Bombshell study: Temperature Adjustments Account For ‘Nearly All Of The Warming’ In Government Climate Data

by Michael Bastasch, July 6, 2017, in WUWT

A new study found adjustments made to global surface temperature readings by scientists in recent years “are totally inconsistent with published and credible U.S. and other temperature data.”

“Thus, it is impossible to conclude from the three published GAST data sets that recent years have been the warmest ever – despite current claims of record setting warming,” according to a study published June 27 by two scientists and a veteran statistician.

Despite Paris accord, G-20 countries invest four times as much in fossil fuels as green energy

by Ben Wolfgang, July 5, 2017,  in The Washington Times

The biggest critics of President Trump’s decision to withdraw from the Paris climate accord are also the world’s biggest hypocrites on energy policy, top environmental groups charged Wednesday in a report that found many top nations’ rhetoric on cutting emissions doesn’t line up with how and where they spend their money.

The key finding: The G-20 nations spend roughly four times as much in public financing for fossil fuels as they do supporting renewable energy sources such as wind and solar. The report examines loans, grants, guarantees, insurance and other types of public finance offered either by the governments, government-owned financial institutions and credit agencies, and multilateral groups made up of G-20 countries.

On Sunday, Goulburn got colder than the BOM thought was possible (and a raw data record was “adjusted”)

by JoNova, July 2017

The BOM got caught this week auto-adjusting cold extremes to be less cold. Lance Pidgeon of the unofficial BOM audit team noticed that the thermometer at Goulburn airport recorded – 10.4°C at 6.17am on Sunday morning, but the official BOM climate records said it was -10.0°C. (What’s the point of that decimal place?) Either way this was a new record for Goulburn in July. (The previous  coldest ever July morning was -9.1°C. The oldest day in Goulburn was in August 1994 when it reached -10.9°C).

Coal Boom: 1600 new plants in 62 countries around the world – increasing 43%

by JoNova, July 2017

“End-Coal” Global Coal Tracker  does a magnificent job of showing how essential coal is around the world, and which countries are pathetically backwards in developing new coal plants. It’s probably not what the “CoalSwarm” team was hoping to achieve, but this map is a real asset to those of us who want to show how tiny Australia’s coal fired assets are compared to the rest of the world

Fungi are key players of the deep biosphere

by Linnaeus University, July 4, 2017

In addition to the life on the surface of the Earth and in its oceans, ecosystems have evolved deep under us in a realm coined the “deep biosphere” which stretches several kilometers down into the bedrock. Down there, the conditions are harsh and life is forced to adjust to a lifestyle that we at the surface would call extreme. One major difference to surface conditions is the lack of oxygen; a compound we take for granted and consider to be a prerequisite for survival but which subsurface life has to cope without.

Geologic forces fueling West Antarctica’s Larsen Ice Shelf Cracks

by James Kamis, July 4, 2017 in ClimateChangeDispatch

Geological heat flow is fueling bottom melting and associated cracks across West Antarctica’s Larsen Ice Shelf, having little to do with man-made global warming. Significant amounts of high-quality data and relevant geological observations support this revelation, given historical and current geological mapping efforts done in Antarctica.

Skillful prediction of northern climate provided by the ocean

by M. Arthur et al., June 20, 2017, in Nature Communication

We show that variations in ocean temperature in the high latitude North Atlantic and Nordic Seas are reflected in the climate of northwestern Europe and in winter Arctic sea ice extent. Statistical regression models show that a significant part of northern climate variability thus can be skillfully predicted up to a decade in advance based on the state of the ocean. Particularly, we predict that Norwegian air temperature will decrease over the coming years, although staying above the long-term (1981–2010) average. Winter Arctic sea ice extent will remain low but with a general increase towards 2020.

Pronounced differences between observed and CMIP5-simulated multidecadal climate variability in the twentieth century

by Sergey Kravtsov, June 15, 2017

The observed internal variability so estimated exhibits a pronounced multidecadal mode with a distinctive spatiotemporal signature, which is altogether absent in model simulations. This single mode explains a major fraction of model-data differences over the entire climate index network considered; it may reflect either biases in the models’ forced response or models’ lack of requisite internal dynamics, or a combination of both.

‘Perfect storm’ led to 2016 Great Barrier Reef bleaching

by James Cook University and Université Catholique de Louvain, July 3, 2017, in ScienceDaily

Professor Wolanski said the study was subjective to the extent that there was a lack of oceanographic field data in the Great Barrier Reef itself for the 2016 el Nino event. By contrast, the amount of oceanographic field data in the Torres Strait and the northern Coral Sea was very good.

“What we presented is our best-informed attempt to reveal the mechanisms involved in causing the event, based on the available oceanographic data combined with the existing body of knowledge on the water circulation in and around the Torres Strait/Northern Great Barrier Reef region.”

…Importance of CO2…

by Donn Dears, July 2017

Here is a summary of the graph’s salient points:

  • The CO2 safe limit for US Navy submarines is 8,000 ppm (Dotted red line)
  • The CO2 safe limit for the space station is 5,000 ppm (Dotted blue line)
  • A line depicting the gradual doubling of CO2 is near the bottom of the graph
  • The minimum atmospheric CO2 requirements to sustain plant growth is 150 ppm (Dotted green line)

In addition, atmospheric CO2 has been as high as 7,000 ppm approximately 550 million years ago, and as high as 2,000 ppm as recently as 150 million years ago. (Also here in French)

What the graph clearly shows is how close mankind came to extinction when atmospheric CO2 levels dropped to 183 ppm during the last ice age.

China Met Office Confirms Global Warming Hiatus

by Dr David Whitehouse, July 4, 2017 in GWPF

The China Meteorological Administration (CMA) has recently developed a new global monthly land-surface air temperature data set called CMA GLSAT. Using it researchers from the administration reanalysed the change in global annual mean land-surface air temperature during three time periods (1901–2014, 1979–2014 and 1998–2014) to see if there was any evidence of a hiatus or pause in recent surface global warming.

The researchers find very clear evidence for the recent warming hiatus. Their results show linear trends of 0.104 °C per decade, 0.247 °C per decade and 0.098 °C per decade for the three periods, respectively. The trends were statistically significant except for the period 1998–2014, the period that is also known as the ‘‘warming hiatus”.

Just When You Thought Scientists Couldn’t Possibly Get Any Stupider …

by Tony Heller, July 4, 2017

Venus is hot because it has an atmospheric pressure almost 100X that of Earth. The same reason why the top of the Grand canyon is cold, and the bottom of the Grand Canyon is hot. Temperatures in Venus troposphere at the elevation where pressure is 1 bar, are similar to earth.  Only a complete moron would believe that adding 0.0001 mole fraction CO2 to the atmosphere would cause that.
