New perspectives regarding the possible cooling of the Earth’s climate as a result of solar changes are reviewed in this paper. The major findings include: (1) solar activity is weakening to its very low level, which is comparable with the level in the early 20th century; (2) the current grand solar maximum has already lasted for eight 11-year solar cycles and might end in the coming one/two 11-year cycles; (3) a grand solar minimum might prevail in the next 100–200 years; and (4) the number of sunspots in the coming solar maximum (M)-year, around 2013, is an important indicator that needs to be closely monitored.

Procter & Gamble (P&G) has opened a manufacturing plant in Singapore for its Pur sachet in order to react quickly to disaster-prone nations in the region. Each four-gram sachet can turn 10 litres of dirty water into clean drinking water. The two primary components are ferric sulfate, a well-known and widely-used coagulant, and calcium hypochlorite, a disinfectant.

Predicting the response of the Greenland Ice Sheet to future climate change presents a major challenge to climate science. Paleoclimate data from Greenland can provide empirical constraints on past cryospheric responses to climate change, complementing insights from contemporary observations and from modeling. Here we examine sedimentary records from five lakes near Jakobshavn Isbræ in central West Greenland to investigate the timing and magnitude of major Holocene climate changes, for comparison with glacial geologic reconstructions from the region. A primary objective of this study is to constrain the timing and magnitude of maximum warmth during the early to middle Holocene positive anomaly in summer insolation. Temperature reconstructions from subfossil insect (chironomid) assemblages suggest that summer temperatures were warmer than present by at least 7.1 ka (the beginning of the North Lake record; ka = thousands of years before present), and that the warmest millennia of the Holocene occurred in the study area between 6 and 4 ka. Previous studies in the Jakobshavn region have found that the local Greenland Ice Sheet margin was most retracted behind its present position between 6 and 5 ka, and here we use chironomids to estimate that local summer temperatures were 2–3 °C warmer than present during that time of minimum ice sheet extent. As summer insolation declined through the late Holocene, summer temperatures cooled and the local ice sheet margin expanded. Gradual, insolation-driven millennial-scale temperature trends in the study area were punctuated by several abrupt climate changes, including a major transient event recorded in all five lakes between 4.3 and 3.2 ka, which overlaps in timing with abrupt climate changes previously documented around the North Atlantic region and farther afield at ∼4.2 ka.
