Climate change happening, worst yet to come

Human-caused global warming is here — visible in the air, water and melting ice — and is destined to get much worse in the future, an authoritative global scientific report will warn next week.
"The smoking gun is definitely lying on the table as we speak," said top U.S. climate scientist Jerry Mahlman, who reviewed all 1,600 pages of the first segment of a giant four-part report. "The evidence Â… is compelling."
The first phase of the Intergovernmental Panel on Climate Change is being released in Paris next week.
This segment, written by more than 600 scientists and reviewed by another 600 experts and edited by bureaucrats from 154 countries, includes "a significantly expanded discussion of observation on the climate," said co-chair Susan Solomon a senior scientist for the U.S. National Oceanic and Atmospheric Administration.
She and other scientists held a telephone briefing on the report Monday.
'Explosion of new data'
That report will feature an "explosion of new data" on observations of current global warming, Solomon said.
Solomon and others wouldn't go into specifics about what the report says. They said that the 12-page summary for policy-makers will be edited in secret word-by-word by governments officials for several days next week and released to the public on Feb. 2. The rest of that first report from scientists will come out months later. The full report will be issued in four phases over the year, as was the case with the last IPCC report, issued in 2001.
Global warming is "happening now, it's very obvious," said Mahlman, a former director of NOAA's Geophysical Fluid Dynamics Lab who lives in Boulder, Colo. "When you look at the temperature of the Earth, it's pretty much a no-brainer."
Look for an "iconic statement" — a simple but strong and unequivocal summary — on how global warming is now occurring, said one of the authors, Kevin Trenberth, director of climate analysis at the National Center for Atmospheric Research, also in Boulder.
The February report will have "much stronger evidence now of human actions on the change in climate that's taken place," Rajendra Pachauri said in an interview in November. Pachauri, an Indian climatologist, is the head of the international climate change panel.
More evidence of warming
An early version of the ever-changing draft report said "observations of coherent warming in the global atmosphere, in the ocean, and in snow and ice now provide stronger joint evidence of warming."
And the early draft adds: "An increasing body of evidence suggests a discernible human influence on other aspects of climate including sea ice, heat waves and other extremes, circulation, storm tracks and precipitation."
The world's global average temperature has risen about 0.66 C from 1901 to 2005. The two warmest years on record for the world were 2005 and 1998. Last year was the hottest year on record for the United States.
The report will draw on already published peer-review science. Some recent scientific studies show that temperatures are the hottest in thousands of years, especially during the last 30 years; ice sheets in Greenland in the past couple years have shown a dramatic melting; and sea levels are rising and doing so at a faster rate in the past decade.
Effects on health, species, food
Also, the second part of the international climate panel's report — to be released in April — will for the first time feature a blockbuster chapter on how global warming is already changing health, species, engineering and food production, said NASA scientist Cynthia Rosenzweig, author of that chapter.
As confident as scientists are about the global warming effects that they've already documented, they are as gloomy about the future and even hotter weather and higher sea level rises. Predictions for the future of global warming in the report are based on 19 computer models, about twice as many as in the past, Solomon said.
In 2001, the panel said the world's average temperature would increase somewhere between about 1.4 C and 5.8 C and the sea level would rise between 10 and 89 centimetres by the year 2100. The 2007 report will likely have a smaller range of numbers for both predictions, Pachauri and other scientists said.
The future is bleak, scientists said.

But according to Chaos Theory, this is pretty normal. As time passes, the enviroment on the whole gets to become more chaotic. Thus potiential energy is converted to waste heat which raises temperature.

So many things to worry about. Global warming, $$ issues, war, asteriod crashing onto us, even Earth's magnetic field change also must worry.
Must worry so many thing, I might as well regret that I was borned onto Earth. -
That not the way it works.Originally posted by Herzog_Zwei:But according to Chaos Theory, this is pretty normal. As time passes, the enviroment on the whole gets to become more chaotic. Thus potiential energy is converted to waste heat which raises temperature.
Greenhouse gases Traps suns heat, instead of reflecting it back to space.
This is called GreenHouse Effect.
We are absorbing energy form the sun. -
haha,
i think the reason for human extinction will be greed. -
Maybe you borned in other planet also machiam same or maybe worst.Originally posted by Hogzilla:So many things to worry about. Global warming, $$ issues, war, asteriod crashing onto us, even Earth's magnetic field change also must worry.

Drive more!! drive more lah.

Imagine one day when there are only public transport and no private transport and whatsoever. Do you think it will be better?Originally posted by seow:Drive more!! drive more lah. -
I am certainly not too concerned about climate change. This is the politician's issue of the hour. They, and scientists involved both have an agenda; your votes and a salary respectively.
Looking at recorded history, there are many instances where global temperature has risn for no apparent reason. Yet we don't hear the romans (for eg) complaiing of global warming. -
Its a contribution of different sectors:Originally posted by seow:Drive more!! drive more lah.
1) transportation
2) power plants (fossil-fuel based)
3) construction industry
4) Others -
sooner or later sure come de lar

I dun wanna argue with you.Originally posted by scabstermooch:So putting forth just one side of a debate is, in your opinion, using your brain? Oh how the education system has failed us!
Go read around more, from recent local ST news and on internet.
The evidence is clear enough.
Wait for this friday report from Paris Climate Summit. -
Very old news, this crap has been drilled into us ever since primary school, and continues all the way till you stop studying.

Last disaster, and the world will come to an end !

Of course you don't. What the paris climate summit? That is like asking the Vegan Society if a vegetarian diet is ethical!Originally posted by EarthWalker:I dun wanna argue with you.

I'm afraid u are the vegeterian here.Originally posted by scabstermooch:Of course you don't. What the paris climate summit? That is like asking the Vegan Society if a vegetarian diet is ethical!
And I bet u didn't even read those links i provided.
Like u said it urself, go do ur own research before u come to any conclusion.
Else u are going to continue to live in ur own world forever.
