In the first video: Alarmist sea level rise scenarios looking more unlikely…some Antarctic regions will see cooling…
World Climate News presents the latest scientific results, featuring commentary on and analysis of peer-reviewed articles from well-known journals.
Even the IPCC disregards alarmist sea level projections
Concerning sea level rise, Potsdam climate researcher Stefan Rahmstorf and other far-out alarmists have warned global sea levels could rise up to “one meter ninety” before the end of this century. Yet, Intergovernmental Panel on Climate Change (IPCC) takes a different view. In its 5th State of the Climate Report of 2013, for example, it projects a sea level rise of just 53 centimeters for a scenario where CO2 emissions peak around 2040.
Brakes on sea level rise as some Antarctic regions expected to get colder!
The 2013 IPCC projection has now been backed up by René van Westen and Henk Dijkstra from the University of Utrecht. Their published results of a sea-level computer simulation in the journal “Science Advances” showed that the ocean around Antarctica is hardly expected to warm up and that regions are even expected to get colder by the end of the century.
Thus, according to the new calculations, the ice melt caused on the coasts of Antarctica is only a third of what earlier, lower-resolution simulations suggested.
Antarctic ice volume to reduce sea level rise 25%
The new model also expects more snowfall in Antarctica and the Antarctic ice mass is even expected to remain unchanged and stable overall this century. In this respect, Antarctica will probably make no contribution at all to global sea-level rise by 2100. This reduces the rise in sea level to be expected in this century by 25%.
While the old model assumed a sea-level rise of about 42 cm, it is now only 33 cm, i.e. 9 cm less. A value that is far removed from the dramatic scenarios of the Potsdam Institute for Climate Impact Research.
No data supporting link between warming and tornadoes
When it comes to tornado activity, December 2021 saw a series of violent tornadoes in the southeastern USA. More than 85 people died. As expected, the usual suspects pointed the finger at man-made climate change, World Climate News reports in the video.
However, Andreas Friedrich of the German Weather Service, DWD, reminded in mid-December 2021 that there is currently no evidence that the series of tornadoes is related to climate change. This is supported by Chris Martz, who plotted the tornado statistics for the USA using data from the National Centers for Environmental Information (NCEI) for the last 65 years.
The result? No discernible trend.
How will tornadoes develop in the future? According to Matthew Woods of the University of Illinois at Urbana-Champaign, tornadoes could become rarer but more violent. The bottom line is that the future remains uncertain.
