Climate change in northwest China over the past millennium
Around half of the world’s population lives under the influence of the Asian monsoons. The sustainability of water resources, which is intimately tied up with future monsoon variability, is a critically-important issue in northwest China where development is taking place at the margins of agricultural productivity and towards the fringe of the landward penetration of summer monsoon rainfall. Understanding the likely future behaviour of the Asian monsoons is therefore critical for the people of

1.3.5 Corporate connections

As I mentioned in Section 2, what was happening in the factories of overseas contractors was said to have appeared remote to most, if not all, the chief executive officers of the clothing multinationals in the 1980s. Overseas contractors were selected on the basis of market price, quality and reliability, not on whether forced or child labour happened to be employed to stitch the product together. However, all that changed in the early 1990s when the geographical ties between the big retailer

1.2 The main classes of stars

The main classes of stars are shown in Figure 5.

The main sequence is 'main' in the sense that about 90% of stars fall into this class, and 'sequence' in the sense that it is a long, thin region that trails across the H-R diagram, covering a very wide range of temperatures and luminosities. The Sun is a main s

Carbon Capture and Storage: What Are the Big Issues and Opportunities for Future Energy Resources?
By: RASEIBoulder Summary: Carbon Capture and Storage (CCS) can make significant cuts in Greenhouse Gas emissions and will need to be part of the forward planning for developing future global energy resources. CCS technology comprises a number of steps: 1) CO2 is captured at the source (e.g., a power plant or gas production facility); 2) the captured CO2 is compressed to a supercritical state and transported, typically via pipeline, from the source to the geologic storage site; 3) the CO2 is inje
