I find that substantial numbers of Republicans endorse statements contemplating violations of key democratic norms, including respect for the law and for the outcomes of elections and eschewing the use of force in pursuit of political ends. The strongest predictor by far of these antidemocratic attitudes is ethnic antagonism—especially concerns about the political power and claims on government resources of immigrants, African-Americans, and Latinos. The strong tendency of ethnocentric Republicans to countenance violence and lawlessness, even prospectively and hypothetically, underlines the significance of ethnic conflict in contemporary US politics.</span></p><p style="margin: 0px 0px 12.4px; font-stretch: normal; line-height: normal; color: rgb(17, 17, 17); -webkit-text-stroke-width: initial; -webkit-text-stroke-color: rgb(17, 17, 17);" class=""><span style="font-kerning: none; background-color: #ffffff" class=""><b class="">Abstract</b></span></p><p style="margin: 0px 0px 15px; font-stretch: normal; line-height: normal; color: rgb(51, 51, 51); -webkit-text-stroke-width: initial; -webkit-text-stroke-color: rgb(51, 51, 51); background-color: rgb(255, 255, 255);" class=""><span style="font-kerning: none" class="">Most Republicans in a January 2020 survey agreed that “the traditional American way of life is disappearing so fast that we may have to use force to save it.” More than 40% agreed that “a time will come when patriotic Americans have to take the law into their own hands.” (In both cases, most of the rest said they were unsure; only one in four or five disagreed.) I use 127 survey items to measure six potential bases of these and other antidemocratic sentiments: partisan affect, enthusiasm for President Trump, political cynicism, economic conservatism, cultural conservatism, and ethnic antagonism. The strongest predictor by far, for the Republican rank-and-file as a whole and for a variety of subgroups defined by education, locale, sex, and political attitudes, is ethnic antagonism—especially concerns about the political power and claims on government resources of immigrants, African-Americans, and Latinos. The corrosive impact of ethnic antagonism on Republicans’ commitment to democracy underlines the significance of ethnic conflict in contemporary US politics.</span></p><div class="">=====================================</div>

Based on observations combined with models, the authors claim that from 1990 to 2013, the energy of the currents increased by some 15% per decade. No sustained, direct measurements of currents around the world are available, so the team turned to reanalyses, which combine observations of the ocean and atmosphere with computer models to fill in the gaps and produce a global picture. Five different models showed a distinct rise starting around 1990. Independent data from the Argo array, a fleet of nearly 4000 robotic floats deployed around the world, showed a similar rise from 2005 to 2010.</span><span style="font-stretch: normal; line-height: normal; font-family: Arial; -webkit-font-kerning: none;" class=""> <b class="">The increase is driven by higher winds over the oceans, </b></span><span style="font-kerning: none" class="">the authors say. </span><span style="font-stretch: normal; line-height: normal; font-family: Arial; -webkit-font-kerning: none;" class=""><b class="">If the acceleration is verified and continues, it could affect jet streams, weather patterns, and the amount of heat stored in the ocean's depths</b></span></div><div style="margin: 0px; font-stretch: normal; line-height: normal; color: rgb(51, 51, 51); background-color: rgb(255, 255, 255);" class=""><span style="font-stretch: normal; line-height: normal; font-family: Arial; -webkit-font-kerning: none;" class=""><b class=""><br class=""></b></span></div><div style="margin: 0px; font-stretch: normal; line-height: normal; color: rgb(51, 51, 51); background-color: rgb(255, 255, 255);" class=""><span style="font-stretch: normal; line-height: normal; font-family: Arial; -webkit-font-kerning: none;" class=""><b class="">===================================================================</b></span></div><div style="margin: 0px; font-stretch: normal; line-height: normal; color: rgb(32, 33, 36); min-height: 17px;" class=""><span style="font-kerning: none" class=""></span><div style="margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue"; color: rgb(51, 51, 51); background-color: rgb(255, 255, 255);" class=""><span style="font-kerning: none" class="">PNAS May 26, 2020 117 (21) 11350-11355; first published May 4, 2020</span></div><div style="margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue"; color: rgb(0, 90, 150); background-color: rgb(255, 255, 255);" class=""><span style="font-kerning: none; color: #333333" class=""> <a href="https://doi.org/10.1073/pnas.1910114117" class=""><span style="font-kerning: none; color: #005a96" class="">https://doi.org/10.1073/pnas.1910114117</span></a></span></div><div style="margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue"; color: rgb(0, 90, 150); background-color: rgb(255, 255, 255); min-height: 16px;" class=""><span style="font-kerning: none" class=""></span><br class=""></div><div style="margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue"; color: rgb(0, 0, 0);" class=""><span style="font-kerning: none; background-color: #ffffff" class=""><b class="">Future of the human climate niche</b></span></div><div style="margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue"; color: rgb(0, 90, 150); background-color: rgb(255, 255, 255);" class=""><span style="font-kerning: none" class=""><a href="http://orcid.org/0000-0002-1841-9032" class=""> </a></span></div><div style="margin: 0px; font-stretch: normal; line-height: normal; font-family: "Helvetica Neue"; color: rgb(51, 51, 51);" class=""><span style="font-kerning: none; background-color: #ffffff" class="">Chi Xu, Timothy A.
