Elon Musk on Tuesday said he would reinstate former President Donald Trump’s Twitter account. 

The Tesla CEO who’s vying to buy Twitter and take it private for a reported price tag of $44 billion made the comment at the Financial Times Future of the Car conference. 

“I do think that it was not correct to ban Donald Trump,” Musk said. “I think that was a mistake because it alienated a large part of the country and did not ultimately result in Donald Trump not having a voice.”  

Musk added that Trump’s ban was “morally wrong and flat-out stupid.” 

Trump’s account was permanently banned after the January 6 riot at the U.S. Capitol, with Twitter saying his continued presence on the platform was a “risk of further incitement of violence.”  

Musk added that permanent bans should be “extremely rare” and reserved for “bots, or spam/scam accounts.”  

“Free speech is the bedrock of a functioning democracy, and Twitter is the digital town square where matters vital to the future of humanity are debated,” he said in a recent statement.  

Trump has said he does not intend to rejoin Twitter and will focus mostly on the social network he launched called Truth Social.

A new study led by the Marine Biological Association of the U.K. and the University of Southampton, along with experts in Australia and New Zealand, found that industrialized shipping could be killing large numbers of whale sharks.

Marine biologists have said that whale shark numbers have been falling in recent years, but it has not been clear why.

But a new international study suggests that collisions with shipping traffic could be a major factor.

Researchers examined satellite data to track about 350 whale sharks. They found that the world’s largest fish spend most of their time in waters used by freighters and other larger vessels.

The study showed that transmissions from the tags that monitor their movements often ended in busy shipping lanes. The international team, including experts from Britain, Australia and New Zealand, believe many sharks are probably being hit and killed by boats before sinking to the ocean floor.

Mark Erdmann is from the University of Auckland in New Zealand and a scientist at Conservation International, a non-profit environmental organization.

He co-authored the study, and believes shipping is a major threat to whale shark populations, which are a protected species.

“If we are protecting them from fisheries, why are their populations still declining? And one thought is the fact that these are big oceanic plankti vores that move relatively slowly, feeding on the surface, spend 50% of their time in, kind of, top 10-20 meters of the water. So, it is possible that they are actually running into a lot of the global shipping. Now, what the study found is that, indeed, there is a tremendous amount of overlap between where whale sharks are moving and global shipping traffic. So, those are real collision-risk areas,” he said.

Most lethal strikes are likely to go undetected or unreported. At present, there are no regulations to protect endangered whale sharks against these types of collisions.

Whale sharks play an important role in the marine food web and healthy ocean ecosystems.

They can grow up to 20 meters long.

The study is published in the PNAS — Proceedings of the National Academy of Sciences — journal.

The world is creeping closer to the warming threshold international agreements are trying to prevent, with a nearly 50-50 chance that Earth will temporarily hit that temperature mark within the next five years, teams of meteorologists across the globe predicted. 

With human-made climate change continuing, there’s a 48% chance that the globe will reach a yearly average of 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial levels of the late 1800s at least once between now and 2026, a bright red signal in climate change negotiations and science, a team of 11 different forecast centers predicted for the World Meteorological Organization late Monday. 

The odds are inching up along with the thermometer. Last year, the same forecasters put the odds at closer to 40%, and a decade ago it was only 10%. 

The team, coordinated by the United Kingdom’s Meteorological Office, in their five-year general outlook said there is a 93% chance that the world will set a record for the hottest year by the end of 2026. They also said there’s a 93% chance that the five years from 2022 to 2026 will be the hottest on record. Forecasters also predict the devastating fire-prone megadrought in the U.S. Southwest will keep going. 

“We’re going to see continued warming in line with what is expected with climate change,” said UK Met Office senior scientist Leon Hermanson, who coordinated the report. 

These forecasts are big picture global and regional climate predictions on a yearly and seasonal time scale based on long-term averages and state of the art computer simulations. They are different from increasingly accurate weather forecasts that predict how hot or wet a certain day will be in specific places. 

But even if the world hits that mark of 1.5 degrees above pre-industrial times — the globe has already warmed about 1.1 degrees (2 degrees Fahrenheit) since the late 1800s — that’s not quite the same as the global threshold first set by international negotiators in the 2015 Paris agreement. In 2018, a major United Nations science report predicted dramatic and dangerous effects on people and the world if warming exceeds 1.5 degrees. 

The global 1.5 degree threshold is about the world being that warm not for one year, but over a 20- or 30-year time period, several scientists said. This is not what the report predicts. Meteorologists can only tell if Earth hits that average mark years, maybe a decade or two, after it is actually reached because it is a long-term average, Hermanson said. 

“This is a warning of what will be just average in a few years,” said Cornell University climate scientist Natalie Mahowald, who wasn’t part of the forecast teams. 

The prediction makes sense given how warm the world already is and an additional tenth of a degree Celsius (nearly two-tenths of a degree Fahrenheit) is expected because of human-caused climate change in the next five years, said climate scientist Zeke Hausfather of the tech company Stripe and Berkeley Earth, who wasn’t part of the forecast teams. Add to that the likelihood of a strong El Niño — the natural periodic warming of parts of the Pacific that alter world weather — which could toss another couple of tenths of a degree on top temporarily, and the world gets to 1.5 degrees. 

The world is in the second straight year of a La Niña, the opposite of El Niño, which has a slight global cooling effect but isn’t enough to counter the overall warming of heat-trapping gases spewed by the burning of coal, oil and natural gas, scientists said. The five-year forecast says that La Niña is likely to end late this year or in 2023. 

The greenhouse effect from fossil fuels is like putting global temperatures on a rising escalator. El Niño, La Niña and a handful of other natural weather variations are like taking steps up or down on that escalator, scientists said. 

On a regional scale, the Arctic will still be warming during the winter at a rate three times more than the globe on average. While the American Southwest and southwestern Europe are likely to be drier than normal the next five years, wetter than normal conditions are expected for Africa’s often arid Sahel region, northern Europe, northeastern Brazil and Australia, the report predicted. 

The global team has been making these predictions informally for a decade and formally for about five years, with greater than 90% accuracy, Hermanson said. 

NASA top climate scientist Gavin Schmidt said the figures in this report are “a little warmer” than what NASA and the National Oceanic and Atmospheric Administration use. He also had doubts about skill level on long-term regional predictions. 

“Regardless of what is predicted here, we are very likely to exceed 1.5 degrees C in the next decade or so, but it doesn’t necessarily mean that we are committed to this in the long term — or that working to reduce further change is not worthwhile,” Schmidt said in an email.
