Record heat: Month of May is hottest on Earth

Why do you people waste your time with this?
Has anyone's mind been changed?
Insane.

Chiloe, you give them a forum to air their "ideas", and give them legitimacy by responding to them and taking them seriously.

Don't debate such people. It only makes them stronger and makes you look idiotic.

The new NASA Terra satellite data are consistent with long-term NOAA and NASA data indicating atmospheric humidity and cirrus clouds are not increasing in the manner predicted by alarmist computer models. The Terra satellite data also support data collected by NASA’s ERBS satellite showing far more longwave radiation (and thus, heat) escaped into space between 1985 and 1999 than alarmist computer models had predicted. Together, the NASA ERBS and Terra satellite data show that for 25 years and counting, carbon dioxide emissions have directly and indirectly trapped far less heat than alarmist computer models have predicted.

In short, the central premise of alarmist global warming theory is that carbon dioxide emissions should be directly and indirectly trapping a certain amount of heat in the earth’s atmosphere and preventing it from escaping into space. Real-world measurements, however, show far less heat is being trapped in the earth’s atmosphere than the alarmist computer models predict, and far more heat is escaping into space than the alarmist computer models predict.

When objective NASA satellite data, reported in a peer-reviewed scientific journal, show a “huge discrepancy” between alarmist climate models and real-world facts,

As for me looking idiotic, that would be in the eye of the beholder. I do my best to avoid actually being an idiot though.

You have to fight back against these provocateurs.
What else can we do?

It is a moral question

It is a failure of imagination, not at a policy level but at the level of civilization.

Two years ago during the scorching summer of 2012, July 1936 lost its place on the leaderboard and July 2012 became the hottest month on record in the United States,” Watts wrote. “Now, as if by magic, and according to NOAA’s own data, July 1936 is now the hottest month on record again. The past, present, and future all seems to be ‘adjustable’ in NOAA’s world.”

Varying levels of boreal summer insolation and associated Earth system feedbacks led to differing climate and ice-sheet states during late-Quaternary interglaciations. In particular, Marine Isotope Stage (MIS) 11 was an exceptionally long interglaciation and potentially had a global mean sea level 6 to 13 metres above the present level around 410,000 to 400,000 years ago1, 2, implying substantial mass loss from the Greenland ice sheet (GIS). There are, however, no model simulations and only limited proxy data3, 4 to constrain the magnitude of the GIS response to climate change during this ‘super interglacial’5, thus confounding efforts to assess climate/ice-sheet threshold behaviour6, 7 and associated sea-level rise1, 2. Here we show that the south GIS was drastically smaller during MIS 11 than it is now, with only a small residual ice dome over southernmost Greenland. We use the strontium–neodymium–lead isotopic composition of proglacial sediment discharged from south Greenland to constrain the provenance of terrigenous silt deposited on the Eirik Drift, a sedimentary deposit off the south Greenland margin. We identify a major reduction in sediment input derived from south Greenland’s Precambrian bedrock terranes, probably reflecting the cessation of subglacial erosion and sediment transport8 as a result of near-complete deglaciation of south Greenland. Comparison with ice-sheet configurations from numerical models7, 9, 10, 11, 12 suggests that the GIS lost about 4.5 to 6 metres of sea-level-equivalent volume during MIS 11. This is evidence for late-Quaternary GIS collapse after it crossed a climate/ice-sheet stability threshold that may have been no more than several degrees above pre-industrial temperatures6, 7.

Anomalous MIS11 Arctic warmth5 and a seasonally ice-free ocean30 could have pushed the GIS past an ice-stability threshold6,7 that was not crossed during the LIG or early Holocene. Alternatively, protracted warmth during the long MIS 11 interglaciation may have allowed the GIS to respond fully to interglacial conditions that were similar to the early Holocene and LIG [last interglacial], with these later interglaciations being too short for comparable ice-sheet collapse. A more extensive network of Pleistocene climate and ice-extent records around Greenland is required to assess these alternative scenarios, which have important implications for predicting the long-term behaviour of the GIS in response to future climate change scenarios6,7. In this context, our evidence for a late-Quaternary collapse of the south GIS provides an important example of geologically recent ice-sheet instability and retreat under climate conditions within the range of those anticipated by the end of this century.
