World’s rivers awash with dangerous levels of antibiotics – “It’s quite scary and depressing”

By Natasha Gilbert 26 May 2019 (The Guardian) — Hundreds of rivers around the world from the Thames to the Tigris are awash with dangerously high levels of antibiotics, the largest global study on the subject has found. Antibiotic pollution is one of the key routes by which bacteria are able develop resistance to the […]

Sea level rise could displace millions of people within two generations

By Jonathan Bamber and Michael Oppenheimer 20 May 2019 (The Conversation) – Antarctica is further from civilisation than any other place on Earth. The Greenland ice sheet is closer to home but around one tenth the size of its southern sibling. Together, these two ice masses hold enough frozen water to raise global mean sea […]

A quarter of West Antarctic ice is now unstable – “A wave of thinning has spread rapidly across some of Antarctica’s most vulnerable glaciers, and their losses are driving up sea levels around the planet”

A quarter of West Antarctic ice is now unstable – “A wave of thinning has spread rapidly across some of Antarctica’s most vulnerable glaciers, and their losses are driving up sea levels around the planet”

16 May 2019 (University of Leeds) – In only 25 years, ocean melting has caused ice thinning to spread across West Antarctica so rapidly that 24 percent of its glacier ice is now affected, according to a new study. By combining 25 years of European Space Agency satellite altimeter measurements and a model of the […]

In 1982, Exxon predicted 2019’s ominous carbon dioxide milestone

By Brian Kahn 14 May 2019 (Gizmodo) – Atmospheric carbon dioxide sets a new record every year. This year’s cracked the ominous milestone of 415 parts per million (ppm) thanks to ever rising emissions from human activities. The sharp rise might seem like something nobody could’ve predicted but there’s at least one group of scientists that were […]

Occurrence of back-to-back heat waves likely to accelerate with global warming – “Compound heat waves are projected to grow more rapidly than simple heat waves”

Occurrence of back-to-back heat waves likely to accelerate with global warming – “Compound heat waves are projected to grow more rapidly than simple heat waves”

By Joseph Albanese 8 May 2019 (Princeton Environmental Institute) – As the planet continues to warm, multi-day heat waves are projected to increase in frequency, length and intensity. The additive effects of these extreme heat events overwhelm emergency service providers and hospital staff with heat-related maladies, disrupt the electrical grid and can even cause delays […]

Atmospheric carbon dioxide exceeds 415 ppm for the first time in human history – “We don’t know a planet like this”

By Peter Dickrill 13 May 2019 (Science Alert) – Yet another alarming milestone of humanity’s damaging effect on the environment has now officially been reached – crossing a barrier into a hot, polluted future like the planet hasn’t witnessed in millions of years. This weekend, sensors in Hawaii recorded Earth’s atmospheric concentration of carbon dioxide […]

Global fossil fuel subsidies hit record $5.2 trillion – Efficient pricing would lower global carbon emissions by 28 percent and fossil fuel air pollution deaths by 46 percent

By Nick Cunningham 12 May 2019 (OilPrice.com) – The world spent a staggering $4.7 trillion and $5.2 trillion on fossil fuel subsidies in 2015 and 2017, respectively, according to a new report [pdf] from the International Monetary Fund. That means that in 2017 the world spent a whopping 6.5 percent of global GDP just to subsidize the […]

Climate change has worsened global economic inequality – “Most of the poorest countries on Earth are considerably poorer than they would have been without global warming,”

By Josie Garthwaite 22 April 2019 (Stanford University) – A new Stanford University study shows global warming has increased economic inequality since the 1960s. Temperature changes caused by growing concentrations of greenhouse gases in Earth’s atmosphere have enriched cool countries like Norway and Sweden, while dragging down economic growth in warm countries such as India and Nigeria. […]

Loss of marine stratocumulus clouds could trigger a mega-hothouse climate – “Transitions to a much warmer climate may occur in the future if CO2 levels continue to rise”

Loss of marine stratocumulus clouds could trigger a mega-hothouse climate – “Transitions to a much warmer climate may occur in the future if CO2 levels continue to rise”

By Dr. Jeff Masters 6 May 2019 (Weather Underground) – If humanity maintains its current business-as-usual emissions path for the next 100 years, the resulting 4°C (7°F) of warming may be enough to cause highly reflective stratocumulus clouds over the subtropical and tropical oceans to disintegrate, resulting in an additional 8°C (14°F) of warming, according […]

North Atlantic Ocean phytoplankton decline coincides with warming temperatures over the last 150 years – “10 percent of the marine food base in this region has been lost over the industrial era”

North Atlantic Ocean phytoplankton decline coincides with warming temperatures over the last 150 years – “10 percent of the marine food base in this region has been lost over the industrial era”

By Jennifer Chu 6 May 2019 (MIT News) – Virtually all marine life depends on the productivity of phytoplankton — microscopic organisms that work tirelessly at the ocean’s surface to absorb the carbon dioxide that gets dissolved into the upper ocean from the atmosphere. Through photosynthesis, these microbes break down carbon dioxide into oxygen, some […]
