Here's How to Avoid Climate Panics

From Townhall Dennis Avery Posted: Aug 07, 2017 10:01 AM Americans have suffered needless climate-related panic for the past 40 years—not realizing that, since 1850, our newspapers have given us a climate scare about every 25 years. And none of them was valid. Fortunately, climate science is now good enough to predict the key abrupt…

The Climate-Grain Production Relationship Quantified

Guest essay by David Archibald There is now consensus that the Sun has now entered a quiet period. The first paper from the solar physics community predicting the current quiet period was Schatten and Tobiska’s 2003 paper “Solar Activity Heading for a Maunder Minimum?”. To date, Solar Cycle 24 has shown similar maximum SSN amplitudes…

Solar Update February 2013

Guest post by David Archibald Solar Cycle 24 has already seen five consecutive colder winters. This is a link to a post about a German meteorologist who has seen the light. Eventually people will work their way back to where all the energy comes from. The amount and type of energy coming from the Sun…

When will it start cooling?

Guest post by David Archibald My papers and those of Jan-Erik Solheim et al predict a significant cooling over Solar Cycle 24 relative to Solar Cycle 23. Solheim’s model predicts that Solar Cycle 24, for the northern hemisphere, will be 0.9º C cooler than Solar Cycle 23. It hasn’t cooled yet and we are three…

Solar Update March 2012

by David Archibald Figure 1: Heliospheric Current Sheet Tilt Angle 1976 – 2012 The heliospheric current sheet tilt angle is currently at 67°. Solar maximum occurs when it reaches 74° – so a little bit further to go.

Archibald: Solar Based Climate Forecast to 2050

Guest post by David Archibald When I started out in climate science in 2005, the climate people ignored the solar physics community. A casual perusal of the literature though indicated that the difference in climate outcome from Dikpati’s (NASA) estimate for Solar Cycle 24 amplitude of 190 and Clilverd’s (British Antarctic Survey) estimate of 42…
