Paper that claimed the Sun caused global warming gets retracted

https://arstechnica.com/science/2020/03/...ted/?amp=1

Quote: A paper published last June was catnip for those who are desperate to explain climate change with anything but human-caused greenhouse gas emissions. It was also apparently wrong enough to be retracted this week by the journal that published it, even though its authors objected.

The paper’s headline conclusion was that it described a newly discovered cycle in the motion of the Sun, one that put us 300 years into what would be a thousand-year warming period for the Earth. Nevermind that we’ve been directly measuring the incoming radiation from the Sun and there has been no increase to explain the observed global warming—or that there is no evidence of a 2,000 year temperature cycle in the paleoclimate record.


Those obvious issues didn't stop some people from taking this study as proof that past warming was natural, and only mild and unavoidable warming lies in our future.

Apparently,  Valentina Zharkova has never heard of the Milankovitch cycles; that the
Earth's orbit changes in three cycles of different lengths.  The Earth's orbit slightly
changes its eccentricity over the course of 100,000 years from nearly 0 to 0.07 and
then back again, according to NASA's Earth Observatory.

When the Earth's orbit has a higher eccentricity, the planet's surface receives 20 - 30%
more solar radiation when its at perihelion—the shortest distance between the Earth and
sun each orbit—than when it is at aphelion—the largest distance between the Earth and
sun each orbit.

When the Earth's orbit has a low eccentricity, there is very little difference in the amount
of solar radiation that is received between perihelion and aphelion.
I'm a creationist;   I believe that man created God.

The Earth's orbit has a low eccentricity right now.

From post #84:

The earth’s axis, the precession of the equinoxes, wobbles on a 23,000 year cycle. The earth’s tilt shifts on a 41,000 year cycle. And the earth’s eccentricity, how elliptical its orbit is, oscillates on a 100,000 year cycle. The 100,000 year cycle has the greatest impact on global average temperatures. Presently, the first two cycles are out-of-phase by about 10,000 years and the orbital eccentricity is small, so the length of our interglacial period would normally be extended beyond the typical. The last time the earth was in this configuration 400,000 years ago, the interglacial was 50,000 years long.
