Natural range of critically endangered western swamp tortoise increasingly untenable owing to reduced rainfall
Twenty-four of Australia’s rarest tortoises have been released outside their natural range because climate change has dried out their remaining habitat.
The natural range of the critically endangered western swamp tortoise, Pseudemydura umbrina, has shrunk to two isolated wetlands in Perth’s ever-growing outer suburbs, and a herpetological expert, Dr Gerald Kuchling, said reduced rainfall and a lowered groundwater table made those areas increasingly untenable.

Coastal village of Shishmaref, which is losing ground to rising sea levels, could become the first in the US to move over the threat of climate change
The residents of an Alaskan coastal village have begun voting on whether to relocate because of rising sea levels.
If they vote to move, the village of Shishmaref, just north of the Bering Strait, and its population of 650 people, could be the first in the US to do so because of climate change.

Australia is renowned for its iconic wildlife. A bilby digging for food in the desert on a moonlit night, a dinosaur-like cassowary disappearing into the shadows of the rainforest, or a platypus diving for yabbies in a farm dam. But such images, though evocative, are rarely seen by most Australians.
As mammalogist Hedley Finlayson wrote in 1935:
The mammals of the area are so obscure in their ways of life and, except for a few species, so strictly nocturnal, as to be almost spectral.
For some species, our time to see them is rapidly running out. We know that unfortunately many native animals face considerable threats from habitat loss, introduced cats and foxes, and climate change, among others.
More than ever before, we need accurate and up-to-date information about where our wildlife persists and in what numbers, to help ensure their survival. But how do we achieve this in a place the sheer size of Australia, and with its often cryptic inhabitants?

Fortunately, technology is coming to the rescue. Remotely triggered camera traps, for example, are revolutionising what scientists can learn about our furry, feathered, scaly, slippery and often elusive friends.
These motion-sensitive cameras can snap images of animals moving in the environment during both day and night. They enable researchers to keep an eye on their study sites 24 hours a day for months, or even years, at a time.
The only downside is that scientists can end up with millions of camera images to look at. Not all of these will even have an animal in the frame (plants moving in the wind can also trigger the cameras).
This is where everyday Australians can help: by becoming citizen scientists. In the the age of citizen science, increasing numbers of the public are generously giving their time to help scientists process these often enormous datasets and, in doing so, becoming scientists themselves.

Simply defined, citizen science is members of the public contributing to the collection and/or analysis of information for scientific purposes.
But, at its best, it’s much more than that: citizen science can empower individuals and communities, demystify science and create wonderful education opportunities. Examples of successful citizen science projects include Snapshot Serengeti, Birds in Backyards, School Of Ants, Redmap (which counts Australian sealife), DigiVol (analysing museum data) and Melbourne Water’s frog census.
Through the public’s efforts, we’ve learnt much more about the state of Africa’s mammals in the Serengeti, what types of ants and birds we share our cities and towns with, changes to the distribution of marine species, and the health of our waterways and their croaking inhabitants.
In a world where there is so much doom and gloom about the state of our environment, these projects are genuinely inspiring. Citizen science is helping science and conservation, reconnecting people with nature and sparking imaginations and passions in the process.
Australian wildlife in the spotlightA fantastic example of this is Wildlife Spotter, which launched August 1 as part of National Science Week.
Researchers are asking for the public’s help to identify animals in over one million camera trap images. These images come from six regions (Tasmanian nature reserves, far north Queensland, south central Victoria, Northern Territory arid zone, and New South Wales coastal forests and mallee lands). Whether using their device on the couch, tram or at the pub, citizen scientists can transport themselves to remote Australian locations and help identify bettongs, devils, dingoes, quolls, bandicoots and more along the way.

By building up a detailed picture of what animals are living in the wild and our cities, and in what numbers, Wildlife Spotter will help answer important questions including:
How many endangered bettongs are left?
How well do native predators like quolls and devils compete with cats for food?
Just how common are common wombats?
How do endangered southern brown bandicoots manage to survive on Melbourne’s urban fringe in the presence of introduced foxes, cats and rats?
What animals visit desert waterholes in Watarrka National Park (Kings Canyon)?
What predators are raiding the nests of the mighty mound-building malleefowl?
So, if you’ve got a few minutes to spare, love Australian wildlife and are keen to get involved with some important conservation-based science, why not check out Wildlife Spotter? Already, more than 22,000 people have identified over 650,000 individual animals. You too could join in the spotting and help protect our precious native wildlife.

