On The Two Year Anniversary Of The Deepwater Horizon Oil Spill In The Gulf Of Mexico, It's Worth Putting

On the two year anniversary of the Deepwater Horizon oil spill in the Gulf of Mexico, it's worth putting the size of that spill into context. By the time it was capped on July 15, 2010, the well had released 4.9 million barrels of oil into the Gulf, making it the largest accidental oil spill in history.

Graph Showing Carbon Dioxide Concentrations In The Atmosphere Over The Past 650,000 Years. Concentrations

Graph showing carbon dioxide concentrations in the atmosphere over the past 650,000 years. Concentrations are measured by examining trapped air bubbles in prehistoric ice cores. The graph shows current CO2 levels at an unprecedented high level in the atmosphere, far greater than during past natural climate cycles. A rapid increase is observed since the industrial revolution, highlighting the contribution of the burning of fossil fuels.

Acid Rain (wet Sulfate Deposition = Sulfuric Acid Rain) Before (89-91) And After (07-09) The Clean Air

Acid rain (wet sulfate deposition = sulfuric acid rain) before (89-91) and after (07-09) the Clean Air Act Amendments of 1990, which used a cap & trade program to limit sulfur dioxide emissions. For anyone who has any doubt that environmental regulations can work...

“[T]he Frequency Of Coal Retirements Highlights The Speed At Which The Nation’s Utilities Are Changing
“[T]he Frequency Of Coal Retirements Highlights The Speed At Which The Nation’s Utilities Are Changing

“[T]he frequency of coal retirements highlights the speed at which the nation’s utilities are changing the energy mix by replacing coal with natural gas and renewables, particularly wind. Few new coal plants are in the works to replace those that are being shut down...As a result of a confluence of factors, the coal industry’s decline has been a long time coming. The story of coal’s decline goes far beyond the false narrative that Trump and his EPA pick Scott Pruitt are advancing that points to EPA regulations as the sole reason for coal plant retirements.” - Devashree Saha and Sifan Liu

“Over The Past Year, Seven Of The Estimated 80 Remaining Texas Ocelots Were Killed By Vehicles. Six

“Over the past year, seven of the estimated 80 remaining Texas ocelots were killed by vehicles. Six of these mortalities were adult males. Among ocelots, it is not easy to be a maturing male. In order to prevent competition for access to breeding females, older males often force the younger males to leave the area where they grew up, sending them out to find females and territory of their own. Once out of protected, dense brush habitat areas, these younger males encounter the human-developed world and all of its dangers, in particular roads and vehicles. In reaction to the large proportion of road mortalities being males, Dr. Hilary Swarts, a wildlife biologist who monitors ocelots in south Texas with the U.S. Fish and Wildlife Service (USFWS) said, ‘I can’t say it’s surprising that six of the seven deaths were males, since they have such a rough time of it once the older males start to see the younger males as competition for mates and territory.’” - See more at: http://blog.cincinnatizoo.org/#sthash.YjGoogOC.dpuf

From mic.com:

This map traces the ideal deployment of solar energy plants in the Sahara Desert to generate electrical power for the world's population. It might not look like a lot, but there are some major caveats here. For one, this map seems to assume 100% efficiency. In reality, current solar panel technology is only able to capture around 20% of solar energy, even in the desert. So the 254-by-254 kilometer area in the Sahara Desert that could theoretically absorb enough rays to power the entire world would have to be five times larger. Second, large amounts of electric power are lost over large transmission distances, meaning that a single power plant could never really power the entire planet.

Still, this map is a good illustration of how little space would be needed to power the entire planet. According to May, some 3.49 million square kilometers are available for solar thermal power facilities in Morocco, Algeria, Tunisia, Libya and Egypt alone. Worldwide, the potential high-energy solar sites far outstrip any plausible need.
