Arctic Ice Growth Since 1971Posted: July 31, 2013
Nat Geo news 2008:
“With additional heating due to global warming, the extent of sea ice cover has gotten smaller and smaller over the summers since the 1980s”
Look forward to the 2013 Arctic Ice Death Spiral update: “We’ve got no idea what we’re talking about. However human’s are still to blame, the problem of global warming has not gone away. ”
Reader Brian D sent over this 1971 National Geographic map, which shows that there is a lot more Arctic sea ice now than there was 42 years ago.
I remember seeing that map at the time. The next map overlays current ice extent on the 1971 map, with green representing ice present in 2013 that was not present in 1971, and red representing the opposite.
NSIDC likes to pretend that ice has been declining steadily, by starting their graphs near the century maximum in 1978.
But sadly for them, the 1990 IPCC report captured the growth in ice prior to 1979.
NCAR mentioned the ice growth at the time
