the Arctic is warming quickly, early-season heat waves abound, flooding in Yellowstone, green aluminum, is creating fossil-fuel PR immoral?
Recent measurements have documented that a region of the Arctic is warming faster than any place on Earth. The Guardian reports on these temperature increases on the islands of Svalbard and Franz Josef Land in the Barents Sea. That the Arctic would warm more rapidly relative to the rest of the planet has been predicted since the 1970s, due mainly to ice (that reflects solar radiation) being replaced by water (that absorbs solar radiation). However, the heating appears to be happening faster than previously estimated. This will likely have significant impacts on weather outside of the Arctic as the historical temperature gradient between the tropics and the Arctic gets smaller.
Water availability is declining in the western U.S. through a combination of drought, population growth and lack of conservation (John Oliver has a nice primer on the problem). This reduction can be seen in Utah as the Great Salt Lake dwindles in size. The New York Times examines the implications of this change, which extends far beyond the loss of water itself. In particular, the exposed lake bed is becoming an air-quality hazard for the region, and there is no indication yet that the growth in water use that’s driving this problem is being addressed. A similar problem has already played out at Owens Lake east of the Sierra Nevada mountains in California, which has resulted in the town of Keeler essentially being abandoned. An article in the Washington Post describes the potential for taps to go dry in the South African city of Gqeberha, due to climate change and inadequate water-system maintenance.
The Washington Post reports that the “immediate crises — among them war, spiking gas prices and an open-ended pandemic — are hindering the ability of leaders to take necessary action on the longer-term threats posed by climate change.” At our present rate of emissions, we will fly past the 1.5°C target by 2030. One leading climate scientist noted, “we know what we need to do, but we are not doing it yet.” An article in the New York Times describes the growing challenges facing countries in Asia due to climate change and extreme weather…
