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.

Castle Dale is a small town in central Utah. My grandpa’s farm is a few miles to the north. I grew up there. Milking a cow, feeding the chickens and cutting firewood were daily routines. Grandpa had me carrying a broom to do snow cleaning when it was actually taller than I was. This was the work kids like me learned to do at a young age.
I was tall, very tall at a really young age. My unusual height caused people to look, ask questions, laugh, tease, and sometimes even challenge me to fight. I was teased cruelly as a kid. It wasn’t fair, I knew, but that was just the way it was. Luckily, I was taught at a very young age a very important lesson. I am different and that’s Okay—I’m unique and I matter. No one could ever take that away from me. I knew this then, and I know this now. That alone helped me through the frustrations and heartaches of normal life.
When I was in junior high school, I realized something else that helped me cope. Most teasing came from one of two places—people who were either jealous or ignorant (愚昧). I couldn’t change the way they were, but I could change the way I felt. I was not going to feel bad because of their ignorance or jealousy. It wasn’t worth it. Realizing this didn’t stop them, or change the fact that these comments hurt. It did, however, give me a way to understand these people and deal with their treatment in a way that was okay for me.
These things still happen today. It will probably happen the rest of my life. I will always be 7 feet, 6 inches (2.29 meters) tall. I wouldn’t change that for anything. People will always look because it is not every day that you see someone that tall. I learned that at a young age and I now try to teach my own children that they are unique and they matter. That is the message I give to you. Regardless of your race, religion, background, or circumstances ... Being different is okay.
