Temperature hasn’t risen in 20 years: latest data

(h/t Jason) Recently published data from independent meteorologists Dr Ryan Maue of WeatherBELL Analytics and Dr Roy Spencer show that global temperatures have fallen back to about the levels of 20 years ago.

The two scientists use different data sources – one terrestrial, the other from satellites – so the convergence of their findings is particularly significant.

WeatherBELL is a commercial forecaster using land-based climate data and specialises in providing long and short-term forecasts for the agriculture, energy, hydrology, retail and aviation industries. It has its own computer models but also accesses information from both the American NOAA and Britain’s Met Office.

According to Dr Maue, global temperatures dropped 0.5 degrees Celsius in April. In the northern hemisphere, they plunged a massive one degree. The Global Warming Policy Foundation commented: “As the record 2015–16 El Niño levels off, the global-warming hiatus is back with a vengeance.”

Dr Maue said the fall in temperatures (in degrees Celsius) over the past year are seen in the following variations from the 1981–2010 average:

March 2016     +0.673
April 2016       +0.557
March 2017     +0.558
April 2017       +0.375

The explanation of the temperature pause since 1998 – which contradicts the computer models used by the Intergovernmental Panel on Climate Change (IPCC) – has been the subject of widespread discussion in academic journals, including the American Geophysical Union journal, Geophysical Research Letters, as well as Climate Dynamics, and the Scientific Report of the Chinese Academy of Sciences. All agree that temperature rises have stalled, but there is no consensus on the cause.

Dr Roy Spencer publishes every month the average global temperature derived from satellite observations. Since 1979, satellites have been sending back to earth data on the temperature of the lower atmosphere, and this data is published by the University of Alabama, Huntsville (UAH) and on Dr Spencer’s website.

The satellite data indicates that average temperatures in April 2017 were 0.27 degrees above the 30-year average from 1981–2010. In the previous month, the data showed that the temperature was just 0.19 degrees above the 30-year average. The IPCC had forecast temperature variations five to 10 times as large.

The UAH chart for the entire period shows that in the 1990s, temperatures remained relatively steady until the large El Niño of 1997–98, and then oscillated around a new higher level until the El Niño of 2015–06, when it rose again, before falling back towards the 30-year average.

Another recent source of climate alarm has been the appearance of a large crack on the Larsen C ice shelf of the Antarctic Peninsula, which stretches up towards the tip of South America (News Weekly, March 11, 2017).

The ice-shelf is fed by several glaciers, which flow into the sea.

The splitting off of ice-shelves is an entirely natural phenomenon and is the cause of icebergs, which are common around Antarctica and, historically, have been observed as far north as New Zealand’s South Island. The most recent media report of icebergs being seen off the coast of New Zealand was in 2016. Previously, they had been reported in 2009 and 2006.

Calving of the Larsen C ice shelf would be the largest recent iceberg to break off from Antarctica, prompting claims that it is caused by global warming or “climate change”.

However, the overall area of sea ice around Antarctica is close to normal for this time of year, and recent research indicates that temperatures on the Antarctic Peninsula have fallen slightly in recent decades.

    Did you even talk to Dr Maue about this, Its true the temps did fall off, but April was still a top 5 warm month against April and May is likely to finish at 2cnd. The fact is the big fall off is because it was so warm that we went from consistent record highs to just plain warm. If you actually look at the running means, the fall off behind this el nino has not been impressive at all and one could argue may be establishing another plateau, higher than the past 20 years, as the last super nino did. This is not me coming to the “dark side” of co2 hysteria its merely stating that you use a snapshot and did not talk to either of the people about the conclusion you draw. Weather and climate are a movie not a snapshot, and a bigger picture reveals that its still not conclusive that the super nino is not signalling another jump to a new plateau a bit higher than the last one, but certainly not any of the catastrophic ideas that the AGW agenda has http://models.weatherbell.com/climate/cfsr_t2m_2005.png

    bottom line, talk to Dr Maue and Dr Spencer

    If you realy botjered to listen to Al Gore,David Suzuki,Leonardo DiCaprio or Luarie David and beleived all their malarkey you would beleive the earth was flat like the nuts from the Flat Earth Society do and were on the 11th Hour(DiCaprio’s fake documentry)and soon the earth will look like it did in the putrid Kevin Cosner movie WATERWORLD where he swims dolphin style and looks like a total baffoon
