New study casts fresh doubt over global warming ‘pause’
Results of a new analysis of climate data has supported the controversial study that suggested there has been no slowdown in global warming over the first fifteen years of this century.
According to the new analysis report, climate scientists involved in the previous study underestimated ocean temperatures over the last couple of decades, which led them to misunderstand that global warming slowed down between 1998 and 2014.
Lead author Zeke Hausfather said, “Only a small fraction of the ocean measurement data is being used by climate monitoring groups, and they are trying to smush together data from different instruments, which leads to a lot of judgement calls about how you weight one versus the other, and how you adjust for the transition from one to another.”
The notion of a pause in global warming had gained support in recent years form scientists around the globe. In 2013, even the Intergovernmental Panel on Climate Change (IPCC) reported that the global surface temperature had shown a much smaller rising linear trend over the past fifteen years than over the past 30-60 years.
But with the revised climate data, Hausfather and colleagues found that the preciously detected pause in temperature increases in those years disappeared.
The alarming findings of the new research were reported in the most recent edition of the journal Science Advances.
