A Japanese blue carbon hopeful has set its sights on Dec. 2025 as the date by which it expects to gain J Blue credit certification for its seaweed farming project, though has made no mention of the numbers of credits it plans to generate.

Solar power will grow four-fold by 2030, overtaking nuclear, hydro and gas, and then coal by 2033. By 2050, it will produce more than all these technologies combined.

Oscar, 10th hurricane of 2024 season, batters Turks and Caicos and Bahamas and threatens Cuba and Canada

Hurricane Oscar has become the 10th hurricane of the 2024 Atlantic season, battering the Turks and Caicos Islands on Saturday night and the far southern Bahamas on Sunday.

The disturbance that eventually became Oscar was initially given a low chance of tropical development by the US National Hurricane Center. It began on 10 October as a tropical wave across western Africa, bringing thunderstorms and gusty winds to the Cabo Verde Islands, before moving westwards over the Atlantic. However, it struggled to become sufficiently organised at it progressed, as dry air inhibited further thunderstorm development.

Exclusive: Researchers find 61% of fresh waters in the UK contain high levels of phosphate and nitrate

The UK’s rivers contain a cocktail of chemicals and stimulants including caffeine, antidepressants and painkillers from water company sewage releases, polluting freshwaters at levels which can pose a risk to aquatic life, testing has found.

Results from three days of testing in rivers by 4,531 volunteers for the environmental research group Earthwatch showed that, in addition to the chemical mix in rivers, 61% of fresh waters in the UK were in a poor state because of high levels of the nutrients phosphate and nitrate, the source of which is sewage effluent and agricultural runoff. England had the worst level of poor water quality in rivers, with 67% of freshwater samples showing high levels of nitrate and phosphate.

Of the 91 samples already analysed, 100% contained caffeine, with levels in 80% of these samples presenting some risk to aquatic life, said Woods.

Nicotine was found in 25% of samples, with concentrations that present some risk to aquatic life found in 7% of samples. The antidepressant venlafaxine was found in 30% of samples analysed, with 13% of samples containing levels that posed a risk to aquatic life.

The antibiotic trimethoprim was found in 10% of samples, all at concentrations that posed some level of risk to aquatic life.

Diclofenac, a non-steroidal anti-inflammatory drug, was in 11 % of samples, all of which showed some level of risk.

In 5% of samples, the fungicide tebuconazole was present as a result of agricultural runoff.

The neonicotinoid acetamiprid, used for pet flea treatment, was present in 19% of samples, all showing some level of risk to aquatic life.

Earthwatch said the results showed the strong contribution that citizen science played in presenting a clearer picture of the health of rivers.

Ruth Davis named special representative for nature ‘to put climate and nature at the heart of our foreign policy’

The government has appointed the UK’s first envoy for nature, a role that a former campaigner called “the environmentalist’s environmentalist”, who will be charged with forging global agreement on halting the precipitous decline of species.

Ruth Davis, the new special representative for nature, is in Colombia for the start of two weeks of vital talks that will decide the global response to the biodiversity crisis. The UK has played a leading role in such efforts in the past and Davis helped draw up a global pledge on deforestation that was one of the main outcomes of the UN Cop26 climate summit hosted in Glasgow in 2021.

It has been a nightmare season for farmers, with England said to have had its second-worst harvest on record

Giant orange pumpkins with ghoulish grins have become a Halloween doorstep tradition but this year trick-or-treaters may be greeted with even spookier green-tinged jack-o-lanterns after a nightmare season for growers.

In Asda, pumpkin displays have signs telling shoppers “don’t worry if I’m slightly green, I will ripen at home and turn orange”.

We need to deal with the climate effects of global capitalism the way we deal with inflation – by applying the brakes

The impact of the climate crisis is evident everywhere. Finance ministers meet in Washington DC this week for the annual meeting of the International Monetary Fund in the wake of two devastating hurricanes in the US within a month. Parts of the Sahara have been flooded for the first time in half a century.

Scientists attribute the growing number of extreme weather events to a planet that continues to get hotter as the result of rising concentrations of greenhouse gases linked to human activity. Global temperature records are being broken with every year that passes and the idea that this can continue indefinitely is a fantasy.
