Early September 2017 Saw Wildfires Raging Through The American West.

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.

The reduction in CO2 emissions from the energy sector in the U.S. over the past 5 years (see previous post) was due in large part to a reduction in emissions from coal. In 2009, the financial collapse led to diminished use of all fuel sources and greenhouse gas reductions across the board. Since then, the expanding use of natural gas has increased it's carbon footprint, but the decline in the use of coal and the subsequent decrease in greenhouse gas emissions associated with coal is remarkable. Coal is the most carbon-rich fossil fuel, so any declines from that source is good news for the climate.

In the U.S., clean energy and carbon pollution regulation are very popular. What is the disconnect between public opinion on these issues, and Federal actions?

According to the National Climatic Data Center, the average global temperature for 2012 made it the 10th warmest year on record since record keeping began in 1880. It also marked the 36th consecutive year with a global temperature above the 20th century average. The last below-average annual temperature was 1976.

The map shows 2012 temperatre anomalies, with red indicating higher than average temperatures and blue lower. Looking at the United States,2012 was the warmest year on record.

Sea Level Rise

For thousands of years, sea level has remained relatively stable. But now, Earth’s seas are rising. Since the beginning of the 20th century, they have risen about eight inches, and more than two inches in the last 20 years alone!

As water warms, it expands and takes up more space. That means that when oceans warm, the sea level rises. This summer, we’ve been researching exactly how global warming has impacted Greenland’s ice sheet. Our ICESat-2 mission will use a laser to measure the height of the planet’s surface. Over time, we will be able to provide a record of elevation change, and estimate how much water has melted into the ocean from land ice change.

So how much ice are we actually losing? Great question, but the answer might shock you. In Greenland alone, 303 gigatons of ice was lost in 2014!

Since we know that ice is melting, we’re working to gain a better understanding of how much and how fast. We’re using everything from planes, probes and boats, to satellites and lasers to determine the impact of global warming on the Earth’s ice.

Per capita CO2 emissions in Europe

44% of crocodilians are threatened according to the IUCN. The Chinese alligator, Orinoco crocodile, Phillippines crocodile, Cuban crocodile, Siamese crocodile and Gharial are all considered critically endangered. A conservation success story, the American alligator, once facing extinction, is now considered "low risk", although the American crocodile is "vulnerable".

“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

Wetlands losses and gains for different land use categories. While, historically, agriculture was responsible for the vast majority of wetlands losses, government incentive programs like the Wetlands Reserve Program have encouraged farmers to restore former wetlands on their lands, contributing to a net gain of wetlands from the agriculture sector 2004-2009. In contrast, silviculture (forestry) is contributing heavily to wetlands losses, with urban and rural development also destroying wetlands. Urban and rural development combined accounted for 23 percent of the wetland losses 2004-2009, while silviculture accounted for 56% (a decrease from 1998-2004 for urban and rural development and an increase for silviculture).

*"Other" included areas such as native prairie, un-managed forests, scrub lands, barren and abandoned land, lands enrolled in conservation easements or other lands designated as wildlife management areas. Conservation programs are largely responsible for high wetlands gains from these areas.
