El Niño events are measured by looking at temperature levels in a vast rectangular zone in the central Pacific. In a moderate El Niño, temperatures might climb, say, 1 degree Celsius, or 1.8 degrees Fahrenheit, above a longer-term average. But in the biggest El Niños of the past 50 years — the ones that started in 1982, 1997, and 2015 — temperatures have soared 2 degrees Celsius or more beyond the norm. Each of those events levied a global economic toll.
This year, many forecasts say the temperature could increase by an unprecedented 3 degrees Celsius. Even the 1877 El Niño, by the best estimates, didn’t have that magnitude.
“A number of the models now show a real chance for a record-setting El Niño event,” said Zeke Hausfather, a research scientist at Berkeley Earth. “It is still too early to know for sure.”
El Niño events typically peak in strength late in a calendar year, and then cause warmer global temperatures on land in the months that follow. As a result, many scientists predict that 2027 will be the warmest year on record.




HFCs include popular refrigerants such as R-134a, which was introduced as a less bad alternative to CFCs such as R-12, but which has also been superseded by even less bad alternatives such as R-1234yf. This has been good for American manufacturing, as it stimulates turnover in durable goods (expensive) rather than just recharging leaking systems with additional refrigerant (cheap):
So this move is a combination of environmental middle finger and drag on US GDP, hurting sales of domestic manufacturing.
Allowing Kroger to further limp along their leaking refrigerators will be somewhat meaningful to their bottom line, by delaying capital expenses that they’ve been expecting to incur (and presumably budgeting for). But it’s not going to be meaningful to retail grocery prices.
Consumers owning old vehicles with bad A/C might benefit from being able to buy more R-134a for a bit longer, but that’s not what’s motivating it, since Trump doesn’t care about the little guy.
