How much can we trust model-based projections of future anthropogenic climate change?
This review attempts to give an overview of this important but difficult topic by using three …

Water vapor is a greenhouse gas that dominates Earth's terrestrial radiation absorption. As
the planetary temperature warms, forced by increasing CO 2 and other greenhouse gases …

Equilibrium climate sensitivity, the global surface temperature response to CO doubling, has
been persistently uncertain. Recent consensus places it likely within 1.5–4.5 K. Global …

Marine low clouds strongly cool the planet. How this cooling effect will respond to climate
change is a leading source of uncertainty in climate sensitivity, the planetary warming …

Excessive precipitation over the southeastern tropical Pacific is a major common bias that
persists through generations of global climate models. While recent studies suggest an …

Global warming drives changes in Earth's cloud cover, which, in turn, may amplify or
dampen climate change. This “cloud feedback” is the single most important cause of …

We quantify forcing and feedbacks across available CMIP5 coupled atmosphere‐ocean
general circulation models (AOGCMs) by analysing simulations forced by an abrupt …

Feedbacks of clouds on climate change strongly influence the magnitude of global
warming,,. Cloud feedbacks, in turn, depend on the spatial patterns of surface warming …

This study diagnoses the climate sensitivity, radiative forcing and climate feedback estimates
from eleven general circulation models participating in the Fifth Phase of the Coupled Model …

This chapter assesses the capacity of the global climate models used elsewhere in this
report for projecting future climate change. Confidence in model estimates of future climate …
