We all think plants were expected to get larger with increased carbon dioxide in the atmosphere, but changes in temperature, humidity(湿度)and nutrient availability seem to have trumped the benefits of increased carbon dioxide" said researchers from the National University of Singapore.
45 percent of the species studied now reach smaller adult sizes than they did in the past. The researchers pointed out that warmer temperatures and changing habitats, caused by climate change, are possible reasons for shrinking creatures.
" We do not yet know the mechanisms(机制)involved, or why some organism are getting smaller while others are unaffected," the researchers said. "Until we understand more, we could be risking negative consequences that we can't yet quantify."
The change is big in cold-blooded animals. Only two decades of warmer temperatures are enough to make retiles (爬行动物)smaller. An increase of only 1 degree centigrade caused nearly a 10 percent increase in metabolism(新陈代谢). Greater use of energy resulted in tiny tortoises and little lizards. Fish are smaller now too. Though overfishing has played a part in reducing numbers, experiments show that warmer temperatures also stop fish growing.
Warm-blooded animals aren't immune(免除)from the size change caused by climate change. Many birds are now smaller. Soay sheep are thinner. Red deer are weaken And polar bears are smaller, compared with historical records.
This is not the first time this has happened in Earth's history. 55 million years ago, a warming event similar to the current climate change caused bees, spiders and ants to shrink by 50 to 75 percent over several thousand years. That event happened over a longer time than the current climate change.
The speed of modem climate change could mean organisms may not respond or adapt quickly enough, especially those with long generation times climate change will be shown in the future.

It's probably my favourite bookstore ever. It's "designed for travelers who like reading". It is famous for its travel book collection. Categorized by country and region, you can find books on history, arts, food, culture, film, literature, and many more topics of the region. It's absolutely fascinating. My favourite is the London literature section near the entrance. It's very tasteful selection and it's a pleasure just to read a few paragraphs while you browse (浏览). The interior is beautiful. Classic wooden counters, wooden floors, shelves and tables of book are organized nicely. Every time I passed by I had to make a stop there. Staff there are helpful and friendly.
I love the convenience of Amazon but bookstores with special atmosphere like this just cannot be replaced.

I don't read books as often as I would like. I just don't have time, and let's be honest, after doing all my schoolwork. I'd rather just put my brain on coast and read an OK magazine and catch up with some news about film stars. I was brought into Daunt while wandering down the street and it's really just an inspiring place and it actually made me want to "read" something. Really, if you're anywhere near the shop, do pop in and just look around, even if you have a love/ hate relationship with reading like I do. The inside of the shop made me look around as if I remember enjoying as a kid seeing some new big store, when in fact it's not new, but the sight of a bookstore with classic design charm is refreshing after spending so much time in libraries.
Go and see it for yourself. You won't be disappointed!
