Schwartz, S. E., R. J. Charlson, R. Kahn, and H. Rodhe (2014), Earth’s Climate Sensitivity: Apparent Inconsistencies in Recent Assessments, Earth’s Future, 2 601–605, doi:10.1002/2014EF000273.
Earth’s equilibrium climate sensitivity (ECS) and forcing of Earth’s climate system over the industrial era have been re-examined in two new assessments: the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC), and a study by Otto et al. (2013). The ranges of these quantities given in these assessments and also in the Fourth (2007) IPCC Assessment are analyzed here within the framework of a planetary energy balance model, taking into account the observed increase in global mean surface temperature over the instrumental record together with best estimates of the rate of increase of planetary heat content. This analysis shows systematic differences among the several assessments and apparent inconsistencies within individual assessments. Importantly, the likely range of ECS to doubled CO2 given in AR5, 1.5 – 4.5 K/(3.7 W m−2 ) exceeds the range inferred from the assessed likely range of forcing, 1.2–2.9 K/(3.7 W m−2), where 3.7 W m−2 denotes the forcing for doubled CO2. Such differences underscore the need to identify their causes and reduce the underlying uncertainties. Explanations might involve underestimated negative aerosol forcing, overestimated total forcing, overestimated climate sen- sitivity, poorly constrained ocean heating, limitations of the energy balance model, or a combination of effects.
Decide for yourself:
“Last November, Japan’s Environment Ministry issued a stark warning: the amount of solar panel waste Japan produces every year will rise from 10,000 to 800,000 tons by 2040, and the nation has no plan for safely disposing of it.”
“Neither does California, a world leader in deploying solar panels. Only Europe requires solar panel makers to collect and dispose of solar waste at the end of their lives.” click here for full post at WUWT
“As our article explains, this is all puffery and belief in tooth fairies. The issues and questions we raise ought to shame and embarrass WASI members – for spending countless billions of other people’s dollars to prevent an undetectable and irrelevant 0.01 degrees of global warming. We also ask whether jurisdictions within WASI states can take the “progressive” route and declare themselves sanctuary cities or counties, to protect their jobs and families against WASI dictates. Perhaps our article will persuade more Americans to make their voices heard, ask hard questions – and start resisting The Anti-Trump Resistance.” click here
A leadership change is needed at the AMS. The claim they are making about carbon dioxide is unsupported. Dogma such as this is counterproductive.
“Yesterday, the American Meteorological Society (AMS) sent a letter to DOE Secretary Rick Perry, scolding him for the following opinion he uttered in a CNBC interview on June 19.” click here
Days before Obama started claiming that Trump and Russia hacked the election, he said :
There is no serious person out there that would suggest somehow that you could even rig America’s elections.”
“The network President Donald Trump has identified as a “very fake news” outlet is under fire from all sides as it was forced to retract a blatantly inaccurate hit piece on President Trump and his associates in the wake of a Breitbart News investigation this weekend.” click here
