Climate changes making planet greener
CNN ^ | Thursday, June 5, 2003 | Richard Stenger

(CNN) -- The Earth has become significantly greener over the past two decades, the result of climate changes that have furnished plants with more heat, light, water and carbon dioxide, according to a new Science magazine report.

The overall plant bulk went up about 6 percent over much of the planet, with spikes in the tropics and high latitudes of the Northern Hemisphere accounting for 80 percent of the gains, researchers said.

The years since 1980 included two of the warmest decades on record, producing changes that have boosted growth ingredients in regions where they might otherwise have been scarce.

A 9.3 percent increase in the greenhouse gas carbon dioxide, a de facto fertilizer, was significant, but not enough to produce by itself the kind of vegetative growth the study found.

Not everywhere has become more vegetated. About 7 percent of the studied landmasses experienced drops in plant productivity.

"The biggest winners [becoming more green] seem to be India, Brazil and Canada," said lead author Ramakrishna Nemani. "Losers are parts of Mexico and northern Siberia [drying and cooling, respectively]."

The Amazon rain forest alone was responsible for more than 40 percent of the plant growth, mostly due to reduced cloud cover that let in more sunshine.

"The most surprising result is that of the Amazon," said Nemani, a forestry professor at the University of Montana in Missoula.

The South American rain forest has suffered from deforestation on the edges in recent decades, but the interior sections have grown vigorously, he said.

"Much of this increased growth has been attributed to carbon dioxide," Nemani said. "What we found is that changes in cloud cover may be a better explanation."

The study, funded by NASA and the Department of Energy, includes decades worth of satellite and ground data, which the research team studied for nearly a year and a half to determine plant productivity.

"Productivity [refers to] how much carbon ends up stored in the biomass -- roots, trunks and leaves -- of plants after they tally up carbon gains through photosynthesis and carbon losses through respiration [the plant version of an exhalation]," said Rebecca Lindsey, a spokeswoman with NASA's Earth Observatory in Greenbelt, Maryland.

Report co-author Charles Keeling, a carbon cycle specialist at the Scripps Institution of Oceanography in La Jolla, California, said the ultimate cause could be short-term climate patterns or long-term global climate shifts.

Whether humans have contributed much to the greening trend remains unknown, but co-author Ranga Myneni cautions that we should hold off on congratulating ourselves on our green thumbs.

"[Plant] productivity may have increased 6 percent in the last 18 years, but human population has increased by over 35 percent over that same time," the Boston University geographer said.

"These ... changes have not improved global habitability in any significant way."

You know, they're called GREEN houses for a reason. Does this mean that we can start referring to environmentalists as anti-rainforest?

This is my first time posting an article, please be gentle.

Well isn't that a bitch, and here I thought that all the global warming was cooking us alive.

Turns out that it (if there really IS global warming) is pumping more oxygen into the air so I can breathe better.

Keep those cars running folks.

Going back what? 200 years? And the planet is how old? And it has been how long since the last Ice Age?

Talk about cherry-picking your data.

The three ingredients necessary for life as we know it are water, heat, and carbon.

Global warming increases all three.

If it were true that humans were causing it, animals should be so full of gratitude, they should volunteer to let us eat them. (Hell, we're going to do it anyway.)

Reality check: for the past 150 years, we have been comming out of a little ice age. Temperatures are still lower than they were from 800-1300.

No doubt Global warming has some benefits. What we don't want though is a hole in the Ozone layer. I've been to the south island of New Zealand and the atmosphere is so thin there that the light is like daggers in your eyes. CO2 yes, CFS's no.

Excellent post.

I think I'll barbecue some dead cow in celebration of the forthcoming food glut. Aussie-ally wine ought to go well with that.

Actually, aren't we STILL in an ice age? Large portions of the planet are ice-bound year round.

What gets me is that if this planet swerved off its orbit by some tiny fraction of a percent, we would either cook (if closer to sun) or freeze (if further away). What's the government going to do about that?

It's CFC's, not CFS's; in any case, your eyes can't record the difference in ozone levels and UVA or UVB transmitted through the layer.

Paging Al Gore...

I can see how this would upset the environmentalists. (/sarcasm)

Or is this more proof that the so-called environmentalists couldn't care less about the environment, they just want to kill industry and capitalist economy.

Great a few more degrees and we will enter the dark ages.

Nope. In the last great ice age, the ice sheets carved out the Great Lakes and reached Long Island.

What gets me is that if this planet swerved off its orbit by some tiny fraction of a percent, we would either cook (if closer to sun) or freeze (if further away). What's the government going to do about that?
Nothing.

if by that you mean grapevines growing wild in Ireland and Nova Scotia, that would be fine.

it's always nice to read a "pro-life" post. Maybe we need to expand the abortion industry to include plant life.

"if by that (we will enter the dark ages) you mean grapevines growing wild in Ireland and Nova Scotia, that would be fine."

By that, I meant a period compatible with 800-1200 where man is in continual war (perhaps temperature induced anger) and the Muslims attempt to destroy or capture any civilization except there own. (Seems like that has already started). And mankind doesn't advance because Christians are too consumed trying to contain the Muslim threat (Seems like that has already started too.)

Grapevines growing wild does sound sort of nice. Maybe I should move north.

It's already happening in Europe. And civilization seems to have shifted to lower latitudes and the subtropics. Recall the guilded societies of China, Mali, Arabia, India, and Mesoamerica. Look at today's progress in southern Africa, Latin America, India, Israel, the Philippines, and--most of all, as always--the United States of America. Europe, along with a few dictatorial regimes, are regressing.

You have it backwards.
the Warm period of the 800-1300 say civilization move north with Northern Europe flourishing.
