CLIMATE CHANGE, CAUSES. To summarize evidence discussed elsewhere in this volume, past climate change can be detected on time scales of decades to hundreds of millions of years. Theories as to the causes for such changes extend back almost as far as the observations. James Croll (1867) was the first to

Key Points. There is a scientific consensus that concentrations of greenhouse gases in the atmosphere are increasing and that this is causing global climate change. Human-driven emissions of carbon dioxide and other greenhouse gases, as well as land-use change, are the processes primarily responsible for the increase
Abstract. The aim of the paper is to provide a clear and thorough conceptual analysis of the main candidates for a definition of climate and climate change. Five desiderata on a definition of climate are presented: it should be empirically applicable, it should correctly classify different climates, it should not depend.

Evidence & Causes Attributing extreme weather events to climate change is challenging because these events are by definition rare and therefore hard to evaluate reliably, and are affected by patterns of natural climate

In BACC, we address the problem of “climate change", which is unfortunately differently understood in different quarters (e.g. Barring 1993; Pielke 2004). The problem is that. “inconstancy" (Mitchell et al. 1966) is an
