Antarctic Losing Tiny Amounts Of Ice (Or Maybe It’s Gaining Ice, NASA Is Not Sure!)

by P. Homewood, January 15, 2019 in NotaLotofPeopleKnowThat


Antarctica is shedding ice at a staggering rate.

Scientists have discovered global warming has caused the melting of the ice on the continent to increase sixfold since 1979.

This phenomenal rate of melting has seen global sea levels rise by more than half an inch – and experts predict it will get worse. 

Scientists have predicted a ‘multi-meter sea level rise from Antarctica in the coming centuries’ as a result of the vast loss of ice.

Researchers discovered that, between 1970 and 1990, the continent was shedding an average of 40 gigatons of ice mass annually.

This jumped to an average of 252 gigatons a year between 2009 and 2017.

You may of course recall that it was only three years ago that the same NASA, who are behind this latest scare story, were telling us that the ice cap was actually growing in Antarctica. But more of that in a minute.

There are several aspects to this latest story that need closer examination.

NASA: Global Warming Promotes Arctic Sea Ice Growth

by Eric Worrall, December 11, 2018 in WUWT


According to NASA, the increased rate of thickening of sea ice in the Arctic is due to Global Warming.

The abstract of the study:

I guess we should count ourselves lucky the world isn’t currently in a cooling phase, otherwise we might lose the Arctic icepack altogether.

 

La baisse de l’activité solaire conduit la NASA à annoncer un refroidissement climatique

by Anne Dolhein, 2 october 2018 in Reinformation.TV


La NASA – peu suspecte de climato-scepticisme – s’appuie sur de nouveaux résultats d’observations de température aux confins de l’atmosphère terrestre pour annoncer un refroidissement notable dans ces zones, lié à l’un des minima solaires les plus importants de l’ère spatiale. Il s’agit très clairement d’un refroidissement climatique entraîné par la baisse de l’activité solaire, confirmant le rôle important sinon prépondérant du soleil sur les variations de température de la planète.

« Nous constatons une tendance au refroidissement », vient ainsi de déclarer Martin Mlynczak, chercheur principal associé du centre de recherches Langley de la NASA. « Très loin de la surface de la terre, près du bord de l’espace, notre atmosphère perd de l’énergie calorifique. Si les tendances actuelles se poursuivent, on pourrait bientôt atteindre un record de froid pour notre ère spatiale », a-t-il affirmé.

NASA: The chill of solar minimum is being felt in our atmosphere – cooling trend seen

by Anthony Watts, September 28, 2018 in WUWT


These results come from the SABER instrument onboard NASA’s TIMED satellite. SABER monitors infrared emissions from carbon dioxide (CO2) and nitric oxide (NO), two substances that play a key role in the energy balance of air 100 to 300 kilometers above our planet’s surface. By measuring the infrared glow of these molecules, SABER can assess the thermal state of gas at the very top of the atmosphere–a layer researchers call “the thermosphere.”

When the thermosphere cools, it shrinks, literally decreasing the radius of Earth’s atmosphere. This shrinkage decreases aerodynamic drag on satellites in low-Earth orbit, extending their lifetimes. That’s the good news. The bad news is, it also delays the natural decay of space junk, resulting in a more cluttered environment around Earth.

NASA alarmism headline: ‘A World On Fire’

by Anthony Watts, August 23, 2018 in WUWT


The world is on fire. Or so it appears in this image from NASA’s Worldview. The red points overlaid on the image designate those areas that by using thermal bands detect actively burning fires. Africa seems to have the most concentrated fires. This could be due to the fact that these are most likely agricultural fires. The location, widespread nature, and number of fires suggest that these fires were deliberately set to manage land. Farmers often use fire to return nutrients to the soil and to clear the ground of unwanted plants. While fire helps enhance crops and grasses for pasture, the fires also produce smoke that degrades air quality.

Multiple NASA Studies Confirm Bedrock Heat Flow Behind Melting Polar Ice, Not Global Warming

by James E. Kamis, August 7, 2018 in ClimateChangeDisatch


In what amounts to dissension from National Aeronautics and Space Administration (NASA) climate change policy, a series of just-released studies by working-level scientists prove that geological and not atmospheric forces are responsible for melting of Earth’s polar ice sheets.

Claim: U.N. data reflects greening of the Earth, not carbon dioxide

by A. Watts, May 15, 2018 in WUWT


NASA says the greening of the planet is due to increased CO2, these guys are arguing against that, saying increased forest growth “correlates strongly to the UN Development Programme’s Human Development Index”. Riiiighht. They say that “Europe’s early turnaround and expansion of forest resources obviously can’t be attributed to the rapid rise of atmospheric carbon dioxide that began decades later”. By the same token, the U.N. didn’t exist until decades later, and they sure as hell haven’t had any impact on the greening of the Eastern United States as shown in their map below (…)

NASA finds something else climate models are missing…. forcing from ‘Secondary Organic Aerosols’

by Anthony Watts, March 27, 2018 in WUWT


A new paper published by NASA by Tsigaridis and Kanakidou suggests that climate models have missed the forcing effects of organic aerosols, such as VOC’s from trees, oceans, and other sources that combine chemically in the atmosphere to create new compounds. Known as Secondary organic aerosols (SOA), they say “SOA forcing could exceed that of sulfate and black carbon”.
