Breaking Waves: Ocean News

Delegates from 196 countries are discussing progress in preserving biodiversity. So what are the sticking points? Every two years, leaders from around the world gather to discuss the state of life on Earth, negotiating agreements to preserve biodiversity and stop the destruction of nature. This week, representatives of 196 countries are gathering in Cali, Colombia, for the 16th UN Conference of the Parties summit (Cop16). It is the first biodiversity-focused meeting since 2022, when governments struck a historic deal to halt the destruction of ecosystems. Scientists, Indigenous communities, business representatives and environment ministers from nearly 200 countries will discuss progress towards the targets and negotiate how they will be monitored. Here are the main things to look out for during the summit.

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 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. Continue reading...

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 former environment campaigner described as “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.
