North American boreal forests are subject to strong disturbances, both natural and anthropogenic5,48. On a continental scale, the dominating sources of disturbance are wildfires and timber harvest49. We therefore compared tree cover changes in areas affected by wildfire44,50,51 and areas that were...
We conclude that the main trends are attributable to the carbon isotope signature acquired through rain equilibration with soil gas and bedrock dissolution, rather than in-cave processes such as prior calcite precipitation (Methods). Multiproxy process modeling suggests that this correlation arises ...
