Even As Global Carbon Dioxide Emissions Hit A Record High In 2012, CO2 Emissions From Energy Generation

Rhino poaching in South Africa decreased for the third year in a row, according to South African Minister of Water and Environmental Affairs, Edna Molewa. But the number is still unsustainably high, with about 3 rhinos killed per day in South Africa.

Rising incomes in Asian nations, such as Vietnam and China, is driving a renewed poaching boom for rhino horns, and poachers are finding new ways to avoid detection of exports.

Forest cover on Borneo over time, projected to 2020. Deforestation, driven mostly by clearing land to produce palm oil plantations, means less habitat for species such as orangutans, and more carbon emissions from disturbed peat lands.

The species groups that are proportionally most in danger (the proportion of species within that grouping that are imperiled) are overwhelmingly freshwater species. Freshwater mussels, crayfishes, stoneflies (stonefly larvae live in freshwater), freshwater fishes and amphibians are the most at risk. This demonstrates the substantial need for a focus on conservation of freshwater habitats.

A recent report from the Energy Information Administration found that U.S. plant owners and operators are getting ready to retire 27 gigawatts’ worth of coal generation, or about 8.5 percent of the coal fleet, between now and 2016. Considering the substantial contribution of burning coal to climate change, coal plant retirements are one of the greatest ways to reduce carbon emissions.

The sex of a sea turtle hatching is determined by temperature. Nests incubated at cooler temperatures produce more males, while nests incubated at warmer temperatures produce more females.

This could be a problem with climate change. As global temperatures rise, nests will be incubated at higher temperatures, producing fewer males. As this study found, climate change could lead to turtle nests with few to no males, skewing sex ratios and endangering the persistence of sea turtle populations. As the authors note:

“[O]nce incubation temperatures are 35°C, there are almost no more males produced (1 per 50 000 eggs laid)... As turtles return to the rough neighbourhood of their natal breeding grounds, it seems likely that for populations already producing more than 80% females, there will be a real extinction risk if they continue to nest at the same time of year and conditions warm by a few degrees.” 

But the bigger issue may be the increasing number of unviable eggs with rising temperatures. As the authors claim:

“[T]he primary concern in scenarios of climate change and rising incubation temperatures [is]... the high hatchling mortality in excessively warm nests...While climate warming still poses a threat to sea turtles, it is not the skewed sex ratios per se that will threaten population survival but rather higher mortality within clutches.”

Biodiversity hotspots around the world

In a report Tuesday, Environment and Climate Change Canada said the 51 separate herds [of boreal caribou] across the country remain under pressure from human and natural disturbances to their habitat more than five years after the federal and provincial governments concluded a protection agreement.

The range of the boreal caribou extends across the country from Yukon to Labrador, but its forest habitat has been increasingly disturbed by industrial activity such as forestry, mining and oil and gas development, as well as by forest fires, the spread of pests and other impacts of climate change.

Water stress in the Middle East and North Africa. Of the 16 nations worldwide suffering extreme water stress, all are in this region. Bahrain tops the list of those using far more water than they sustainably receive. In a region prone to conflict and civil unrest, and experiencing rapid population growth, water stress could fuel greater conflict.
