By Damian Carrington , The Guardian.  Excerpt: ...the most effective action individuals can take ...Most experts (76%) backed voting for politicians who pledge strong climate measures, where fair elections take place . ...The second choice for most effective individual action, according to the experts, was reducing flying and fossil-fuel powered transport in favour of electric and public transport. ...Globally it is a small minority of people who drive aviation emissions, with only about  one in 10 flying at all . Frequent-flying “super emitters” who represent just 1% of the world’s population cause half of aviation’s carbon emissions, with US air passengers having by far the biggest carbon footprint among rich countries. ...Meat production has a  huge impact   on the environment . Most people in wealthy countries already eat more meat than is healthy for them and more than 60% of the scientists said they had cut their own meat consumption. Almost 30% of the ex...

Experts say that isn’t sustainable. ,...Every five years, the Department of Agriculture and the Department of Health and Human Services jointly publish a new version of the  guidelines . They form the basis for the public-facing eating guide  MyPlate , formerly  MyPyramid , as well as many government-backed meal programs, such as National School Lunch. Historically, these guidelines have narrowly focused on human nutrition, but some are now saying they should be expanded to incorporate climate considerations as well. ...The current, 150-page edition for 2020-2025 doesn’t mention food’s role in the climate crisis at all. Climate groups say this is an abdication of responsibility, with Americans feeling the effects of a warming planet more than ever. ...A sustai...

For the world to have a chance of preventing significant harm from climate change, the study authors say, all parts of food production need rapid and significant reform—everything from reducing deforestation for new fields to eating less meat. ...Carbon dioxide comes from many sources, such as cutting down tropical forests to make way for fields and pastures, running farm machinery, and manufacture of agrochemicals. Fertilizer also emits nitrous oxide, another greenhouse gas. And cows release methane, a powerful warming gas, in their burps and manure. ...The team assumed no radical chan...
