485-myr地球温度研究显示,人类引起的气候变化造成前所未有的变暖。 485-myr Earth temperature study reveals human-induced climate change causes unprecedented warming.

*Science* 发表的一项研究报告表明,过去4.85亿年中,地球温度大幅波动,主要受大气二氧化碳水平的影响。 A study published in *Science* reveals that Earth's temperature has fluctuated significantly over the past 485 million years, primarily influenced by atmospheric carbon dioxide levels. 它确认,目前的气温比这段时期的大部分气温更温和,并强调人类引起的气候变化正在以前所未有的速度造成气候变暖,威胁全球生态系统。 It confirms that current temperatures are cooler than much of this period and underscores that human-induced climate change is causing warming at an unprecedented rate, threatening global ecosystems. 这一研究增进了对历史气候变异及其对现代挑战的影响的了解。 This research enhances understanding of historical climate variations and their implications for modern challenges.
