It might sound more like the kind of idle daydream billionaires like Elon Musk would have, but could flooding the Sahara actually be the best way of tackling climate change in the future? The idea of creating a new “sea” in Africa is being discussed, and it’s not the first time that the notion of a great oasis in the Sahara has been discussed among the scientific community. As the ongoing climate crisis continues to worsen, the notion of flooding vast areas of the desert is being returned to once again [via IFL Science]. A new “sea” was first proposed following the study of the Messinian salinity crisis – which saw a dried-out area of the Mediterranean rejuvenated by the Zanclean flood, reconnecting the Mediterranean Sea to the Atlantic Ocean around 5.33 million years ago. Sign up to our free Indy100 weekly newsletter Given how the Mediterranean was transformed by the flood, the idea of flooding the Sahara to achieve similar results has been thrown around in the scientific community as far back as 1877, the Scottish engineer Donald McKenzie suggested flooding the El Djouf basin in Western Africa. The idea is now returning to popularity as the world looks for solutions to the climate crisis. One proposal centres on the Middle East’s Dead Sea and flooding the area using water from the Red Sea to the Dead Sea Depression. A vast sea in Africa could represent a hugely innovative step towards tackling climate change and fostering a new hub of life – but even the people suggesting work such a project acknowledge just how expensive and dangerous it is. Even Y Combinator is a US startup accelerator who has described “desert flooding” as “risky, unproven, even unlikely to work”. Only time will tell whether the notion of a new sea in the Sahara coud ever work, or whether it’ll remain the stuff of dreams. Have your say in our news democracy.

Former House Speaker Nancy Pelosi (D-CA) said that former president Donald Trump exuded no bravado or confidence as he appeared in Washington DC for his arraignment on federal charges this week. Ms Pelosi led the House of Representatives during both of Mr Trump’s impeachments, first for his attempt to condition aid to Ukraine on newly elected President Volodymyr Zelensky investigating Joe Biden’s son Hunter, and then in 2021 for his actions during the January 6 insurrection. Mr Trump appeared at the E Barrett Prettyman Courthouse on Thursday and pleaded not guilty to four charges stemming from his attempt to overturn the 2020 presidential election results. During his arraignment, Mr Trump appeared to stumble over his words when asked to state his full name and appeared rather sombre compared to his other arraignments in New York and Miami. Ms Pelosi, who stepped aside from Democratic House leadership earlier this year after Republicans won the majority in the House of Representatives, told Andrea Mitchell on MSNBC that Mr Trump lacked the confidence and bravado usually associated with the ex-president. “I wasn’t in the courtroom, of course, but when I saw Trump coming out of his car and this or that, I saw a scared puppy,” Ms Pelosi said on Friday. “He looked very, very, very concerned about the fate. I didn't see any bravado or confidence or anything like that. He knows the truth, that he lost the election and now he has to face the music.” Ms Pelosi has largely avoided discussing the former president since he left office. During her farewell address as House speaker, she mentioned her work with former presidents George W Bush, a Republican, and Barack Obama, a Democrat, as well as President Joe Biden. But she did not mention Mr Trump. When the indictment was unsealed on Tuesday, Ms Pelosi credited the work of the January 6 select committee that commenced under her speakership for leading to the indictment. “Now, following the Justice Department’s further investigation, a federal grand jury has indicted the former President,” she said. “As this case proceeds through the courts, justice must be done according to the facts and the law.” Read More Trump pleads not guilty to federal conspiracy charges in plot to overturn 2020 election Trump appears to stumble over his name and age at arraignment
