A new study, which could help scientists model global change more accurately, finds that typhoons bury tons of carbon in the oceans

When typhoons and hurricanes sweep through mountainous areas, they cause more than human destruction. They also physically and chemically weather the mountains they pass, taking carbon with them and burying it in the oceans in the form of sediment. This in turn allows the planet to cool. While scientists have long predicted that extreme storms cause such effects, only recently have they been able to measure just how carbon much storms take away: tons. Researchers from Ohio State University who measured carbon while a typhoon was passing through in full force in Taiwan—essential since sediment washes away very quickly after a storm—found that more than 400 tons of carbon was being swept away for each square mile of watershed during the storm. A single typhoon in Taiwan, they determined, buries as much carbon in the ocean as all the rains combined in the country for that year.

Although the findings are preliminary and the carbon buried by storms won't alleviate global warming, the data could still be useful to scientists as a benchmark to calculate the Earth's carbon "budget," which is how much carbon is added and removed from the atmosphere overall. Right now, those numbers could be way off if accurate carbon data from storms are not considered.

It's about time someone reports on the science of the earth taking care of its self. Polution, fires floods have been happening through out time and only recently with the advent of "global warming" (hasn't the earth been warming ever since the last ice age) is it all gloom and doom. There are impacts made by humans but is the planet really that fragile?

anwar, it kinda is. and yeah, i wouldnt be suprised that the earth in someway can take care of itself. but really, who does it have to take care of? its not out to impress anyone. nor does it need to impress anyone. this is just a coincidence. also, you dont get how fast global warming is. the 2nd fastest warming was millions of years ago before humans. it was when methane stored in ice at the bottom of the ocean bubbled out like seltzer. tghis happened over 10,000 years and the climate rose 10 degrees. now today with humans killing half of the tree on the planet the rates will be even faster because carbon dioxide cant be taken out of the air fast enough and its rose around 3 degrees(im nto sure though) over the past 200 or so years. thats alot faster.

The biggest spieces affected is man and if we go; someone
or something else will take our place.
Trust in the force

anwar-
it might be that "pollution" has been around for a few thousand years, but it's never really been a serious problem until the last few hundred. there has been a SIGNIFICANT increase. and we keep finding new ways to pollute (shooting it into space). so it isnt like we've really seen the effects of the damage yet. we cant keep this up. fortunately the people not ignorant to this are many and hopefully we'll start acting on this serious issue. so yeah, the earth isnt fragile, but it can only take so much!

It is starting to seem to me that the relationship between man and the Earth is a lot more complex than climate models typically imagine. For instance, on the same page that I found this little article appeared another one about "leaded" clouds promoting global cooling. So does sulfur dioxide, which used to spew voluminously from coal power plants.

If you also recall, gasoline used to be highly leaded and coal plants have been scrubbed so that they smell better. But both of these changes were parallel to the rapid increase in global warming which lasted from maybe 1950 to 1998. It is at least possible that it was man who caused this warming by cleaning up his act and that the steady increase in our carbon dioxide output simply is too wimpy a climate factor to overpower any other factor, such as sunspot activity, other natural variation, or even other human climate inputs.

I am convinced now that neither Greenland nor Antarctica ice sheets are melting due to atmospheric temperatures. Probably they are growing. The shore ice gets undercut by warmer ocean currents and breaks off. That is ALL that is going on. The study by Steig et all recently which argued that Antarctica is warming slightly in the last 50 years basically made up data to plug in empty data fields. When you have to advance arguments to justify "extrapolating" numbers in order to get "averages" that you like, you aren't working with real temperature readings anymore, you are working with arguments.

The last, best evidence of continued global warming in the 21st century is the summer Arctic ice meltback. This phenomenon, however, is highly susceptible to another human input, and that is dust put into the atmosphere in China through industrialization and in Mongolia due to over-grazing and drought. Don't forget the Gobi desert, either.
Dust falling on snow or ice increases the solar melting of same. The Arctic summer meltback may also have been due to ocean current changes bringing up warmer Pacific water.

So, there are a lot of reasons that this summer's Arctic ocean ice cover meltback will regress toward the pre-2006 mean. Also that global climate generally will continue to cool in this century, perhaps a tiny bit more so if humans really do manage to cut Carbon Dioxide output.
