As climate warms, plants will absorb less carbon dioxide

As climate warms, plants will absorb less carbon dioxide

Comments 0 Comment

The New York Times reports: The last time the atmosphere contained as much carbon dioxide as it does now, dinosaurs roamed what was then a verdant landscape. The earth’s lushness was at least partly caused by the abundance of CO₂, which plants use for photosynthesis. That has led to the idea that more CO₂ in the atmosphere could create a literally greener planet. Today, plants and soil around the world absorb roughly a quarter of the greenhouse gases that humans…

Insect collapse: ‘We are destroying our life support systems’

Insect collapse: ‘We are destroying our life support systems’

Comments 0 Comment

The Guardian reports: “We knew that something was amiss in the first couple days,” said Brad Lister. “We were driving into the forest and at the same time both Andres and I said: ‘Where are all the birds?’ There was nothing.” His return to the Luquillo rainforest in Puerto Rico after 35 years was to reveal an appalling discovery. The insect population that once provided plentiful food for birds throughout the mountainous national park had collapsed. On the ground, 98%…

Hotter oceans mean we are in the emergency phase of climate change

Hotter oceans mean we are in the emergency phase of climate change

Eric Holthaus writes: The Earth’s surface is 70 percent water, but even that underestimates how vital ocean health is to our planet’s ability to maintain life. Recent results from scientists around the world only further confirm that our waterworld is in serious danger. Last week, a bombshell study confirmed that the oceans are warming 40 percent faster than many scientists had previously estimated. The finding partially resolved a long-running debate between climate modelers and oceanographers. By measuring the oceans more…

Luxembourg makes all public transport free

Luxembourg makes all public transport free

CNN reports: With a population of 602,000, Luxembourg is one of Europe’s smallest countries — yet it suffers from major traffic jams. But that could be about to change. Last month, it announced plans to make all public transport — trains, trams and buses — free from March 2020. The government hopes the move will alleviate heavy congestion and bring environmental benefits, according to Dany Frank, a spokesperson for the Ministry of Mobility and Public Works. Landlocked Luxembourg is one…

How Trump is poisoning America

How Trump is poisoning America

Comments 0 Comment

The New York Times reports: Had Donald J. Trump not won the presidency in 2016, millions of pounds of chlorpyrifos most likely would not have been applied to American crops over the past 21 months. It would not have sickened substantial numbers of farm workers, or risked what the Environmental Protection Agency’s own studies suggest could be continued long-term health problems for others exposed to the chemical at low levels. Widespread concerns about chlorpyrifos led to its removal for nearly…

Japan to resume commercial whaling, defying international ban

Japan to resume commercial whaling, defying international ban

Comments 0 Comment

The New York Times reports: Japan said on Wednesday that it would withdraw from an international agreement and resume commercial whaling, a defiant move to prop up an industry that still has cultural significance there, despite plummeting demand for whale meat. Yoshihide Suga, Japan’s chief cabinet secretary, said the country would leave the International Whaling Commission, which established a moratorium on hunting whales that took effect in 1986. The international agreement never stopped Japanese whaling, because it allowed the country…

Brazil’s Amazon rain forest is in the crosshairs, as defenders step up

Comments 0 Comment

Andrew Revkin writes: By now, anyone worried about the fate of the Amazon rain forest or the indigenous and traditional communities depending on this vast, rich ecosystem knows the litany of potentially devastating steps [Brazil’s newly elected far-right president, Jair] Bolsonaro has threatened to take. He won on a platform mainly built around change and order after the worst string of corruption scandals and economic troubles in Brazil’s modern history. But he also wooed rural landowners and businessmen, appealing to…

Risks of ‘domino effect’ of ecological tipping points greater than thought, study says

Risks of ‘domino effect’ of ecological tipping points greater than thought, study says

Comments 0 Comment

The Guardian reports: Policymakers have severely underestimated the risks of ecological tipping points, according to a study that shows 45% of all potential environmental collapses are interrelated and could amplify one another. The authors said their paper, published in the journal Science, highlights how overstressed and overlapping natural systems are combining to throw up a growing number of unwelcome surprises. “The risks are greater than assumed because the interactions are more dynamic,” said Juan Rocha of the Stockholm Resilience Centre….

The race to understand Antarctica’s most terrifying glacier

The race to understand Antarctica’s most terrifying glacier

Comments 0 Comment

Jon Gertner writes: Few places in Antarctica are more difficult to reach than Thwaites Glacier, a Florida-sized hunk of frozen water that meets the Amundsen Sea about 800 miles west of McMurdo. Until a decade ago, barely any scientists had ever set foot there, and the glacier’s remoteness, along with its reputation for bad weather, ensured that it remained poorly understood. Yet within the small community of people who study ice for a living, Thwaites has long been the subject…

Rapid warming caused largest extinction event ever on Earth, report says

Rapid warming caused largest extinction event ever on Earth, report says

Comments 0 Comment

The Guardian reports: Rapid global warming caused the largest extinction event in the Earth’s history, which wiped out the vast majority of marine and terrestrial animals on the planet, scientists have found. The mass extinction, known as the “great dying”, occurred around 252m years ago and marked the end of the Permian geologic period. The study of sediments and fossilized creatures show the event was the single greatest calamity ever to befall life on Earth, eclipsing even the extinction of…

The Guardian reports: On Sunday morning hundreds of politicians, government officials and scientists will gather in the grandeur of the International Congress Centre in Katowice, Poland. It will be a familiar experience for many. For 24 years the annual UN climate conference has served up a reliable diet of rhetoric, backroom talks and dramatic last-minute deals aimed at halting global warming. But this year’s will be a grimmer affair – by far. As recent reports have made clear, the world…

Air pollution is shaving years from people’s lives

Air pollution is shaving years from people’s lives

Comments 0 Comment

McClatchy reports: People could add years to their lives in California and other smog-plagued parts of the world if authorities could reduce particulate pollution — soot from cars and industry — to levels recommended by the World Health Organization, a new study reported Monday. No other large U.S. city would benefit more than Fresno, which has soot concentrations at roughly twice the WHO guidelines. Fresno residents would live a year longer if the region could meet the health organization’s recommended…

Humanity is ‘cutting down the tree of life’, warn scientists

Comments 0 Comment

The Guardian reports: Humanity’s ongoing annihilation of wildlife is cutting down the tree of life, including the branch we are sitting on, according to a stark new analysis. More than 300 different mammal species have been eradicated by human activities. The new research calculates the total unique evolutionary history that has been lost as a result at a startling 2.5bn years. Furthermore, even if the destruction of wild areas, poaching and pollution were ended within 50 years and extinction rates…

‘Hyperalarming’ study shows massive insect loss

The Washington Post reports: Insects around the world are in a crisis, according to a small but growing number of long-term studies showing dramatic declines in invertebrate populations. A new report suggests that the problem is more widespread than scientists realized. Huge numbers of bugs have been lost in a pristine national forest in Puerto Rico, the study found, and the forest’s insect-eating animals have gone missing, too. In 2014, an international team of biologists estimated that, in the past…
