Memorial Day marks the unofficial beginning of summer in the United States as the temperate breezes of spring give way to an enveloping heat that has become more and more intense each year due to climate change. This summer forecasters are expecting two big things: deadly heat and electricity outages. Mainstream news coverage is now explaining why these are inextricably intertwined, a relatively new development in such coverage. And, it turns out that the recent blistering record heatwave in India and Pakistan is but a foretaste of our future.
Those of us who have covered climate change in the last two decades believed that by the time such connections became obvious and noted by mainstream outlets, the world would be so far along in the process of global warming that stability-challenging events such as grid failures would become normal.
That's because of the lag time between when we introduce greenhouse gases into the atmosphere and when we experience the warming caused by them is between 25 and 50 years. This is due to what's called the thermal inertia of the oceans which means more or less that the oceans take time to warm (usually decades). Even if we were to take drastic action now that stopped all further emissions of greenhouse gases, the world would be in for several more decades of rising temperatures. But, of course, we as a global society are instead pursuing business as usual.
