Geographical distributions of penguin species
People of color support environmental protection at higher rates than whites. Yet, while people of color make up 36% of the US population, and 29% of the science and engineering workforce, they are substantially underrepresented on the staff of major environmental government agencies, NGOs, and the foundations that fund them. For the environmental movement to be effective in the future, it will need to become more diverse.
“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
Glacier area on Mount Kilimanjaro on the Kenya/Tanzania border in East Africa decreased 85% 1912-2007; from 12.06km2 to 1.85km2. While the loss of glaciers in temperate regions (such as those in the U.S.) has been attributed to warming temperatures from climate change, glacier loss on Kilimanjaro is more likely a result of a local climate change in East Africa that occurred in the late 1800s, resulting in a drier climate. However, causes of the dramatic glacier loss remain largely unknown.

While deforestation is a major source of global carbon emissions (see previous two posts), the expansion of agriculture into drained organic soils also releases carbon. Wetlands, and especially peatlands, have waterlogged soils. As a result, their soils are depleted of oxygen, preventing decomposition. This means that the carbon in plants and animals is stored in the soils. When these soils are drained, the oxygen returns and organic material decomposes. Decompostion releases the carbon stored in that material. Thus, draining wetland soils releases carbon dioxide and contributes to climate change.
FAO adds emissions from cropland expansion into drained organic soils to deforestation. The result: significant increases in carbon emissions from Indonesia, which has substantial peatlands.
Even as global carbon dioxide emissions hit a record high in 2012, CO2 emissions from energy generation in the United States fell to 1994 levels. This is a 13% decrease over the past 5 years. President Barack Obama has set a climate goal of lowering greenhouse gas emissions 17% from 2005 levels over the next decade. By the end of last year, levels were down 10.7% from the 2005 baseline, meaning America is more than halfway towards that goal.
The reductions come from a variety of places. It is, in part, because of new energy-saving technologies. In part because of a weakened economy. In part because of a growing share of renewables in the energy sector. And in part because cleaner natural gas is displacing carbon-rich coal.
While this is good news, there are some important caveats. 1.) This is only the U.S. Emissions are rising rapidly in other parts of the world. 2.) This is only CO2 emissions from energy production. This is a big source of greenhouse gas emissions, but not the only one. 3.) This rate of decline is probably not fast enough to avert the worst of climate change.
“Employment in the U.S. solar business grew 12 times faster than overall job creation... Fed by state initiatives to spur clean energy and innovative financing measures offered by companies such as SolarCity Corp., developers are adding workers at record rates to install rooftop panels. Oil and gas producers by contrast have slashed 351,410 jobs worldwide since prices began to slide in the middle of 2014, according to Houston-based Graves & Co.... This increase is being driven by declining renewable energy technology costs and enabling policy frameworks. We expect this to continue as the case for renewables strengthens and countries move to achieve climate targets... The group projects the workforce in clean energy will grow to 24 million by 2030 if United Nations targets are met on climate change and development.” - Bloomberg
