising questions about how different layers of the atmosphere are interconnected. Even more curious—though climate mod...

Despite continuing concern about the fate of iconic rainforests, new research shows that the world’s forests have stored away an extra 4 billion tonnes of carbon in the last dozen years and the total amount of woodland has increased worldwide since 2003. The encouraging news comes from Australian s...

Peru, the host for December’s UN climate change summit, stores nearly seven billion metric tons of carbon stocks, mostly in its Amazon rainforest. That’s more than US annual carbon emissions for 2013 which were calculated at 5.38 billion tons, the new research by the Carnegie Institute for...

As this week's viral photo of 35,000 walruses crammed on an Alaskan shore reminds us, the climate crisis is still very much a thing. For those who missed it, a lack of Arctic ice evidently forced the poor creatures to huddle together on a narrow piece of land out of desperation -- normally, they're ...

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...

Reducing deforestation in the tropics would significantly cut the amount of carbon dioxide emitted into the atmosphere – by as much as one-fifth – research shows. In the first study of its kind, scientists have calculated the amount of carbon absorbed by the world's tropical forests and t...

A NOAA-led research team has found the first evidence that acidity of continental shelf waters off the West Coast is dissolving the shells of tiny free-swimming marine snails, called pteropods, which provide food for pink salmon, mackerel and herring, according to a new paper published in Proce...

The nutritional quality of food crops may be at risk if climate change intensifies, according to a recent study. In a wheat field test, scientists found that elevated carbon dioxide may inhibit plants' assimilation of nitrate into proteins. The findings were published online in the journal Nature C...

Change is taking place in the tropical Pacific Ocean, where NOAA (National Oceanic and Atmospheric Administration) researchers have found that carbon dioxide (CO2) concentrations have increased as much as 65 percent faster than atmospheric CO2 since 1998. Rising CO2 concentrations of this magnitude ...

The past four days have been a frozen hell for an estimated 186 million people across parts of Canada and all 50 states in the US, as freezing air called the polar vortex swirled down from melting polar ice caps. There were 21 deaths attributed to weather-related incidents, with transport...

A new study on an array of marine animals shows that they all will suffer in different ways in the acidified oceans of coming decades. That means rising carbon dioxide levels will trigger some profound reshuffling of life in the seas as some species are more hurt than others. Because some of the ca...

By early August, scientists will have pumped 1,000 tonnes of pure carbon dioxide into porous rock far below the northwestern United States. The goal is to find a permanent home for the carbon dioxide generated by human activities. Researchers at the US Department of Energy’s Pacific Northwest Natio...

Carbon dioxide in our air recently hit 400 parts per million. Since you asked, yes, that’s a lot. Perhaps this a good time to reflect on what we as individuals can do to stem the flow of harmful gasses into our atmosphere. Climate change and carbon dioxide impacts are difficult to comprehend and mak...
