Study tracks shift in nesting grounds as oceans warm
FRISCO — Scientist think climate change may be a key reason that thousands of seabirds are leaving their nesting grounds on an island in the Gulf of California and moving north.
In a new study, researchers from the University of California at Riverside looked at Isla Rasa, where more than 95 percent of the world’s population of elegant terns and Heerman’s gulls have traditionally nested.
In the past 20 years, the seabirds have abandoned the island and moved to other nesting grounds in Southern California including the San Diego Saltworks, Bolsa Chica Ecological Reserve, and Los Angeles Harbor. Continue reading

Mixing and matching corals from different latitudes may boost reef survival
FRISCO — If global warming can be capped at a reasonable level, some coral reefs may have a fighting chance to adapt to warmer ocean waters, according to new genetic research.
The new study suggests some coral species already have genetic variants necessary to tolerate warm ocean waters, and humans can help to spread these genes, said a team of scientists from The University of Texas at Austin, the Australian Institute of Marine Science and Oregon State University.

Global temperatures have reached record levels the past few months, with 2015 on track to be warmest year ever.
Heat waves, increased air pollution seen as key climate risks for Colorado
FRISCO — A new EPA report suggests that failing to curb greenhouse gas emissions could cause up to 57,000 additional deaths across the U.S. in coming decades due to poor air quality.
The study was released as part of the run-up to the finalization of the controversial Clean Power Plan, which aims to cut greenhouse gas emissions from power plants. The EPA is set to finalize the plan later this summer.
The report’s findings were part of the discussion at a Denver roundtable convened by Environment Colorado this week, as EPA experts joined with state leaders and health experts to bring the message home to Colorado.
“Climate change is already having an impact on human health and is challenging EPA’s ability to fulfill its mission,” said EPA regional climate change coordination Laura Ferris. “We know that taking action to reduce global greenhouse gas emissions will significantly benefit Americans by reducing health impacts, saving lives and avoiding more costly damages across the economy.” Continue reading

Oil and gas operations on public and tribal lands produce 21 percent of national emissions from gas production.
Study says easy fixes available to stop methane leaks
FRISCO — Methane emissions from oil and gas operations on federally managed public lands and tribal lands totaled more than 1 million tons in 2013, accounting for about 12 percent of total methane emissions across the U.S.
That methane was worth about $360 million at current gas prices, showing how oil and gas companies are squandering a valuable public resources and polluting the atmosphere, according to a new economic study released by the Environmental Defense Fund. Continue reading

Global warming is likely to cut native plant diversity in California, with cascading ecosystem effects, a new UC Davis study suggests. @bberwyn photo.
UC Davis study documents ‘direct loss’ of native wildflowers
FRISCO — California scientists say they’ve documented a loss in native wildflower diversity after with a string of dry winters, showing how climate change will affect the state’s grassland ecosystems.
The study is based on 15 years of monitoring on about 80 sampling plots at McLaughlin Reserve, part of the natural reserve system at the University of California at Davis. Continue reading

Pope Francis released his environmental encyclical just as climate scientists said that May was yet another record warm month for planet Earth, and that 2015 is likely to be the warmest year ever for the globe.
‘Those who profited least from the exploitation of fossil fuels and contributed least to greenhouse-gas emissions are hit hardest by global warming impacts’
FRISCO — It’s easiest to look at global warming through a purely scientific lens. Simple physics provide a completely logical explanation for the steady upward trend in global temperatures.
It’s much harder to to address the issue when you add politics and ethics to the equation, which is what Pope Francis sought to do with his recent “Laudato Si” encyclical on inequality and the environment.
Crafting the language may have been like walking on a tightrope above a political and religious minefield, but in the end, it will pay off by giving scientists more of a buffer for talking about climate and the environment in moral terms. Continue reading

Trucking industry cautiously supportive of new rules
There are a lot of trucks on the road these days, and they emit a lot of greenhouse gases. Proposed new federal rules could cut those emissions by 1 billion metric tons and amount to huge fuel savings for the trucking industry. @bberwyn photo.
FRISCO — The Obama administration says its proposed new fuel efficiency standards for trucks will cut CO2 emissions by 1 billion metric tons — about equal to the greenhouse gas emissions from all domestic energy use in the U.S.
The new rules would cut fuel costs by about $170 billion, and reduce oil consumption by up to 1.8 billion barrels, more than a year’s worth of imports from OPEC. Continue reading
