New research from the University of Victoria (UVic) has found that some kelp forests around Vancouver Island were disappearing far earlier than scientists previously thought, highlighting that climate change has been altering our ecosystems long before most people were aware anything was wrong.

“Most research has focused on recent kelp forest losses resulting from well-known marine heatwaves, like the record-breaking ‘Blob’ heatwave that hit our coast a decade ago,” says Brian Timmer, a UVic PhD student, National Geographic Explorer and lead author of the study, recently published in Ecological Applications.

“These recent changes to our kelp forests have been intense. But our research shows that some areas of the BC coast have been warming much faster than the global average, and associated kelp declines began decades ago. We’ve been underestimating the magnitude of ocean-warming impacts for years.” —Chris Neufeld, co-author and senior aquatic ecology at LGL Limited
