If we stop killing parrotfish we can bring back Caribbean coral reefs
Eureka Alert, July 2, 2014: Gland, Switzerland – With only about one-sixth of the original coral cover left, most Caribbean coral reefs may disappear in the next 20 years, primarily due to the loss of grazers in the region. The Caribbean corals have declined by more than 50% since the 1970s. But according to the authors, restoring parrotfish populations and improving other management strategies, such as protection from overfishing and excessive coastal pollution, could help the reefs recover and make them more resilient to future climate change impacts.
"The fate of Caribbean corals is not beyond our control and there are some very concrete steps that we can take to help them recover," says Carl Gustaf Lundin, Director of IUCN's Global Marine and Polar Programme. Full story here.
Putting a price tag on the 2° climate target
July 2, 2014 - Addressing climate change will require substantial new investment in low-carbon energy and energy efficiency – but no more than what is currently spent on today’s fossil-dominated energy system, according to new research from IIASA and partners.
To limit climate change to 2° Celsius, low-carbon energy options will need additional investments of about US $800 billion a year globally from now to mid-century, according to a new study published in the journal Climate Change Economics. But much of that capital could come from shifting subsidies and investments away from fossil fuels and associated technologies. Worldwide, fossil subsidies currently amount to around $500 billion per year.
“We know that if we want to avoid the worst impacts of climate change, we need to drastically transform our energy system,” says IIASA researcher David McCollum, who led the study. “This is a comprehensive analysis to show how much investment capital is needed to successfully make that transition.” Full story here.
