Recent research highlights a clear human impact on sea surface temperatures , revealing significant changes in seasonal temperature cycles linked to human activities. This study, utilizing various observational data sets and climate models, identifies greenhouse gases as the primary drivers of these changes, which have profound implications for marine ecosystems, the ocean’s role as a carbon sink, and global climate patterns.
New oceanic research provides clear evidence of a human “fingerprint” on climate change and shows that specific signals from human activities have altered the seasonal cycle amplitude of sea surface temperatures .increases,” according to co-author Benjamin Santer, an adjunct scientist and distinguished scholar in the Physical Oceanography Department at Woods Hole Oceanographic Institute .
“This research rebuts claims that recent temperature changes are natural, whether due to the Sun or due to internal cycles in the climate system. A natural explanation is virtually impossible in terms of what we are looking at here: changes in the seasonal temperatures of the ocean,” stated Santer. “This research further rules out the claim that we don’t need to treat climate change seriously because it is natural.
“Ocean temperatures are literally off the charts. A lot of people want to know what is happening,” said Santer. “A big part of the answer is that human activities have gradually warmed the world’s oceans. The scientific community has been focused on changes in the ocean’s annual average temperature. This paper shows that it’s also critically important to perform fingerprinting with seasonal changes,” said Santer.
