Small shallow estuaries face enhanced flood risk under climate change because of sea-level-rise-induced tidal amplification. In contrast, large deep estuaries are threatened by sediment starvation and therefore a loss of intertidal area. Both cases can potentially be mitigated by estuary widening (by Nature Climate Change).
Future emissions scenarios for the IPCC Sixth Assessment Report should explore the carbon budget space in a systematic manner, which would be robust to the updates of latest climate science, so that policy implications can be adequately assessed (by Nature Climate Change).
There are major gaps in how food waste in tourism is understood and calculated, according to researchers at the University of Eastern Finland and the University of Southern California. Food waste originating from hotels, restaurants and events is recognised and can be estimated and calculated, but as the tourism industry is becoming more and more diverse, so are the sources of its food waste (via Earth News)..
Permafrost thaw due to rising temperatures will impact soil hydrology in the Arctic. Abrupt changes in soil moisture and land–atmosphere processes may alter the bearing capacity of soil and increase susceptibility to wildfires, with consequences for adapting engineering systems in the region (by Nature Climate Change).
The resilience of a marine food web to climate change is investigated through a combination of multiple and nested species interactions. The Kongsfjorden food web adapts and maintains core ecological processes during change, with increasing dominance of Atlantic species boosting resilience (by Nature Climate Change).
The Netherlands is unlikely to reach its target of reducing greenhouse gas emissions by 49% by 2030 despite a tough package of measures agreed in June (via Earth News).
The United States formally notified the United Nations that it was withdrawing from the Paris climate accord, making the world’s largest economy the sole outlier from the agreement.
