‘It was as if they didn’t even flinch,’ researcher says as study finds tiger sharks’ presence consistent before and during storm

Forecasters expect the Atlantic hurricane season that began this week to bring increasingly fierce storms to the US east coast. One notoriously fierce kind of shark, however, does not seem likely to be swimming for cover.

The sad state of affairs is that, since the end of the carbon price, much that is good for growth is bad for reducing our emissions

This week came the news that we had discovered how to reduce emissions at a rate needed to get to net-zero by 2050 without imposing an economy wide price on carbon.

All we needed was a worldwide pandemic. Simple.

Parts of the continent potentially face a decade of crisis. These two measures are more important than any other in avoiding it

There are so many good causes in the world it is often difficult to know where aid money should go. As leaders line up to attend the G7 summit in Cornwall, the most effective destinations for aid money have become clearer – a global vaccination programme and improving girls’ education.

This is especially true in sub-Saharan Africa, where so much can go wrong over the next 10 years – a population explosion, massive biodiversity loss, desertification, famine and mass migration to mention just a few – that unless we focus our efforts on vaccines and girls’ education, whatever is done to alleviate poverty or tackle the climate emergency will be threatened or even sabotaged in almost every other region of the world.

Rich countries can’t expect to be trusted on their climate promises if they fail the poorest on vaccines

It would only cost $50bn to ensure 40% of the world’s population is vaccinated by the end of the year, and 60% by the first half of 2022. This is a recent estimate from the IMF, the latest institution to join a chorus of voices calling for a global vaccination programme to bring Covid-19 under control. The IMF has highlighted the economic benefits of global vaccines, which would be huge. But there is another powerful reason for a worldwide campaign.

Vaccinating the world will be crucial if countries are going to act together to confront the climate crisis, which will require many of the same things as delivering vaccines: resources, innovation, ingenuity and a true partnership between rich and developing countries. The Cop26 climate conference in November will be an opportune moment for building this partnership. But to do so, rich countries need to deliver on their early promises to deliver global vaccines.

As UK prepares for environment push at G7 summit, letter asks richest to make climate charitable focus

The UK’s 100 richest families are being urged to commit £1bn over the next five years to tackle the climate emergency and halt the destruction of the natural world, as the world prepares for a big push on environmental issues at the G7 summit.

Each of the 100 richest families in the UK, and the 100 biggest charitable foundations, will receive a letter on Saturday asking them to make the climate and biodiversity crises a focus of their philanthropic efforts, in order to stave off pending disasters that would imperil all their other charitable efforts.

Speculators' California Carbon Allowance (CCA) positions surged for the third consecutive week as the group took out a larger position on the current vintage contract, while compliance entities’ short position grew over the period, according to US Commodity Futures Trading Commission (CFTC) data published Friday.

Voluntary emissions reduction (VER) prices must surge tenfold this decade to drive meaningful climate action, otherwise buyers risk being accused of greenwashing by purchasing carbon offsets too cheap to deliver genuine GHG cuts, according to research published Friday.

Fishing communities fear for future as oil, plastic and toxic chemicals devastate ecosystem

Until last week Lucien Justin, the chair of the Jude Watta fisheries committee in Wattala, near Sri Lanka’s capital, Colombo, lived a simple life. He and his wife ate two meals a day, and their small community of 90 fishers regularly supported each other with food and money. “If we fish, money comes. If not, we are left hungry,” he said.

After the worst maritime disaster in Sri Lanka’s history poisoned the waters near where he fishes, however, he fears even that simple life is now in dire danger. “People are scared. Even if we caught fish, they wouldn’t eat it because they think it’s poisonous,” he said.
