Climate science is still very much a work in progress. This is the sad truth of the matter.&lt;p&gt;Trying to figure out whether or not humans are a direct cause of climate change is like trying to figure out if exposure to a certain household product gives you cancer. People get cancer all the time from various sources, and while certain folk can point directly to said chemical being a carcinogen, even if that agreement exists it starts to open up a whole new debate about whether or not there is &lt;i&gt;enough&lt;/i&gt; of a link to matter.&lt;p&gt;From what I can tell, ignoring the single idiots on either side, we&apos;ve got:&lt;p&gt;1. A general consensus that the world is warming;&lt;p&gt;2. A slightly less strong consensus that humans are contributing to this warming;&lt;p&gt;3. A majority (but not a consensus, IMO) extending that to humans being the most direct and primary cause of warming;&lt;p&gt;4. A strong consensus that we should reduce our overall carbon emissions (for obvious reasons), regardless;&lt;p&gt;5. A small but significant &lt;i&gt;scientific&lt;/i&gt; group arguing that we are not the primary cause of warming, even though we may be a contributing factor;&lt;p&gt;6. A large contingent of non-science laymen that feel that because 5 may be a valid opinion, the entire study of climate science is bunk;&lt;p&gt;That&apos;s basically the best I&apos;ve found. There are zealots in every camp above. There are also those that feel that each individual point being right means we should either ignore everything else, be it science or consequence.&lt;p&gt;Given how complex the earth&apos;s climate is, and how little we know about things like the sun, earth&apos;s climate history, and the long term effects of particular chemical compositions in our atmosphere, I feel we won&apos;t progress much past our current stage in enough time to make much a difference overall. IMHO, if we believe that climate change is real, we should be focusing all efforts on dealing with it as best we can.</text><parent_chain><item><author>MichaelGG</author><text>Can anyone recommend a good book (preferably on Kindle) that explains climate change and our actual scientific knowledge?
