CO2 Coalition 's " Fact #15 " wants us to believe that temperatures even 8°C warmer than today would be just fine for humanity. In order to make that claim, they need to perform a few tricks. The first trick is to make that 8°C Greenland temperatures instead of global temperatures. The second trick is to redefine  "today" as "the mean of the past millennium." Here's how they say it The results revealed that the Eemian interglacial warm period, between 130,000 and 115,000 years ago, was much warmer than previously thought. In fact, it was, 8°C (14.4°F) warmer than today. Their source for this is Dahl-Jensen 2013[1], which details the results of the new North Greenland Eemian (NEEM) Ice Drilling ice core. The paper concludes: NEEM surface temperatures after the onset of the Eemian (126,000 years ago) peaked at 8 ± 4 degrees Celsius above the mean of the past millennium, followed by a gradual cooling that was probably driven by the decreasing summer i...

Greenland's Contribution to Sea Level Rise Since 1992 In 2019, Tony Heller posted on his blog that "Over the past three years, Greenland’s surface has gained 1.2 trillion tons of new ice... Experts in the press corps have generously interpreted the data for us, and determined that there is a climate emergency and it is President Trump’s fault." He then showed graphs supporting that Greenland's surface mass balance (SMB) did indeed gain ice each of those years, totaling 1.2 trillion tons of ice.  What Heller doesn't tell you is that Greenland's SMB gains ice pretty much every year, but it also loses ice every year due to glacial calving and basal melting; this is referred to as discharge (D). In order to assess whether Greenland gained or lost ice, what is referred to as total mass balance (TMB) you have to account for both SMB and D. The equation for this is not that hard: TMB = SMB + D Heller was capable of looking up the value for SMB but neglected to look u...

Total Mass Balance Change For the 25th year in a row, the Greenland Ice Sheet (GrIS) lost ice. The total mass balance (TMB) is calculated by accounting for 1) the surface mass balance (SMB), where accumulation at the top of the ice sheet normally exceeds ablation and 2) ice discharge (D) which is the loss of ice through glacial calving and basal melting where glaciers are in contact with seawater. For the 25th year in a row, the loss of ice from discharge exceeded mass gains from the surface. There were several notable features and events from the GrIS in 2021: 1. The loss of mass from ice discharge was the largest amount since satellite observations began in 1986. 2. It rained at the top of the GrIS at a station 3216 m above sea level. 3. For the third time in a decade, scientists have observed a melt layer at the station (2021, 2019 and 2012). Melt layers have only been observed 6 times previously over the last 2000 years: 1889, 1094, 992, 758, 753 and 244. Resources: [1] "Polar...
