Marine Cloud Whitening: Best Solution to AGW?

By

WASHINGTON, DC – After deliberations into the best responses to global warming, an Expert Panel of five top economists including three Nobel Laureates concluded that greater resources should be spent on research into climate engineering and green energy.

The Expert Panel’s findings highlight the problems with the current political focus on carbon taxes, and underscore the vast promise shown by alternative responses to global warming.

The Expert Panel scrutinized 21 ground-breaking research papers by top climate economists that analyzed the costs and benefits of different responses to global warming, ranging from a focus on black carbon mitigation to climate engineering and varying levels of carbon taxes. Based on an analysis of the new research, they created a prioritized list (overleaf) that outlines the best and worst ways to respond to climate change.

The Expert Panel concluded that the most effective use of resources would be to invest immediately in researching marine cloud whitening technology (where boats spray seawater droplets into clouds above the sea to make them reflect more sunlight back into space, reducing warming).  [Read more…] about Marine Cloud Whitening: Best Solution to AGW?

Academics and Freedom of Speech

By

EVERY so often I receive emails suggesting I am morally reprehensible.  Interesting, like the following email, they often follow a function at an Australian university.  

Hi there,

I attended a very interesting lecture today around Climate change denialism with guest speakers Dr Andrew Glikson of the Planetry Science Institute and Professor Clive Hamilton of the ANU [Australian National University].
 
It seems to me there is a vast array of eminent scientists who are in agreement that increased levels of carbon due to human activity is having an undeniable impact on global warming.

More on Californian Bushfires

“I moved from San Francisco to the LA area about a month ago so am experiencing the fires from a little closer vicinity. The local news
told us that the areas on fire last burnt about 1929! The brush is 20ft high in many places! After a week of burning they finally pulled
in the larger drop aircraft including the DC-10.” Vernon.

Defining the Scientific Sceptics (Part 10): Karl Popper

By

The genuine rationalist does not think that he or anyone else is in possession of the truth; nor does he think that mere criticism as such helps us achieve new ideas. But he does think that, in the sphere of ideas, only critical discussion can help us sort the wheat from the chaff. He is well aware that acceptance or rejection of an idea is never a purely rational matter; but he thinks that only critical discussion can give us the maturity to see an idea from more and more sides and to make a correct judgement of it.

Record Warm Sea Surface Temperatures

By

Sea Surface Temperatures Spencer v2SCIENTISTS at the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center (CPC) recently announced that the average global sea surface temperatures in July was 62.6 degrees F making it hotter than the previous record of 1998 and the hottest since record-keeping began in 1880.

The record average is from satellite based measurements and was initially disputed by some sceptics including climate scientists Roy Spencer, University of Alabama, Huntsville. Dr Spencer initially attributed the error to a data processing blunder at NOAA, but has since conceded the blunder in the calculations was his.   [Read more…] about Record Warm Sea Surface Temperatures
