More than 100 Arctic wildfires burn in worst-ever fire season – Smoke plumes from huge blazes in Greenland, Siberia, and Alaska visible from space – “These are some of the biggest fires on the planet, with a few appearing to be larger than 100,000 hectares”

By Edward Helmore 26 July 2019 (The Guardian) – The Arctic is suffering its worst wildfire season on record, with huge blazes in Greenland, Siberia, and Alaska producing plumes of smoke that can be seen from space. The Arctic region has recorded its hottest June ever. Since the start of that month, more than 100 wildfires have […]

Remote sensing imagery of discolored water and algal blooms in the Florida Bay and the Florida Keys region between 1992 and 2013 showing connectivity of the mainland and the lower Florida Keys, all outlined in red. (a) Landsat true color image on 29 May 1992 shows turbid water in western Florida Bay and discolored, black water in central Florida Bay that extends southward to the lower Florida Keys; (b) AVHRR reflectance image on 12 March 1996 shows high turbidity from the Shark River Slough plume extending beyond the lower Florida Keys towards Dry Tortugas; (c, d) VIIRS chlorophyll a anomaly images show phytoplankton blooms off Shark River Slough reaching the lower Florida Keys that were partially composed of the cyanobacterium, Synechococcus, on (c) 24 November 2013 and (d) 27 January 2014.

Nutrient loading lowers resistance to thermal stress in Florida Keys corals – “These data make clear that this is not an ‘either temperature or nutrients’ situation, but rather a ‘both/and’ combination of multiple stressors”

By Gisele Galoustian 15 July 2019 (FAU) – Coral reefs are considered one of the most threatened ecosystems on the planet and are dying at alarming rates around the world. Scientists attribute coral bleaching and ultimately massive coral death to a number of environmental stressors, in particular, warming water temperatures due to climate change. A […]

U.S. farmers now face extreme heat wave after floods and trade war – “We’ve never seen a year like this”

By Emma Newburger 20 July 2019 (CNBC) – In the past year, torrential rains have dumped water on U.S. farmlands, destroying acreage and delaying crops from getting planted on time. Now, farmers face another hurdle: a stifling heat wave that’s spreading across the United States and is expected to be the worst in the farm […]

By Brian Kahn 18 July 2019 (Gizmodo) – Vast stretches of Earth’s northern latitudes are on fire right now. Hot weather has engulfed a huge portion of the Arctic, from Alaska to Greenland to Siberia. That’s helped create conditions ripe for wildfires, including some truly massive ones burning in remote parts of the region that […]

Nunavut is warmer than Victoria in long, hot summer across the Arctic – “It’s really quite spectacular. This is unprecedented.”

By Bob Weber 15 July 2019 (The Canadian Press) – Weather watchers are focused on the world’s most northerly community, which is in the middle of a record-breaking heat wave. “It’s really quite spectacular,” said David Phillips, Environment Canada’s chief climatologist. “This is unprecedented.” The weather agency confirmed that Canadian Forces Station Alert hit a record […]

Global warming drives 8X increase in California summer wildfires and 5X increase in area burned – “The ability of dry fuels to promote large fires is nonlinear”

By Kevin Krajick 15 July 2019 (Columbia University) – Against a backdrop of long-term rises in temperature in recent decades, California has seen ever higher spikes in seasonal wildfires, and, in the last two years, a string of disastrous, record-setting blazes. This has led scientists, politicians and media to ponder: what role might warming climate be […]

Ohio statewide butterfly population trends of nine resident species with annual variation. Plotted are model predictions for each year based on the fixed effects of year (solid line) and annual random effects (dots) to show annual variation about the trend line. Shading shows 95 percent confidence intervals based on bootstrapped model fits in the poptrend package for the temporal trend and for the annual random effects. The first year’s estimate is set to a value of 1 as a baseline for relative population changes. Graphic: Wepprich, et al., 2019 / PLOS ONE

Decades-long butterfly study shows 33 percent population loss – “These declines in abundance are happening in common species”

By Steve Lundeberg 2 July 2019 CORVALLIS, Oregon (Oregon State University) – The most extensive and systematic insect monitoring program ever undertaken in North America shows that butterfly abundance in Ohio declined yearly by 2%, resulting in an overall 33% drop for the 21 years of the program. Though the study was limited to one […]

Devastating floods possible as Tropical Storm Barry sloshes into Louisiana – “It doesn’t matter what the storm is called. We are still expecting a major rainfall flood event.”

By Bob Henson 12 July 2019 (Weather Underground) – Residents of southeast Louisiana need to finalize preparations for widespread and severe flooding this weekend with the approach of Tropical Storm Barry. Packing top sustained winds of 65 mph, slow-moving Barry will push its way onshore Saturday, possibly as a Category 1 hurricane. What matters most […]

Wettest 12 months in U.S. history, yet again

By Bob Henson 9 July 2019 (Weather Underground) – Topping a remarkable record that was set just a month earlier, the year-long period ending in June was the wettest 12-month span in U.S. records that go back to 1895. For the 48 contiguous U.S. states, precipitation averaged 37.86” over the period from July 2018 to […]

Total U.S. managed honey bee colonies loss estimates 2006-2019. For the entire survey period (1 April 2018 – 1 April 2019), beekeepers in the U.S. lost an estimated 40.7 percent of their managed honey bee colonies. This is similar to last year’s annual loss estimate of 40.1 percent, but slightly higher (2.9 percentage points) than the average annual rate of loss reported by beekeepers since 2010-11 (37.8 percent).

Nearly 40 percent decline in honey bee population last winter “unsustainable” – Trump administration cuts funding for bee research

By Julia Jacobo 9 July 2019 (ABC News) – Scientists are researching the potential consequences of the rapid decline of the honey bee population in the U.S. and how to mitigate its effects before it causes dire problems for crop management and production. Honey bees are essential for the pollination of flowers, fruits and vegetables, and support about $20 […]
