The
study published in the journal Nature says that
paleoclimate records in the past five centuries (500 years) indicate that the constant warming in the tropics and Northern Hemisphere began in the 1830s.
In this
study, which was led by Oregan State University, funded by the US National Science Foundation's
Paleoclimate Program and just
published in Science, researchers used «extensive sea and land surface temperature reconstructions» of around 21,000 years ago — in stead of the (late) Holocene temperature record that is mostly used.
But the most critical point to remember, if you are concerned about this for its impact on the validity of AGW theory, is that the fight is over a single
study,
published eight years ago, focused on
paleoclimate.
To better understand these discrepancies, a recent
study published in Geophysical Research Letters investigates the drivers of changes in deep ocean circulation across a range of modern and Last Glacial Maximum (LGM, ~ 21000 years ago) climate simulations from the latest
Paleoclimate Modelling Intercomparison Project (PMIP).
Authors of a recent
study published in Science Advances used
paleoclimate data to examine how rainfall patterns have responded to past climate shifts.
But a recent
study published in Nature uses
paleoclimate records from the 1500s to show that industrial - era warming first became apparent in the Northern Hemisphere in the mid-1800s.
