G7 agrees to phase out use of unabated coal power plants, and other nature and climate stories you need to read this week

Energy and climate ministers from the G7 group have agreed to phase out the use of coal power where the emissions have not been captured by 2035.

“It is a very strong signal from industrialized countries. It is a big signal to the world to reduce coal,” Italian minister and meeting chair, Gilberto Pichetto Fratin told The Guardian.

By referring to the unabated use of coal, the pledge leaves room for countries to keep burning coal to generate electricity, but only if power plants are fitted with carbon-capture technology to stop emissions.

This historic agreement was published just days after the US Environmental Protection Agency outlined a new directive that will require US coal-fired power plants to capture emissions or shut down.

Conservation measures are effective in halting the rapid loss of global diversity, a major international study has found.

Covering over a century of conservation action, the research team conducted the first-ever meta-analysis of 186 studies to compare the impact of global conservation interventions to what would have happened without them.

Conservation actions improved the state of biodiversity or slowed its decline in 66% of cases, compared with no action taken at all.

The positive impact of conservation action concluded that scaling conservation interventions up will be transformational in reversing biodiversity loss and reducing the effects of climate change. "Our results clearly show that there is room for hope", said study co-author and University of Oxford Associate Professor Joseph Bull.

Often described as the "nurseries of the sea", the world's estuaries are disappearing fast. Almost half of today's estuaries have been directly altered by humans, a new study finds.

Meanwhile, negotiations made slow but steady progress in the latest round of UN talks for a Global Plastics Treaty, in Ottawa, Canada. Delegates agreed on an advanced draft text of the legally binding instrument and on intersessional work to catalyse convergence on key issues. The final and fifth session of negotiations will take place in November this year in Busan, the Republic of Korea.

Scientists from the University of California San Diego, La Jolla. have developed a "self-digesting plastic" that could help reduce pollution. Self-eating bacteria spores are placed within the plastic, remaining dormant until exposed to nutrients in compost.

Globally, marine heat waves have spread across nearly 30% of the planet’s oceans, a surface area equivalent to all of North America, Europe, Asia and Africa. Multiple studies have found that increasingly frequent pulses of extreme heat are doing the most damage to marine ecosystems.

An international team of scientists has concluded that the recent drought in the Panama Canal was driven not by global warming, but by below-normal rainfall linked to El Niño.
