Figure rises for second consecutive year, says Massachusetts’ top shark expert, warning of ‘public safety issue’ despite no deaths in state’s waters since 1936

Great white sharks are swimming toward the waters off Massachusetts in rising numbers, scientists say, after a second consecutive year showing an increase in predators to Cape Cod.

The latest data from a multiyear study of the ocean predators found that the number of sharks in waters off the vacation haven appeared to be on the rise, said Greg Skomal, a senior scientist with the Massachusetts division of marine fisheries, and the state’s top shark expert.

MPs condemn ‘waste of money’ as documents show controversial £2bn privatisation has cost taxpayers at least £1m in banking and legal fees

The troubled £2bn privatisation of the Green Investment Bank has already cost at least £1m of taxpayer money in consultancy fees, official documents have revealed.

Ministers have promised that the sale of the bank, which has invested in green projects from offshore windfarms to energy-saving street lights, will deliver value for taxpayers’ money. An announcement on the sale to Australian investment bank Macquarie was expected in January but has yet to materialise amid strong political opposition.

Manu National Park in Peru threatened by roads, oil/gas operations, narco trade, gold-mining, logging and ‘human safaris’

Just under half of UNESCO’s World Heritage sites are under threat, the WWF asserts. Sites deemed threatened include the Great Barrier Reef in Australia, the Pantanal in Brazil and the Virunga National Park in the Democratic Republic of Congo - and 111 others.

But what about the Manu National Park in Peru’s Amazon, which UNESCO calls the most biodiverse place on earth and was declared part of a biosphere reserve in the 1970s? In south-east Peru and stretching for 1.7 million hectares from the tropical Andes to the lowland forest, Manu is home to extraordinary biodiversity and Harakbut, Matsigenka, “Matsigenka-Nanti”, “Mashco-Piro”, Nahua, Quechua and Yine indigenous peoples.

Rapidly growing Canada goose population is health hazard but quarter of King’s students sign petition to spare the birds

It’s been an exacerbating week for Philip Isaac, domus bursar at King’s College, Cambridge University. It all started with an impassioned letter from students which, invoking the words of Gandhi, called for the peaceful coexistence of scholars and geese. It was only a matter of time before the press got wind of the petition. Journalists flocked to cover the story of the college that’s murdering its wildlife.

Trump administration’s zeal for deregulation seen by environmentalists as a recipe for fossil fuel cronyism, runaway climate change and toxic water crises

Scott Pruitt, administrator of the Environmental Protection Agency, caused conniptions among scientists this week by claiming that carbon dioxide isn’t the primary catalyst of global warming. Conservative groups and industry, on the other hand, heard hints that a cherished goal may be within reach.

In 2009 the EPA determined that greenhouse gas emissions “endanger both the public health and the public welfare of current and future generations”, opening the door to regulation. Donald Trump’s crusade against government strictures could target this finding, effectively making it official US policy that burning fossil fuels poses no threat to Americans, despite a mountain of scientific literature to the contrary.

South Uist Though we cannot see the hunters their presence is signalled by the waders that suddenly rise in flocks

Far in the distance the craggy peaks of Skye have been rendered Alpine-like by the overnight snow. Away to the north the high hills of Harris also bear a covering, and even South Uist’s less lofty heights have a dusting of white. There is a hint of warmth in the morning sun, but what makes this a glorious day to be outside is the complete absence of wind, for with even a light breeze it would be skin-flayingly cold.

We’re not the only ones to appreciate the calm, dry weather, for there are aerial predators abroad and the machair is full of birds for them to prey upon. Though we cannot see the hunters their presence is signalled by the groups of waders and starlings that suddenly rise in dense panicked flocks.

Our new study improves estimates of the rate of ocean warming - a critical component of climate change

New research has convincingly quantified how much the Earth has warmed over the past 56 years. Human activities utilize fossil fuels for many beneficial purposes but have an undesirable side effect of adding carbon dioxide to the atmosphere at ever-increasing rates. That increase - of over 40%, with most since 1980 - traps heat in the Earth’s system, warming the entire planet.

But how fast is the Earth warming and how much will it warm in the future? Those are the critical questions we need to answer if we are going to make smart decisions on how to handle this issue.

All of the methods of catching moles described in your article (The long read, 8 March) rely on the violent crushing of a sentient creature. Society wouldn’t tolerate killing a dog in this way, yet moles have a nervous system similar to dogs’ (and humans’), which strongly suggests they are capable of feeling pain and thus suffering. As the article indicates, the total cost of mole “damage” is very low but as it is part of the routine, casual cycle of killing practised by country dwellers we’re expected to accept it. All this because of a few piles of earth on a lawn.

