Anthropogenic climate change is decreasing seasonal snowpacks globally, with potentially
catastrophic consequences on water resources, given the long-held reliance on snowpack …

We assess evidence relevant to Earth's equilibrium climate sensitivity per doubling of
atmospheric CO2, characterized by an effective sensitivity S. This evidence includes …

Prudent risk management requires consideration of bad-to-worst-case scenarios. Yet, for
climate change, such potential futures are poorly understood. Could anthropogenic climate …

The social cost of carbon dioxide (SC-CO2) measures the monetized value of the damages
to society caused by an incremental metric tonne of CO2 emissions and is a key metric …

This chapter assesses simulations of future global climate change, spanning time horizons
from the near term (2021–2040), mid-term (2041–2060), and long term (2081–2100) out to …

Over the last five years prior to the Glasgow Climate Pact, 154 Parties have submitted new
or updated 2030 mitigation goals in their nationally determined contributions and 76 have …

Steady improvements in ambient air quality in the USA over the past several decades, in
part a result of public policy,, have led to public health benefits,,–. However, recent trends in …

The ambition and effectiveness of climate policies will be essential in determining
greenhouse gas emissions and, as a consequence, the scale of climate change impacts …

Carbon recycling will become a dominant trend toward alleviating extreme climate change
and coping with the increasing energy demand in the coming years. Solar-driven strategies …

Climate simulation-based scenarios are routinely used to characterize a range of plausible
climate futures. Despite some recent progress on bending the emissions curve, RCP8. 5, the …
