What are some possible future changes in the global climate?
Ugo [173]

The most probable future changes in the global climate are:

- Global warming;

If the levels of CO2 and methane increase enough in the atmosphere to be able to intensify the Greenhouse effect, than some portion of the ice on the planet will melt because of the rising temperatures, thus lifting up the sea level, creating more unpredictable weather with larger and stronger storms, but also making the mainland much drier. This would be a scenario if the continents are arranged like they are now, but if there isn't a sufficient mass of land on and around the poles, than all of the ice will melt and the sea levels will rise so much that the planet will come in the ''water planet'' scenario, and it will have wet tropical climate pretty much everywhere on the planet.

- Ice Age;

If there's a disruption in the warm ocean streams and some of them disappear, or the levels of nitrogen or oxygen increase in the atmosphere, the Earth will start to cool off, thus coming to a situation of an Ice Age. In this kind of situation, there will be large ice sheets on and around the poles that are stretching much further towards the lower latitudes, as well as mountains all over the world that are covered in snow and shaped by glaciers.

Is the statement "I joined the science club to make my parents happy" intrinsic motivation
Bess [88]
Depends on whether the person is talking to themselves, or someone else.
If they are talking to themselves, it is indeed intrinsic motivation, as they are convincing themselves they are also happy and motivated to join the science club as it makes their parents happy.
If they are talking to someone else, it would not be intrinsic motivation. This is because they are merely telling someone that they're doing something to make their parents happy.
As it is a statement, on the whole I would say, no. It is not intrinsic motivation.
