There is no causal connection between global warming and specific events, but there is a statistical relationship between extra energy in the atmosphere and more of these events. So strap in - we'll be seeing much more of this over the next 100 or so years.
Weight reduction efforts in cars and weight increase efforts in humans - which one wins?
It takes energy to accelerate a mass, so having less mass to accelerate makes sense if you want to use less fuel. But while people have gained weight and great efforts have been made to reduce the weight of car compenents, there is another trend that swamps both of them. Cars have become much heavier for a variety of other reasons - larger engines, crash resistance, creature comfort and so on... Cars that weighed under 3,000 pounds were common in the 60s, now most are well above 3,500.
Some practical cars in the 2,000 pound range are appearing and much lighter designs have been demonstrated. Widespread appeal of cars like the VW Go! is unlikely in the US unless gas prices rise dramatically and stay up.
We've been part of several class action suits. The net result is usually millions for the lawyers and mostly nothing to the original consumers.
This is an interesting approach - the use of small claims court to remove the lawyer advantage of large companies. If the approach works I'm sure it will be made illegal somehow as it would represent a shift of power to the consumer.
Since I've been fairly successful in losing some weight in the last year I'm finding people are asking for tips. What has worked for me involves carefully tracking of exercise and food intake. Restaurants can be a challenge and involve guessing - sometimes you make a wild guess and try to be conservative, but guides help.
For Chinese restaurants I use a guide from the Center for Science in the Public Interest. Their numbers square with other measurements I've seen although they don't have careful nutrition breakdowns, portion sizes, or other variations that happen .. just a good starting spot for somewhat better guessing.
