Major climate change skeptic changes his mind

Posted: Updated:

Few subjects have been more controversial than global warming and climate change. Now, Richard Muller, professor of physics at University of California Berkeley one of the most outspoken opponents of global warming has reversed his opinion and is convinced that prior estimates regarding the rate of warming are indeed correct and that humans are almost entirely the cause of that warming".

Muller is the co-founder of the Berkeley Earth Surface Temperature team which independently assesses any questionable evidence of global warming.  Their analysis has now indicated that global warming is real and not a passing weather pattern. Furthermore they find that the average global land temperature has risen by 2.5 degrees F since 1750. 1.5 degrees F of that increase took place in the past 50 years. This finding is in line with past studies by the National Oceanic and Atmospheric Administration (NOAA), NASA and others.

Muller and his team at Berkeley have further established that blame from natural variations in Earth's climate is not possible and that carbon dioxide emissions by humans is essentially the sole cause of global warming.

The carbon dioxide curve depicted above closely follows the temperature trend since 1750 with the red line representing atmospheric concentration of CO2 almost perfectly overlaying the black line representing the observed warming of the Earth.

The study found that natural variability from solar cycles, El Niño, La Niña and shifts in the Atlantic sea surface temperatures only accounted for miniscule warming or cooling during the past 150 years and were not the cause of the more aggressive warming recorded.

    Scientists believe a cluster of devastating earthquakes could strike San Francisco in the next 18 years.In 1906 San Francisco was nearly flattened when a major earthquake struck the city. Since that time there have been only a handful of large quakes in that area and now scientists are predicting a 63 percent chance that a major earthquake or series of major quakes will strike the Bay Area before the year 2032. The findings were part of a recent report in the Bulletin of the Seismological Soc...
