Climate change: how the jet stream is changing your weather; Feeling rich? Wealth is all relative

• As the world gets warmer, the behaviour of the jet stream is one of the most studied mysteries of climate change. Scientists are trying to understand how this current of air is changing, and whether it will get stronger or weaker — which holds big implications for weather patterns, crop yields and rising sea levels
• The persistent heat has been melting the permafrost layer under the soil in regions like Greenland, causing roads to buckle and house foundations to shift, and necessitating expensive repairs
• As scientists’ race to solve the jet stream puzzle, the risk is that the models are not able to forecast it sufficiently over the long term, to prepare for the changes it will bring

• At national level, to be in the top 1 percent of men requires an income of £200,000, while to be among the top 1 percent of women requires an income of half that
• Top earners are disproportionately likely to be in their late 40s or early 50s, reflecting the fact that earnings generally peak in the latter half of a career
• The skew towards male, middle-aged Londoners is even stronger at higher income levels. Almost half of the top 0.1 percent of taxpayers are in London, more than 40 percent are aged 45-54 and only 11 percent are women
