<p>Dr. Horse,</p>
<p>As you can see in the graph below, temperatures have been rising for about 150 years.</p>

<p>Now, solar cycles last only 11 years. There is no way you can blame a cycle that lasts 11 years on something that has been happening for 150.</p>
<p>Nonetheless, studies have been done to research the effective of radiative forcing on the climate. As expected, all have concluded that is has little to no effect.</p>
