The planet is now hotter than at any time in recorded human history, according to research conducted at Texas A&M University and published in the Royal Swedish Academy of Science’s magazine Ambio. Scientists Thomas Crowley and Thomas Lowery examined 15 different records of past climates from around the world, including ice cores from Tibet, tree rings in Colorado, old English shipping records, and ancient Chinese writings. Their findings support the widely held belief that human activity is causing the planet to heat up. Meanwhile, Oxfam has issued an urgent plea for international aid as a third year of drought threatens Afghanistan, India, and Pakistan, a heat streak that could relate to global warming.
