Around half of ocean heat intake since 1865 has taken place since 1997, researchers report online in Nature Climate Change.Warmi

While the top of the ocean is studied, its depths are more difficult to (30)The researchers gathered 150 years of ocean temperature data in order to get better (31)of heat absorption
3、 from surface to seabed. They gathered together temperature readings collected by everything from a 19th century (32)of British naval ships to modern automated ocean probes. The extensive data sources, (33)with computer simulations(计算机模拟), created a timeline of ocean temperature changes, including c

9、the renewed focus on waistlines means that industry groups are under pressure to demonstrate their products are healthy as well as tasty.Over the past three decades, the industry has made some efforts to improve the quality of its offerings. For example, some drink manufactures have cut the amount o

More recently, however.Some companies have been investing money in a more ambitious undertaking: lear
11、ning how to adjust the fundamental make-up of the food they sell. For example, having salt on the outside, but none on the inside, reduces the salt content without changing the taste.While reformulating recipes(配方)is one way to improve public health, it should be part of a multi-sided approach. The
12、key is to remember thatthere is not just one solution. To deal with obesity, a mixture of approaches-including reformulation, taxation and adjusting portion sizes-will be needed.
