Holocene warming trends in lake sediment analysis, deciphering tropical Australian climates for 10, 400 years.
Credit: Pixabay/CC0 Public Domain Understanding how Earth’s climate naturally fluctuated during the Holocene, a current geological age of 11,700 years, is important to contextualize modern human-driven warming and improve forecasts of future climate. However, the history of tropical Australia’s climate remains unknown, and scientists are often divided into interpretations of the paleoclimate record. To investigate this, a research team led…

Mixed forests can reduce the risk of forest damage in warm climates
According to extensive data analyzed by researchers, mixed forests reduce damage to trees. Credit: Jan Bengtsson Forests with few tree species are at much greater risk of damage, and introduced lodgepole pines are particularly vulnerable. This is the result of a new study published in Ecosphere by researchers from Umeå University and the Swedish University of Agricultural Sciences (Uppsala). The…
