Trees and land absorbed almost no CO2 last year. Is nature’s carbon sink failing?

“The issue of natural sinks has never really been thought about properly in political and government fields. It’s been assumed that natural sinks are always going to be with us. The truth is, we don’t really understand them and we don’t think they’re always going to be with us. What happens if the natural sinks, which they’ve previously relied on, stop working because the climate is changing?” says Watson.
