It's on the BBC, it must be true

LONDON, Jan 13 (Reuters) - Cutting down on fossil fuel pollution could accelerate global warming and help turn parts of Europe into desert by 2100, according to research to be aired on British television on Thursday. "Global Dimming", a BBC Horizon documentary, will describe research suggesting fossil fuel by-products like sulphur dioxide particles reflect the sun's rays, "dimming" temperatures and almost cancelling out the greenhouse effect.

The researchers say cutting down on the burning of coal and oil, one of the main goals of international environmental agreements, will drastically heat rather than cool climate.

"When the cooling affect goes away -- and it must do because particles like sulphur dioxide are damaging to humans -- global warming will be much stronger," climate change scientist Dr Peter Cox told Reuters on Wednesday.

Temperatures could increase in the worst case by up to 10 degrees by the end of the century, the researchers said -- much more than current estimates.

Scientists differ as to whether global warming is caused by man-made emissions of carbon dioxide and other "greenhouse" gases, by natural climate cycles or if it exists at all.

Take away fossil fuel by-products like sulphur dioxide without tackling greenhouse gas emissions, and the extra heat will speed warming, irreversibly melting ice sheets and rendering rain forests unsustainable within decades, Dr Cox said.

"The climate will warm more in the future but the ability of the land to store carbon dioxide will be compromised," he said, adding that warmer soil was less able to hold the greenhouse gas.

erm...you don't believe in Global Warming?

I thought you would've looked at the facts Gonz

I have. It's cyclical. We didn't do shit to start it or enhance it.
 
Yup, I have to give kudos to global warming, my city is no longer under 50-meters of ice.

Gonz is right I do believe. ...thats the facts jack
 
That the climate undergoes a degree of cycling seems fairly certain based on evidence such as ice cores, etc. However, that doesn't preclude that the species Homo sapiens doesn't/hasn't contribute(d) to this cycle in some way. :shrug:

Psst...the Earth's orbit has a 10,000 year eliptical cycle. It's been proven by those same ice-cores, etc., that you spoke of. We're due for a hot spell. Blaming humans is just a ridiculous assumption. Active volcanoes are responsible for pollution as well...but you're not trying to shut those off. :D

Yes us wee lil humans will be the end of the earth.
At the current rate of CO2 production earth will soon
have the same surface temperature as Venus.

Ya know noonday highs that will melt lead?

How do you explain the thining ozone layer then?

Is that a natural phenomenon?

Volcanic activity, forest fires (which are also naturally occuring), coupled with the eccentric orbit our planet has. Remember...every 10,000 years we have either an ice age, or a hot spell because our orbit spirals in towards the sun, picks up a little speed due to gravitational forces, and spirals out again. This global warming phenomenon has been building up for at least 5,000 years...and we only started measuring such changes in the past 100 years. Scientists became concerned by this way back in the early 1970's, but yet the temperature climb is slow and steady. They looked for a scapegoat, and blamed mankind. Nevermind that Mt. St. Helens put out more pollution in one eruption than mankind did in 10 years. Don't look at the fact that Mt. Pinatubo put out more pollution in one blast than mankind did in 25 years, and overlook the fact that active volcanoes alone are constantly venting greenhouse gases. Couple that with active supervolcanoes, such as Yellowstone Park, which also constantly release 'greenhouse' gases, and you'll get a wider picture. Yes...we pollute, but to blame the warming on mankind alone is extremely short-sighted, and shows a distinct lack of study.

Okay... :ashamed:

You can explain it...

*CB wanders away mumbling about know it alls*

:p I just tend to read further into an issue than most. The first time I heard the term 'Global Warming' was on the movie Soylent Green. I didn't give it much thought until about 20 years later, when everybody started making a fuss over it. :shrug: As human beings, we tend to have an overblown ego about how much we actually do...

Or certain "reputable" Scientific journal / article writers are "funded" by large corporate companies that depend upon the burning of fossil fuels for business...
 
You left out the effects of continental drift on the ocean conveyor, and how less arctic ice means more algae, which absorb more co2, which reduce greenhouse gas. And feed more plankton, which feeds more whales. Whales that fart, and emit methane (another greenhouse gas).


Everyone blames huge herds of cows for methane emissions. I wonder if anyone ever calculated the methane emitted from a Brontosaurus.
 
Fossil fules might make cities smell bad and give city kids asthma, but that's micro-polution. On a macro scale we the people are pretty insignificant. We are also full of ourselves if we think we can destroy the earth.
