Record downpour paralyzes Washington, D.C. with flash flood – “This event goes off the scale”

By Jason Samenow, Ian Livingston, and Jeff Halverson 8 July 2019 (The Washington Post) – A month’s worth of rain deluged the immediate D.C. area early Monday, resulting in one of its most extreme flooding events in years. The record-setting cloudburst unleashed four inches of water in a single hour, way too much for a […]

From Libya to Texas, tragedies illustrate plight of migrants

By Lori Hinnant and Jamey Keaten 6 July 2019 GENEVA (AP) – They are trapped in squalid detention centers on Libya’s front lines. They wash up on the banks of the Rio Grande. They sink without a trace — in the Mediterranean, in the Pacific or in waterways they can’t even name. A handful fall […]

Anchorage, Alaska roasts in 90°F heat, smashing all-time record by 5°F

By Dr. Jeff Masters 5 July 2019 (Weather Underground) – The temperature in Alaska’s largest city of Anchorage soared to an astonishing 90°F on Thursday, July 4, smashing the city’s previous all-time heat record by a remarkable 5°F. Anchorage’s average high temperature for July 4 is 65°F; records for Anchorage date back to 1952. All-time […]

Glacier National Park’s name will outlive its glaciers – “It’s just kind of sad to see”

By Doug Struck 18 June 2019 GLACIER NATIONAL PARK, MONTANA (The Christian Science Monitor) – Maria Clemens took time off from her post-college summer job on a Montana ranch to hike into this national park to see a glacier. “I don’t like it,” she pronounced on the trail as she returned. “It’s just kind of […]

Warming Arctic permafrost releasing 12 times more nitrous oxide, a potent greenhouse gas, than previously thought – “This needs to be taken more seriously than it is right now”

By Caitlin McDermott-Murphy 6 June 2019 (The Harvard Gazette) – About a quarter of the Northern Hemisphere is covered in permafrost. Now, it turns out these permanently frozen beds of soil, rock, and sediment are actually not so permanent: They’re thawing at an increasing rate. Human-induced climate change is warming these lands, melting the ice […]

One-in-30-year heat-related mortality that is avoidable by stabilizing future warming at the 1.5° and 2°C Paris Agreement thresholds rather than 3°C. The point estimates show the mean 1-in-30-year mortality level across 101 plausible exposure-response relationships, whereas the error bars show the 95% eCI accounting for uncertainties from internal climate variability and the exposure-response relationship. All estimates assume constant population. Confidence intervals that do not include 0 (dotted line on each panel) indicate a statistically significant number of avoidable deaths. The size of each bubble on the central map is proportional to the square root of the city’s population in July 2016. The color of each bubble indicates the city’s projected population change between 2015 and 2040. Graphic: Lo, et al., 2019 / Science Advances

Adjusting carbon emissions to the Paris climate commitments would prevent thousands of heat-related deaths per city – “Compelling evidence for the heat-related health benefits of limiting global warming to 1.5°C”

5 June 2019 (University of Bristol) – Thousands of annual heat-related deaths could be potentially avoided in major US cities if global temperatures are limited to the Paris Climate Goals compared with current climate commitments, a new study led by the University of Bristol has found. The research, published today in the journal Science Advances, is […]

Arctic permafrost melting 70 years sooner than expected, study finds – “This change is unprecedented on this kind of time scale”

By Jan Wesner Childs 14 June 2019 (The Weather Channel) – Scientists studying climate change expected layers of permafrost in the Canadian Arctic to melt by the year 2090. Instead, it’s happening now. A new study published this week in the journal Geophysical Research Letters revealed that unusually warm summers in the Canadian High Arctic between 2003 […]

Video: New York is building a wall to hold back the ocean

10 June 2019 (Vox) – Climate change is leading to increasingly violent storms. Can seawalls hold back floods? Staten Island recently received funding for a nearly 5-mile-long seawall to protect its coast. But the plan raises a lot of questions. We’re living in a dangerously dynamic world: Hurricanes are getting worse, wildfires are rampant in […]

Hundreds of barges stalled as record floods hinder Midwest supplies – “Very long duration flooding on the Mississippi River can really start to wear on people”

By Brian K Sullivan , Shruti Singh, and Mario Parker 8 June 2019 (Bloomberg) – Hundreds of barges are stalled on the Mississippi River, clogging the main circulatory system for a farm-belt economy battered by a relentless, record-setting string of snow, rainstorms and flooding. Railways and highways have been closed as well, keeping needed supplies […]

Simultaneous heatwaves caused by anthropogenic climate change – “If in future more and more key agricultural regions and densely populated areas are affected by simultaneous heatwaves, this would have severe consequences”

By Peter Rüegg 9 April 2019 (ETH) – Without the climate change caused by human activity, simultaneous heatwaves would not have hit such a large area as they did last summer. This is the conclusion of researchers at ETH Zurich based on observational and model data. Many people will remember last summer – not only […]
