But the record warmth recently in parts of the North Atlantic could have an opposing effect by fueling stronger hurricanes. El Niño tends to reduce hurricane activity by increasing wind shear, or the changes in wind speed and direction that can disrupt storms as they form. This pile-on has also made it trickier for NOAA to forecast the 2023 Atlantic hurricane season, Dr.

That means the current one has emerged amid planetary conditions that could compound its warming effects. But humans have pumped three additional years’ worth of greenhouse gases into the atmosphere since the last El Niño. The intermittent phenomenon influences weather dynamics worldwide and tends to be associated with warmer years globally.

It has manifested in Siberia, which has been roasted by extreme heat, and around Antarctica, where the extent of the surrounding sea ice last month reached a record low for May. In recent weeks, it has manifested in Canada, where many areas are still dealing with huge forest fires that have churned toxic smoke into the United States. That energy is going to manifest in any number of different ways.” “We’re putting heat into the system - through climate change, through the greenhouse effect - and that heat is going to manifest. “The short version is: Expect surprises,” Rick Spinrad, the administrator of the National Oceanic and Atmospheric Administration, said in an interview on Monday. The spike reflects two factors that are shaping what forecasters say could be a multiyear period of exceptional warmth for the planet: humans’ continued emissions of heat-trapping gases and the return, after three years, of the natural climate pattern known as El Niño.īoth factors are also setting the thermodynamic stage for more-severe hot spells, droughts, wildfires and even hurricanes, which acquire their destructive energy from heat in the oceans. Temperatures around the world this month have been at their highest levels in decades for this time of year.
