The complex political and social context where local and regional policies are being developed plays a decisive role in the development of climate change adaptation. This article examines the phenomenon of climate change adaptation in Dutch communities by focussing on the policy process of local adaptation to determine the main factors that drive policy actors in these municipalities to impleme...

[1] Past climates, such as the Eocene (55 38 Ma), experienced dramatically warmer polar winters. Global climate models run with Eocene-like boundary conditions have under-predicted polar temperatures, a discrepancy which has stimulated a recent hypothesis that polar stratospheric clouds may have been important. We propose that such clouds form in response to higher CO2 via changes in stratosphe...

Various clustering methods have been applied to climate, ecological, and other environmental datasets, for example to define climate zones, automate land-use classification, and similar tasks. Measuring the “goodness” of such clusters is generally application-dependent and highly subjective, often requiring domain expertise and/or validation with field data (which can be costly or even impossib...

Clouds play a crucial role in radiative energy budget and water cycle in the earth-atmosphere system. In order to understand such processes as global warming and to improve assessment of climate change, it is necessary to develop climate models, which properly take into account radiation and cloud processes. In addition, it is also important to improve satellite monitoring systems for measuring...

The role of tectonic Southern Ocean gateway changes in driving Antarctic climate change at the Eocene– Oligocene boundary remains a topic of debate. One approach taken in previous idealized modeling studies of gateway effects has been to alter modern boundary conditions, whereby the Drake Passage becomes closed. Here, the authors follow this approach but vary atmospheric pCO2 over a range of va...

Tidal inlets are of great societal importance as they are often associated with ports and harbours, industry, tourism, recreation and prime waterfront real estate. Their behaviour is governed by the delicate balance of oceanic processes (tides, waves and mean sea level), and fluvial/estuarine processes (riverflow and heat fluxes), all of which can be significantly affected by climate change (CC...

[1] I show that the latest series of climate models reproduce the observed mid-depth Southern Ocean warming since the 1950s if they include time-varying changes in anthropogenic greenhouse gases, sulphate aerosols and volcanic aerosols in the Earth’s atmosphere. The remarkable agreement between observations and state-of-the art climate models suggests significant human influence on Southern Oce...