World's hottest month shows challenges global warming will bring
July was hotter than any month globally since records began – but some areas, such as the Middle East, suffer more than others
In Siberia, melting permafrost released anthrax that had been frozen in a reindeer carcass for decades, starting a deadly outbreak. In Baghdad, soaring temperatures forced the government to shut down for days at a time. In Kuwait, thermometers hit a record 54C (129F).
July was the hottest month the world has endured since records began in 1880, scientists have said, and brought a painful taste of the troubles people around the world may have to grapple with as global warming intensifies. Results compiled by Nasa showed the month was 0.84C hotter than the 1951-1980 average for July, and 0.11C hotter than the previous record set in July 2015.

Second phase of new benchmark will cut equivalent of greenhouse gases emitted by electricity and power from all US residences in one year, officials say
US trucks will produce 10% less carbon dioxide and consume 10% less fuel within a decade under the last major plank of Barack Obama’s climate policy.
The second phase of a new benchmark for medium- and large-sized trucks will cut more than 1bn metric tonnes of carbon dioxide emissions and 2bn barrels of oil use, the Environment Protection Agency announced on Tuesday.

Simon Jenkins writes that “To question China’s good intentions in financing the power station [at Hinkley Point] is silly. It is a French-built plant, and the idea that Beijing might contrive to embed and then activate some doomsday bug is absurd” (Trade with China is a good thing. But Hinkley Point is a dud, 11 August).
Not that absurd. The China General Nuclear Group (CGN), which is involved in financing Hinkley Point, expects to build a new nuclear station with its own reactor at Bradwell in return for its involvement at Hinkley. This was agreed by David Cameron and Xi Jinping last October.

Researchers have captured rare footage of the stubby squid – a purple-colored species with large eyes – during an exploration voyage off Santa Monica, California. The somewhat rare species, which looks like a cross between an octopus and squid, spends its life on the seafloor, burrowing into the sand for camouflage and using its large eyes to spot incoming prey, such as shrimp and small fish

High pesticide levels on oilseed rape crops harm wild bees, scientists prove
Species that feed most on the bright yellow flowers of the crop treated with controversial neonicotinoids have fallen by as much as 30%
Pesticides used on oilseed rape crops, whose bright yellow flowers have become an increasingly common sight across the British countryside, are harming native populations of wild bees, scientists have conclusively proved.
Species that feed most on the flowers of the now-profitable cash crop used for vegetable oils and animal fodder are down by as much as 30%, according to the wide-ranging study published in the journal Nature.

Disasters like Louisiana floods will worsen as planet warms, scientists warn
National Oceanic and Atmospheric Administration to classify disaster as the eighth flood considered to be a once in every 500-year event in the US in a year
The historic and devastating floods in Louisiana are the latest in a series of heavy deluges that some climate scientists warn will become even more common as the world continues to warm.
On Tuesday, the National Oceanic and Atmospheric Administration (Noaa) is set to classify the Louisiana disaster as the eighth flood considered to be a once in every 500-year event to have taken place in the US in little over 12 months.

Amazon chiefs visit British Museum as part of dam-building protest
Leaders of the Munduruku people will be shown the storeroom’s head-dresses and other objects made by their tribe more than 150 years ago
Amazonian leaders, in Britain to protest against the construction of several large dams which they say will destroy the lives of thousands of indigenous people, will on Tuesday be shown head-dresses and other objects made by their tribe more than 150 years ago.
The two chiefs of the Munduruku civilisation, which has flourished peacefully for centuries by fishing and farming along the banks of the great Tapajós river and its tributaries in the rainforests of central Brazil, will visit the massive storeroom of the British Museum in London, where a collection of 50 objects brought to Britain by a Victorian merchant are kept.
