The Politicization of Climate Science Is NOT a Recent Phenomenon

Bob Tisdale - Climate Observations

There’s lots of yacking around the blogosphere and mainstream media about President-elect Donald Trump politicizing climate science. But it’s nothing new. Climate science became a tool for pushing political agendas almost 3 decades ago.

In 1988, the United Nations, a political body, founded the global-warming-report-writing entity called the Intergovernmental Panel on Climate Change (IPCC). The IPCC was created to support political agendas. And in 1995, politics corrupted climate science, when politicians changed the language of the IPCC’s second assessment report, eliminating the scientists’ statements of uncertainties.  To this day, the climate science community still cannot truly differentiate between natural and anthropogenic global warming.  Why?  The climate models used in attribution studies still cannot simulate modes of natural variability that can cause global warming over multidecadal timeframes.

The Bray (Hallstatt) Cycle

Watts Up With That?

Guest essay by Andy May and Javier

The evidence for a persistent irregular climate cycle with a period of 2400 ±200 years is strong. There is compelling evidence of a solar cycle of about the same length and phase; suggesting that the solar cycle might be causing the climate cycle. We will present a summary of the evidence, beginning with the original paleontological evidence, followed by the cosmogenic radionuclide (10Be or Beryllium-10 and 14C or Carbon-14) evidence. For more information, a bibliography of many papers discussing topics relevant to the Bray (Hallstatt) cycle can be found here. Only a small portion of the relevant papers are mentioned in this summary post.

In the November 16, 1968 issue of Nature, James R. Bray first proposed the idea of a 2600-year solar-driven climate cycle based primarily upon evidence of Holocene global glacier advances and retreats. We prefer…

Study: Earth’s vegetation is causing a global “pause” in CO2 growth

Watts Up With That?

From the DOE/LAWRENCE BERKELEY NATIONAL LABORATORY and the Department of Hungry Biomass comes this encouraging news that throws cold water on climate alarmism.

Study: Carbon-hungry plants impede growth rate of atmospheric CO2 

New findings suggest the rate at which CO2 is accumulating in the atmosphere has plateaued in recent years because Earth’s vegetation is grabbing more carbon from the air than in previous decades.

That’s the conclusion of a new multi-institutional study led by a scientist from the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). It’s based on extensive ground and atmospheric observations of CO2, satellite measurements of vegetation, and computer modeling. The research is published online Nov. 8 in the journal Nature Communications.

To be clear, human activity continues to emit increasing amounts of carbon, and the atmospheric concentration of CO2, now at 400 parts per million (ppm), continues to rise. But the scientists found that…

NOAA: U.S. Tornadoes lowest since 1954 – during the “hottest year ever”

Watts Up With That?

Latest data from NOAA’s Storm Prediction Center indicate that as of today, the total count for 2016 of US tornadoes are fewest in a calendar year since record-keeping began in 1954. That’s a hard fact, that flies in the face of claims of extreme weather being enhanced by warmer temperatures,  as many have tried to claim. This graph from NOAA SPC shows that with 830 tornadoes so far this year (in black), it has crossed the minimum line (in magenta) showing 879 as the previous lowest number recorded on this date.

Additionally, the National Weather Service Forecast Office in Nashville said today:

There have only been 5 tornadoes in Tennessee this year. It’s been the quietest year for tornadoes in the state since 1987.

Meanwhile the U.N.’s weather bureau is warning of this:

It is very likely that 2016 will be the hottest year on record, with global…

Finding: Forest fires in Sierra Nevada driven by past land use – not climate

Watts Up With That?

From the University of Arizona and Penn State comes this inconvenient finding.

Forest fire activity in California’s Sierra Nevada since 1600 has been influenced more by how humans used the land than by climate, according to new research led by University of Arizona and Penn State scientists.

For the years 1600 to 2015, the team found four periods, each lasting at least 55 years, where the frequency and extent of forest fires clearly differed from the time period before or after.

However, the shifts from one fire regime to another did not correspond to changes in temperature or moisture or other climate patterns until temperatures started rising in the 1980s.

“We were expecting to find climatic drivers,” said lead co-author Valerie Trouet, a UA associate professor…
