Sub Statement: An enormous marine heatwave off the US west coast is ringing alarm bells among ocean and atmospheric scientists. An triangle shaped unusually warm water stretches thousands of miles from the California coastline and Mexico to Hawaii to the British Columbia. New projections by the National Oceanic and Atmospheric Administration (Noaa) show it is now expected to expand and strengthen due in the months to come. The heated waters is already reshaping marine biology and ecosystem. A few weeks ago, the first-ever evidence of a great white shark was found in British Columbia waters. Subtropical species – from plankton to pelicans to great whites – are shifting their range further north and closer to shore in search of cooler water and more food. Millions of seabirds and marine deaths were witnessed over the years and the this year's incoming heat wave could propel those numbers.
