NASA | Plant Productivity in a Warming World

The past decade is the warmest on record since instrumental measurements began in the 1880s. Previous research suggested that in the '80s and '90s, warmer global temperatures and higher levels of precipitation -- factors associated with climate change - were generally good for plant productivity. An updated analysis published this week in Science indicates that as temperatures have continued to rise, the benefits to plants are now overwhelmed by longer and more frequent droughts. High-resolution data from the Moderate Resolution Imaging Spectroradiometer, or MODIS, indicate a net decrease in NPP from 2000-2009, as compared to the previous two decades.

we need more smart people...

Please point the idiot climate change deniers to the NASA sites not the oil industry or republican sites.

[MrCooookie75]

Need MORE carbon DIOXIDE & less CHEMTRAILS...

John Searl had the answer.. FOOLS !!!

S.E.G. !!!

LOLOLOLOLOL you are so funny!

@flyingemu27 I thought permaculture was less productive than intensive farming.

@The0Burger0King Green energy by itself probably won't cut it. We need to use Nuclear energy as well.

@bearhuntaa The tipping point doesn't refer to a point where global warming will start to slow. It actually refers to a point where the globe will be warming so quickly that there will be very little we can do to stop it.

Think of it more like a car rolling down a hill. At the top plateau it's going slow, but as it picks up speed and goes further down the hill to the steep part - it gets faster and faster.

i've seen some charts that say you can't read charts.

@fuunguus Oh man i wish we had more skys on Earth.

How many skys do you have on your planet?
