Climate field reconstructions from networks of tree-ring proxy data can be used to
characterize regional-scale climate changes, reveal spatial anomaly patterns associated …

This review of late-Holocene palaeoclimatology represents the results from a
PAGES/CLIVAR Intersection Panel meeting that took place in June 2006. The review is in …

The temporal link between mass extinctions and large igneous provinces is well known.
Here, we examine this link by focusing on the potential climatic effects of large igneous …

Global warming is one of today's greatest challenges. The science of climate change leaves
no doubt that policies to cut emissions are overdue. Yet, after twenty years of international …

Evidence of the effect of external influences on the climate system has continued to
accumulate since the Third Assessment Report (TAR). The evidence now available is …

Understanding natural causes of climate change is vital to evaluate the relative impacts of
human pollution and land surface modification on climate. We have investigated one of the …

To evaluate the effects of stratospheric geoengineering with sulphate aerosols, we propose
standard forcing scenarios to be applied to multiple climate models to compare their results …

Climate geoengineering proposals seek to rectify the current radiative imbalance via either
(1) reducing incoming solar radiation (solar radiation management) or (2) removing CO 2 …

Large volcanic eruptions are an important driving factor of natural climate variability. A
sound assessment of the role of volcanoes in the climate system in comparison to other …

Climate geoengineering proposals seek to rectify the Earth's current and potential future
radiative imbalance, either by reducing the absorption of incoming solar (shortwave) …
