Australasia is the hottest it’s ever been in 1000 years, according to a new study showing the climate’s continuous rise since1950.
Led by researchers at the University of Melbourne, scientists used 27 natural climate records to create the first large-scale temperature reconstruction for the region by assessing natural resources like tree rings, corals and ice cores.
The natural or palaeoclimate records were provided by decades of work by more than 30 researchers from Australia, New Zealand and around the world.
The comparisons made with climate model data reveals the warming cannot be explained solely by natural factors, a finding researchers say suggests a strong influence of human-caused climate change.
The study, published in the Journal of Climate, is part of a global collaboration on the reconstruction of the last 2000 years of climate across all regions in the world.
The intention of the study is to reduce uncertainties surrounding future climate change projections.
