Record Heat Bakes #Australia - #GOP Climate Experts say..."Uh!"

Australia experiences its hottest two years on record

High temperatures, which are forecast to continue through winter, are a clear sign of climate change, report warns

Press) – Australia has experienced its hottest two years on record and high temperatures are set to continue through winter in a clear sign of climate change, a report warns.
May 2012 to April 2014 was the hottest 24-month period ever recorded in Australia, but that is likely to be eclipsed by the two years between June 2012 and May 2014, according to the Climate Commission's latest report, Abnormal Autumn.

"We have just had an abnormally warm autumn, off the back of another very hot 'angry summer'," Professor Will Steffen of the Climate Council said.

"The past two-year period has delivered the hottest average temperature we have ever recorded in Australia.

"Climate change is here, it's happening, and Australians are already feeling its impact."

The average temperature across Australia in April was 1.11C above the long-term average, the report says, citing Bureau of Meteorology figures.

The average minimum temperature was 1.31C above normal.

Unseasonable temperatures in the autumn "warm wave" set records, with Sydney, Adelaide, and Melbourne setting benchmarks for the consecutive number of May days when the mercury reached 20C or higher.

In its report, the Climate Council says the abnormally warm weather in April and May "are part of a longer-term trend towards hotter conditions in the summer months and more warm spells in autumn and winter"

Real Climate - SUPER #ELNINO COMING SOON!

(RealClimate) – Much media attention has been directed at the possibility of an El Niño brewing this year. Many outlets have drawn comparison with the 1997-98 super El Niño. So, what are the odds that El Niño will occur? And if it does, how strong will it be?

To track El Niño, meteorologists at the NOAA/NWS Climate Prediction Center (CPC) release weekly and monthly updates on the status of the El Niño-Southern Oscillation (ENSO). The International Research Institute (IRI) for Climate and Society partner with us on the monthly ENSO release and are also collaborators on a brand new “ENSO blog” which is part of www.climate.gov (co-sponsored by the NOAA Climate Programs Office). 


Blogging ENSO is a first for operational ENSO forecasters, and we hope that it gives us another way to both inform and interact with our users on ENSO predictions and impacts. In addition, we will collaborate with other scientists to profile interesting ENSO research and delve into the societal  

dimensions of ENSO.
As far back as November 2013, the CPC and the IRI have predicted an elevated chance of El Niño (relative to historical chance or climatology) based on a combination of model predictions and general trends over the tropical Pacific Ocean. Once the chance of El Niño reached 50% in March 2014, an El Niño Watch was issued to alert the public that conditions are more favorable for the development of El Niño.

Accurate 1972 Global Warming Targets

A remarkably accurate global warming prediction, made in 1972

By Dana Nuccitelli   

(Guardian) – John Stanley (J.S.) Sawyer was a British meteorologist born in 1916. He was elected a Fellow of the Royal Society in 1962, and was also a Fellow of the Meteorological Society and the organization's president from 1963 to 1965.

A paper [pdf] authored by Sawyer and published in the journal Nature in 1972 reveals how much climate scientists knew about the fundamental workings of the global climate over 40 years ago. For example, Sawyer predicted how much average global surface temperatures would warm by the year 2000.

"The increase of 25% CO2 expected by the end of the century therefore corresponds to an increase of 0.6°C in the world temperature – an amount somewhat greater than the climatic variation of recent centuries."

Remarkably, between the years 1850 and 2000, atmospheric carbon dioxide levels did increase by very close to 25 percent, and global average surface temperatures also increased by just about 0.6°C during that time.Sawyer also discussed several other important aspects of the Earth's climate in his paper. For example, he addressed the myth and misunderstanding that as a trace gas in the atmosphere, it may seem natural to assume that rising levels of carbon dioxide don't have much impact on the climate. Sawyer wrote,

"Nevertheless, there are certain minor constituents of the atmosphere which have a particularly significant effect in determining the world climate. They do this by their influence on the transmission of heat through the atmosphere by radiation. Carbon dioxide, water vapour and ozone all play such a role, and the quantities of these substances are not so much greater than the products of human endeavour that the possibilities of man-made influences may be dismissed out of hand."
