Increases in CO2 - Causes Cooling

this is just what I have been concerned about.

CO2 causing Increased Cooling of Atmosphere

As demonstrated in Rescue from the Climate Saviors, increasing levels of CO2 and other IR-active gases in the atmosphere increase the natural cooling system of the earth. IR-active gases do not supply additional heating power to the earth and are not a cause of “global warming”. IR-active gases do not act “like a blanket” but rather “like a sunshade”. They keep a part of the solar energy away from the earth’s surface and act to cool the earth: 70% of the entire cooling power originates from these molecules. An increase in concentration only serves to increase the cooling efficiency, and now there is additional empirical evidence. A new paper shows that increased CO2 concentrations have increased the cooling efficiency of the upper atmosphere, and in combination with the 2008 solar minimum, resulted in the lowest upper atmospheric density recorded in 43 years.


(PhysOrg.com 6/21/10) -- A team of scientists from the Naval Research Laboratory and George Mason University reports that the Earth's upper atmosphere has recently experienced the lowest density in 43 years. The team has published its findings in a paper entitled "Record-low thermospheric density during the 2008 solar minimum" that appeared in Geophysical Research Letters in June 2010.


The team of Dr. John Emmert and Dr. Judith Lean from NRL's Space Science Division and Dr. Michael Picone from George Mason University were studying the Earth's upper atmosphere between 200 and 600 km altitude. Although the air density at these altitudes is only about one-billionth of that at the Earth's surface, it provides sufficient drag on Low Earth Orbit (LEO) objects to cause their eventual reentry. "An operational consequence of this important new finding is that LEO satellites, including debris, may remain in orbit longer than expected," explains Emmert.

To describe their results, the researchers pointed out that the air density at orbital altitudes is ultimately linked to the temperature of the upper atmosphere. A hotter upper atmosphere will expand in vertical extent and increase the air density at a given altitude. The two major factors that control upper atmosphere temperatures are heating via absorption of ultraviolet (UV) radiation from the Sun, and cooling via CO2 infrared emission.

The Sun was unusually quiet during the prolonged solar minimum of 2007-2009, and the research team found that the associated reduction in solar UV heating can partly explain the reduction in density. Increasing concentrations of CO2 near the Earth's surface are likely making their way into the upper atmosphere and are thus increasing the upper atmosphere cooling efficiency. However, it is not yet clear whether the combination of reduced solar UV heating and enhanced CO2 cooling can fully account for the occurrence of the anomalously low thermospheric density, and the researchers suggested that changes in upper atmospheric chemistry and composition may have also contributed to the record-low density.

 

co2 might not be a blanket it might be a sun shade.....


you do remember this from NASA... I did not realize this observation confirmed the previous paper... its unbelievable we have leftist morons going around saying what actually might be completely opposite of scientific reality.

Mlynczak is the associate principal investigator for the SABER instrument onboard NASA’s TIMED satellite. SABER monitors infrared emissions from Earth’s upper atmosphere, in particular from carbon dioxide (CO2) and nitric oxide (NO), two substances that play a key role in the energy balance of air hundreds of km above our planet’s surface.
“Carbon dioxide and nitric oxide are natural thermostats,” explains James Russell of Hampton University, SABER’s principal investigator. “When the upper atmosphere (or ‘thermosphere’) heats up, these molecules try as hard as they can to shed that heat back into space.”
That’s what happened on March 8th when a coronal mass ejection (CME) propelled in our direction by an X5-class solar flare hit Earth’s magnetic field. (On the “Richter Scale of Solar Flares,” X-class flares are the most powerful kind.) Energetic particles rained down on the upper atmosphere, depositing their energy where they hit. The action produced spectacular auroras around the poles and significant1 upper atmospheric heating all around the globe.
“The thermosphere lit up like a Christmas tree,” says Russell. “It began to glow intensely at infrared wavelengths as the thermostat effect kicked in.”

 

here is more from a long article...

Finally, the IR radiation is not absorbed by nitrogen, oxygen, and argon gases which make up 99% of the atmosphere, so a large fraction of it directly warms the Earth's surface. Some, is absorbed by the dominant greenhouse gas, water vapor, and small amounts are absorbed by carbon dioxide and other greenhouse gases. The incoming IR radiation absorbed in the atmosphere is less effective in warming the Earth's surface than is that which is absorbed by the Earth's surface directly. This is because some this energy absorbed in the atmosphere then is radiated again in the form of IR radiation, but now half or more of that is directed out to space. In other words, more water vapor and CO2 in the atmosphere results in a less effective warming of the surface than does less of these gases with respect to the incoming IR energy from the sun. The greenhouse gases have a cooling effect on the original solar radiance spectrum for the 45% of the solar energy in the form of IR.

 

And what about CO2 in the lower atmosphere, where we live, you lying sack of shit.

 

Too many climate threads.

 

. Loss of Biodiversity
Species loss and endangerment is rising along with global temperatures. As many as 30 percent of plant and animal species alive today risk extinction by 2050 if average temperatures rise more than 2 to 11.5 degrees F (1.1 to 6.4 degrees C) [sources: EPA , Scientific American ]. Such extinctions will be due to loss of habitat through desertification, deforestation and ocean warming, as well as the inability to adapt to climate warming. Wildlife researchers have noted some of the more resilient species migrating to the poles, far north and far south to maintain their needed habitat; the red fox, for example, normally an inhabitant of North America , is now seen living in the Arctic.

Humans also aren't immune to the threat. Desertification and rising sea levels threaten human habitats. And when plants and animals are lost to climate change, human food, fuel and income are lost as well.

There is a special place in hell for lying scumbags like jerm. Assholes like him are obstructing doing something about CO2 pollution which threatens the earth and mankind and will be catastrophic if we don't act.

He's the same kind of scumbag liars like those that said cigarettes were OK and like the kind of scumbag lawyers that defended OJ.

Hey jem. Fuck you.

 

co2 is plant food you moron... if you watched the video I posted a few days ago you would see the images showing the world greening. its the opposite of the crap you post.

 

Fuck you you lying piece of shit.

 

1. Destruction of Ecosystems
Changing climatic conditions and dramatic increases in carbon dioxide will put our ecosystems to the test, threatening supplies of fresh water, clean air, fuel and energy resources, food, medicine and other matters we depend upon not just for our lifestyles but for our survival.

Evidence shows effects of climate change on physical and biological systems, which means no part of the world is spared from the impact of changes to land, water and life. Scientists are already observing the bleaching and death of coral reefs due to warming ocean waters, as well as the migration of vulnerable plants and animals to alternate geographic ranges due to rising air and water temperatures and melting ice sheets.

Models based on varied temperature increases predict scenarios of devastating floods, drought, wildfires , ocean acidification and eventual collapse of functioning ecosystems worldwide, terrestrial and aquatic alike.

Forecasts of famine, war and death paint a dire picture of climate change on our planet. Scientists are researching the causes of these changes the vulnerability of Earth not to predict the end of days but rather to help us mitigate or reduce changes that may be caused by humans. If we know and understand the problems and take action through adaptation, the use of more energy-efficient and sustainable resources and the adoption of other green ways of living, we may be able to make some impact on the climate change process.
