Once again, marine heat waves are in the news as a catalyst to a major weather event. A large MHW off the Northwest Africa/Southwest Europe coast the past few months shifted westward the past couple weeks and the latent heat loss where the warm SSTA pattern was previously located (central/west Mediterranean Sea) deepened an upper-level storm that caused "apocalyptic" rains from Italy to Bosnia the past few days.

Many thanks to the GRAINCOM 2023 Gathering in Geneva, Switzerland May 15-17 for inviting Climate Impact Company to present on climate change, both projected and real-time. Special thanks to Dr. Olivia Kellner for her presentation on "Global Cereals Crop Production 2030 and Beyond in a Changing Global Climate System" to a group of many hundreds of delegates from all over the world. An essential and vital speech. Thank you to all that attended!

On May 11th, NOAA/NHC determined an intense storm off the Northeast U.S. Coast gained subtropical characteristics and is considered the first event of the 2023 season. The next storm will be identified as AL02 although given the name Arlene if intensification occurs.

Beginning with the 2013-14 Northeast Pacific marine heat wave (MHW) known at the time as the “warm blob” regional very warm (and cool) ocean surface zones have accelerated and are affecting our climate. The most recent analysis identifying where MHW’s are currently located indicates 5 major events that are ongoing.
