The new species is also the largest giant waterlily on the planet, with leaves growing up to three metres in the wild

A giant waterlily grown at Kew Gardens has been named as new to science, in the first discovery of its type in more than a century.

Scientists at the south-west London garden suspected for decades there could be a third species of giant waterlily and worked with researchers in its native home in Bolivia to see if their thesis was correct.

People downstream from Wiseman’s Ferry urged to evacuate

Those in the low-lying areas of the Lower Hawkesbury downstream from Wiseman’s Ferry are ordered to evacuate by 10am today, per the SES:

I understand it’s school holidays, but really have a look at your travel plans, if you do have any. If you don’t need to leave home, please, you know, bunker down at home if it’s safe to do so. Obviously, we’ve issued about 70 evacuation orders, mostly in the Hawkesbury-Nepean area.

Funding model also criticised for letting factories ‘off the hook’ with planning decision due this week

The UK government has been criticised for exposing low-income households to the cost of building the Sizewell C nuclear power plant while letting factories “off the hook” as a crucial planning decision is due this week.

If given the green light, the government hopes to use a regulated asset base (RAB) funding model to finance the project, which is being proposed by the French energy firm EDF.

Boom clouded by supply chain disruption, a fragmented industry as well as ethical issues

“It’s hot,” says Steve Springett, a director of the renewable energy brand Egg, cheerily assessing the solar market. “There’s two key factors: people are understanding the environmental benefits of it better, and energy is really, really expensive at the moment.”

Consumer interest has increased in recent months as Britons hunt for ways to cut huge energy bills. A reduction in VAT on energy efficient systems from 5% to nothing this spring has added to the appeal of solar power.

Grunion run has fascinated scientists and locals for decades, but their future is threatened by the climate crisis

On certain nights on a quiet California beach, thousands of small, silvery fish gather in the moonlight to perform a unique mating ritual.

Known as the “grunion run”, the spectacle is one of the lesser known natural wonders of the US west coast. Grunion are a rare fish species that come ashore to spawn, and during the months of April to August they cover beaches from Baja California to Santa Barbara like a glittering carpet, wriggling in the sand to lay and fertilize eggs just after the highest tide of a full or new moon.

Party makes promise amid reports UK is falling behind European rivals in production capacity for EVs

Labour has pledged to create at least 30,000 jobs by promising to build three gigafactories for electric car battery production in Britain by 2025, as it warned the country was falling behind its European competitors in the race to ditch petrol power.

Amid recent reports that Britain faces a battle to hold on to the production of electric vehicles (EVs) made by manufacturers already in the UK, the party has committed itself to a major expansion of the part-financing of gigafactories. It follows research suggesting countries such as Germany, which already has a huge car industry, are significantly ahead in establishing the plants.

Policy would ban new ocean drilling but allow up to 11 lease sales in Gulf of Mexico and Alaska’s south coast

Joe Biden’s administration on Friday unveiled a five-year offshore oil and gas drilling development plan that blocks all new drilling in the Atlantic and Pacific Oceans within US territorial waters while allowing some lease sales in the Gulf of Mexico and Alaska’s south coast.

The plan, which has not been finalized, could allow up to 11 lease sales but gives the interior department the right to make none. It comes two days after the US supreme court curbed the power of the Environmental Protection Agency to respond to the climate crisis.

Methods of keeping living spaces warm range from cheap gap-sealing to expensive double-glazing, but the first step is to find and see the problem

It’s minus four degrees when scientist Jenny Edwards arrives to inspect my bitterly cold Canberra home. Huddled inside with a coffee, dressed for an ascent to Everest base camp, I’m fretting over whether she’ll make it past the front deck. It’s iced over again.

I’m breathing fog in the kitchen and frost has covered the bay window in my bedroom.

Training programmes for working dogs and pets are aimed at protecting the flightless bird’s dwindling numbers, but they come at a cost

Tip, a young hunting dog, pads up a goat track through New Zealand’s damp forest undergrowth, alert and excited as her nose hoovers the ground for smells. She stops suddenly to investigate an irresistible scent – the sweet, musty aroma of kiwi.

Tip is allowed a moment to inhale before a low-level electric pulse, issued from a collar, warns her that this bird is out of bounds. She briefly recoils, the electric signal enough to form an immediate negative association with the smell.

Sizewell C proposal will power 6m homes but could pose a threat to Minsmere nature reserve, the RSPB’s jewel in the crown

The Bittern Hide at the RSPB’s Minsmere reserve was doing steady business last Wednesday. More than a dozen birdwatchers were crammed into the elevated shelter which overlooks a broad band of heath, freshwater pools and reed beds stretching to the Suffolk coast. Marsh harriers swirled overhead and an occasional bittern swept across the landscape. In front of another nearby hide, avocets waded leisurely across a lagoon. Minsmere is an ornithologist’s paradise.

But a threat hangs over its wildlife glories. In a few days, the government is set to announce its decision on whether to allow the Sizewell C nuclear power plant to be built by EDF on land that overlooks the 1,000-hectare (2,500-acre) reserve.

When second world war-era storage tanks leaked into Hawaii residents’ water supply in December thousands got sick

Beginning in December, US army Major Amanda Feindt and her family found themselves in and out of Tripler army medical center in Honolulu. First, her husband for debilitating ocular migraines, then her four-year-old daughter, who was vomiting with severe abdominal pain, then her one-year-old for chemical burns, and later herself when she started experiencing crippling back pain that prevented her from being able to walk, among other troubling symptoms.

The Feindts were only four of thousands who reportedly sickened after 19,000 gallons of jet fuel from the US navy’s second world war-era underground fuel storage facility leaked into one of Oahu’s main drinking water aquifers. The contamination has led to a major water crisis in the Pacific, affecting more than 93,0000 people.

Worried about the proliferation of plastic trash in the environment and her own body, a journalist tried to shop plastic-free for 7 days. She found plastic in a lot of sneaky and surprising places.

The proposal brought immediate backlash from environmentalists who accused Biden of betraying the climate cause, while oil industry officials said it would do little to counter high energy prices.

Exclusive: António Guterres says growing north and south divide is ‘morally unacceptable’ and dangerous

Humanity is facing a “perfect storm” of crises that is widening inequality between the north and south, the UN secretary general has warned. The divide is not only “morally unacceptable” but dangerous, further threatening peace and security in a conflicted world.

The global food, energy and financial crises unleashed by the war in Ukraine have hit countries already reeling from the pandemic and the climate crisis, reversing what had been a growing convergence between developed and developing countries, António Guterres said.

The Supreme Court's ruling that curbs the power of the EPA will slow its ability to respond to the climate crisis, but "does not take the EPA out of the game," according to its administrator.

AspiraDAC device can remove two tonnes of CO2 a year and store it underground using direct air capture technology

A solar-powered and tent-sized Australian prototype machine that can suck CO2 from the air has secured a $700,000 contract to capture and store carbon.

The deal, part of a project backed by corporates including the owners of Google and Facebook, is thought to be the first time an Australian company has secured a deal to remove CO2 using direct air capture (DAC) technology.

Home energy assessor Adam Corrigan is knelt down by my rental property’s pool pump, and he’s not impressed.

Beside him, the pool and attached “spa” – a huge drawcard for Sydney’s trendy inner west – sits in all its share house glory, icy cold, with grime slowly multiplying.