The destruction of wildlife should be prohibited unless absolutely necessary – and only after there is evidence that damage is substantial, cannot be prevented by other intervention and that the killing can be done humanely.

The recent killing of a rhino in a Paris zoo marks a shocking new development in this ruthless global trade but rhino experts remain optimistic that the situation can be reversed

On the black market it is reputedly worth more than its weight in gold or cocaine, and this week the lure of rhino horn brought the bloody business of poaching to a zoo near Paris. There, in the dead of night, criminals broke in, shot a white rhino called Vince three times in the head and then hacked off its eight-inch horn with a chainsaw.

The attack marks a shocking new development in a crisis that sees more than three rhinos killed every day in their southern African homelands. Trade in rhino horn is completely illegal but demand from Vietnam and China fuels poaching and smuggling, putting the rhinos at risk of extinction.

In the remote Altai mountains, cameras traps are shedding light on the secret lives of these elusive animals, enabling researchers to identify individual leopards in the first ever nationwide census

The snow leopard is so rare and elusive that it’s commonly known as the “ghost of the mountains”. But researchers in the Altai mountains, where the borders of Russia, Mongolia, Kazakhstan and China converge, are increasingly coming face to face with this endangered animal through a growing network of camera traps.

On a recent day in Sailyugem national park in Russia’s Altai Republic, rangers in ski goggles and huge parkas were retrieving footage from a high-altitude camera trap – a black box holding a dozen AA batteries, a memory card and a motion-activated lens – nestled among a cluster of dark burgundy rocks covered with orange and green lichen. Such windswept ridges are where snow leopards typically travel in search of prey such as ibex and musk deer, sneaking down from above to break the victim’s neck with one crunch of their powerful jaws.

Ship ran aground at Raja Ampat, one of the country’s most popular dive sites that has been likened to an underwater Amazon, reports Mongabay

One of the main coral reefs at Raja Ampat, an Indonesian island chain home to perhaps the world’s richest marine biodiversity, was severely damaged last week when a Bahamian-flagged cruise ship smashed into it at low tide, according to an official report.

The 90-meter Caledonian Sky, owned by tour operator Noble Caledonia, ran aground in an uncharted shoal in West Papua province after completing a bird-watching trip on Waigeo Island on 4 March.

Cairngorms National Park We’ve tried to spot this mountain dwelling grouse in its white-feathered finery, but it’s elusive

Every birder has a “bogey bird”, a species they have repeatedly failed to encounter. For my father and me, this bird is the winter-plumaged ptarmigan.

We have made numerous visits to the Cairngorms in the hopes of seeing this mountain dwelling grouse – Lagopus mutus – in its white-feathered finery. But it has proved to be frustratingly elusive. Previous attempts have been foiled by extreme weather, from 90mph winds and whiteout conditions to horizontal rain and shrouding cloud.

Former Climate Change Authority member reveals what went on before he quit and offers a withering assessment of the PM

Clive Hamilton has been at the pointy end of public discourse on climate change for more than 20 years.

Among lots of other things, he’s written challenging books on the science, founded a progressive thinktank and had a failed crack at being an MP for the Greens.

Scott Pruitt, the new head of the US Environmental Protection Agency, gave an interview on CNBC on Thursday during which he denied carbon dioxide was a primary contributor to global warming. Pruitt also said that there is ‘tremendous disagreement’ over the extent to which human activity such as CO2 emissions are affecting the earth, despite widespread agreement in the scientific community

Trump adviser shocks scientists and environmental advocates with statement that negates EPA policy and ‘overwhelmingly clear’ evidence on climate change

Scott Pruitt, Donald Trump’s head of the US Environmental Protection Agency, has dismissed a basic scientific understanding of climate change by denying that carbon dioxide emissions are a primary cause of global warming.

Pruitt said on Thursday that he did not believe that the release of CO2, a heat-trapping gas, was pushing global temperatures upwards.

Images released by Greenpeace show newly bleached coral at reef between Port Douglas and Cairns

More evidence of coral bleaching on the Great Barrier Reef has emerged ahead of surveys that will confirm whether an underwater heatwave has caused widespread damage for an unprecedented second year in a row.

Photos and footage taken by marine biologist Brett Monroe Garner at a reef between Port Douglas and Cairns – south of the hardest-hit northern section of the reef last year – indicate severe bleaching of corals he said were “full of colour and life” just months ago.

Parents should protect their infants by using covers on prams during the school run, particularly in the morning, according to experts

Parents should use covers on their prams during the school run to protect their infants from air pollution, experts have warned.

Scientists tested the pollution levels inside prams to assess the exposure of infants taken on the school run with older siblings. The researchers found that the fine particle pollution from vehicle exhausts, which is particularly harmful, was higher during the morning journey.
