Climate change has been partially mitigated by an increasing net land carbon sink in the
terrestrial biosphere; understanding the processes that drive this sink is thus essential for …

Drought-associated woody-plant mortality has been increasing in most regions with multi-
decadal records and is projected to increase in the future, impacting terrestrial climate …

The possibility that the Amazon forest system could soon reach a tip** point, inducing
large-scale collapse, has raised global concern,–. For 65 million years, Amazonian forests …

Climate tip** points occur when change in a part of the climate system becomes self-
perpetuating beyond a warming threshold, leading to substantial Earth system impacts …

The uptake of carbon dioxide (CO2) by terrestrial ecosystems is critical for moderating
climate change. To provide a ground-based long-term assessment of the contribution of …

Forest ecosystems depend on their capacity to withstand and recover from natural and
anthropogenic perturbations (that is, their resilience) 1. Experimental evidence of sudden …

Recent observations of elevated tree mortality following climate extremes, like heat and
drought, raise concerns about climate change risks to global forest health. We currently lack …

Enhancing the terrestrial ecosystem carbon sink (referred to as terrestrial C sink) is an
important way to slow down the continuous increase in atmospheric carbon dioxide (CO2) …

ES 6: 3-5 Replace “It is unequivocal that emissions of the well-mixed greenhouse gases
(GHG) carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2 O) from human activities …

Chapter 2, building on prior assessments, provides a global assessment of the observed
impacts and projected risks of climate change to terrestrial and freshwater ecosystems …
