And that's
just average temperature increases and rainfall amounts, something that doesn't affect people much.
Not exact matches
In areas like the mid-elevations of the northern Rocky Mountains, where spring
temperatures are
just under freezing in an
average year, «it doesn't take a large
increase in
temperature to start melting snow earlier in spring,» said Anthony Westerling, a professor of environmental engineering and geography at the University of California, Merced.
The study found that, if the patterns from 2002 to 2008 hold in the future, an
increase in
average temperature in Mato Grosso of
just 1 degree Celsius will lead to a nine to 13 percent reduction in overall production of soy and corn.
But
average global
temperatures will
increase dramatically if nations
just sit and wait until then, concludes the report, Redrawing the Energy - Climate Map.»
Imagine sea levels rising by feet instead of inches, global
average temperatures increasing by many degrees instead of
just fractions and an
increase in other cataclysmic, costly and fatal weather events.
[1] CO2 absorbs IR, is the main GHG, human emissions are
increasing its concentration in the atmosphere, raising
temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global
average; decreasing the
temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are
increasing in amplitude and slowing,
just like the lower Missippi River where its driving gradient decreases; the larger slower meanders
increase the amplitude and duration of blocking highs,
increasing drought and extreme
temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)
If
average global
temperatures rise by
just 3 °C, then Europe's drought risk could
increase to double the area faced with drying out.
In
just the past 30 years, the
average temperature in Alaska climbed more than 3 degrees Celsius (5 degrees Fahrenheit)-- easily four times the global
increase.
«It seems clear that climate change is happening, we continually have record
temperatures for the time of year, there is no return of
temperatures to «below
average» which we would expect if this was
just statistical variation, there is
increasing turmoil in the weather, the barrier reef is bleaching to an extent not seen before and so on.»
Well now, that is something you should take up with Webster, I
just know that more efficient mixing
increases the
average temperature of the oceans which is
increasing the total heat in the ocean system which has about 1000 times the heat capacity of the air that that heat would be lost to if the mixing didn't take place as efficiently.
A combined set of conditions including a permafrost thaw line moving rapidly northward,
increasing record heat,
temperatures that are rising at a rate twice that of the global
average, and deadwood multiplying invasive species are
just a few of the ways climate change enhances fire risk.
Although I can't lay my «hands» on the cite
just now, I recall a claim that a little cloud
increase goes a long way to decrease
average temperature (Singer, perhaps?).
The researchers discovered a
temperature increase of
just 1 degree Celsius in near - surface air
temperatures in the tropics leads to an
average annual growth rate of atmospheric carbon dioxide equivalent to one - third of the annual global emissions from combustion of fossil fuels and deforestation combined.
In the past 100 years, the earths
average surface
temperature has
increased by 0.8 °C with 2/3 occurring
just in the past 3 decades.
a)
Average Temperature rise has been steadily climbingb) It has been climbing at a «steady» rate even though our CO2 output has
increased by a hundred foldUnlike all those books, charts and pretty drawings, The numbers don't lie.CO2 is not the cause of Global Warming, the figures prove it... and they are all numbers, no charts, not hockey or cricket sticks, no drawings, animation or silly looking cartoons... all
just plain numbers.http: / / wisdomblogsdotcom1.files.wordpress.com/2011/10/coal-consumption.
Go look at the following Wikipedia page on the Maunder Minimum starting in about 1645 and lasting about 50 years noting the clear correlation between the minimal sunspot activity at the time with lower
temperatures, and then look at the chart there showing the enormous
increase in
average sunspot activity commencing in about 1945 so
just starting in and lasting through the exact same time frame of
temperature increases that Warmers especially point to as evidence for their thesis.
Surely it was important to understanding climate that after global
average temperature had been climbing at the rate of 0.15 C / decade since 1910, it switched to falling
just as rapidly in 1940 despite
increase in carbon dioxide concentration.
The scientists say that climate change and rising
average global
temperatures mean not
just drought, but drought matched with
increasing spells of prolonged heat, far more severe than anything experienced in the 20th century.
I.e. if the
temperature increase due to the «current loading» is 1.8 per century,
just as the models predict, the
average rate over time must be lower because the
average «loading» was lower.
«The global
average surface
temperature trend of late is like a speed bump, and we would expect the rate of
temperature increase to speed up again
just as most drivers do after clearing the speed bump.»
