<jats:title>The future in the past</jats:title> <jats:p> A major cause of uncertainties in climate projections is our imprecise knowledge of how much warming should occur as a result of a given increase in the amount of carbon dioxide in the atmosphere. Paleoclimate records have the potential to help us sharpen that understanding because they record such a wide variety of environmental conditions. Tierney <jats:italic>et al.</jats:italic> review the recent advances in data collection, statistics, and modeling that might help us better understand how rising levels of atmospheric carbon dioxide will affect future climate. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" related-article-type="in-this-issue" xlink:href="10.1126/science.aay3701">eaay3701</jats:related-article> </jats:p>

<jats:p> Racism, climate denial, and coronavirus disease 2019 (COVID-19) are major crises standing in the way of a prosperous future for the United States, and resolution of all three could be enabled by science that is persistently ignored. In Ernest Hemingway's novel <jats:italic>The Sun Also Rises</jats:italic> , a character named Mike is asked how he went bankrupt. “Two ways,” he answers. “Gradually, then suddenly.” The resistance of U.S. policy to science has followed a similar path: It gradually built up over 40 years, beginning with the election of Ronald Reagan, but suddenly reached a tipping point in the chaos of 2020. Will the path to resolution also be gradual and then sudden, and if so, at what cost? </jats:p>
