2015 Sets Record Investment in Renewables

  End of Oil-Age

Global investment in renewable energy hit a record US$285.9bn (£202.3bn) in 2015, beating the previous high of $278.5bn set in 2011, a study shows.

UN: 2015 Record Year for Global Renewables Investment

The 10th Global Trends in Renewable Energy Investment also showed that investment in developing nations exceeded that in developed countries.
In another first, more new renewables capacity than fossil-fuel generation came online during 2015.
But it warned that much more had to be done to avoid dangerous climate change.
The assessment, produced by the Frankfurt School-Unep Collaborating Centre for Climate and Sustainable Energy Finance and Bloomberg New Energy Finance, showed that the developing world committed a total of US$156bn (up 19% on 2014 levels) in renewables (excluding large hydro) while developed nations invested US$130bn (down 8% from 2014 levels).
"A large element in this turnaround was China, which lifted its investment by 17% to US$102.9bn, or 36% of the world total," the report observed.
However, other developing nations also contributed as six of the top 10 investors were developing nations.
In the foreword, UN secretary-general Ban Ki-moon said the report's findings increased confidence that a low-carbon world was obtainable.
He wrote: "We have entered a new era of clean energy growth that can fuel a future of opportunity and greater prosperity for every person on the planet."
However, he warned that in order to avoid dangerous climate change required an "immediate shift away from fossil fuels".

“Applying sound management reforms to global fisheries in our dataset could generate annual increases exceeding 16 million metric tons (MMT) in catch, $53 billion in profit, and 619 MMT in biomass relative to business as usual,” the authors explain in their study. “We also find that, with appropriate reforms, recovery can happen quickly, with the median fishery taking under 10 [years] to reach recovery targets. Our results show that commonsense reforms to fishery management would dramatically improve overall fish abundance while increasing food security and profits.”

“It’s pretty clear that some metropolitan areas are doing really well,” said Andrew McAfee, an economist at the Massachusetts Institute of Technology. “The ingredients to that formula seem to be some combination of great research universities and knowledge-intensive industries, whether it’s high tech on the West Coast, biotechnology here in the East or clusters of technology and robotics in places like Pittsburgh.”

Smog levels dropped significantly during Easter Week, when much of Mexico City empties out due to the holiday. But on Wednesday afternoon authorities were reporting a pollution index of 108 – officially “bad”, though about half the levels recorded at the peak of the Phase 1 alert.

The commission said that starting on 1 July, more modern technology will be put in place at smog-check centres. Vehicles are supposed to get checked every six months, though it’s common knowledge that for a bribe of $20 or so drivers can ensure a car comes out “clean”.

Is global warming causing marine diseases to spread?

Global climate change is altering the world’s oceans in many ways. Some impacts have received wide coverage, such as shrinking Arctic sea ice, rising sea levels and ocean warming. However, as the oceans warm, marine scientists are observing other forms of damage.
My research focuses on diseases in marine ecosystems. Humans, animals and plants are all susceptible to diseases caused by bacteria, viruses, parasites and fungi. Marine diseases, however, are an emerging field.
Infectious agents have the potential to alter ocean life in many ways. Some threaten our food security by attacking important commercial species, such as salmon. Others, such as bacteria in oysters, may directly harm human health. Still others damage valuable marine ecosystems – most notably coral reefs.
To anticipate these potential problems, we need a better understanding of marine diseases and how climate change affects their emergence and spread.
