Green Energy On Mars

Photo Credit: NASA / JPL-Caltech / Cornell / ASU / S. Atkinson
This photograph was made possible by green energy.  The rover Opportunity has been on Mars for almost 9 years and it is still roving, taking pictures, drilling and dusting off rocks solely on solar energy.  Mars gets far less solar energy than does the Earth.   If we can run a spacecraft in the hostile environment of Mars for 9 years solely on solar energy why can't the United States transfer to a Green Energy platform and why would we want to?   One of the primary reasons for moving our economy off oil and onto wind and solar is economics.  Trillions of US dollars are sent offshore every year to places that mostly don't like us and have a history of instability.  After the BP Deepwater disaster in the Gulf of Mexico during 2010 everyone is aware of the extreme costs and environmental damage commensurate with oil economies.  The world is slowly waking up to the unbelievable costs associated with emitting large quantities of CO2 into the atmosphere, leading to rising sea levels, stronger storms and droughts. 
Millions of jobs will be created building solar and wind energy farms.  Thousands more will be created upgrading our electrical grid to move the available electrical energy across our continent.  Lets go green

Aurora Alert Tonight

Image from Wikipedia
The sun released a huge flare this morning.  It's expected to hit the earth's atmosphere on March 8th at 0625 UT + or - 7 hours.  That's as early as tonight for Seattle viewers.  So check out the sky tonight, you might see a celestial show.  Here is a link to an incredible 3D forecast map of the CME prepared by NASA.
Here is a better 3D representation of the CME and its approach to Earth

Exposing the "Science" Behind Climate Change Deniers

On Ethan Siegel's Blog Starts With a Bang, he analyzes data from the BEST (Berkeley Earth Surface Temperature Project) which was supposed to settle the question is Global Climate Change occurring.  Strangely, this study was funded in part by the Koch brothers and Richard Muller who headed the project was a vigorous skeptic of climate change.  When the BEST study found that indeed, the data did show a warming trend many were surprised.  It was also amazing how closely the data from the BEST study correlated with NOAA, NASA and other studies. 
But there was one dissenter, Judith Curry the sole climatologist assigned to the study, disagreed and stated that the global warming trend had slowed and the data that Richard Muller presented in the  BEST results hid the decline.
"In Prof Curry’s view, two of the papers were not ready to be  published, in part because they did not properly address the arguments of climate sceptics.
As for the graph disseminated to the media, she said: ‘This is “hide the decline” stuff. Our data show the pause, just as the other sets of data do. Muller is hiding the decline.
‘To say this is the end of scepticism is misleading, as is the  statement that warming hasn’t paused. It is also misleading to say, as he has, that the issue of heat islands has been settled.’" [1.]
 It's a great read, and Ethan Siegel explains very clearly so it's easy to see how Prof. Curry manipulated the data to create what some are calling fraudulent claims.   You can find it here.
