Scientists discover an extra 5 million square kilometers of forest , just like that.
Scientists apparently can’t predict where forests are right now, but weather patterns one hundred years from now, no problem. It’s nearly 60 years since the first satellite was launched, and we are still figuring out basic stuff down here on the surface — like which bits are forest.
People are willing to set up a two trillion dollar global market to trade carbon, but their carbon models are so primitive that giant “oops” moments are still happening on a regular basis. In 2014 Indian accountants discovered they’d missed nearly half the carbon given off from their lakes and rivers. In 2015, an accounting error reduced China’s emissions by twice Australia’s output. Then later that year Yale guys found 2.6 trillion trees. Blame global warming. Forests are appearing everywhere. Trees are even growing on farms capturing 0.75 gigaton of carbon that no one noticed til last year.
Billions of dollars of carbon credits are winking in and out of existence with every scientific study. Bank that botany! A single paper could change national GDP.
How did they find 5 million square kilometers of trees? They stopped assuming that satellite photos would be enough and they did a field survey instead. They went there. (Let’s call this crazy idea “observation” — it might catch on.)
