Modern cargo ships slow to the speed of the sailing clippers | Environment | The Observer
A combination of the recession and growing awareness in the shipping industry about climate change emissions encouraged many ship owners to adopt "slow steaming" to save fuel two years ago. This lowered speeds from the standard 25 knots to 20 knots, but many major companies have now taken this a stage further by adopting "super-slow steaming" at speeds of 12 knots (about 14mph).

Travel times between the US and China, or between Australia and Europe, are now comparable to those of the great age of sail in the 19th century. American clippers reached 14 to 17 knots in the 1850s, with the fastest recording speeds of 22 knots or more.

Maersk, the world's largest shipping line, with more than 600 ships, has adapted its giant marine diesel engines to travel at super-slow speeds without suffering damage. This reduces fuel consumption and greenhouse gas emissions by 30%. It is believed that the company has saved more than £65m on fuel since it began its go-slow.

Rising sea levels | A sinking feeling | The Economist
"scientists now reckon that sea levels will rise by between 50cm and 100cm by 2100, unless action is taken to curb climate change". At this point it's too late to reverse, best we can hope for is to return the earth to sense before 3000.

A green New Deal? | Green, easy and wrong | The Economist
This article commends financial penalties for pollution but not financial incentives for clean energy ("subsidies"). "Subsidising clean energy requires politicians to decide the best way of delivering clean energy, and their judgement is likely to be worse than the market's". Can a government subsidise clean energy across the board, without preempting the market by preferring one over another? I'd say so.

You will boggle at the ideas. For example, pumping millions of tons of poisonous SO2 into the atmosphere, where it will mix with water to make sulphuric acid and other good things. Yes, acid rain is much better than global warming! Not. Other ideas: silver nanobots in space, and unmanned craft making ocean clouds.

Business and water | Running dry |
An article full of astonishing water use figures. Global consumption is doubling every 20 years. Takes 13 cubic metres of water to make a single 200mm semiconductor wafer, and chipmaking thought to be 25% of Silicon Valley's water consumption. 40% of US freshwater from lakes and aquifers used to cool power plants, and 1L of oil from tar sands takes 5L of water. 90% of Chinese rivers near urban areas are seriously polluted. Dow, Nestle, and Coca-Cola are working to reduce use and emit less (none, in Coca-Cola's case) pollution.
