July 4, 2017 : Coldest July Temperature Ever Recorded In The Northern Hemisphere



Study Finds Temperature Adjustments Account For ‘Nearly All Of The Warming’ In Climate Data

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 [global average surface temperature (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.

The peer-reviewed study tried to validate current surface temperature datasets managed by NASA, NOAA and the UK’s Met Office, all of which make adjustments to raw thermometer readings. Skeptics of man-made global warming have criticized the adjustments.

Climate scientists often apply adjustments to surface temperature thermometers to account for “biases” in the data. The new study doesn’t question the adjustments themselves but notes nearly all of them increase the warming trend.

Basically, “cyclical pattern in the earlier reported data has very nearly been ‘adjusted’ out” of temperature readings taken from weather stations, buoys, ships and other sources.

Groups see climate science review as chance to undercut regulation

The move by the Environmental Protection Agency to launch public debates between scientists on climate research, known as red-team, blue-team exercises, would be the first major effort by the Republican administration to challenge the long-standing scientific consensus on human-caused climate change.

Advocates who have petitioned the EPA to reverse the scientific finding underlying U.S. regulations governing greenhouse gas emissions see the proposal to scrutinize mainstream climate science as a first step in that direction.

"It's a way to survey the landscape before reopening the endangerment finding," said Myron Ebell, head of the Competitive Enterprise Institute, one of the groups that filed a petition with the agency to undo the 2009 scientific determination that formed the basis for the Democratic Obama administration's regulation of greenhouse gases.

In 2007, the Supreme Court ruled that the EPA had authority under the federal Clean Air Act to regulate greenhouse gases from cars if the agency determined they endangered human health.

EPA Administrator Scott Pruitt has spoken several times about the merits of opening the climate change debate up to the public. The website Climatewire on Friday cited a senior administration official, who said Pruitt plans to launch the back-and-forth scientific critiques formally.

New Insights on the Physical Nature of the Atmospheric Greenhouse Effect Deduced from an Empirical Planetary Temperature Model

A key entailment from the model is that the atmospheric ‘greenhouse effect’ currently viewed as a radiative phenomenon is in fact an adiabatic (pressure-induced) thermal enhancement analogous to compression heating and independent of atmospheric composition. Consequently, the global down-welling long-wave flux presently assumed to drive Earth’s surface warming appears to be a product of the air temperature set by solar heating and atmospheric pressure. In other words, the so-called ‘greenhouse back radiation’ is globally a result of the atmospheric thermal effect rather than a cause for it. Our empirical model has also fundamental implications for the role of oceans, water vapor, and planetary albedo in global climate. Since produced by a rigorous attempt to describe planetary temperatures in the context of a cosmic continuum using an objective analysis of vetted observations from across the Solar System, these findings call for a paradigm shift in our understanding of the atmospheric ‘greenhouse effect’ as a fundamental property of climate.
