The assumption by regulators around the world that it is safe to use pesticides at industrial scales across landscapes is false, according to a chief scientific adviser to the UK government. The lack of any limit on the total amount of pesticides used and the virtual absence of monitoring of their effects in the environment means it can take years for the impacts to become apparent, say Prof Ian Boyd and his colleague Alice Milner in a new article.

A failing dam is causing "extremely dangerous" flooding on a Puerto Rico river in the wake of Hurricane Maria, authorities say.

In an appearance on Real Time with Bill Maher, astrophysicist Neil deGrasse Tyson challenged former GM executive — and ardent climate denier — Bill Lutz to make a bet. “You take all the scientists who author these papers, get them to pool their money and invest in companies that would benefit from global warming,” Tyson said. “And take all the people who are in denial of global warming, take all their money and invest in companies that would presume there is no global warming. And I would predict [the climate deniers] will all go broke in the next 50 years.”

The cities of San Francisco and Oakland are suing some of the world’s largest oil companies over climate change, joining an emerging legal effort to hold the fossil fuel industry accountable for the damages wrought by rising seas. The suits, filed separately in Superior Court in San Francisco and Alameda County and announced Wednesday, claim that a slate of oil, gas and coal producers not only caused the heat-trapping gases that drove sea level rise but knowingly did so, a challenge akin to litigation against big tobacco companies in the 1990s.
