White House approves Tennessee’s state of emergency request as further fatalities expected to be confirmed

Violent storms and tornadoes have torn across the US south and midwest, killing at least seven people and downing power lines and trees, smashing homes and upturning cars across multiple states.

The outbreak of storms and tornadoes has resulted in at least seven deaths in Tennessee and Missouri, with further fatalities expected to be confirmed. One of the victims has been named: a 68-year-old man named Garry Moore who was a fire chief in Cape Girardeau county, Missouri. At least a dozen injuries have also been reported from the storms.

Reports predict global heating will bring catastrophes and that air conditioning market could grow by 41%

The world is on track for disastrous global heating – but this will create profits for some air conditioning companies, according to forecasts by leading Wall Street financial institutions.

Recent reports by Morgan Stanley, JPMorgan Chase and the Institute of International Finance all make clear the finance sector considers the Paris climate agreement limiting global temperatures, signed a decade ago by nearly 200 nations, is effectively dead and investors should plan accordingly.

Latest security flap again focuses scrutiny on Waltz after he earlier added journalist to Yemen war-planning chat

Michael Waltz, the embattled national security adviser to Donald Trump, and other members of the national security council have reportedly used personal Gmail accounts to conduct government business.

The apparent use of Gmail, a relatively insecure method of communication for high-level government officials, places further scrutiny upon Waltz, who is already under pressure after adding a journalist to a group chat on the commercial Signal app, where top US officials then planned and celebrated a US airstrike in Yemen last month.

The hardy travellers can fly for 3,000 miles from the north-east US and Canada to roost in their millions in Mexico

• More invertebrate of the year nominations

Imagine your body was the weight of a raisin, supported by just a pair of flimsy, gossamer wings. Now imagine that you had to fly for 3,000 miles, avoiding storms, highways and predators, to ensure your species continued.

Could you do it? Unless you’re a monarch butterfly, fortunately you won’t have to face such a challenge.

Between 24 March and 2 April, we will be profiling a shortlist of 10 of the invertebrates chosen by readers and selected by our wildlife writers from more than 2,500 nominations. The voting for our 2025 invertebrate of the year will run from midday on Wednesday 2 April until midday on Friday 4 April, and the winner will be announced on Monday 7 April.

US climate agency upended as Doge efforts to slash federal government compromise email security

A sense of chaos has gripped the National Oceanic and Atmospheric Administration (Noaa), one of the world’s premier research agencies, with key staff hastily fired and then rehired, cuts to vital weather forecasting operations and even a new, unsecured server that led to staff being deluged by obscene spam emails.

Noaa is currently being upended by Donald Trump’s desire to slash the federal government workforce, with more than 1,000 people already fired or resigning from the agency and 1,000 more staffers are expected to be removed as the purge continues. In total, this represents around 20% of the Noaa’s workforce.

In speech that began Monday night, Democratic senator warns of ‘grave and urgent’ danger of Trump administration

Cory Booker, the Democratic US senator from New Jersey, has broken the record for longest speech ever by a lone senator – beating the record first established by Strom Thurmond, who filibustered for 24 hours and 18 minutes in opposition to the Civil Rights Act of 1957.

Booker’s speech eventually ran to 25 hours and five minutes. Having begun at 7pm on Monday night, was not a filibuster but instead an effort to warn of what he called the “grave and urgent” danger that Donald Trump’s presidential administration poses to democracy and the American people.

Perhaps the most awe-inspiring of over 2,000 species is the amber comet, thought to only remain in Texas and Mexico

• More amazing nominations for invertebrate of the year

If invertebrates are mostly unheralded workers that keep life on Earth ticking over, then fireflies are the rare flamboyant stars that help make that life worth living. They are Elton John in platform shoes and outlandish glasses at his piano, they are Sabrina Carpenter in a glamorous dress as she drops her towel on stage.

Much like a Hollywood starlet who lounges around all day in a dressing gown eating crisps only to emerge later in stunning fashion on the red carpet, fireflies are creatures of the night, where their spectacular light shows both enchant and confound us.

Between 24 March and 2 April, we will be profiling a shortlist of 10 of the invertebrates chosen by readers and selected by our wildlife writers from more than 2,500 nominations. The voting for our 2025 invertebrate of the year will run from midday on Wednesday 2 April until midday on Friday 4 April, and the winner will be announced on Monday 7 April.

US president receives bipartisan criticism after saying there are ‘methods’ he could defy constitution to seek third term

• US politics live – latest updates

Donald Trump’s suggestion that there are “methods” by which he could run for a third term as US president has been met with scorn – but also warnings that he could seriously attempt it, despite being explicitly barred from doing so by the US constitution.

“The biggest mistake of the last eight years is that we somehow failed to give credibility to Donald Trump’s whims and impulses, but we know it’s true,” David Jolly, a former Republican member of Congress, told MSNBC.

We asked 18 Republicans whose districts benefit most from Biden’s IRA climate law if they back Trump’s demands

Billions of dollars in clean energy spending and jobs have overwhelmingly flowed to parts of the US represented by Republican lawmakers. But these members of Congress are still largely reticent to break with Donald Trump’s demands to kill off key incentives for renewables, even as their districts bask in the rewards.

The president has called for the dismantling of the Inflation Reduction Act – a sweeping bill passed by Democrats that has helped turbocharge investments in wind, solar, nuclear, batteries and electric vehicle manufacturing in the US – calling it a “giant scam”. Trump froze funding allocated under the act and has vowed to claw back grants aimed at reducing planet-heating pollution.

Gene Likens, who first identified acidic rainwater in 1960s, said the Trump administration’s ‘rollbacks are alarming’

The US could be plunged back into an era of toxic acid rain, an environmental problem thought to have been solved decades ago, due to the Donald Trump administration’s rollback of pollution protections, the scientist who discovered the existence of acid rain in North America has warned.

A blitzkrieg launched by Trump’s Environmental Protection Agency (EPA) on clean air and water regulations could revert the US to a time when cities were routinely shrouded in smog and even help usher back acid rain, according to Gene Likens, whose experiments helped identify acidic rainwater in the 1960s.
