I think the drawback to your argument is that you&#x27;re not considering all scenarios. One &quot;worst-case&quot; I can think of is that we charge ahead with measures to combat climate change, harming big parts of the economy in the process, and wind up with the famine, drought, and flooding anyway because we didn&#x27;t charge ahead with the <i>right</i> measures.<p>It&#x27;s <i>extremely</i> important to determine whether the global warming is caused by us or not, and whether or not we can alter global warming whether we caused it or not. If it&#x27;s mostly natural (and we know the earth has gone through much warmer periods long before we showed up) then the measures we need to take involve protecting our coastal cities and our food and energy supplies. If it&#x27;s mostly caused by us, then we need to stop doing what&#x27;s causing it, and probably need to protect our coastal cities and food and energy supplies anyway.
