"We looked out into the future, and [100th Meridian] continues moving eastward because of human-driven climate change. Climate change in the central US is of enormous importance to food security across the world,” says LDEO climate scientist Richard Seager. Via Marketplace. https://bit.ly/4rRBHFN
The Dry Line
It’s moving east. What does that mean for farmers and the world?

With temps breaching the Paris limit, cutting methane could buy crucial time such as by improving water, fertilizer, and soil management in rice production, and better livestock feeding and breeding practices, says LDEO soil systems scientist Yushu Xia. Via The Guardian. https://bit.ly/44jnebh
Can methane cuts pull us back from the brink of climate breakdown?
With temperatures breaching the Paris limit, experts say tackling the powerful gas could buy crucial time as the clean-energy shift stalls
