no no we still have problems with it lol. We have a long time to go before we consider everything ok

I remember when i was a young lass

Also...

You're a chick?

Pretty much.

i make one hella ugly girl but sure

Its snowing out again today and really bad. With hail too.

thats awesome i freaken love when it snows

Cosmic Rays Linked to Global Warming

Earth's recent warming trend might in part be due to a lack of starlight reaching our planet, a new study suggests. But other scientists are not so sure.


According to a theory proposed a decade ago, when a star explodes far away in the Milky Way, cosmic rays—high-speed atomic particles—go through the Earth’s atmosphere and produce ions and free electrons.


The released electrons act as catalysts and accelerate the formation of small clusters of sulfuric acid and water molecules, the building blocks of clouds. Therefore, cosmic rays would increase cloud cover on Earth, reflecting sunlight and keeping the planet relatively cool.


However, because the Sun’s magnetic field—which shields the Earth from these rays—doubled in intensity during the last century, there has been a reduction in cloudiness, a possible contributor to Earth’s warming.


Scientists at the Danish National Space Center mimicked chemistry of the lower atmosphere in a large reaction chamber. They created a mixture that contained gasses at realistic concentrations and used an ultraviolet lamp to act as the Sun.


Microscopic droplets, precursor to clouds, started floating in the air of the reaction chamber.


“We were amazed by the speed and efficiency with which the electrons do their work of creating the building blocks for the cloud condensation nuclei,” said team leader Henrik Svensmark, Director of the Center for Sun-Climate Research at the Danish National Space Center. “This is a completely new result within climate science.”


The results however, may not transfer to natural conditions outside the controlled laboratory environment.


“Studies that have evaluated the claims that global cloud cover is related to changes in cosmic rays find that if you re-examine this matter outside of the brief period which they used, the relationship falls apart,” said Raymond Bradley director of the Climate System Research Center at the University of Massachusetts. Bradley was not involved with the study.


The researchers agree that further study is needed to estimate the contribution of this mechanism to the recent warming of the Earth’s atmosphere and oceans.


This work does not mean that there is no human influence on climate, Svensmark told LiveScience. “But it might be necessary to revaluate the climate sensitivity to carbon dioxide.”


The study was detailed online this month in the Proceedings of the Royal Society A.

Actually the thread was a joke about global warming. I was just commenting on how it snowed last night and its could enough outside to keep the snow on the ground.

oh and mikey. Thats just your observation. Personally I feel like its been getting colder every year earlier and earlier. I cant remember the last time I saw snow in october.

lolOzone

for all the worrying these people do, fuck all has changed, if anything it seems to get COLDER every year.

Fuck global warming

the only new energy is almost entirely from the sun (and other stars), but energy in the human would get converted from chemical bonds in glucose, for instance, into new forms of energy like heat. so the human provides heat but not new energy.

Mars Melt Hints at Solar, Not Human, Cause for Warming, Scientist Says

Simultaneous warming on Earth and Mars suggests that our planet's recent climate changes have a natural—and not a human- induced—cause, according to one scientist's controversial theory.

Earth is currently experiencing rapid warming, which the vast majority of climate scientists says is due to humans pumping huge amounts of greenhouse gases into the atmosphere.

Mars, too, appears to be enjoying more mild and balmy temperatures.

In 2005 data from NASA's Mars Global Surveyor and Odyssey missions revealed that the carbon dioxide "ice caps" near Mars's south pole had been diminishing for three summers in a row.

Habibullo Abdussamatov, head of the St. Petersburg's Pulkovo Astronomical Observatory in Russia, says the Mars data is evidence that the current global warming on Earth is being caused by changes in the sun.

"The long-term increase in solar irradiance is heating both Earth and Mars," he said.

Abdussamatov believes that changes in the sun's heat output can account for almost all the climate changes we see on both planets.

Mars and Earth, for instance, have experienced periodic ice ages throughout their histories.

"Man-made greenhouse warming has made a small contribution to the warming seen on Earth in recent years, but it cannot compete with the increase in solar irradiance," Abdussamatov said.

By studying fluctuations in the warmth of the sun, Abdussamatov believes he can see a pattern that fits with the ups and downs in climate we see on Earth and Mars.

Abdussamatov's work, however, has not been well received by other climate scientists

I still keep my strong stance that Global Warming is not caused by Humans.
