Global emissions of the potent greenhouse gas methane hit an all-time high in 2017, according to a pair of new studies released this week by researchers with the Global Carbon Project. Agriculture, landfill waste and fossil fuel production are driving the sharp increase in methane emissions from human activities, reports Maria Temming of Science News.

Seventy years ago, American chemist Willard Libby devised an ingenious method for dating organic materials. His technique, known as carbon dating, revolutionized the field of archaeology.
Heat waves in areas of the Arabian Peninsula and Iran could get worse by 2100—a lot worse. If nothing is done to limit greenhouse gas emissions, simulations show that some Middle Eastern cities could experience a never-before-seen combination of temperature and humidity that would be beyond the limit of human survival.
Putting food on the table is one of the most basic human endeavors, and we’ve funneled plenty of innovation and ingenuity into the task. Farming is so intrinsic to our existence that some scientists think we can peg the start of the Anthropocene, the Age of Humans, to the dawn of agriculture some 11,700 years ago.
