Scientists from the Oceanographic Institution in Woods Hole (USA) have identified fresh evidence that climate change is associated with human activity. The results of their research were published in the journal Nature Climate Change.

The researchers analyzed data from a variety of observing systems, including satellite records and ocean measurements collected from research vessels and floating craft since 1950.

Climatologists have identified disruptions to natural sea surface temperature (SST) variability. They found two characteristic features: an increase in the amplitude of seasonal changes in the mid-latitudes of the Northern Hemisphere and a clear dipole structure between the 40th and 55th parallels.

These observations are consistent with predictions from climate models that take into account the influence of human activity on the Earth’s climate. Increased greenhouse gas emissions play a key role in changes in sea surface temperatures, with some but distinct influences from aerosol and ozone emissions.
