Indeed, we argue that 20–30 years periodicities in Sea Surface Temperatures (SSTs) as part of the the Atlantic Multi-decadal Oscillation (AMO) directly influence heat transfers to adjacent lands. Winter atmospheric conditions associated with the North Atlantic Oscillation (NAO) might also impact EC’s taiga forests, albeit indirectly, through its effect on SSTs and sea ice conditions in surrounding seas. Our work emphasizes that taiga forests would benefit from the combined effects of a warmer atmosphere and stronger ocean-to-land heat transfers, whereas a weakening of these transfers could cancel out, for decades or longer, the positive effects of climate change on Eastern Canada’s largest ecosystem.</span></div><div class=""><div style="orphans: 2; widows: 2;" class=""><font color="#222222" class=""><span style="letter-spacing: 0.17000000178813934px; background-color: rgb(255, 255, 255);" class=""><br class=""></span></font></div><div style="orphans: 2; widows: 2;" class=""><font color="#222222" class=""><span style="letter-spacing: 0.17000000178813934px; background-color: rgb(255, 255, 255);" class=""><br class=""></span></font></div><div style="orphans: 2; widows: 2;" class=""><font color="#222222" class=""><span style="letter-spacing: 0.17000000178813934px; background-color: rgb(255, 255, 255);" class=""><br class=""></span></font></div><div style="orphans: 2; widows: 2;" class=""><font color="#222222" class=""><span style="letter-spacing: 0.17000000178813934px; background-color: rgb(255, 255, 255);" class=""><br class=""></span></font></div><div style="orphans: 2; widows: 2;" class=""><font color="#222222" class=""><span style="letter-spacing: 0.17000000178813934px; background-color: rgb(255, 255, 255);" class=""><br class=""></span></font></div><div class=""><div class="">******************************************************************************************</div></div></div><div class=""><div style="color: rgb(0, 0, 0); font-family: Verdana; font-size: 14px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px;"><br class="">"Our results indicate that future reductions in Arctic sea ice cover could significantly reduce available water in the American west...."<br class=""><br class=""> Jacob O.
