According to data released by the U.S. Department of Energy, carbon emissions from power generating plants in the United States fell by five percent last year, in addition to a five percent drop seen earlier in 2015. This decrease is the first one experienced in the more than forty years since record-keeping on CO2 emissions began, and in 2016 overall carbon emissions in the U.S. dropped by 1.7 percent, with emissions from vehicles now outpacing electrical generation.

Scientists have announced that a river in northern Canada has been dramatically re-routed due to the effects of global warming. Meltwater from the Yukon territory’s Kaskawulsh glacier, formerly flowing north into the Yukon River via the Slims River, now flows south into the Alsek River, emptying into the Pacific Ocean. The event underscores how rapidly potential changes can happen when systems that are affected by climate change reach their tipping points.

The continued thawing of Arctic permafrost is causing the accelerated release of previously-trapped methane deposits, as evidenced by both satellite imagery and findings made by field researchers in Siberia. Accumulated after having been produced by biological activity, these methane deposits have been frozen in the permafrost for millennia and are being released as the Arctic steadily warms due to climate change.

As President Trump moved to unwind Obama-era regulations designed to bring the US into compliance with the Paris Climate Accord, ExxonMobil, long a climate change denier, urged him not to abandon the climate accord. The company sent a letter to Trump’s top energy policy aid describing the agreement as "an effective framework for addressing the risks of climate change." Johnson & Johnson, Nike and Intel have also, among many others, signed a statement in support of the Paris agreement. When campaigning, Trump promised that the Paris agreement would be "cancelled" within a hundre days. He has describe global warming science as a plot created by the Chinese in order to render US manufacturing non-competitive.
