1. The Amazon is drying
Since 2000, rainfall has decreased by up to 25% across a vast swath of the southeastern Amazon, according to a new satellite analysis.
The area of concern is 12 times the size of California. The Amazon overall takes up 25% of the global carbon cycle that vegetation is responsible for, so it’s a significant carbon sink. With further drying the Amazon could become a carbon source rather than a sink.
Causes are not clear, but it’s possible that rainfall patterns have moved further north with global warming.
In related news, the re-election of Dilma Rousseff as president is seen as a significant negative for the environment in Brazil.
In its formal response to the Reef 2050 long-term sustainability plan, which was drawn up by the Australian and Queensland governments, the Australian Academy of Science states the strategy is “inadequate to achieve the goal of restoring or even maintaining the diminished outstanding universal value of the reef.”
There is “no adequate recognition” in the 2050 plan of the importance of curbing greenhouse gases.
Professor Terry Hughes, director of the Australian Research Council Center of Excellence for Coral Reef Studies and an academy fellow, said the plan was focused on the sustainable development of four “mega ports” adjacent to the reef, rather than conservation of the reef itself.
The Great Barrier Reef has lost around half its coral cover in the past 30 years. The question now is whether UNESCO will list the GBR as endangered.
3. Limiting global warming to 2°C is unlikely to save most coral reefs
In this recent post I mentioned that “preserving more than 10 per cent of coral reefs worldwide would require limiting warming to below +1.5°C (atmosphere–ocean general circulation models (AOGCMs) range: 1.3–1.8°C) relative to pre-industrial levels”. Following the links, the paper by K. Frieler at al is here.
It annoys me that the dangers to reefs from temperature change and ocean acidification are almost never mentioned, even by greenies. Opposition pollies should be speaking up too! That paper has been around since 2011.
The government has cut almost half a billion dollars from research into carbon capture and storage – which the Intergovernmental Panel on Climate Change (IPCC) deems crucial for continued use of coal – despite the prime minister insisting coal is the “foundation of our prosperity”.
In the budget the government cut $459.3m over three years from its carbon capture and storage flagship program, leaving $191.7m to continue existing projects for the next seven years. The program had already been cut by the previous Labor government and much of the funding remained unallocated.
John Connor, the chief executive of the Climate Institute, said CCS “has to be one of the clean energy options available because all the modelling says that to avoid temperature rises of more than two degrees, we have to take carbon dioxide out of the atmosphere”.
The first full-scale CCS power plant, the Boundary Dam Carbon Capture and Storage Project in Canada, opened last month.
Poland and a bunch of eastern Europe countries “have categorically rejected the target put forward by the world’s top climate scientists to reduce carbon emissions to zero by 2100 to avoid dangerous global warming…”
You might recall that when Poland hosted the UNFCCC Conference of Parties in 2013 it was positively promoting coal.
The EU has not yet apportioned the effort between countries in planning to meet recently announced emissions reduction targets. The fun is about to begin!
6. Roof top solar in San Francisco
New regulations in San Francisco will require new buildings to have roof top solar or gardens or both.
7. Tesla solar supercharging network
Tesla is rolling out a solar supercharging network for electric vehicles throughout the world eventually. Soon they will make a beginning in Australia.
The superchargers provide half a full charge in as little as 20 minutes, and are usually located near amenities like roadside restaurants, cafes, and shopping centers. Usually they have between 4 and 10 stalls.
The $5 billion “giagfactory” to be built in Nevada will generate more than 100% of its electricity needs with wind and solar.
The world is changing!
8. News of energy storage is a big, big deal
So says Sophie Vorrath at RenewEconomy:
The big announcements keep coming from the energy storage sector, with news this week that US behind-the-meter startup, Stem, has been tapped to provide 85MW of distributed energy storage to households in the West Los Angeles Basin.
The deal, a multi-year agreement awarded to Stem by Southern California Edison (SCE), marks America’s largest distributed energy storage project to date, and the first time energy storage has competed with traditional energy sources like natural gas at this scale.
For its part of the deal, Stem will deploy its advanced, behind-the-meter energy storage technology at customer locations in the Western LA Basin to act as dispatchable capacity to enhance the local reliability of the region.
In other words, using the combination of storage and its proprietary software platform, Stem will allow customers to monitor and manage energy use, which in turn will provide additional capacity to SCE.
9. Billboard banned
You may have heard that Brisbane Airport banned a billboard suggesting to incoming G20 delegates that climate change should be on their agenda. Apparently the billboard was “too political”.
Getup and a bunch of other NGOs are campaigning to have the decision reversed.
The billboard was based on the experience of South Australian grape grower David Bruer, a farmer from South Australia who lost $25,000 worth of grapes in one day when temperatures soared to 45°C last year.
