Discovery Of Massive Volcanic CO2 Emissions Puts Damper On Global Warming Theory

by J.E. Kamis, November 6, 2018 in ClimateChangeDispatch

Recent research shows that the volume of volcanic CO2 currently being emitted into Earth’s atmosphere is far greater than previously calculated, challenging the validity of the man-made global warming theory.

he cornerstone principle of the global warming theory, anthropogenic global warming (AGW), is built on the premise that significant increases of modern era human-induced CO2 emissions have acted to unnaturally warm Earth’s atmosphere.

A warmed atmosphere that directly, or in some cases indirectly fuels anomalous environmental disasters such as ocean warming, alteration of ocean chemistry, polar ice sheet melting, global sea level rise, coral bleaching and most importantly dramatic changes in climate.

There are numerous major problems with the AGW principle.

Identification of Volcanic vs. Man-made CO2

Solar forcing and climate variability during the past millennium as recorded in a high altitude lake: Lake Salda (SW Anatolia)

by I.B. Bauhi & S. Akçer-Ön, August 30, 2018 in QuaternaryInternational


Climate variability is a well-known phenomenon and has been frequently, though complex, linked to solar forcing on different time scales. The importance of solar forcing related climate variability is crucial in our understanding of paleoclimate and future climate changes, as well as building climate models. Here in, we present the late Holocene (last ca 1400) climate records from Lake Salda in SW Anatolia using high-resolution micro X-ray Fluorescence (μ-XRF), magnetic susceptibility (MS), stable isotopes13C and δ18O) and TOC-TIC measurements. The age model is constructed by using radionuclide (210Pb, 137Cs and 14C) dating methods. The lake’s high-resolution multiproxy results revealed lake water level fluctuations associated with humid and dry spells during the last 1400 years. Periods of higher lake levels are consistent with solar maxima in total solar irradiance and vice versa. Moreover, the Lake Salda records clearly show dry Dark Ages Cold Period (DACP), humid Medieval Climatic Anomaly (MCA), dry Little Ice Age (LIA), and humid Modern Warm Period (MoWP). These records suggest that the solar forcing, through its influence on the atmospheric circulation, is the main mechanism of climate change during the DACP, MCA, LIA and MoWP in this region.

The Economics of the IPCC’s Special Report on Limiting Temperatures to 1.5 °C

by Ken B. Gregory, P. Eng., October 31, 2018 in FriendsofScience

The Intergovernmental Panel on Climate Change (IPCC) published a special report (hereafter called SR15) on the impacts of global warming of 1.5 °C above pre-industrial levels on October 8, 2018. The report says the cost of mitigating CO2 emissions in 2030 to prevent temperatures from exceeding 1.5 °C above pre-industrial levels is about 880 US$2010 per tonne of CO2 ($/tCO2). The benefit of doing so, according to the report, is 15 $/tCO2. Using a climate sensitivity based on observations including effects of natural climate change, urban warming and the best available economic model, the mitigation proposal will prevent a benefit of 8.2 $/t CO2, for a total loss of 888 $/tCO2 mitigated. In other words, each $1000 spent on mitigation of CO2 emissions will cause another loss $9.20.

The SR15, presents various emissions pathways to limit the projected rise of temperatures from pre- industrial times, estimated to be the temperature average from 1850 to 1900, to the year 2100, and to limit the temperature rise to 2.0 °C by 2100. According to the IPCC, temperatures have increased by about 1.0 °C from pre-industrial times to 2017. Therefore, the emissions pathways to limit warming allows only 0.5 °C temperature rise from 2017, assuming there is no natural caused climate change.
