Scientists have been carefully observing how the Pacific is changing from #ElNiño to #LaNiña conditions by late summer.
But as it happens, something similar might be cooking in the Atlantic!

One might think that a temperature difference of ±0.5 degrees Celsius (± 0.9 degrees Fahrenheit) in the tropical Atlantic does not seem like a big deal, but this difference can have a huge impact on rainfall over the surrounding continents. Reduced rainfall over the Sahel region, increased rainfall over the Gulf of Guinea, and seasonal shifts of the rainy season in northeastern South America have all been attributed to Atlantic Niño events.
Plus, Atlantic Niños have been shown to increase the likelihood of powerful hurricanes developing near the Cape Verde islands. NOAA’s seasonal forecast of above-normal 2024 hurricane activity is based on expected La Niña conditions in the equatorial Pacific and warm ocean temperatures in the tropical North Atlantic. It will be interesting to monitor whether this Atlantic Niña fully develops, and if so, whether it has a dampening effect on hurricane activity as the season progresses.
We’ll be keeping an eye on this event in coming weeks, and will have a follow-up post later this month letting you know whether an Atlantic Niña fully developed. We’ll also go over some of the hypotheses scientists have for what triggers these events and how their frequency might be affected over the coming century

If you're worried about ticks, put up an owl box.
The animal driving most Lyme disease in the eastern US is the white-footed mouse. Ticks that feed on them are far more likely to come away infected than ticks that feed on other animals. The bigger the local mouse population, the worse the next year's tick year.
A single barred owl pair raising chicks can take hundreds of rodents in a breeding season. Owls also don't carry Lyme. The bacterium can't survive their digestive tract, so an owl that eats an infected mouse is a dead end for the disease.
Researchers at the Cary Institute, the leading lab on Lyme ecology, have been explicit about this: "Landscapes that support predators have reduced Lyme disease risk."
One owl box on its own isn't going to fix a tick year. But a yard with owls, foxes, bobcats, and weasels in it has fewer mice, and a yard with fewer mice has fewer infected ticks.
If you have woods or fields nearby, a properly sized barn owl or screech owl box (different species, different ...
