heatwave – Page 20 – Desdemona Despair

Heat dome strength of 4 sigma over the U.S. Pacific Northwest and Canadian West, 28 June 2021. The sigma is the standard deviation of a normal distribution of expected values. In this case the heat dome sigma max is 4.4, which mean that it's outside of 99.99 percent of expected values or a 1/10,000+ chance per year. Statistically speaking, there is a 1 in 10,000 chance of experiencing this value. So, if you could possibly live in that spot for 10,000 years, you'd likely only experience this kind of heat dome once, if ever. Graphic: By Jeff Berardelli / ECMWF

Pacific Northwest bakes under once-in-a-millennium heat dome – Heatwave has intensity never recorded by modern humans – “There is no analog in our past for what we are likely to see this week”

By Jeff Berardelli 28 June 2021 (CBS News) – The heatwave baking the U.S. Pacific Northwest and British Columbia, Canada, is of an intensity never recorded by modern humans. By one measure it is more rare than a once in a 1,000-year event — which means that if you could live in this particular spot […]

Potential heat stress risk in 2060-2099 due to combined climate and population projections. Periods of extremely high heat are projected to double across the lower 48 states by 2100 if the world continues to emit high levels of greenhouse gases. The heat stress will be felt most strongly in areas with growing populations. The Pacific Northwest, central California, and the Great Lakes region could experience as much as a threefold increase compared to the past 40 years.

Heat stress in U.S. may double by century’s end

7 June 2021 (NSF) – Periods of extremely high heat are projected to double across the lower 48 states by 2100 if the world continues to emit high levels of greenhouse gases, according to a new study in Earth’s Future, an American Geophysical Union journal. The heat stress will be felt most strongly in areas with growing populations. […]

Drought saps California reservoirs as hot, dry summer looms – “It makes me feel like our planet is literally drying up,”

By Adam Beam 17 June 2021 OROVILLE, Califorina (AP) – Each year Lake Oroville helps water a quarter of the nation’s crops, sustain endangered salmon beneath its massive earthen dam and anchor the tourism economy of a Northern California county that must rebuild seemingly every year after unrelenting wildfires. But the mighty lake — a […]

NOAA’s “new normal” climate report is anything but normal – “We’re really seeing the fingerprints of climate change in the new normals”

By Jeff Berardelli 8 May 2021 (CBS News) – Just a quick glance at the new U.S. Climate Normals maps published by the National Oceanic and Atmospheric Administration (NOAA) on Tuesday is enough for most climate scientists to say, “I told you so.” And it’s not just because the maps show a warmer and wetter […]

Map showing highest-impact disasters in 2020, during the Covid-19 pandemic (over 250,000 people affected). The map shows only a snapshot of disasters that took place from the beginning of the month when the epidemic was declared (March 2020) for a six-month period. More than 100 disasters occurred during this period and affected over 50 million people. There were also a number of ongoing crises, including measles in DRC and droughts in parts of east and southern Africa. Graphic: IFRC

Red Cross faced record number of climate-related disasters in 2020 – “This year has tested the resilience of tens of millions of people to breaking point”

KUALA LUMPUR, 16 December 2020 (IFRC) – In a record-breaking year, the International Federation of Red Cross and Red Crescent Societies (IFRC) has responded to more climate-related disasters across Asia Pacific than any other time this century so far. The IFRC has already responded to 25 climate-related disasters in the Asia Pacific, including floods, typhoons, […]

WMO: 2020 on track to be one of three warmest years on record – More than 80 percent of the global ocean experienced a marine heatwave in 2020

GENEVA, 2 December 2020 (WMO) – Climate change continued its relentless march in 2020, which is on track to be one of the three warmest years on record. 2011-2020 will be the warmest decade on record, with the warmest six years all being since 2015, according to the World Meteorological Organization. Ocean heat is at […]

August 2020 was the world’s second-warmest August on record – The year 2020 has more than a 99.9 percent chance to rank among the five warmest years on record

By Jeff Masters, Ph.D. 15 September 2020 (Yale Climate Connections) – August 2020 was the second-warmest August since global record keeping began in 1880, NOAA’s National Centers for Environmental Information, or NCEI, reported September 14. The month was just 0.04 degrees Celsius behind the record set in August 2016. NASA rated the month as the third-warmest August on […]

The Ozone Mapping and Profiler Suite (OMPS) and the Visible Infrared Imaging Radiometer Suite (VIIRS) on the NOAA-NASA Suomi NPP satellite captured this extremely think blanket of smoke along the West Coast on 9 September 2020. OMPS measured smoke clouds over the western U.S. with higher aerosol index values than anything Colin Seftor, an atmospheric scientist at NASA’s Goddard Space Flight Center, says he has ever seen with the instrument.

California’s wildfire smoke plumes are unlike anything previously seen – California fire carbon emissions in 2020 exceed previous record by nearly 2 times

By Matthew Cappucci 12 September 2020 (The Washington Post) – More than 3.1 million acres have burned in California this year, part of a record fire season that still has four months to go. A suffocating cloud of smoke has veiled the West Coast for days, extending more than a thousand miles above the Pacific. And the […]

Satellite images show Phoenix and Talent, Oregon, have been “substantially destroyed” by wildfire – “This could be the greatest loss of human lives and property due to wildfire in our state’s history”

By Paul P. Murphy 10 September 2020 (CNN) – Swaths of the small southern Oregon cities of Phoenix and Talent now lie in ash, satellite images show, as wildfires wage unprecedented destruction across the US West. A massive burn scar cuts through parts of Talent and Phoenix, home to about 11,000 people combined. The wounded terrain, seen […]

California heatwaves are becoming more frequent and lasting longer – “This has serious consequences for the fire season in Southern California”

By Kasha Patel 11 September 2020 (NASA) – In early September 2020, an intense heatwave broke temperature records in several locations in Southern California. The dry, hot conditions helped fuel new and existing fires, which have consumed tens of thousands of acres of land. According to recently published research, these extremes fit a long-term trend toward longer and more […]
