A new hypothesis for the 1470-year cycle of abrupt warming events in the last ice-age
… is presented for the glacial 1470-year climate cycle, which manifests itself in abrupt warming events (the socalled Dansgaard-Oeschger events, or DO events). According to the hypothesis, two century-scale solar cycles could explain the regularity in the timing of the DO events, since the …

Uncertainty and learning in sequential decision-making : the case of climate policy
The debate over a policy response to global climate change has been and continues to be deadlocked between 1) the view that the impacts of climate change are too uncertain and so any policy response should be delayed until we learn more, and 2) the view that we cannot wait to resolve the …

Estimating global warming from anthropogenic heat emissions
… heat flux (AHF), i.e. the dissipation of primary energy consumed by the human civilisation, produces a direct climate warming. Today, the globally averaged AHF is negligibly small compared to the indirect forcing from greenhouse gas emissions. Locally or regionally, though, it has a …

Constraining uncertainty in climate sensitivity : an ensemble simulation approach based on glacial climate
Uncertainty about the sensitivity of the climate system to changes in the Earth’s radiative balance constitutes a primary source of uncertainty for climate projections. Given the continuous increase in atmospheric greenhouse gas concentrations, constraining the uncertainty range in such type of …
