How is the climate now?
Climates can be variable and depends on where you live. It is spring now, yet it is cold raining and even snowing in Europe. Please specify the country and region for a correct answer
Climate is a term that describes the general conditions of temperature, wind, humidity, precipitation, etc, of a region. Climate does not have specific types of animals. Now, if you specify a particular climate, such as tropical savannah, or arctic tundra, than you can talk about the animals that are typically found in such climate zones.
We prefer the term global climate change to "global warming" now. And no, it is not a theory. It is a fact. Global climate change is happening. Right now. While it is true that the global climate of the earth changes over time (we've had ice ages, haven't we?), the speed of that change is alarming when we look at the present. And it is man that is causing it to change so rapidly.
