I skimmed the recent IPCC report and keep up with science news, mostly via Ars Technica. A good summary is at Wikipedia:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;IPCC_Fifth_Assessment_Report" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;IPCC_Fifth_Assessment_Report</a><p>&quot;&quot;&quot;The global surface temperature increase by the end of the 21st century is likely to exceed 1.5 °C relative to the 1850 to 1900 period for most scenarios, and is likely to exceed 2.0 °C for many scenarios&quot;&quot;&quot;<p>&gt; I ask because as far as I can tell we were told 20 years ago that it would be too late 10 years in the future (10 years ago for us) based on models that have clearly not panned out.<p>Yes, it is unfortunate that science isn&#x27;t perfect, but it&#x27;s the best we have, and computer projections have only made it more reliable in recent years than it was in the 80s and 90s. I understand that changing the base of our entire economic system isn&#x27;t easy, but it&#x27;s becoming blindingly clear that it needs to happen to halt more disastrous changes. Deniers like Smith are preventing positive action on climate change from occurring, and side-shows like the NOAA investigation are a waste of both critical time and money.<p>If we had taken action twenty years ago, perhaps we wouldn&#x27;t be having this conversation at all.
