Novel and disappearing climates in the global surface ocean from 1800 to 2100

Abstract

Marine ecosystems are experiencing unprecedented warming and acidification caused by anthropogenic carbon dioxide. For the global sea surface, we quantified the degree that present climates are disappearing and novel climates (without recent analogs) are emerging, spanning from 1800 through different emission scenarios to 2100. We quantified the sea surface environment based on model estimates of carbonate chemistry and temperature. Between 1800 and 2000, no gridpoints on the ocean surface were estimated to have experienced an extreme degree of global disappearance or novelty. In other words, the majority of environmental shifts since 1800 were not novel,

Carbon Dioxide, Which Drives Climate Change, Reaches Highest Level In 4 Million Years

This 2019 photo provided by NOAA shows the Mauna Loa Atmospheric Baseline Observatory in Hawaii. Measurements taken at the station in May 2021 revealed the highest monthly average of atmospheric carbon dioxide in human history.

Innovation Outlook: Ocean Energy Technologies

Innovation Outlook: Ocean Energy Technologies

Oceans contain vast renewable energy potential – theoretically equivalent to more than double the world’s current electricity demand. Nascent ocean energy technologies could cut carbon dioxide (CO2) emissions from power generation and help to ensure a sustainable, climate-safe energy future.

Alongside other offshore renewable energy technologies, ocean energy – including wave, tidal, salinity gradient and ocean thermal energy conversion technologies – forms a crucial component in the world’s emerging blue economy.

This outlook from the International Renewable Energy Agency (IRENA)
