2011 Much Cooler Than 2010 So Far (records, temp, freezing, degree)

Ah ok, that makes sense then.

As for this year, the heat was more widespread than last year.

Most places in the Upper Midwest were just consistently warm (and very wet) in 2010 versus experiencing any extreme heat. For example Detroit had a lot of cloudy days, very few sub-80 degree days and not one day above 94*F, and I think only one legit 3-day heatwave, although it was a top 4 hottest summer here). This summer the extreme heat was more widespread, thanks largely to the severe drought in the central/southern plains, versus just confined across the east coast and far south. For example Detroit had a 7-day stretch at/above 90*F, one 100*F and two near 100*F days, then several 95*F+ days, not to mention far more sunny days, and this season Detroit had a record number of days consistently at/above 80*F and a record hottest July. Interestingly enough this summer tied for the 4th hottest with 2010 for Detroit, both of which surpassed 1988.

As someone who loves the climate of the planet just like it is (lol)…that’s good news that so far 2011 is cooler than 2010 (up to this point). I hope for total stability in our global climate!

However…in terms of global warming…there still have been several troubling things that happened this year:

1) On September 9, 2011….the Arctic sea ice extent was very close to the record low set in 2007 (2011 is now the 2nd lowest on record), according to the National Snow and Ice Data Center (NSIDC). However, scientists at the University of Bremen, who use a slightly different method to calculate sea ice extent from AMSR-E measurements, actually declared that 2011 surpassed 2007, setting a new record low Arctic sea ice level, according to NASA's Earth Observatory:

Here a link by NASA showing how quick the sea ice melted in summer 2011:

2) If citizens of Europe, Canada, the America’s, and Asia thought summer 2011 was hotter than normal – they were correct: The summer of 2011 was the fifth warmest on record in the northern hemisphere since records began back in 1880, according to the Goddard Institute for Space. NYC had its warmest summer in156 years of record keeping at the same spot:

3) August 2011 was the sixth warmest August on record globally for the lower troposphere, according to Remote Sensing Systems, as measured by microwave sounding data from satellites. The satellite measured records go back to 1979.

Keep in mind the northern hemisphere leaves more of a footprint on global mean temps than the southern hemisphere (much more land in the NH). We still have several months to go before we’ll know how 2011 will average into the long term global mean temps.

And it was bloody freezing in the UK, coldest summer since 1988.

[dunno what to put here]

Summer was very cool in France, Belgium and the Netherlands too. South-west France had a summer more acceptable to Aberdeen than Toulouse and my friend in Paris tells me this hot spell in September/October has been their best weather all year.

June/July have been colder than usual in the southern hemisphere
While August has been more or less similar (maybe a bit warmer) than usual August, and September has been sunny and warm, overall like every year.
I do think that 2011 summer (from january till march) was as hot as every summer.

So, if you add to that the fact that US summer was very hot this year (hoter than usual), then i wonder where this "much cooler than 2010" comes from (?). Maybe Europe?

this might help:

but look at Europe and Asia last winter!

[SophieLL]

i dont understand that chart (?)
the circles refer to the actual temperature or to the difference between one year and another (?)?

Anomaly map. Winter was 5 degrees colder than average in parts of Europe for example, but 5 degrees warmer in parts of Canada.
