'Swimming into the unknown:' Mexico's unmapped underwater caves - in pictures

Guardian Environment News - Wed, 2018/05/16 - 10:00pm

Photographer Klaus Thymann has been exploring the underwater cave system of the Yucatán peninsula, diving 1km underwater to where salt and freshwater meet. By mapping areas that have been untouched by modern civilisation, he hopes to raise awareness of the natural and human heritage of this unique ecosystem that will hopefully result in greater protection. He talks to Eric Hilaire about making his journey into a film, Flows, featuring music by Radiohead’s Thom Yorke

I am about to climb down a 10-metre rope ladder into a manhole-sized gap in the floor of the Mexican jungle on the Yucatán peninsula, to dive an underwater cave system, exploring paths where no one has ever been in modern history.

You may be familiar with cenotes, or sink holes, the beautiful wells filled with tempting blue water, but this hole does not look like that. Why would anyone want to head down there is a good question but we are exploring places where no one has been since the Mayans. This place doesn’t exist on any maps. My objective is to explore places with the view to bringing about environmental awareness, hopefully resulting in protection.

Retailer will give fresh produce to community groups two hours before stores close

The Co-op is to end “last-minute” sales of fresh produce to reduce the volume of edible food going to waste in its stores every day.

Two hours before closing time, the national supermarket chain will remove items with a use by or best before date for that day, so they can be donated to thousands of charities and small community groups in time for them to be frozen or turned into meals.

Pure Sine Wave

The Field Lab - Wed, 2018/05/16 - 12:56pm
Since I seem to be going soft in my old age, it was time for a little upgrade to my Frankenstein solar system.  Just tested out a new 3,000 watt pure sine wave inverter to run my 5,000 Btu air conditioner in the afternoon.  Although Pepino is still a real gem keeping me cool overnight into mid morning, it just can't keep up with my comfort zone in the blazing hot afternoons this time of year.  The test went flawlessly and my solar ran the AC just fine.  Up until now, I have had to run the AC for a couple of hours in the afternoon off my generator.  90,99,65,0,B

Mysterious rise in banned ozone-destroying chemical shocks scientists

Guardian Environment News - Wed, 2018/05/16 - 10:00am

CFCs have been outlawed for years but researchers have detected new production somewhere in east Asia

A sharp and mysterious rise in emissions of a key ozone-destroying chemical has been detected by scientists, despite its production being banned around the world.

Unless the culprit is found and stopped, the recovery of the ozone layer, which protects life on Earth from damaging UV radiation, could be delayed by a decade. The source of the new emissions has been tracked to east Asia, but finding a more precise location requires further investigation.

Water shortages to be key environmental challenge of the century, Nasa warns

Guardian Environment News - Wed, 2018/05/16 - 10:00am

Freshwater supplies have already seriously declined in 19 global hotspots – from China to the Caspian Sea – due to overuse, groundbreaking study shows

Water shortages are likely to be the key environmental challenge of this century, scientists from Nasa have warned, as new data has revealed a drying-out of swaths of the globe between the tropics and the high latitudes, with 19 hotspots where water depletion has been dramatic.

Areas in northern and eastern India, the Middle East, California and Australia are among the hotspots where overuse of water resources has caused a serious decline in the availability of freshwater that is already causing problems. Without strong action by governments to preserve water the situation in these areas is likely to worsen.

UK must secure billions in investment to meet climate targets, MPs warn

Guardian Environment News - Wed, 2018/05/16 - 3:47am

Influential committee says collapse in low-carbon investment is endangering jobs and threatening climate commitments

Investment in the UK’s low-carbon economy has fallen dramatically, endangering jobs and putting in doubt the government’s commitments on climate change, an influential committee of MPs has warned.

Funds going into renewable energy, the mainstay of the low-carbon economy, fell more than 50% in 2017, having dropped by 10% in 2016, bringing annual investment in the sector to its lowest since the financial crisis in 2008.

One man's race to capture the Rocky Mountains glaciers before they vanish

Guardian Environment News - Wed, 2018/05/16 - 3:00am

Garrett Fisher spent much of his summer in 2015 flying over places like Yellowstone taking stunning pictures of retreating glaciers

After hearing that the glaciers of the Rocky Mountains are rapidly vanishing, financial consultant Garrett Fisher took a novel course of action – he flew a light aircraft, built in 1949, low and alone over the mountains in order to photograph them.

Fisher spent much of his summer in 2015 flying over places such as Yellowstone, Glacier National Park and Grand Teton National Park, taking stunning pictures of retreating glaciers for a new book.

Glyphosate shown to disrupt microbiome 'at safe levels', study claims

Guardian Environment News - Wed, 2018/05/16 - 1:30am

Study on rats said to show that the chemical, found in Monsanto’s Roundup weedkiller, poses ‘a significant public health concern’

A chemical found in the world’s most widely used weedkiller can have disrupting effects on sexual development, genes and beneficial gut bacteria at doses considered safe, according to a wide-ranging pilot study in rats.

Glyphosate is the core ingredient in Monsanto’s Roundup herbicide and levels found in the human bloodstream have spiked by more than a 1,000% in the last two decades.

Leaked report warns Cambodia's biggest dam could 'literally kill' Mekong river

Guardian Environment News - Tue, 2018/05/15 - 11:00pm

Government-commissioned report says proposed site at Sambor reach is the ‘worst possible place’ for hydropower due to impact on wildlife

A Chinese-backed plan to build Cambodia’s biggest dam could “literally kill” the Mekong river, according to a confidential assessment seen by the Guardian which says that the proposed site at Sambor is the “worst possible place” for hydropower.

The report, which was commissioned by the government in Phnom Penh, has been kept secret since it was submitted last year, prompting concerns that ministers are inclined to push ahead regardless of the dire impact it predicts on river dolphins and one of the world’s largest migrations of freshwater fish.

Plantwatch: glyphosate is only way to manage Japanese knotweed

Guardian Environment News - Tue, 2018/05/15 - 1:30pm

Japanese knotweed is said to cost UK economy £170m a year, but so far only solution is controversial glyphosate-based herbicide

Japanese knotweed is a thug of a plant capable of growing a foot a week at this time of year; it spreads rapidly from underground rhizomes; erodes riverbanks, leading to flooding; smothers other plants; blocks drains and wreaks such havoc on homes and gardens that it blights property prices. It is estimated that controlling Japanese knotweed costs the UK economy about £170m each year. An entire industry has been built on trying to control the plant, using at least 15 different active control methods. There is, however, no impartial study of how effective any of these treatments are.

Scientists at Swansea University recently concluded the world’s largest field trial over five years on tackling Japanese knotweed. Their depressing assessment is that eradicating the plant using weedkillers is useless, and so too are physical methods such as covering up and cutting down knotweed.
