The changes aren't the same throughout the rainforest. The south-eastern part of the Amazon has already changed to the point at which it is now a carbon emitter (释放者) rather than a carbon sink. Matt Finer at the Amazon Conservation non-profit organization says the research could help ...
respectively20. However, Hellen et al.20, also reported seasonal changes of such sensitivities in the boreal forest; so that the sensitivities obtained in this work may be a lower limit for temperature driven emissions in the tropical forest. Reporting ambient mixing ratios and not leaf-level con...
Other Amazon experts say the research adds to a growing body of evidence that the rainforest is approaching a tipping point. The changes aren't the same throughout the rainforest. The south-eastern part of the Amazon has already changed to the point at which it is now a carbon emitter ...
Tropical birds deep in Brazil’s Amazon rainforest are shrinking and developing longer wings as they adapt to climate change.Researchers studied data for 77 tropical bird species over the past 40 years and found that all of them had lost body mass, with some species losing nearly 2 ...
Marked coastal environmental changes occurred at around 3630 year BP, driven by sea-level transgression. Mangroves expanded again, and were close to the site. The local palm swamp was replaced by a Cyperaceae (sedge) swamp. Rainforest and coastal Restinga vegetation adjacent to the swamp were ...
根据倒数第二段“Victor Brovkin at the Max Planck Institute for Meteorology in Germany says the teleconnections are an interesting find, but is skeptical that variability in the Amazon rainforest causes the changes elsewhere. (德国马克斯·普朗克气象研究所的维克多·布罗夫金说,这种远程关联是一个有趣...

Tropical(热带的)birds deep in Brazil’s Amazon rainforest are shrinking as the world’s climate changes. Researchers studied data for 77 tropical bird species over the past 40 years and found that all of them had lost body mass, with some species losing nearly 2% of their weight per decade...
The Amazon rainforest has evolved over millions of years and even through ice ages. Yet today, human influences and global climate change put this huge ecosystem at risk of large-scale dieback—with major consequences for its capability as a global CO2 s
The researchers found that since 1979, warm temperatures in the Amazon rainforest were related to warm temperatures over the Tibetan plateau and the West Antarctic ice sheet; more precipitation in the Amazon rainforest was associated with less precipitation in those regions. By analyzing changing temp...
