Yellow Fever Mosquito gets a full meal — James Gathany/CDC
❝ Rising global temperatures could put half a billion more people at risk for tropical mosquito-borne diseases like chikungunya, dengue, yellow fever, and Zika by 2050, according to a new study.
❝ While a growing body of recent research warns the human-caused climate crisis will cause general worldwide “environmental breakdown,” a study published…in the journal PLOS Neglected Tropical Diseases focuses specifically on a related public health threat: how a hotter world will enable disease-carrying mosquitoes to reach more people…
❝ “Plain and simple, climate change is going to kill a lot of people,” coauthor Colin Carlson of Georgetown told Nexus Media News. “Mosquito-borne diseases are going to be a big way that happens, especially as they spread from the tropics to temperate countries.”
Lead author Ryan emphasized that public health experts should be preparing now for the outbreaks predicted to occur in new places over the next few decades.
Or we could leave responsibility in the hands of Trump-chumps, anti-vaxxers and the Republican Party. They’ll blame it all on weak walls, furriners and G_D’s WILL.
❝ By the 2080s, the climate of North American urban areas will feel substantially different, and, in many cases, completely unlike contemporary climates found anywhere in the western hemisphere north of the equator. If emissions continue unabated throughout the 21st century,the climate of North American urban areas will become, on average, most like the contemporary climate of locations about 500 miles away and mainly to the south…
❝ Scientists analyzed 540 urban areas that encompassed approximately 250 million inhabitants in the United States and Canada. For each urban area, they mapped the similarity between that city’s future climate expected by the 2080s and contemporary climate in the western hemisphere north of the equator using 12 measures of climate, including minimum and maximum temperature and precipitation during the four seasons.

❝ A gigantic cavity – two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall – growing at the bottom of Thwaites Glacier in West Antarctica is one of several disturbing discoveries reported in a new NASA-led study of the disintegrating glacier. The findings highlight the need for detailed observations of Antarctic glaciers’ undersides in calculating how fast global sea levels will rise in response to climate change.
❝ Researchers expected to find some gaps between ice and bedrock at Thwaites’ bottom where ocean water could flow in and melt the glacier from below. The size and explosive growth rate of the newfound hole, however, surprised them. It’s big enough to have contained 14 billion tons of ice, and most of that ice melted over the last three years…
❝ About the size of Florida, Thwaites Glacier is currently responsible for approximately 4 percent of global sea level rise. It holds enough ice to raise the world ocean a little over 2 feet (65 centimeters) and backstops neighboring glaciers that would raise sea levels an additional 8 feet (2.4 meters) if all the ice were lost.
RTFA. Nice of the French and Germans to help us out with this research. Our government thinks we need more aircraft carriers and the beginnings of a whole new project to redesign rifles for the whole US Army.

❝ Melting ice is exposing hidden landscapes in the Canadian Arctic that haven’t been seen in more than 40,000 years, new research published in Nature Communications reveals.
Unsurprisingly, the study suggests climate change is the driving force behind this record-breaking glacial retreat and with Arctic temps rising at increasing speed thanks to strong positive feedback loops in the polar regions, we can expect things to heat up even quicker in the near future. According to researchers at the University of Colorado at Boulder, the Canadian Arctic may be seeing its warmest century in as many as 115,000 years…
❝ Simon Pendleton and colleagues’ research is based on plants collected at the edge of ice caps on Baffin Island, the fifth-largest island in the world. The landscape is dominated by deeply incised fjords and high-elevation, low-relief plateaus. The latter conserves lichens and moss in their original position in the ice for periods of time lasting thousands of years — a little like a cryogenic chamber.
RTFA to learn why scientists like Pendleton have to be hot on the spot to gather samples of vegetation as it becomes exposed.
❝ …The world’s largest wind-power producer, Iberdrola SA, has brushed off Big Oil’s embrace of renewable energy as “more noise” than action.
Major oil and gas firms have been venturing into renewable power under pressure from climate-change policy, collectively spending around 1 percent of their 2018 budgets on clean energy…
❝ However, Iberdrola Chief Executive Ignacio Galan, who has led the Spanish utility for 17 years, shrugged when asked in a Reuters interview if Big Oil represented a competitive threat.
“It’s good that they have moved in this direction but they make more noise than the reality,” he said on Thursday on the sidelines of the World Economic Forum in Davos, Switzerland…
❝ He said U.S. states were more influential than Washington in terms of energy investment, and that several were looking to develop America’s first offshore wind farms, from Massachusetts down to North Carolina and New York across to California.
“The states are more and more committed to moving to renewables and the same is true of the cities and towns,” he said, adding that falling generation costs of renewable energy was a big driver of the U.S. adoption of wind and solar power.
Woo-hoo. I knew they were taking on the first big US wind-power project off Martha’s Vineyard. Hadn’t realized the size of their immediate follow-on commitment. [Davos has been really interesting this year and the coverage from Bloomberg TV has been stellar.]
❝ Climate change works in mysterious ways; it isn’t limited to wildfires and melting ice. Today’s climate exhibit: The 100th Meridian — the famous dividing line that separates America’s wet East from the dry West — has migrated 140 miles east since 1980…
❝ The shift is the result of rising temperatures drying out parts of the northern plains and less rain falling further south, YaleEnvironment360 reports. This could be due to natural variability — changes caused by nonhuman forces — but the migration aligns with what researchers tell us to expect from global warming.

The scariest entity to emerge from the melt so far is methane, a greenhouse gas 30 times more potent than CO2. Released when formerly frozen matter decomposes in thawed tundra, the gas boosts atmospheric temperatures, defrosting more acreage—a spine-chilling feedback loop.
