The fires were costly for the rest
of the planet, too:
At their peak, the blazes belched more climate -

Atmospheric dust may have a powerful effect on climate, absorbing sunlight and
warming the
atmosphere at some altitudes while shading and cooling underlying layers
of air.
During the Eocene, the concentration
of carbon dioxide in the
atmosphere was more than 560 parts per million,
at least twice preindustrial levels, and the epoch kicked off with a global average temperature more than 8 degrees Celsius — about 14 degrees Fahrenheit —
warmer than today, gradually cooling over the next 22 million years.
«Although most
of the macrophyte carbon is released back to the
atmosphere in the same form that it is assimilated, carbon dioxide, some
of it is actually exported to the ocean as dissolved carbon or released to the
atmosphere as methane, a gas that has a
warming potential 20 times larger than carbon dioxide,» said John Melack, a professor
at the University
of California, Santa Barbara.
Several new studies
of the satellite and balloon data have now largely resolved this discrepancy — with consistent
warming found
at the surface and in the
atmosphere.
That collision between very

The work by Mark Jacobson, director
of Stanford University's
Atmosphere / Energy program and a fellow
at the university's Woods Institute, argues that cutting emissions
of black carbon may be the fastest method to limit the ongoing loss
of ice in the Arctic, which is
warming twice as fast as the global average.
Instead
of piping in natural CO2, it will use the greenhouse gas captured
at a coal - fired power plant just completed nearly 100 miles north
of here and send it down into the reservoir, pushing oil out and leaving the greenhouse gas deep below, safely locked away from the
atmosphere, so it does not add to global
warming.
Research
at the Rodale Institute found that «organic farming helps combat global
warming by capturing atmospheric carbon dioxide and incorporating it into the soil, whereas conventional farming exacerbates the greenhouse effect by producing a net release
of carbon into the
atmosphere.»
It may seem surprising to people, but you can look
at something like Mars, which has a very thin
atmosphere, and you can look
at something like Venus which we tend to think
of as sort
of having this rather heavy, clouded
atmosphere, which [is] hellishly
warm because
of runaway greenhouse effect, and on both
of those planets you are seeing this phenomenon
of the
atmosphere leaking away, is actually what directly has led to those very different outcomes for those planets; the specifics
of what happened as the
atmosphere started to go in each case [made] all the difference.
The rate
at which carbon emissions
warmed Earth's climate almost 56 million years ago resembles modern, human - caused global
warming much more than previously believed, but involved two pulses
of carbon to the
atmosphere, University
of Utah researchers and their colleagues found.
«As the climate gets
warmer, the thawing permafrost not only enables the release
of more greenhouse gases to the
atmosphere, but our study shows that it also allows much more mineral - laden and nutrient - rich water to be transported to rivers, groundwater and eventually the Arctic Ocean,» explained Ryan Toohey, a researcher
at the Interior Department's Alaska Climate Science Center in Anchorage and the lead author
of the study.
The climate is
warming in the arctic
at twice the rate
of the rest
of the globe creating a longer growing season and increased plant growth, which captures atmospheric carbon, and thawing permafrost, which releases carbon into the

