IPCC Groupthink trumped science

“In 1988, thanks to their efforts, the Intergovernmental Panel on Climate Change (IPCC) held its inaugural meeting. It was sold to the world as an impartial body of scientists but it was never any such thing. Right from the start it had a political purpose which trumped any scientific one: to assert the existence of man-made climate change and to urge dramatic, concerted action to stop it.” click here

Refutation of false claims concerning climate change

Misleading and incorrect claims continue to be made with regard to climate change. The claims below have long been shown to be incorrect yet they are still made. The most recent rebuttal to the claims below is here.

False Claim #1: Heat waves are increasing at an alarming rate and heat kills.

False Claim #2: Global warming is causing more hurricanes and stronger hurricanes.

False Claim #3: Global warming is causing more and stronger tornadoes.

False Claim #4: Global warming is increasing the magnitude and frequency of droughts and floods.

False Claim #5: Global Warming has increased U.S. Wildfires.

False Claim #6: Global warming is causing snow to disappear.

False Claim #7: Global warming is resulting in rising sea levels as seen in both tide gauge and satellite technology.

False Claim #8: Arctic, Antarctic and Greenland ice loss is accelerating due to global warming.

False Claim #9: Rising atmospheric CO2 concentrations are causing ocean acidification, which is catastrophically harming marine life.

False Claim #10: Carbon pollution is a health hazard.

The Politically Incorrect Guide to Climate Change

Deforestation increases surface temperatures

Gregory Duveiller, Josh Hooker, Alessandro Cescatti. The mark of vegetation change on Earth’s surface energy balance, Nature Communications, volume 9, 679, 2018 doi:10.1038/s41467-017-02810-8

Changing vegetation cover alters the radiative and non-radiative properties of the surface. The result of competing biophysical processes on Earth’s surface energy balance varies spatially and seasonally, and can lead to warming or cooling depending on the specific vegetation change and background climate. Here we provide the first data-driven assessment of the potential effect on the full surface energy balance of multiple vegetation transitions at global scale. For this purpose we developed a novel methodology that is optimized to disentangle the effect of mixed vegetation cover on the surface climate. We show that perturbations in the surface energy balance generated by vegetation change from 2000 to 2015 have led to an average increase of 0.23 ± 0.03 °C in local surface temperature where those vegetation changes occurred. Vegetation transitions behind this warming effect mainly relate to agricultural expansion in the tropics, where surface brightening and consequent reduction of net radiation does not counter-balance the increase in temperature associated with reduction in transpiration. This assessment will help the evaluation of land-based climate change mitigation plans.

House hold electrocoagulation filtration process produces potable water

Dhadge VL, Medhi CR, Changmai M, Purkait MK. House hold unit for the treatment of fluoride, iron, arsenic and microorganism contaminated drinking water. Chemosphere 2018 Feb 16;199:728-736. doi: 10.1016/j.chemosphere.2018.02.087.

A first of its kind hybrid electrocoagulation-filtration prototype unit was fabricated for the removal of fluoride, iron, arsenic and microorganisms contaminated drinking water. The unit comprised of 3 chambers, chamber A consisting of an inlet for the water to be treated and an outlet for the treated water along with one block of aluminum electrodes. Chamber B consisted of ceramic membrane filtration assembly at the bottom over a metallic support which filters the flocs so produced in chamber A and chamber C consisting of space to collect the treated water. Operating parameters were maintained as current density of 625 A m-2 and an electrode distance of 0.005 m. Contaminated drinking water containing mixture of fluoride (10 mg L-1), iron (25 mg L-1), arsenic (200 μg L-1) and microorganisms (35 CFU ml-1) was used for the experiment. A removal of 98.74%, 95.65%, 93.2% and 100% were obtained for iron, arsenic, fluoride and microorganisms, respectively. The apparatus and method made it possible to efficiently treat contaminated drinking water to produce drinkable water as per WHO specification. By-products obtained from the electrocoagulation bath were analyzed using SEM, EDX and XRD and explained.

China Responds to Electric Car Green Fraud

“The revamped subsidy program that took effect Monday grants automakers 24,000 yuan ($3,780) for each electric car with the typical range of 200km to 250km per charge, down from 36,000 yuan.” click here

 

Why Not Apply Occam’s Razor to Climate Modeling?

“A 1D forcing-feedback model with two equivalent-ocean layers is used to model monthly global average surface temperatures from 1880 through 2017. Reflected shortwave (SW) and thermally emitted longwave (LW) forcings and feedbacks are included in an attempt to obtain the closest match between the model and HadCRUT4 surface temperatures based upon correlation and long-term trends.” click here
