How dramatically is global warming really? NASA researchers
have shown that the temperature rise has taken a break for 15
years. There are plenty of plausible explanations for why global warming
has stalled. However, the number of guesses also shows how little the
climate is understood.
Bojanowski calls “NASA scientists” on their predictions
:
…it has become common knowledge for some time that the
climate has recently developed differently than predicted. The warming
has stalled for 15 years; the upward trend in the average global
temperature has not continued since 1998 (sic). “The standstill has led
to the suggestion that global warming has stopped,” NASA admit.
IPCC meeting
Scientists previously thought 14 years without further warming could
be brought into line with their forecasts – but not “15 years or more,”
as NASA scientists stated four years ago in the journal “Bulletin of the
American Meteorological Society”. In an email to colleagues a renowned
scientist wrote on 7 May 2009, at a time when the warming standstill had
already lasted for eleven years: “the ‘no upward trend’ has to continue
for a total of 15 years before we get worried.”
Now, 15 years without warming has happened. The
warming standstill of the global surface temperature shows that the
uncertainties of climate predictions are surprisingly large. The
interested public anxiously awaits whether the IPCC’s new Assessment
Report, which is due in September, will address the warming pause – the
discussions are ongoing in Australia’s Hobart. The researchers are
discussing several cogent reasons that might have slowed the upward
trend of temperatures.
