New UK research predicts extremes of weather will hit food production

Global heating could bring many more bouts of severe drought as well as increased flooding to Africa than previously forecast, scientists have warned.

New research says the continent will experience many extreme outbreaks of intense rainfall over the next 80 years. These could trigger devastating floods, storms and disruption of farming. In addition, these events are likely to be interspersed with more crippling droughts during the growing season and these could also damage crop and food production.

At least 279 animals have been stranded, triple the usual figure, and 98% have died, prompting investigation

At least 279 dolphins have become stranded across much of the US Gulf Coast since the start of February, triple the usual number, and about 98% of them have died, scientists from the National Oceanic and Atmospheric Administration (Noaa) said.

Scientists will investigate whether lingering effects from the 2010 BP oil spill and more immediate effects from low salinity because of freshwater flowing from high rivers and a Louisiana spillway contributed to the deaths, said Teri Rowles, coordinator for Noaa fisheries’ marine mammal health and stranding response program.

A depressing picture of global power generation has coal still firmly on top. And in a vicious cycle, the very heatwaves and winter freezes high carbon emissions cause seem to be increasing them

The world’s largest sovereign wealth fund is preparing to leave fossil fuels behind. Last week, Norway’s parliament confirmed by unanimous vote that its $1tn sovereign wealth fund would dump $13bn of fossil fuel investments – and start investing billions in renewables.

The move is designed to protect Norway’s state-owned investment fund from the decline in fossil fuels that will be vital if full-blown climate catastrophe is to be averted.

Yorkshire dairy by-products will be turned into renewable biogas to cut carbon emission

The crumbly cheese beloved of TV duo Wallace and Gromit will soon help heat thousands of Yorkshire homes with renewable “green gas” made from cheese waste.

The Wensleydale Creamery has struck a deal to supply the waste whey from its cheese factory to a local bioenergy plant that produces enough renewable biogas to heat 4,000 homes. The Leeming biogas plant, which currently runs on ice-cream residue, will use a process called anaerobic digestion to turn the dairy-based waste into renewable biogas.

The U.S. and Canada are under pressure to show a water control plan for the area along Lake Ontario and the St. Lawrence River didn't actually make flooding worse.

Shift from fossil fuels top of agenda for Paris air show, industry having lagged behind other sectors

Faced with growing calls for action on the climate crisis, aerospace companies gathering for the Paris air show next week are turning their thoughts to a future run on electricity rather than fossil fuels.

The scale of the challenge is considerable. The target for net zero carbon emissions by 2050, recommended by the Intergovernmental Panel on Climate Change and embraced by the UK this week, coincides with the expectation that the number of flights will double in the next 20 years.

Group defies court order against Arctic Sunrise supporting occupation of North Sea rig

Police have arrested two Greenpeace activists who had boarded a North Sea oil rig as the environmental group said it was sending its ship Arctic Sunrise to join the protest in defiance of court orders obtained by BP.

The oil firm has taken out injunctions against the ship and the Greenpeace ice-breaker, the Esperanza, forbidding them from supporting a protest on a rig in Scotland’s Cromarty Firth that is now in its sixth day.

Addressing energy leaders, pope warns of ‘catastrophic’ effects of global heating

Pope Francis has declared a global “climate emergency”, warning of the dangers of global heating and that a failure to act urgently to reduce greenhouse gases would be “a brutal act of injustice toward the poor and future generations”.

He also endorsed the 1.5C limit on temperature rises that some countries are now aiming for, referring to warnings from the Intergovernmental Panel on Climate Change of “catastrophic” effects if we crossed such a threshold. He said a “radical energy transition” would be needed to stay within that limit, and urged young people and businesses to take a leading role.

William Happer contacted Heartland Institute, one of the most prominent groups to dispute that fossil fuels cause global heating

A member of the Trump administration’s National Security Council has sought help from advisers of a conservative thinktank to challenge the reality of a human-induced climate crisis, a trove of his emails show.

William Happer, a physicist appointed by the White House to counter the federal government’s own climate science, reached out to the Heartland Institute, one of the most prominent groups to dispute that burning fossil fuels is causing dangerous global heating, in March.

Scottish Power claims it is making a ‘significant step’ forward with renewable energy, but David Miller has doubts

Jillian Ambrose (Report, 11 June) claims that a 50MW battery system is a “significant step”. But how significant a step does not depend upon the instantaneous energy output in megawatts. Most significantly, it depends on how long it can keep this energy flow going. So the relevant measurement, to compare with rival systems, would be in MW hours (which are what we pay for in our electricity bills).

Natural England chair bemoans budget cuts that have left conservation body ‘massively depleted’

The reserves and protected places that are the “jewels in the crown” of English nature cannot be managed properly because of budget cuts, Tony Juniper, the chair of Natural England, has said.

The budget for the government’s conservation watchdog has been slashed in half over five years, leaving it “massively depleted”, according to Juniper, the influential former Friends of the Earth campaigner whom the environment secretary, Michael Gove, appointed earlier this year.

The ‘sunshine tax’ is dead, and Barcelona and Cádiz are mounting a renewables revival

After a close fight, Barcelona’s radical mayor, Ada Colau, is expected to take office for a second term on Saturday, vindicating her often-criticised policies, which have included making sure all the city’s municipal buildings and services run on renewable energy.

On the other side of the country in Andalucía, José María González was re-elected as mayor of Cádiz last month having swept to power in 2015 on the same tide that brought Colau to office, with energy as a central issue in his campaign.

The pipeline poses grave risk to animals and Indigenous communities. As leaders of four sovereign tribes, we are calling on the government to say no

In February, Canada’s National Energy Board released its final report recommending approval of the Trans Mountain pipeline expansion, in spite of devastating risks to the Salish Sea and the salmon, orca and tribal nations that rely on it. On 18 June, the government of Justin Trudeau is expected to issue its final decision.

The Trans Mountain pipeline, first proposed by oil giant Kinder Morgan in 2013, would transport Alberta tar sands oil to a shipping terminal in Vancouver, British Columbia. This would mean a massive increase in oil tanker traffic through the Salish Sea, which comprises the water bodies of Puget Sound, the Strait of Juan de Fuca and the Strait of Georgia. The marine species in these waters know no border, and the risks to Indigenous peoples in both Canada and the US also cross borders. As leaders of four sovereign tribes, we are calling on the Trudeau government to do the right thing and say no.

The state has just had its warmest spring on record, causing permafrost to thaw and dramatically reshaping some areas

A city in western Alaska has lost a huge stretch of riverbank to erosion that may turn it into an island, amid renewed warnings from scientists over the havoc triggered by the accelerating melting of the state’s ice and permafrost.

Residents of the small city of Akiak were alarmed to find the Kuskokwim River suddenly much closer to housing after about 75-100ft of riverbank disappeared over the course of just a few hours.
