&nbsp;除了燃烧化石燃料所引起的温室气体排放，科学家还说明了其他因素也可以影响未来二氧化碳的水平。另一方面，在更温暖的环境中，植物可能生长，吸收更多二氧化碳。但是，如果土壤变得更温暖，那么枯死的植物和叶片就可能更容易在冬天腐烂，释放出更多的二氧化碳。</p><p class="MsoNormal" style="MARGIN: 0cm 0cm 0pt;"><br/>&nbsp;&nbsp;&nbsp; 海洋升温可能意味着海洋吸收的二氧化碳更少，一部分原因是更温暖的海水层的浮力更大，阻止了暖水与更深层的海水融合。<font size="+0"></font></p></font></span><font size="+0"></font></font></td></tr></tbody></table></p>

少擔心啦。。。。。。到時咱们都早已。。。。。。。。。。。。。。。

<p>咁都仲叫少擔心啊？？</p><p>個時真喺一鍋熟咯······</p>

還是擔心現在好了。。。。。。。。。。

<p>如果有一日我地都被呢D高温包围,令到我地变了后天的一样~~~~</p><p>我地会点啊.?</p>

我是宽佬懒理。。。。。。。。。還是看眼前的要紧

宜家D天气已经热咗好多咯
