The intensification of this phenomenon is closely related to the emergence of industrialization.

After conducting a global analysis of historical sea levels, an international team of researchers found that more with rhythm accelerated from the middle 19th centuryA date that coincides with the intensification of the Industrial Age and the early warming of the oceans.

As detailed in their latest research, published Recently in Nature Communications, during their study they analyzed sea level records for the last time 2000 yearsand finding that the first indicators of recent rates of sea level rise date back to 1863.

According to the results obtained, the first signs of this phenomenon were recorded on the Atlantic coast of the United States, and later in Canada and Europe, where the evidence indicates its occurrence between decades. 1930 and 1960.

The study is relevant, considering that sea level rise is an “important indicator of broader climate changes.” By distinguishing when recent rates of sea-level rise exceeded natural variance, the researchers were able to determine the onset of a significant period of climatic disruption and its relationship to human activities.

“We can be sure that the global average sea level is rising between them 1940 and 2000 It was faster than all the previous 60 years in the last “two millennia, hung Jennifer Walker, co-author of the post. He added, “The fact that modern indicators appeared in all our study sites in the middle of the twentieth century shows the significant impact of global sea level rise on our planet during the past century.”

In addition, the researcher indicated that the statistical model used by the team can be applied to other individual sites, which would shed new light on the processes that lead to sea level change at the global and regional level, as well as its environmental and social impact. Archaeology.
