Last month I explored Greenland’s and West Antarctica’s accelerating ice loss. Both are approaching tipping points beyond which continuing ice loss becomes irreversible. Yet, these glaciers are so massive that it’s hard to imagine them withering away. For that task…
Climate scientists lose sleep over tipping points, temperature thresholds when crossed initiate self-sustaining, irreversible, and massively-destructive changes in natural systems, such as glaciers and forests. Countless living things will face untimely and unnatural deaths if these systems collapse. New…
Ameren and MISO are playing politics with state regulations, slow walking Illinois into an electricity shortage Past columns revealed Exelon crippling the Illinois Renewable Portfolio Standard and thus contributing to Illinois’ electricity shortage. Additionally, Exelon supports its grid operator’s…
Illinois once exported 40% of its electricity generation. Now, we must import electricity. Between 2007 and 2020, 44 Illinois coal plants closed (EIA) thus eliminating a sizeable fraction of our generation capacity. Another 12 coal plants may close by 2023.…
The ultimate just-in-time commodity, supply and demand for electricity must be immediately and precisely balanced. If a supply deficit can’t be closed rapidly, grid operators order round-robin shutoffs across all customers, i.e. “rolling blackouts” lasting hours to days depending on…
My last column finds the Illinois Emergency Management Agency whitewashing heatwave risk by aggregating a misleading measure into just one score for a county. Thus, Cook County’s 136 diverse municipalities, and strikingly diverse 1,332 census tracts, are all labeled as…
Deadly heat gets no respect. Natural hazards that count — tornadoes, floods, etc. — are property-destroying traumas. Homeowners, public infrastructure, and insurance companies all take big hits. The Great Flood of 1993, for example, destroyed 24,000 Illinois homes and 884,000…
A climate crisis conundrum involves heatwaves, air conditioners, and blackouts. Air conditioning saves lives during heatwaves, but soaring AC demand can crash the grid and claim lives. Today, the top 20% of peak electricity demand involves the hottest 200 hours…
Murphy’s Law, “If anything can go wrong, it will,” merits climate crisis amplification: If two things can go wrong simultaneously, they will. And they have via electricity blackouts due to extreme weather. Examples: California in August 2020, and Texas in…
Yes, and fast — but a reprise first. California’s “duck curve” in January’s column exposes the misfit between nukes and renewables. The duck curve shows how increasing solar output would replace midday fossil generation until solar output bumped into (in…
