New Study Finds Oceans Retain 60 Percent More Heat Than Previously Thought


WASHINGTON, D.C. -- Today, a new study released by scientists at Princeton University found that the world’s oceans have retained 60 percent more heat than previously thought, indicating that the climate crisis may be even more dire than first realized. Warmer oceans correlate to stronger superstorms and exacerbate climate effects like coral bleaching.

Earlier this month, the Intergovernmental Panel on Climate Change (IPCC) released a report found that catastrophic effects of the climate crisis could occur by 2040 as the world surpasses the vital threshold of 1.5 degrees Celsius temperature increase.

In response, Sierra Club Executive Director Michael Brune released the following statement:

"The world’s oceans are the canaries in the coal mine when it comes to the climate crisis. The writing has been on the wall for years, but today’s report confirms that we have even less time to move beyond dirty fossil fuels like coal, oil, and fracked gas to an economy powered by 100 percent clean, renewable energy. This global crisis demands nothing less than swift and meaningful action by every world leader to ensure a safe and healthy future for all. The Trump Administration’s continued ignorance and lack of action is wholly unacceptable, and together with our allies across the country, we will work toward a brighter, healthier and safer future for all.”
