CO2 Levels Have Crossed 400 PPM Threshold Far Earlier This Year

CO2 Levels Have Crossed 400 PPM Threshold Far Earlier This Year

written by Yale Environment 360

Concentrations of carbon dioxide in the atmosphere have reached the 400 parts per million threshold two months earlier this year than last, an indication that the planet will soon experience the 400 ppm level year-round, according to scientists from the Scripps Institute of Oceanography.

Last year was the first time in hundreds of thousands of years that the 400 ppm threshold was crossed. Scripps scientists expect CO2 levels to hover around 400 ppm for the next two months, when the Northern Hemisphere spring will go into full bloom and plants will suck CO2 from the atmosphere until going dormant in the fall.

“It’s just a matter of time before it stays over 400 forever,” said Ralph Keeling, who took over the CO2 monitoring program from his father, Charles David Keeling, who started it in 1958. Since then, atmospheric CO2 levels have risen steadily from 313 ppm as the world continues to burn fossil fuels. Scientists estimate it’s been 800,000 to 15 million years since the planet has seen concentrations this high.

Setting an Energy Policy

written by Walter Wang

As I’ve written here once or twice before, it’s unconscionable that the U.S. doesn’t have an energy policy. What’s the matter with picking a direction and heading that way?

Apparently, the Japanese province of Fukushima has done exactly that, prompted, I presume, by the

IPCC Scientists Warn of Upper Limit on CO2 Emissions

written by Yale Environment 360

Saying it is 95 percent certain that humans have caused most of the global warming of the last half-century, scientists with the Intergovernmental Panel on Climate Change (IPCC) warned today that the world can afford to burn about 1 trillion more tons of carbon before facing extreme climate change.

New Insight on How Tropical Forests Capture Carbon

written by Walter Wang

Tropical forests are important globally in removing carbon from the atmosphere. It has been assumed that the tress were the mechanism that made this work. New research from Princeton University has shed insight on the importance of bacteria that co-exist with the trees have in absorbing atmospheric carbon.

Estimating the Externalities of Fossil Fuels Isn’t an Easy Job

written by Walter Wang

I sympathize with those tasked with putting a precise dollar figure on the externalities of fossil fuels. Sure we know there are costs to society in terms of lung damage and long-term environmental damage, but what are they?

The story of the petcoke piles in modern-day Detroit is a case in point.

Conventional Hybrids Better for Climate Than EV’s in Most U.S. States

written by Yale Environment 360

Conventional gas-powered hybrid vehicles are still better for the climate than all-electric cars in most U.S. states, in part because these states still rely heavily on fossil fuels to produce electricity, according to a new report.

In 39 states, high-efficiency hybrids, such as
