El Niños Strengthened by Climate Change

El Niños are getting stronger due to climate change, according to a new study in Monday's Proceedings of the National Academy of Sciences.


El Niño is a naturally occurring band of warm ocean water found in the eastern and central Pacific that can cause extreme weather events like floods, droughts and severe storms. Researchers found that climate change is making these phenomena originate increasingly far west where the water is warmer, which can cause them to be more extreme. All 11 El Niños that have occurred since 1978 formed in the central-western Pacific, including three "super" El Niños that broke temperature records.

As reported by Newsweek:

El Niño's slow but steady shift away from International Dateline, eastward of the Deadline but generally westward, is important to note because of the warmth of the water in the west, according to study lead author Bin Wang, an atmospheric scientist at the University of Hawaii.
Wang pointed out that there have been three "super" El Niños, in 1982, 1997 and 2015. All three started in the west. During each of those El Niños, the world broke new average temperature records.
Many forecasters predict a total lack of an El Niño or La Niña — the colder atmospheric counterpoint to El Niño, which causes heavy rains in dry atmospheres and drought conditions in wet atmospheres — during the upcoming winter months.
La Niñas were not part of the published study.

The Office of Disease Prevention and Health Promotion and the World Health Organization currently recommend either 150 minutes of moderate intensity exercise (walking, gardening, doing household chores) or 75 minutes of vigorous aerobic exercise (running, cycling, swimming) every week.

But there's little research looking at the benefits, if any, of exercising less than the 75 minute minimum.

For 21 years, Doug Distaso served his country in the United States Air Force.

He commanded joint aviation, maintenance, and support personnel globally and served as a primary legislative affairs lead for two U.S. Special Operations Command leaders.

But after an Air Force plane accident left him with a traumatic brain injury, post-traumatic stress disorder (PTSD), and chronic pain, Distaso was placed on more than a dozen prescription medications by doctors at the U.S. Department of Veterans Affairs (VA).

If you had to choose a diamond for your engagement ring from below or above the ground, which would you pick … and why would you pick it? This is the main question consumers are facing when picking out their diamond engagement ring today. With a dramatic increase in demand for conflict-free lab-grown diamonds, the diamond industry is shifting right before our eyes.

The scourge of plastic waste that washes up on once-pristine beaches and finds its way into the middle of the ocean often starts on land, is dumped in rivers and canals, and gets carried out to sea. At the current rate, marine plastic is predicted to outweigh all the fish in the seas by 2050, according to Silicon Canals.
