Over the past few years, government experts have reversed many climate stories in order to fall in line with government objectives.
Two years ago, NASA’s top polar scientist said that Antarctica was gaining ice at a rate of 49.000.000,000,000 kg/year
Mass Gains of the Antarctic Ice Sheet Exceed Losses

During 2003 to 2008, the mass gain of the Antarctic ice sheet from snow accumulation exceeded the mass loss from ice discharge by 49 Gt/yr (2.5% of input), as derived from ICESat laser measurements of elevation change. The net gain (86 Gt/yr) over the West Antarctic (WA) and East Antarctic ice sheets (WA and EA) is essentially unchanged from revised results for 1992 to 2001 from ERS radar altimetry

Since then, Antarctic sea ice has also set an all-time record, and alarmists have gotten stuck in the excess ice. None of this worked for the political agenda, so they simply sponsored a new “study” which concluded :
Three years’ worth of readings from the European Space Agency’s CryoSat 2 satellite indicate that Antarctica’s ice sheets are losing 159 billion tons of ice per year — which is twice as much as the estimates from previous altimeter surveys.

Previous altimeter surveys showed that Antarctica was gaining ice, not losing it. Unlike sea ice, which anyone can analyze in two dimensions – altimetry of land ice involves changes in the third dimension, which is not visible from photography. Thus they can switch their story, and no one can prove them wrong – except for themselves, who already did.
Every climate story reverses to support the agenda. NASA used to say the US is cooling. Now they say it is warming. NASA used to say Antarctica is cooling. Now they say it is warming. NASA used to say we were headed into an ice age by 2021, now they say we are headed for a meltdown. NASA used to say that satellite temperatures were more accurate, now they ignore them.
