Ken Caldeira

Ken Caldeira is an American atmospheric scientist and aerologist . Since 2005 he has been a Senior Scientist in the Department of Global Ecology at Carnegie Institution and Professor in the Department of Environmental Earth System Sciences at Stanford University . He is the author of over 150 scientific publications.

Professional background

Caldeira received his BA in philosophy from Rutgers College in 1978 ; his MS followed in 1988 at the Department of Applied Science at New York University in the field of atmospheric science . His Ph.D. he received in the same position in 1991.

Ken Caldeira's research interests are the ocean carbon cycle , carbon dioxide in the earth's atmosphere , the physics of oceans and sea ice, the climate system and energy systems. From 2001 to 2004 he was a member of the US Global Carbon Cycle Scientific Steering Group , from 2002 to 2004 a member of the UNESCO International Oceanography Commission CO ₂ Panel of Experts , 2005 coordinating lead author of the Oceans chapter of the Special Report on the Capture and Storage of CO ₂ , 2007 Committee Member of the report of the Royal Society for the acidification of the oceans and from 2008 to 2012 an advisory member of the EPOCA European Project on Ocean acidification. Since 2009 he has been a member of the steering committee of the Global Carbon Project . In 2009 he was a committee member of the Geoengineering Report prepared for the Royal Society . That same year he served on the America's Climate Choices committee of the National Academy of Sciences .

In order to counter climate change effectively, Ken Caldeira and his colleagues James E. Hansen , Kerry Emanuel and Tom Wigley asked in 2013 in an open letter to promote safer ways for the further use of nuclear energy as a CO _2- saving energy source . A “return to nuclear power ” is necessary, since resistance to nuclear power plants would endanger the fight against climate change. The scientists appealed to politicians and environmental organizations around the world to advocate the development of safe nuclear power plants. In their letter, the four of them are certain that "... there is no realistic way to stabilize the climate that does without a substantial proportion of nuclear energy". However, the risks of nuclear energy are "orders of magnitude smaller" than the dangers posed by the use of fossil fuels . In the debate about future energy policy, facts should decide, not emotions, they said.

In 2016, Caldeira and some colleagues published a peer review among 77 world-leading atmospheric scientists and geochemists on chemtrails , that is, supposedly unusually persistent contrails in the sky that would indicate a large-scale secret spraying program in the atmosphere. 98.7% of the surveyed scientists stated that their research did not find any evidence of such manipulation of the atmosphere. The contrails visible in the sky could easily be explained using conventional chemistry and physics.

Honors

In 2004 he was honored with the Edward Teller Fellowship by the Lawrence Livermore National Laboratory . In 2010 he became a Fellow of the American Geophysical Union .
