科学家们开始描绘一幅更清晰的画面，如果目前的变暖趋势继续下去，将有多少人会受到气候变化的影响。

根据发表在《自然》杂志上的一项研究，世界上大约85%的人口已经生活在受到人类引起的气候变化影响的地区自然星期二。

柏林的研究人员汇编了10多万项影响研究的数据，分析了人类引起的气候变化的可检测环境信号，发现气候变化如何影响社区的证据正在不断增加。

柏林墨卡托全球公域和气候变化研究所的研究员、该研究的作者之一马克斯·卡拉汉(Max Callaghan)告诉美国广播公司新闻，“几乎在我们有足够数据的每一项研究中，我们都可以看到，(世界)变得越来越热，而且以一种一致的方式变得越来越热。

卡拉汉说，这项研究还研究了气温上升如何改变降水模式，如何影响作物产量和当地生态系统，并发现全球80%的土地面积正在发生温度和降水的人为变化，全球约85%的人口居住在这些土地上。

他补充说，最不发达国家将感受到最强烈的影响，但人们对这些影响到底是什么样的知之甚少。他将缺乏数据描述为需要填补的“归因缺口”。

“在高收入国家，几乎所有这些人都生活在一个有大量证据表明这种变暖趋势如何影响其他系统的地区，”他说。“但是在低收入国家...几乎没有证据表明这种变暖趋势是如何影响其他事情的。”

卡拉汉说，这项新研究让科学家们几乎可以肯定地认为，全球气温上升是因为人类对地球的影响。尽管之前的研究通常集中在2050年或2100年可能出现的情况，但很明显，气候变化“已经在发生了”。

研究人员表示，各国将需要在不久的将来大幅减少温室气体排放，以缓解即将到来的灾难的极端性。

卡拉汉说:“只要我们继续燃烧化石燃料，情况就会变得更糟。"在我们达到净零之前，情况将继续恶化。"

Human-induced climate change may affect 85% of the global population, researchers say

Scientists are beginning to paint a clearer picture on just how many people will be affected by climate change if current warming trends continue.

About 85% of the world's population already lives in areas experiencing the affects of human-induced climate change, according to a study published inNatureon Tuesday.

Researchers in Berlin compiled data from more than 100,000 impact studies analyzing detectable environmental signals of human-induced climate change, finding that the evidence for how climate change is impacting communities is continuing to grow.

"In almost every study where we have enough data, we can see, [the world] is getting hotter, and it's getting hotter in a way that is consistent," Max Callaghan, a researcher at the Mercator Research Institute on Global Commons and Climate Change in Berlin and one of the authors of the study, told ABC News.

The research also looked at how rising temperatures change precipitation patterns and affect crop yields and local ecosystems, and it found that human-attributable changes in temperature and precipitation are now occurring in 80% of the world's land area, where about 85% of the global population resides, Callaghan said.

The impacts will be felt the strongest in the least developed countries, but little is known about exactly what those effects will look like, he added, describing the lack of data as an "attribution gap" that needs to be filled.

"In high income countries, almost all of those people live in an area where there is also lots of evidence about how that warming trend affects other systems," he said. "But in low income countries... there is little evidence about how that warming trend is affecting other things."

The new research is allowing scientists to attribute with near-certainty that global temperatures are increasing because of human influence on the planet, Callaghan said. While previous studies often focus on possible scenarios by 2050 or 2100, it is clear that climate change is "already happening."

Countries will need to significantly reduce greenhouse gas emissions in the near future to mitigate the extremity of pending disasters, the researchers said.

"As long as we continue burning fossil fuels, things will get worse," Callaghan said. "Until we reach net-zero, things will continue to get worse."
