Global Greening is Happening Faster Than Climate Change

REJOICE IN THE LUSH GLOBAL GREENING CO2 is plant food. The greening of the earth means more food for animals and greater crop yields for humans. Why is no one talking about it?

Amid all the talk of an imminent planetary catastrophe caused by emissions of carbon dioxide, another fact is often ignored: global greening is happening faster than climate change. The amount of vegetation growing on the earth has been increasing every year for at least 30 years. The evidence comes from the growth rate of plants and from satellite data.

Sources and Sinks

For the entire history of our species, humans have lived on a planet capped by a chunk of ice at each pole. But Earth has been ice-free for about 75 percent of the time since complex life first appeared. This variation in background climate, between partly glaciated and ice-free, has puzzled geologists for decades.

Now a team of scientists led by UC Santa Barbara’s Francis Macdonald has published a study suggesting that tectonic activity may be the culprit. They found that long-term trends in Earth’s climate are set by the presence or absence of collisions between volcanic arcs and continents in the tropics. The results appear in the journal Science.

“There’ve been a few hypotheses but no agreements as to why we have warmer or colder climates on these very long timescales,” said Macdonald, a professor in the Department of Earth Science.

Earth Is Sucking Down Way More Water Than We Thought, And No One’s Sure Where It’s Going

Re-Blogged From Science Alert

Slow-motion collisions of tectonic plates under the ocean drag about three times more water down into the deep Earth than previously believed, according to a seismic study that spans the Mariana Trench.

The observations from the deepest ocean trench in the world have important implications for the global water cycle, researchers say.

On to Paris: To keep pledges made at meetings (multiple Conference of Parties (COP)) of the UN Framework Convention on Climate Change (UNFCCC), an international treaty agreed to in 1992 by the first president Bush and which went into force in 1994, 33 out of 195 countries submitted their pledges to reduce greenhouse gas emissions (particularly carbon dioxide (CO2)). These are to be agreed upon at the December COP in Paris. These pledges are called Intended National Determined Contribution (INDC). The countries that submitted pledges by March 31 included those in the European Union, the US, Russia, and Mexico.
