What you need to know, currently.

Today's climate modeling can help predict ocean heat waves, months in advance, according to new research from National Oceanic and Atmospheric Administration (NOAA) scientists.

Scientists say that the only sure way to prevent future damaging ocean heat waves is to reduce our reliance on fossil fuels. However, this modeling can help communities and scientists take preventative measures to protect ocean wildlife and reduce the stress placed on ecosystems.

“Today’s seasonal climate models could help to identify moments when taking extra care to reduce other threats could avert a devastating blow from which a fishery, a reef, or a whale population might not recover,” wrote NOAA.

Marine and ocean heat waves can be extremely disruptive to ecosystems. Coral reefs have been one of the most prominent cases of ecosystems affected by heat waves in recent years. According to NOAA, between 2014 and 2017, about 75 percent of global reefs experienced heat stress that triggered bleaching.
