These are the biggest risks facing our world in 2019 – “Of all risks, it is in relation to the environment that the world is most clearly sleepwalking into catastrophe”

By Joe Myers and Kate Whiting 16 January 2019 (WEF) – What keeps you up at night? For leaders surveyed for the latest edition of the World Economic Forum’s Global Risks Report, environmental threats dominate the list for the third year in row – both in terms of impact and likelihood. “Of all risks, it is […]

Australia fire smoke will complete a full circuit of Earth, NASA says

14 January 2020 (BBC News) – Smoke from the massive bushfires in Australia will soon circle the Earth back to the nation, says NASA. Massive infernos have raged along the nation’s east coast for months, pushing smoke across the Pacific. NASA said plumes from blazes around New Year’s Day had crossed South America, turning skies […]

On 1 January 2016 and 2 January 2016, 6,540 common murre carcasses were found washed ashore near Whitter, Alaska, translating into about 8,000 bodies per mile of shoreline — one of the highest beaching rates recorded during the mass mortality event. Photo: David B. Irons

Huge “hot blob” in Pacific Ocean caused mass starvation in largest seabird die-off – “The magnitude and scale of this failure has no precedent”

By Michelle Ma 15 January 2020 (UW News) – The common murre is a self-sufficient, resilient bird. Though the seabird must eat about half of its body weight in prey each day, common murres are experts at catching the small “forage fish” they need to survive. Herring, sardines, anchovies and even juvenile salmon are no […]

Europe’s demographic time-bomb – While global population is ageing, continent presents extreme example of this trend

By Valentina Romei 13 January 2020 LONDON (Financial Times) – With its low birth rate and fast-ageing population, Europe is facing a demographic crisis, one that economists fear could hit growth and public finances.  While the global population overall is getting older, Europe is an extreme example of this trend, particularly in the continent’s south and […]

Precipitation averages in the contiguous U.S. for overlapping two-year calendar periods, 1895-2019. The period 2018-19 was the wettest of these, with 69.43” coming in well above the previous record of 68.62” from 1982-83. Graphic: NOAA / NCEI

Second wettest year in U.S. history – Warmest year on record in Alaska

By Bob Henson 8 January 2020 (Weather Underground) – Capping a spectacularly soggy period that spanned parts of two calendar years, the contiguous United States saw its second wettest year on record in 2019, according to NOAA’s annual summary issued on Wednesday. The national average temperature wasn’t especially hot by recent standards, but there were […]

Preliminary U.S. carbon emissions estimates for 2019 – Coming up short on climate targets

By Trevor Houser and Hannah Pitt 7 January 2020 (Rhodium Group) – After a sharp uptick in 2018, we estimate that US greenhouse gas (GHG) emissions fell by 2.1% last year based on preliminary energy and economic data. This decline was due almost entirely to a drop in coal consumption. Coal-fired power generation fell by […]

Worldwide natural catastrophe loss events in 2019. Tropical cyclones, extreme storms, and floods caused overall losses of $150 billion. Video: Munich RE

Tropical cyclones causing billions in losses dominated the natural catastrophe picture of 2019 – “Cyclones are becoming more frequently associated with extreme precipitation”

8 January 2020 (Munich RE) – 820 natural catastrophes caused overall losses of US$ 150bn, which is broadly in line with the inflation-adjusted average of the past 30 years. A smaller portion of losses was insured compared with 2018: about US$ 52bn. This was due, among other things, to the high share of flood losses, which are […]

The sad truth about our boldest climate target – Limiting global warming to 1.5˚C is almost certainly not going to happen. Admitting this need not end hope.

By David Roberts 3 January 2020 (Vox) – In the 2015 Paris climate agreement, the countries participating in the United Nations Framework Convention on Climate Change (UNFCCC) agreed to a common target: to hold the rise in global average temperature “well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even […]

2010-2019: Earth’s hottest decade on record marked by extreme storms, deadly wildfires – “The climate of the 20th Century is gone. We’re in a new neighborhood.”

By Bob Berwyn 19 December 2019 (InsideClimate News) – Deadly heat waves, wildfires and widespread flooding punctuated a decade of climate extremes that, by many scientific accounts, show global warming kicking into overdrive. As the year drew to a close, scientists were confidently saying 2019 was Earth’s second-warmest recorded year on record, capping the warmest […]

The signal of human-caused climate change has emerged in everyday weather, study finds – “Weather is climate change if you look over the whole globe”

By Andrew Freedman 2 January 2020 (The Washington Post) – For the first time, scientists have detected the “fingerprint” of human-induced climate change on daily weather patterns at the global scale. If verified by subsequent work, the findings, published Thursday in Nature Climate Change, would upend the long-established narrative that daily weather is distinct from long-term […]