At the same time, carbon soot and other compounds absorb heat,
warming the lower parts
of the
atmosphere.
And achieving any stabilization target — whether 2 degrees C
of warming or 450 ppm or 1,000 gigatons
of carbon added to the
atmosphere by human activity — will require
at least an 80 percent cut in emissions from peak levels by the end
of this century and, ultimately, zero emissions over the long term.
Year - round ice - free conditions across the surface
of the Arctic Ocean could explain why Earth was substantially
warmer during the Pliocene Epoch than it is today, despite similar concentrations
of carbon dioxide in the
atmosphere, according to new research carried out
at the University
of Colorado Boulder.
It represents the
warming at the earth's surface that is expected after the concentration
of CO2 in the
atmosphere doubles and the climate subsequently stabilizes (reaches equilibrium).
Carbon dioxide gets more press, but methane is the more powerful agent
of global
warming, 21 times more effective than carbon dioxide
at trapping heat in the
atmosphere.
At the same time, new studies
of climate sensitivity — the amount
of warming expected for a doubling
of carbon dioxide levels from 0.03 to 0.06 percent in the
atmosphere — have suggested that most models are too sensitive.
Although there is much less
of it in the air, it is 33 times more effective than carbon dioxide
at trapping heat in the
atmosphere and adding to greenhouse
warming.
That would translate to steadily rising temperatures as carbon pollution continues to accumulate in the
atmosphere (see red curve below), and fail to reach the goal
of holding
warming to 2 °C (blue curve
at bottom).
Using 19 climate models, a team
of researchers led by Professor Minghua Zhang
of the School
of Marine and Atmospheric Sciences
at Stony Brook University, discovered persistent dry and
warm biases
of simulated climate over the region
of the Southern Great Plain in the central U.S. that was caused by poor modeling
of atmospheric convective systems — the vertical transport
of heat and moisture in the
atmosphere.
According to the accepted view, the formation
of the Earth released vast amounts
of water vapour and carbon dioxide, which formed a thick
atmosphere and caused strong greenhouse
warming at a time when the Sun was 15 to 20 per cent fainter than today.
One thing is already clear: A
warmer global
atmosphere currently holds about 3 to 5 percent more water vapor than it did
at the beginning
of the 20th century, and that can contribute to heavier precipitation.
Normally, titanium oxide in the
atmospheres of hot Jupiters absorbs light and reradiates it as heat, making the
atmosphere grow
warmer at higher altitudes.
The
warm Atlantic water was saltier, and therefore heavier and subducted
at depth and reached to the bottom, actually heating up beneath a lid
of ice and melt water, that prevented the release
of heat to the
atmosphere.
But instead
of just looking
at which regions have
warmed the most, they also examined the height in the
atmosphere where the
warming took place.
Also
at the AGU meeting, Yasunari's co-author and Goddard colleague William Lau presented the results
of a separate study today suggesting that soot heating the
atmosphere over India could accelerate the glacier - melting effects
of the
warm currents that rise up to the Himalayan chain, in a «heat pump» effect.
The
atmosphere in the polar regions has
warmed at about twice the average rate
of global
warming with Arctic coasts experiencing a rise in the occurrence
of storm surges.
He makes the point, for example, that when you are looking [talking] about global
warming, when you're looking
at the climate [and] the
atmosphere, you are talking about in effect a good that belongs to all
of us.
«The amount
of visible radiation entering the lower
atmosphere was increasing, which implies
warming at the surface,» says atmospheric physicist Joanna Haigh
of Imperial College London, who led the research, published in Nature on October 7.
Then in 2003, William Ruddiman, a palaeoclimatologist
at the University
of Virginia, suggested the advent
of agriculture 8000 years ago ramped up levels
of the greenhouse gas methane in the
atmosphere,
warming the world by about 0.8 °C.
For instance, if nothing is done to reduce the amount
of heat - trapping gasses, such as carbon dioxide, in the
atmosphere, Earth could be 5 to 15 degrees Fahrenheit (3 to 8 degrees Celsius)
warmer by the end
of century, said Sivan Kartha, a senior scientist
at the Stockholm Environment Institute.
At the outset
of her work, Jansson suspected that
warming trends might activate bacterial processes that break down stored carbon, releasing it into the
atmosphere and fueling climate change.
According to Dr. Kevin Trenberth
at NCAR in Boulder, Colo., an increase in water vapor floating overhead, triggered by
warming of the
atmosphere and oceans, is already loading the dice.
The observed fact that temperatures increases slower over the oceans than over land demonstrates that the large heat capacity
of the ocean tries to hold back the
warming of the air over the ocean and produces a delay
at the surface but nevertheless the
atmosphere responds quit rapidly to increasing greenhouse gases.
The Nature article comes as climate scientists published what they said today was the «best ever» collection
of evidence for global
warming, including temperature over land,
at sea and in the higher
atmosphere, along with records
of humidity, sea - level rise, and melting ice.
In addition to these multiple lines
of empirical evidence which contradict the GCR
warming theory, the galactic cosmic ray theory can not easily explain the cooling
of the upper
atmosphere, greater
warming at night, or greater
warming at higher latitudes.
Roy Spencer, best known for his satellite work arguing against
warming of the
atmosphere (which turns out to have been an artifact
of a combination
of algebraic and sign errors), criticizes Gore for pointing out that recent warmth appears to be anomalous in
at least the past 1000 years.
For example, if global
warming were due to increased solar output, we would expect to see all layers
of the
atmosphere warm, and more
warming during the day when the surface is bombarded with solar radiation than
at night.
Carbon dioxide emitted
at the start
of the industrial revolution is still
warming the
atmosphere today, which is why scientists take into account historical emissions as well as present day ones to work out a country's contribution to climate change.
As mentioned in the introduction, the satellites which measure incoming and outgoing radiation
at the top
of Earth's
atmosphere (TOA) can not measure the small planetary energy imbalance brought about by global
warming.
