Data gathered by citizen scientists suggests that bluebells and some other spring wildflowers are slipping out of synch with seasonal temperature cycles. A study published this week in Global Change Biology looked at 22 species of plants; all of them were found to be responding to warming temperatures in spring, by changing when their leaves or flowers emerged.
European Climate Change Service report highlights unusually warm Arctic
Warmer than average temperatures prevailed around the globe in January 2017.
January 2017 will go down in the books as Earth’s second-warmest January on record, just 0.17 degrees cooler than last year, according to the monthly update from the European Climate Change Service. According to the bulletin, January was 0.55 degrees warmer than the 1981-2010 average, with hotspots especially across Southern Hemisphere continents, as well as the southeastern U.S.
In the Northern Hemisphere, Europe was about 1 degree Celsius cooler the 1981-2010 January average, similar to 2016. Other cooler-than-average areas included parts of the western USA and Canada, northern Greenland, North Africa, parts of Siberia, southern Africa, north-western Australia and much of the Antarctic plateau.

Long-term carbon storage in soil crucial to climate mitigation
Coastal wetlands like mangrove forests, seagrass meadows and tidal marshes play a key role in the global carbon cycle, serving as effective long-term reservoirs for so-called blue carbon. Their role is so important they should be considered in global climate change mitigation strategies, according to a new study published last week n the journal Frontiers in Ecology and the Environment.
Spruce beetles continued to expand in Colorado in 2016, at least in part due to global warming and drought, as well as the density of old-growth spruce forests.
In all, spruce beetles were active across 350,000 acres of higher-elevation stands of Engelmann spruce statewide, including about 136,000 acres of new activity, causing widespread tree mortality, according to the results of the latest aerial surveys conducted by the U.S. Forest Service and the Colorado State Forest Service. Since 1996, spruce beetle outbreaks have caused tree mortality on more than 1.7 million acres in Colorado. Continue reading “Spruce beetles still on the march in Colorado”→
New CSU study eyes regional climate cycle as one factor
This year’s rapid loss of sea ice around Antarctica may make the floating ice shelves along the coast of the continent even more vulnerable to collapse, and a Hemisphere climate cycle known as the Southern Annular Mode is probably a factor in the equation.
Planned test site in Oregon could help answer the question, but will it survive Trump?
All eyes are on wind and solar these days, and rightly so, but ocean waves may play an even bigger role in humanity’s efforts to decarbonize energy production. Scientists and engineers in the Pacific Northwest may get a chance to show how that can happen with a new wave energy test facility in Newport, Oregon.
Last month, Oregon State University’s Northwest National Marine Renewable Energy Center today was awarded up to $40 million from the U.S. Department of Energy for the Pacific Marine Energy Center South Energy Test Site, which should be operational by 2020. It will be able to test wave energy “converters” that harness the energy of ocean waves and turn it into electricity. Companies around the world are already anticipating construction of the new facility to test and perfect their technologies, OSU officials say.
