Breaking Boundaries: The Science of Our Planet shows the toll the demise of the Earth’s natural places is having on the people who study them

One of Australia’s leading coral reef scientists is seen breaking down in tears at the decline of the Great Barrier Reef during a new Sir David Attenborough documentary to be released globally on Friday evening.

Prof Terry Hughes is recounting three coral bleaching monitoring missions in 2016, 2017 and 2020 when he says: “It’s a job I hoped I would never have to do because it’s actually very confronting …” before tears cut him short.

Verra is considering developing a new independent agroforestry methodology in our VCS Program, given this limited agroforestry project activity. However, before initiating development, Verra needs to research existing methodologies with expert input to determine whether a new agroforestry methodology is actually needed.

Analysis shows significant risk of cascading events even at 2C of heating, with severe long-term effects

Ice sheets and ocean currents at risk of climate tipping points can destabilise each other as the world heats up, leading to a domino effect with severe consequences for humanity, according to a risk analysis.

Tipping points occur when global heating pushes temperatures beyond a critical threshold, leading to accelerated and irreversible impacts. Some large ice sheets in Antarctica are thought to already have passed their tipping points, meaning large sea-level rises in coming centuries.

The EU’s proposed carbon border adjustment mechanism (CBAM) will look like a ‘notional’ ETS and will give importers a transition phase to alleviate their burden, according to draft documents that give little indication over how the measure will interact with free allocation of carbon allowances to industry.

A right whale born today is expected to reach a total length about a meter shorter than one born 40 years ago, study finds

Whales in the North Atlantic are shrinking in size, researchers have found, with entanglements in fishing gear blamed for the steady decline in the length of the animals over recent generations.

On average, a right whale born today is expected to reach a total length about a meter shorter than one born 40 years ago, according to the new study. This is an average decline in length of about 7% during this period.

We asked the world’s press to commit to treating climate change as the emergency that scientists say it is. Their response was dispiriting

The TV newsman Bill Moyers likes to tell the story of how Edward R Murrow, the pre-eminent US broadcast journalist of his time, insisted on covering what became Germany’s invasion of Poland in 1939. Murrow’s bosses at CBS News had other priorities; they ordered Murrow’s reporters to cover dance competitions in Hamburg, Paris and London, explaining that Americans needed some happy news. Murrow wouldn’t do it. “It’ll probably get us fired,” he told his colleagues, but he sent his correspondents to the German-Polish border; they arrived just in time to witness Hitler’s tanks and troops roar into Poland. Suddenly, Europe was at war. And Americans heard about it because journalists at one of the nation’s most influential news outlets defied convention and did their jobs.

Governor Ron DeSantis has signed a $3.4bn deal to restore the freshwater preserve and Biden has earmarked funds to help

For years environmental groups warned the Florida Everglades, a vast 1.5m acre (607,000 hectare) subtropical preserve, may be doomed to extinction. Agricultural pollution, saltwater intrusion, and rampant real estate development had turned the waterways toxic and the state’s iconic environmental landmark was left to slowly choke to death. Perhaps until now.

A sweeping Everglades restoration effort decades in the making is finally seeing renewed optimism thanks to a cast of unlikely champions: Florida state Republicans. In April, Ron DeSantis, the governor, signed an agreement with the US Army Corps of Engineers to build a massive $3.4bn reservoir west of Palm Beach, which would help restore the flow of freshwater to the Everglades. Other state-funded projects to revitalize the region’s delicate ecosystem are already months ahead of schedule, DeSantis said.
