Summer swelter trend: U.S. West gets hotter days, East hot nights – “Hotter summers for the broader region are here to stay”

By Seth Borenstein 4 July 2021 (AP) – As outlandish as the killer heatwave that struck the Pacific Northwest was, it fits into a decades-long pattern of uneven summer warming across the United States. The West is getting roasted by hotter summer days while the East Coast is getting swamped by hotter and stickier summer […]

Wildfire forces evacuation for British Columbia town that hit a record 121 degrees – “The whole town is on fire”

LYTTON, British Columbia, 1 July 2021 (AP) – A wildfire amid a record heatwave in western Canada has forced authorities to order residents to evacuate a village in British Columbia that smashed the country’s record for hottest temperature three days in a row this week. Mayor Jan Polderman of Lytton issued the evacuation order Wednesday, […]

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 […]

Global quantities of cocaine seized, by region, 1998–2019. Quantities of cocaine seized reached record levels in 2019. In 2019, the global quantity of cocaine seized increased by 9.6 percent compared with the preceding year to reach 1,436 tons (of varying purities), a record high. The 90 percent increase in the quantities of cocaine seized between 2009 and 2019 is likely a reflection of a combination of factors, including an increase in cocaine manufacture (50 per cent between 2009 and 2019) and a subsequent increase in cocaine trafficking, as well as an increase in the efficiency of law enforcement, which may have contributed to an increase in the overall interception rate.

Illegal drug trade back to business as usual in 2020 and 2021 – Cocaine production hits record high – Number of people using illegal drugs increased by 22 percent in 2010-2019 decade

By Pia Lee-Brago 28 June 2021 (The Philippine Star) – Around 275 million people used illegal drugs worldwide in the last year of unprecedented upheaval caused by the COVID-19 pandemic, up by 22 percent from 2010, and it is “business as usual” again for drug traffickers, according to the latest annual world drug report by […]

Seasonal honey bee colony loss rates in the United States, 2008-2021. Annual loss estimates (from one 1 April to the next 1 April) combine winter (1 October – 1 April) and summer (1 April – 1 October) losses. The loss rate was calculated as the total number of colonies lost divided by the number of colonies “at risk” during the season. Colonies at risk were composed of viable colonies and new colonies made or acquired, while excluding colonies sold or parted with. Graphic: Bee Informed Partnership

U.S. honey bee colonies hit by second-highest annual loss on record in 2021

By Nathalie Steinhauer, Dan Aurell, Selina Bruckner, Mikayla Wilson, Karen Rennich, Dennis vanEngelsdorp, and Geoffrey Williams 23 June 2021 (Bee Informed Partnership) – The Bee Informed Partnership (http://beeinformed.org) is a non-profit organization that works alongside beekeepers to improve honey bee colony health and survivorship across the United States. One of the organization’s longest running programs, […]

Hunger, drought, disease: UN climate report reveals dire health threats – “The basis for our health is sustained by three pillars: the food we eat, access to water, and shelter. These pillars are totally vulnerable and about to collapse.”

By Patrick Galey 23 June 2021 (AFP) – Hunger, drought and disease will afflict tens of millions more people within decades, according to a draft UN assessment that lays bare the dire human health consequences of a warming planet. After a pandemic year that saw the world turned on its head, a forthcoming report by […]

The American West is drying out – Lake Mead, largest reservoir in U.S., drops to lowest level on record since it was filled in the 1930s

By Zachary B. Wolf 20 June 2021 (CNN) – The incredible pictures of a depleted Lake Mead, on the Nevada-Arizona border, illustrate the effects of drought brought on by climate change. Later this year, the US government will almost certainly declare the first-ever water shortage along the Colorado River. Maps show more than a quarter of the US […]

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. […]

Covid data from U.S. states plotted from 8 regions, as defined by the US Bureau of Economic Analysis. Surge patterns were independently examined for each of the 8 regions; epidemic patterns were similar and could be merged as shown, except a bimodal pattern in the Great Lakes region was distinctive and plotted separately. Negative excess deaths were plotted as zero. Between 1 March 2020, and 2 January 2021, the US experienced 2,801,439 deaths, 22.9% more than expected, representing 522,368 excess deaths. The excess death rate was higher among non-Hispanic Black (208.4 deaths per 100 000) than non-Hispanic White or Hispanic populations (157.0 and 139.8 deaths per 100 000, respectively); these groups accounted for 16.9%, 61.1%, and 16.7% of excess deaths, respectively. The US experienced 4 surge patterns: in New England and the Northeast, excess deaths surged in the spring; in the Southeast and Southwest, in the summer and early winter; in the Plains, Rocky Mountains, and far West, primarily in early winter; and in the Great Lakes, bimodally, in the spring and early winter.

U.S. excess deaths rose a staggering 23 percent in 2020 – “They said they were opening early to rescue the economy. The tragedy is that not only cost more lives but actually hurt their economy by extending the length of the pandemic.”

By Mary Kate Brogan 2 April 2021 (VCU News) – Extended surges in the South and West in the summer and early winter of 2020 resulted in regional increases in excess death rates, both from COVID-19 and from other causes, a 50-state analysis of excess death trends has found. Virginia Commonwealth University researchers’ latest study […]

Graph showing Earth Overshoot Day, 1970-2021. Each year, Earth Overshoot Day marks the date when humanity has used all the biological resources that Earth regenerates during the entire year. Humanity currently uses 74% more than what the planet’s ecosystems can regenerate—or “1.7 Earths.” From Earth Overshoot Day until the end of the year, humanity operates on ecological deficit spending. This spending is currently some of the largest since the world entered into ecological overshoot in the early 1970s, according to the National Footprint & Biocapacity Accounts (NFA) based on UN datasets.
