This research paper is the first time that a tipping point of a switch from a carbon sink to a carbon emission source in tropical rainforests has been identified clearly – not just for one year but for the last 20 years. Cause is a change in the local climate. www.theguardian.com/environment/...

Forest loss is driving mosquitoes’ thirst for human blood
In the rapidly disappearing Atlantic Forest, mosquitoes are adapting to a human-dominated landscape. Scientists found that many species now prefer feeding on people rather than the forest’s diverse wildlife. This behavior dramatically raises the risk of spreading dangerous viruses such as dengue and Zika. The findings reveal how deforestation can quietly reshape disease dynamics.
