Climate Change News Just Keeps Getting Worse and Worse


The World Meteorological Organization announced today that global levels of carbon dioxide reached their highest point ever in 2013. No surprise there. They also announced that the growth rate of CO2 reached its highest point ever. Brad Plumer provides the details:

There are two possible reasons why the amount of carbon-dioxide in the atmosphere is growing so rapidly. One is obvious: Humans  continue to emit more and more carbon-dioxide from power plants, cars, and factories each year.

But the other reason is a bit more surprising: According to the WMO, early data suggests that the world’s oceans and forests are now absorbing less of our extra carbon-dioxide than they used to — which means that more of it ends up in the atmosphere, where it traps heat and warms up the planet.

The amount of CO2 absorbed by the oceans is cyclical in the medium term, which probably helps explain why global temperatures periodically stabilize for a decade or so before resuming their usual upward march. But there’s also a long-term trend. Oceans can’t absorb CO2 indefinitely, and eventually they’ll reach their limit. As that happens, more and more CO2 will be trapped in the atmosphere, where it contributes to global warming. And unless we do something to rein in CO2 emissions, this will happen at the same time that humans are pumping ever more CO2 into the sky. More here.

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily crazy—Mother Jones' journalism is driven by one simple question: Will America will move closer to, or further from, justice and equity in the years to come?
