Seawater is proving to be one way to combat climate change by reducing fossil fuel dependency for some ocean island nations. Taking a page from land-based geothermal power which uses the coolness below ground in heat exchange systems, islands are using the thermal energy gradient in a column of seawater to generate electricity.
Last week, the IPCC gave us its weather forecast for climate change through the rest of the century. This weekend, the contributing scientists gave us what should be marching orders.
April 12, 2014 - There are two types of solar renewable technologies. The first, solar photovoltaics, is at best marginally efficient when converting energy from sunlight into electricity. And when the sun is not shining...well you get it. The second, solar thermal involves putting mirrors on motors to track sunlight.

A new study opens with the following statement: "Carbon release due to permafrost thaw represents a potentially major positive climate change feedback." I can just see climate change skeptics jumping on the words "positive climate change" thinking that this is no doubt a good thing.
With atmospheric temperatures creeping upward from the tropics to the poles, air conditioning in dwellings and workplaces will be in great demand. The estimate from the Intergovernmental Panel on Climate Change states we will see a rise in energy demand around air conditioning from 300 Terawatt-hours in 2000 to 4,000 Terawatt-hours by 2050. Increased energy demand, of course, has implications for greenhouse gas emissions.
The Great Dying happened 252 million years ago. This mass extinction event at the end of the Permian wiped out 90% of life on Earth. What caused it?
There are lots of theories.
The University of Puerto Rico at Arecibo is keeping a catalog of habitable exoplanets, planets that sit within the Goldilocks Zone surrounding a star. The image below illustrates the relative position of Goldilocks Zones around three different star types.
Over time, we integrated the Canadian and American grid to allow power generators to sell their products wherever electricity was needed. Today, this is the system we have here in North America, and it has its problems.
While traveling south to Florida this year, my wife and I reached Southern Kentucky where highway signs told us we were entering a fog zone that extended all the way into Northern Tennessee. This was no ordinary fog. It was pulp and paper fog, produced by the many mills that dot the mountainous and forested areas of these states.
