Satellites confirm 2014 was a long way from being the ‘hottest ever year’

UAH Confirms 2014 Was Not Hottest Year

By Paul Homewood UAH have now released their global temperature data for December and, as with RSS, they confirm that 2014 was a long way from being the “hottest ever year”, much touted recently. http://vortex.nsstc.uah.edu/data/msu/t2lt/uahncdc_lt_5.6.txt Whereas RSS have last year ranked only the 6th warmest, according to UAH it is 3rd. However, as Dr John Christy points out: http://nsstc.uah.edu/climate/2014/december2014/dec2014GTR.pdf It is commonly claimed that satellite and surface datasets measure different things, and there is an element of truth in that. Whereas surface sets, such as HADCRUT and GISS, only measure the temperature at the bottom of the atmosphere, the satellite sets of UAH and RSS measure it through the whole of the lower troposphere, and therefore must be regarded as much more comprehensive. It is also argued that UAH do not measure sea surface temperatures. However, in terms of global heat balance, the temperature of the sea at the surface is almost irrelevant when compared to that of the entire volume of sea from top to bottom. In any event, increased heat at the top of the sea will always tend to transfer into the atmosphere above it by evaporation, until equilibrium is found. While there is a short lag for this to happen, atmospheric temperature measurements do reflect these changes. It is also worth pointing out that higher sea temperatures can only affect land ones after having also affected the atmosphere. Indeed, according to theory, the global troposphere should warm 1.2 times as fast as the surface. Satellite coverage measures nearly every cubic inch of the lower atmosphere on a daily basis, apart from close to the poles, where of course there is virtually no surface coverage anyway. Satellites are also not affected by the well established issues that surface data has, such as UHI, bad siting, sparse coverage and endless adjustments. The reality is that, despite El Nino conditions for most of the year, the long pause in global temperatures has continued for another year. With the MEI Index suggesting that last year’s El Nino is weakening, it seems likely that 2015 will be any different.

Der Spiegel Dumps Cold Water On ‘Record Warm Year’ Significance … Sees Science Fraught With Widespread Uncertainty

Spiegel Dumps Cold Water On “Record Warm Year” Significance … Sees Science Fraught With Widespread Uncertainty

http://notrickszone.com/2015/01/08/spiegel-dumps-cold-water-on-record-warm-year-significance-sees-science-fraught-with-widespread-uncertainty/

Now that a couple of surface temperature data sets are showing 2014 was a “record warm year,” people are wondering if it means the warming pause is over, and if so, how much climate sensitivity to CO2 there really is. Online Spiegel science journalist Axel Bojanowski (a geologist) has an analysis of 2014’s “record warm year” and asks if it means global warming has resumed after “a pause since the end of the 1990s”. He describes how climate scientists have been dumbfounded by the “unexpected warming pause”. A number of scientists blame the oceans for absorbing the heat out of the atmosphere. Japan’s meteorological services report that global surface temperature has risen 0.7°C in one hundred years, he writes. On the significance of the warm year, the Spiegel science journalist quotes the German Climate Consortium: “The following years will allow us to judge the extent global warming at the surface of the earth has resumed.” And even the most alarmist organizations are conceding the global warming pause is real. For example the World Meteorological Organization (WMO) indirectly admits to Spiegel that the global temperature has paused, but reminds us that the 14 warmest years on record occurred over the past 15 years. On the future of warming, Bojanowski describes a science fraught with uncertainty when it comes to future projections: The UN IPCC continues to predict a hefty global warming should carbon dioxide emissions not be drastically reduced. But there are major uncertainties in the calculations and for this reason short-term fluctuations will remain unexplainable.” Readers should note at this point that this too also has to apply for “short-term” warm fluctuations, such as the one from 1980-1998. That one too must have been in large part due to natural factors. Bojanowski sums up his analysis by pointing out there is also uncertainty not only at the earth’s surface, but in the troposphere as well, writing that “satellite meaurements are astonishing” researchers: Moreover satellite measurements for upper air levels, which have been taken since the mid 1990s, show hardly any warming. Because of this, scientists are debating if the sensitivity of air temperature with respect to greenhouse gases is possibly less than assumed.” Bojanowski also points to conflicting scientific literature and papers when it comes to the stability of the Antarctic and Greenland …

Here are some highlights of these two new papers published in Physics Letters A by David H. Douglass & Robert S.Knox: Central Pacific region temperature dataset SST3.4 from 1990 to 2014 is studied. SST3.4 contains a sustained signal at 1.0 cycle/yr implying solar forcing. SST3.4 also contains a signal (<1 cycle/yr) showing […] -- gReader Pro …

Gruber Thinking in Climate Science: Disconnect Between Academia And The Real World.

There are many parallels between the Jonathan Gruber story and what has occurred in climate science. Gruber used a computer model to produce justification for a US national healthcare system. This parallels the Intergovernmental Panel on Climate Change (IPCC) use of computer models produced to justify the need for international climate control. They both claim […]

Indian Science Conference: 2 of 3 scientists say ‘fears of man-made global warming were greatly exaggerated’

http://economictimes.indiatimes.com/news/environment/global-warming/fears-of-man-made-global-warming-exaggerated/articleshow/45786412.cms

MUMBAI: Two of three scientists at a session on climate change and society at the Indian Science Congress on Tuesday felt fears of man-made global warming were greatly exaggerated. Their presence at the conference was particularly significant in light of the current ‘development-versus-envir- onment’ debates.

“While I agree that glaciers are melting because of global warming, if this is because of man, then what was the reason for the melting of the glaciers in the Gondwana period long ..

Rajesh Agnihotri senior scientist at the Radio and Atmospheric Science Division, National Physics Laboratory, who mapped changing trends in India’s monsoons, said there was nothing to suggest that this was because of man-made climate change.

Hypothetically, even if man stopped industrial activity, stopped using cars and stopped using air-conditioners, monsoon patterns would still change,” said Agnihotri.

“Natural forces like solar intensity appear to be dominating monsoons to a ..
