This chapter looks at how the Sun varies in terms of its emissions of radiation and particles and how these changes might be associated with variations in weather and climate on Earth. Investigations of climate variability and climate change depend crucially on the existence, length, and quality of meteorological records. Ideally, records would consist of long time series of measurements made by well-calibrated instruments densely situated across the globe. For longer periods, and in remote regions, records have to be reconstructed from indirect indicators of climate known as proxy data. The chapter introduces one well-established technique for providing proxy climate data: dendrochronology, or the study of the successive annual growth rings of trees.

This introductory chapter provides an overview of the Earth's climate system—its composition, structure, and circulation—and some of the ways in which these vary naturally with time. It examines the key features of the structure of the Sun, its magnetic field, atmosphere, and its emission of radiation and particles. A comprehension of how the sun affects the Earth is a fundamental requirement for understanding how climate has varied in the past and how it might change in the future. This is particularly important in the context of determining the cause(s) of climate change and understanding natural factors in order to be able to attribute to human activity any past or potential future influence on a range of timescales.

The atmosphere is the thin, diffuse fluid that envelops the Earth’s surface. Despite its apparent fragility, the existence of this fluid is vital for human and other life on Earth. The Atmosphere: A Very Short Introduction describes the physical and chemical characteristics of different layers in the atmosphere, and shows how the atmosphere’s interactions with land, ocean, and ice affect these properties. It also looks at how movement in the atmosphere, driven by heat from the Sun, transports heat from lower latitudes to higher latitudes. Finally, it presents an overview of the types of measurements used to understand different parts of the atmosphere, and identifies future challenges in the light of climate change.

The comparative and extrospective nature of contemporary urban policy-making is one that has demanded our attention in recent years. Relatively long established and formal inter-urban networks of professionals of one sort or another have been joined by activists, consultants, financiers, lawyers and think tankers who have involved themselves in the arriving at, and making up of, urban policy. Through conferences, documents, knowledge banks, policy tourism, power-points and webinars, an emergent informational infrastructure has emerged to shape and structure the circulations and making of policy-making across a numbers of areas. From aging to creativity, climate change to drugs, education to transport, urban policies in different spheres have been rendered mobile. There is political work of adaptation, mediation and translation that has to be done to move policies from one location to another, of course. In some cases these policies appear in a range of locations, while in others they do not, a reminder – if one was needed – that those involved in the making up of policy are not always able to render all elements of the future under their control. This emphasis on the relational and territorial geographies of global-urban policy-making captures some of the issues facing those who lead cities. This paper sets out some of the intellectial challenges for those working on these issues, highlighting some potentially fruitful ways forward, illustrating the main arguments through the use of Tax Increment Financing, a financial value-capturing model.

Abstract There is considerable evidence for solar influence on the Earth's pre-industrial climate and the Sun may well have been a factor in post-industrial climate change in the first half of the last century. Here we show that over the past 20 years, all the trends in the Sun that could have had an influence on the Earth's climate have been in the opposite direction to that required to explain the observed rise in global mean temperatures.
