15 Facts About Nir Shaviv
1. 2.
Nir Shaviv is known for his solar and cosmic-ray hypothesis of climate change which disagrees with the scientific consensus on human-caused climate change.
3.
In 2002, Shaviv hypothesised that passages through the Milky Way's spiral arms appear to have been the cause behind the major ice-ages over the past billion years.
4.
Nir Shaviv's best known contribution to the field of astrophysics was to demonstrate that the Eddington luminosity is not a strict limit, namely, that astrophysical objects can be brighter than the Eddington luminosity without blowing themselves apart.
5.
Nir Shaviv started taking courses at the Israel Institute of Technology in Haifa at age 13.
6.
In 1999, Nir Shaviv has shown that inhomogeneities in stellar atmospheres reduce the effective opacity and thus increase the Eddington luminosity.
7.
Nir Shaviv later showed that atmospheres are inherently unstable as the Eddington luminosity is approached, that these atmospheres will develop continuum driven winds that explain the appearance of eta-Carinae and classical nova eruptions.
8.
Nir Shaviv has been one of the proponents of a cosmic ray climate link.
9.
Nir Shaviv has shown that the cosmic ray climate link explains part the faint young Sun paradox, since the slowly decreasing solar wind will give rise to a cooling effect that compensates the solar irradiance increase.
10.
In 2008, Nir Shaviv used the oceans as a giant calorimeter to quantify the solar radiative forcing.
11.
Nir Shaviv argues that Lockwood and Froehlich's analysis is flawed for a number of reasons.
12.
Secondly, Nir Shaviv argues that short term variations in radiative forcing are damped by the oceans, leading to a lag between changes in solar output and the effect on global temperatures.
13.
Nir Shaviv disagrees with the scientific consensus on human-caused climate change.
14.
Nir Shaviv was interviewed for The Great Global Warming Swindle documentary.
15.
Nir Shaviv has been a speaker for the Heartland Institute.
