It looks like the reports of the demise of the global warming pause are greatly exaggerated. A study just published in the journal Nature Communications reveals that volcanic eruptions as a potential reason for the global warming hiatus. According to Tech Times, researchers at the Max Planck Institute at the University of Lund, Sweden partnered with scientists at the Karlsruhe Institute of Technology and the Leibniz Institute for Tropospheric Research.
The team gathered atmospheric information in an effort to explain the global warming pause that has taken place over the last ten years. The results showed that climate models underestimated the cooling effect of volcanic eruptions especially the models used by the Intergovernmental Panel on Climate Change (IPCC) in its most recent report. The manuscript did state that the cooling effect is short-lived since the Earth’s temperature levels are rising due to greenhouse gases. As far as what and how information for the study was used, Tech Times states:
Data for the study was gathered through observations from the Cloud-Aerosol Lidar and Pathfinder Satellite Observation mission and in situ measurements and sampling made by IAGOS-CARIBIC observatory. Collected particles were analyzed with an ion beam accelerator at the University of Lund, Sweden to determine concentration levels.
“The ratio of particulate sulfur to ozone … clearly demonstrates the strong influence from volcanism on the tropopause region,” explained Sandra Andersson and Bengt Martinsson, lead authors for the study.
The tropopause is a transition layer between the troposphere and the stratosphere. An increase in volcanic aerosol particles in the region coincided with times that average surface temperature did not increase.
In particular, observations on volcanic aerosol particles showed levels were more prominent from 2005 to 2012. During this period, the Kasatochi erupted in the United States in 2008, the Sarychev in Russia in 2009 and the Nabro in Eritrea in 2011. Each of these eruptions deposited over one megaton of sulfur dioxide in the atmosphere.
The study’s researchers also say the amount of volcanic sulfuric acid and the height volcanos eject it is are major components in concluding if volcanic eruption contributes to the global warming hiatus. In short, while volcanic eruptions are destructive, they curtail global warming by injecting particulates into the atmosphere.
The data sets that showed the global warming pause were changed in an attempt to wipe out the global warming pause just like what has been attempted by some scientists to erase the Medieval Warming Period and the Little Ice Age. Now a study is out that not only affirms the existence of the global warming pause but also declares the climate models used by the IPCC miscalculated how volcanos contributed to it. It’s abundantly clear that the global warming pause was an inconvenient truth for scientists who subscribe to the so-called consensus on man-made climate change.
