					<description><![CDATA[Greenhouse gases go up and down in three ways. First, there is the annual up and down cycle that happens because there is more land in the Northern Hemisphere. I won&#8217;t explain that to you now because I know you can figure out why that happens. Second, there is natural variation up and down aside &#8230; <a href="https://gregladen.com/blog/2017/08/16/spike-in-greenhouse-gasses/" class="more-link">Continue reading <span class="screen-reader-text">Spike in Greenhouse Gasses</span> <span class="meta-nav">&#8594;</span></a>]]></description>

					<description><![CDATA[The Keeling Curve is the measurement of CO2 in the Earth&#8217;s atmosphere. As we burn fossil fuel or damage &#8220;Carbon sinks&#8221; we increase that number. The Keeling curve is at the root of much of the science of global warming. It goes up over time because of the release of fossil Carbon, and it wiggles &#8230; <a href="https://gregladen.com/blog/2014/08/26/the-keeling-curve/" class="more-link">Continue reading <span class="screen-reader-text">The Keeling Curve</span> <span class="meta-nav">&#8594;</span></a>]]></description>
