Geologists uncover new clues about largest mass extinction ever

by University of Tennessee at Knoxville, August 27, 2018 in ScienceDaily from Nature.

Through the analysis of samples, Broadley and his team tried to determine the composition of the lithosphere. They found that before the Siberian Flood Basalts took place, the Siberian lithosphere was heavily loaded with chlorine, bromine, and iodine, all chemical elements from the halogen group. However, these elements seem to have disappeared after the volcanic eruption.

“We concluded that the large reservoir of halogens that was stored in the Siberian lithosphere was sent into the earth’s atmosphere during the volcanic explosion, effectively destroying the ozone layer at the time and contributing to the mass extinction,” Broadley said.

Scrutinizing the carbon cycle and CO2 residence time in the atmosphere

by H. Harde, May 2017 in GlobalPanetaryChange

•  We present a carbon cycle with an uptake proportional to the COconcentration.
• Temperature dependent natural emission and absorption rates are considered.
• The average residence time of CO2 in the atmosphere is found to be 4 years.
• Paleoclimatic CO2 variations and the actual CO2 growth rate are well reproduced.
• Human emissions only contribute 15 % to the CO2 increase over the Industrial Era.

Warmists Censor CO2-Climate Debate By Refusing To Publish Author’s Response To Attacks

by K. Richard, August 27, 2018 in ClimateChangeDispatch

A 2017 peer-reviewed paper authored by physicist Dr. Hermann Harde drew considerable response upon its publication in the journal Global and Planetary Change.

Harde’s conclusion that less than 15% of the increase in CO2 concentration since the 19th century could be attributed to anthropogenic emissions was deemed unacceptable by gatekeepers of the anthropogenic global warming (AGW) viewpoint.

A critical reply to the paper was consequently published, but it included assumptive errors and misrepresentations of the original points …

Germany’s retreat from Paris Climate Accord goals

Merkel says EU should meet existing emissions aims, not set new ones

A proliferation of extreme weather events around the world provides ample evidence that climate change is a reality, German Chancellor Angela Merkel said on Sunday, but she rejected calls for more ambitious climate protection goals.

But Merkel said such calls, most recently from the European Commission’s climate chief Miguel Arias Canete, for swifter cuts to harmful carbon dioxide emissions would be counterproductive, adding that setting new goals made little sense when European countries were already struggling to meet their cuts targets.

Why I Don’t Deny: Confessions of a Climate Skeptic — Part 2

by Kip Hansen, August 27, 2018 in WUWT

Note:  Please read Part 1 before reading this — this is a continuation of that essay (a rather long continuation….).

Readers will have heard the line “multiple lines of evidence” attached to the attribution of anthropogenic causes.  However, that phrase is used only once in AR5 SPM as “Multiple lines of evidence indicate a strong, consistent, almost linear relationship between cumulative CO2 emissions and projected global temperature change to the year 2100….”  I’m sure I don’t need to point out that there is never ever evidence about the future…..They do not claim in the Summary for Policy Makers that there are multiple lines of evidence for the attribution statement that apply to the past-to-present.
