A less sensitive climate system would mean
average warming of less than 2 degrees C and, therefore, fewer ramifications from global warming.
The scaling process removes the difference in magnitude between the larger
average warming trends in the 20th century simulations, and the smaller trends in the control.
Interestingly, the models that best simulate the recent past of these energy exchanges between the planet and its surroundings tend to project greater - than -
average warming in the future.
Since the daytime side is
on average warmer than the night - time side, then all other things (e.g. cloud cover, etc.) more IR will escape on the day side.
21 (5) The climate future of the Planet: global warming predictions The
globally averaged warming corresponds to 3.0 °C (5.4 °F).
If average warming is instead caused by increased carbon dioxide, then a cooling trend is unlikely to start on its own.
One reason for this is that many impacts of climate change are expected to be proportional to the amount of
global average warming that occurs over the next several decades to centuries.
The Japan Meteorological Agency said sea surface temperatures around Japan had been up by an average of 1.07 degrees Celsius in the past 100 years, which is double the global
average warming rate.
Yep, no matter how one slices and dices the 5 -
year average warming amounts, the modern era's warming represents an increase not even one - tenth of a degree greater than the pre-1950 warming — it is not only a statistically worthless difference, it is completely climate insignificant.
How for example can you explain that the region on earth that is most likely to suffer a greenhouse effect; Antarctica, is not on
average warming at all?
This new research confirmed those observations,
with average warming rates of 1.3 degrees Fahrenheit (0.72 degrees Celsius) per decade at high latitudes.
If I have understood e.g. the IPCC report correctly, it is not only what climate change will do to the distribution centroids (e.g. induce an overall
annual average warming of, say, the nothern hemisphere air temperature) that is important, but what goes on at the tails (upper and lower) of the distribution.
There is medium confidence that approximately 20 to 30 percent of species assessed so far are likely to be at increased risk of extinction if increases in global
average warming exceed 1.5 to 2.5 °C (relative to 1980 to 1999).
The target, which represents the reduction that industrialized countries such as the United States will have to achieve to keep global
average warming from reaching catastrophic levels, has been criticized as being unachievable without ruining the nation's economy.
This was very well explained in Steve McIntyre's latest blog article two minutes to midnight where he showed that over the period 1979 - 2013 models on
average warm up 50 % faster than the real -LSB-...]
Christy is correct to note that the
model average warming trend (0.23 °C / decade for 1978 - 2011) is a bit higher than observations (0.17 °C / decade over the same timeframe), but that is because over the past decade virtually every natural influence on global temperatures has acted in the cooling direction (i.e. an extended solar minimum, rising aerosols emissions, and increased heat storage in the deep oceans).
Average warming onset rate of change is approximately 2.0 degrees C / millennium in the Antarctic with exceptionally strong correlation coefficients of 0.98.
By 2050, two models show that the global mean annual
average warming due to long - lived GHGs is enhanced by 20 - 25 % due to the short - lived species (Figure 1).
Summing up: My question for sTeve is: why would you choose the GISS estimate of temperatures, which shows parts of the past decade as higher than 1998 and
considerable average warming, over the other three monitoring agencies, which show much less or no warming for the decade?
Despite large uncertainties, a recent World Bank report warns that it increasingly plausible that this has put the world on a 4 ° C
average warming path within the 21st century.
The fundamental question at the Paris summit, according to Kolbert, «is who should be allowed to emit the tons [of carbon]» that scientific estimates suggest can still be released this century without
pushing average warming above two degrees.
The histograms all show
similar average warming trends and the stations with the longest measurement durations show the least dispersion of temperature trends.
You may wish to distort the language so much as to say faster than
centenial average warming is no warming - but that only tells us something about you.
Love to have an explanation of the differences between the data sets (
what average warming trend they are showing and why they «might» be different) and if there are discrepancies between the actual data and any modeling for the same period.
If the 195 nations that signed a climate accord in Paris in 2015 actually honour their collective vow to contain
planetary average warming to about 1.5 °C above historic averages, there will still be record - breaking temperatures and more intense extremes of wet and dry — but over a smaller proportion of the globe, according to a new study.
Global
average warming over the 21st century «will substantially exceed even the warmest Holocene conditions, producing a climate state not previously experienced by human civilizations.»
