To some extent, global warming is a natural event. Carbon dioxide is a naturally occurring greenhouse gas. At normal concentrations, it, along with other greenhouse gases, helps maintain global temperatures at a level that is comfortable for humans and other animals that have adapted to the present climate. Throughout human history until the Industrial Age, atmospheric carbon dioxide levels were in the range 260-280 parts per million (ppm) and never higher than this. This is the natural part of global warming.
By adding new carbon dioxide to the atmosphere, which we do by burning fossil fuels such as coal, oil and natural gas, and by cement manufacture, we interfere with the natural process and create enhanced global warming, which is not natural.

How is global warming happening
Global warming is not natural, it is caused by people. Since there aren't people on Neptune, it cannot have global warming.
Global warming may change local climate and natural balance in some parts of the earth. Some animals can not survive the change in their environment. Animals will not kill as a response to global warming. Animals kills for food or territorial reasons.
The idea that Global Warming is a natural cycle is well understood from paleo.
Burning natural gas contributes least to Global Warming.
No, volcanoes would have nothing to do with global warming in any measurable way. Volcanoes occur for reasons outside of the issues involved with global warming.
Floods, and because of global warming they have increased.
The theory of global warming became popular in the early 70's. As for how old actual global warming is, is debatable. Some argue that global warming is a natural cycle the earth goes through every so many centuries.
Global warming
WHY? For the very best of reasons - FACT.
Global warming lowers the amount of cold climate habitat in the world. This is the natural habitat of the gray wolf.
