CO2 on Path to Cross 400 ppm Threshold for a Month

CO2 on Path to Cross 400 ppm Threshold for a Month

Last year, atmospheric carbon dioxide crossed 400 parts per million for the first time in human history. However, it didn’t cross that threshold until mid-May. This year’s first 400 ppm reading came a full two months earlier this past week and the seeming inexorable upward march is likely to race past another milestone next month. “We’re already s… Read More

New Ozone-Destroying Gases Found in the Atmosphere

Dozens of mysterious ozone-destroying chemicals may be undermining the recovery of the giant ozone hole over Antarctica, researchers have revealed. The chemicals, which are also extremely potent greenhouse gases, may be leaking from industrial plants or being used illegally, contravening the Montreal protocol which began banning the ozone destroye… Read More

Let it Rain: NASA Satellites Show Slice of Global Precip

Lacy ribbons of precipitation stretch across the planet in a new animation from NASA showing how widespread and yet ephemeral rain can be. A series of satellites known as the Tropical Rainfall Measuring Mission (TRMM) measure heavy to moderate rain over tropical and subtropical regions every day. From those satellite measurements taken every 3 hour… Read More

What Winds From 20 Massive Winter Storms Look Like

Think you had a rough winter? Just be thankful you don’t live on the coast of the North Sea. The National Oceanic and Atmospheric Administration has whipped up a map of wind anomalies from January-February. During that period, a remarkable 20 storms with hurricane-force winds (classified as winds in excess of 74 mph) formed in the region. The mar… Read More

Social Cost of Carbon Greatly Underestimated: Report

Social Cost of Carbon Greatly Underestimated: Report

Carbon dioxide emissions are causing the climate to change and those changes come with a real cost. The big questions are what’s the price tag for that “social” cost and when does it gets paid? According the a new report, current best estimates could actually be on the low end thanks to “unknown unknowns.” The most recent estimate for the cost of … Read More

Extreme Weather is a ‘Silver Lining’ for Climate Action

Extreme Weather is a ‘Silver Lining’ for Climate Action

Devastating extreme weather including recent flooding in England, Australia's hottest year on record and the U.S. being hit by a polar vortex have a "silver lining" of boosting climate change to the highest level of politics and reminding politicians that climate change is not a partisan issue, according to the UN's climate chief. Christiana Figue… Read More

Great Barrier Reef Faces ‘Irreversible’ Damage

Great Barrier Reef Faces ‘Irreversible’ Damage

The Great Barrier Reef will suffer “irreversible” damage by 2030 unless radical action is taken to lower carbon emissions, a stark new report has warned. Unless temperatures are kept below the internationally agreed limit of 2°C warming on pre-industrial levels, the reef will cease to be a coral-dominated ecosystem, the report warns. Coral bleachi… Read More
