The sun heats the air in the greenhouse, and the hot air rises.
So we opted for a sombre burial in the Greenhouse, under the shade of the tallest of the mangroves, though in truth it meant a slightly watery grave after all, stuff seeping up through the muck to swallow the foot, bubbles of mud detaching and floating among us during our tiny, foot-size ritual observances.
While this week's number has garnered all sorts of attention, it is just a daily reading in the month when the chief greenhouse gas peaks in the Northern Hemisphere.
Officials here in California have decided to make this state the first in the nation to require reductions in emissions of the greenhouse gases that contribute to climate change.
That output is known to vary during the course of the 11-year sunspot cycle, as well as over the longer term, and although such changes have not been matched to temperature changes in the way that rises in the level of greenhouse gases have been, they may still be making a contribution.
Slowing and eventually halting the rise in greenhouse gas concentrations in the atmosphere would slow and eventually stop these changes.
Somewhere in the world--a state park in the U.S., most likely--that tree will soak up the carbon dioxide greenhouse gases produced in the operation of that PC.
The rich bear most of the responsibility for the greenhouse gases in the atmosphere.
Nonetheless, the idea that carbon dioxide spewed by the world's industries is causing more heat to be trapped in the atmosphere (the "greenhouse effect") has found wide acceptance.
"If it hadn't been for the increase in human-produced greenhouse gases, summer temperatures in the Arctic should have cooled gradually over the last century, " said Bette Otto-Bliesner, an NCAR scientist who participated in the study.
CNN: Warmest Arctic temperatures for 2,000 years, says new study
Based upon data from the paper, the cooling climate impact from the decrease in the average global cloud height more than offset the positive forcing from an increase in greenhouse gases from human activities in the last decade.
FORBES: An Unsettling Week For Global Warming's 'Settled Science'
And, what one single thing produces the most greenhouse gases in the United States?
The UNEP report follows on from a new analysis by the World Meteorological Organisation that says the amount of greenhouse gases in the atmosphere reached a record high in 2011.
Those costs, in the form of greenhouse gases, can no longer be ignored, McCain said.
Preemption, in the case of greenhouse gas regulation, is the only viable safeguard against unwarranted state interferences with the national economy.
The Commission says that illegal deforestation causes soil degradation, landslides, lost tax revenue, as well as an increase in the amount of greenhouse gases.
"Considering the rapid depletion of the world's oil reserve, the heightened global interest in addressing greenhouse gas emissions and the geopolitical complications of global oil supply and demand, " a report by the U.S. Department of Energy concluded.
Not only are they most affected but they have contributed the least to the build up of greenhouse gases in the atmosphere.
In the Northeast, the Regional Greenhouse Gas Initiative is already in place and is a mandatory program is to reduce carbon levels by 10 percent by 2018.
"I don't know who the top greenhouse gas emitter in the nation is, " Kruger says.
Indeed, it says that if shipping were a country, it would be the sixth-largest emitter of greenhouse gases in the world.
Climate sensitivity is a key parameter for estimating the long-term temperature increase expected from a doubling of the concentration of greenhouse gas emissions in the atmosphere.
Writing in the journal Nature in 2007, researchers found that concentrations of the greenhouse gas near the ground also damaged plants sensitive to the gas, reducing their effectiveness to absorb carbon dioxide.
The drop was the largest in recent years but not sufficient to reverse the long-term rise in greenhouse gas emissions.
FORBES: EPA Greenhouse Gas Inventory Shows 6 Percent Drop In CO2
Power plants are the biggest source of greenhouse gas emissions in the United States.
Indonesia is the fourth-largest greenhouse gas emitter in the world.
Recently, the World Meteorological Organization (WMO) reported that greenhouse gases in the atmosphere hit a new record high in 2011.
The science here is thin: nobody knows what level of greenhouse gases in the atmosphere would trigger such a calamity.
Last week, the EPA published its GHG Emissions Report, assessing the sources and volumes of greenhouse gas emissions in the U.S. for calendar year 2010.
In 2009, the U.S. economy emitted 6, 576 million metric tons of carbon dioxide equivalent (MMTCO2e), nearly 6% below the level of emissions for 2008, according to Emissions of Greenhouse Gases in the United States 2009.
