Wildfires Tied to Drought, Heat & Topography, Not Beetles

Wildfires Tied to Drought, Heat & Topography, Not Beetles

Climate change-driven drought and higher temperatures are among the biggest factors, in addition to topography, influencing wildfire spread in the West, according to a new study, published in the Proceedings of the National Academy of Sciences.… Read More

Two Maps Show Countries’ Plans For CO2 Pledges

Two Maps Show Countries’ Plans For CO2 Pledges

International climate negotiations include every country from Afghanistan to Zimbabwe. And as the world gears up for Paris, climate watchers will be looking to see how (or if) each country plans to rise to the challenge of reducing the world’s carbon dioxide emissions. The next major climate talks are still nine months down the road, but commitment… Read More

Atlantic Circulation Weaker Than In Last Thousand Years

Atlantic Circulation Weaker Than In Last Thousand Years

Powerful Atlantic Ocean currents fuel Gulf streams, affect sea levels, warm cities in continental Europe and North America, and bring nutrients up from ocean depths that help sustain marine ecosystems and fisheries. But an avalanche of cold water from the melting Greenland ice sheet appears to be slowing the ocean circulation to levels not experie… Read More

Scientists Have Mixed Opinions on Flat CO2 Emissions

Scientists Have Mixed Opinions on Flat CO2 Emissions

Scientists have mixed opinions about whether stagnant global energy-related CO2 emissions are a trend following the International Energy Agency's announcement that flat emissions show that a growing economy and increasing CO2 emissions are no longer coupled.… Read More

Amazon Trees Removed Almost a Third Less Carbon

Amazon Trees Removed Almost a Third Less Carbon

The amount of carbon the Amazon’s remaining trees removed from the atmosphere fell by almost a third last decade, leading scientists to warn that manmade carbon emissions would need to be cut more deeply to tackle climate change. Trees in untouched areas of the forest have been dying off across the basin at an increasing rate, found the study, publ… Read More

Deforestation Slowing, But Forests Are Breaking Down

Deforestation Slowing, But Forests Are Breaking Down

The amount of climate pollution being produced every year by the felling of forests is falling worldwide, but benefits of the heartening decline are being eroded by the worsening conditions of the forests still left standing. The losses of entire stretches of forests, combined with losses of individual trees from forests that remain, pumped an ave… Read More

‘Green’ Diesel Fuel Use Plummets in U.S.

After briefly being a hit in the U.S., the use of green diesel in the U.S. is declining as imports from overseas plummet, at least for now, according to a new report from the U.S. Energy Information Administration.… Read More

Index Shows Oil’s Climate Impacts Vary Widely

Index Shows Oil’s Climate Impacts Vary Widely

Crude oils produced in different parts of the world involve different levels of greenhouse gas emissions. There is an 80 percent difference in emissions between the cleanest oil and the dirtiest oil, according to the Carnegie Endowment's Oil-Climate Index.… Read More
