The gang discusses two papers that look at how species respond to climate change. The first paper uses models to study how bird migration patterns may have changed over the last 800,000 years, and the second paper looks at how blooming times for plants in the UK have changed over the last 300 years. Meanwhile, James and Amanda prepare for a trip (2 months ago), and Curt is left a little confused.
Up-Goer Five (Curt Edition):
Our friends talk about two papers that look at how living things can change when it gets hotter or colder across the world. The first paper looks at animals that can fly and some of them move around when it gets hot or cold during a year. This paper uses computers to look at how these animals may have changed how they move around during times that were colder and warmer than today. This is part of a bigger story where some people think that these animals moving around during the year is something that might be pretty new, since the last time we warmed up. The computers say that these types of animals were probably still moving around during these colder times, and that there are some cool things about how where theses animals are might have changed how they moved over time, since some places got colder than others.
The second paper looks at green things that make their own food. These green things start to grow and make the things they need to make babies during the warm parts of the year. Some of them use light, but a lot of them use how warm it is to know if it is time to start growing again. For this one part of the world, they have been looking at these green things for almost 300 years. When we look at when these green things start growing, we are seeing them start growing earlier in the year than they did in the past. This is not happening every place in the same way and not to every type of green thing. But all of these changes all show the same idea; that the world is getting warmer and these green things are starting to grow earlier in the year because of it, and places that are getting warmer faster and seeing those green things grow even earlier.
