How can that climate zone be best prepared for severe weather?
Which climate zone is the safest to live in? Why?

Answers

Answer:  1. It just depends on what climate, for example Higher temperatures mean warmer seas, higher sea levels and more moisture evaporating into the atmosphere.

2. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities.

3. Prepare by making sure that everything will stay in the same spot and check the forecast.

Answer:

Is it any two or is it specific? If so....

Explanation:

Sometimes, both plants and animals can physically change when there is a change in temperature or environment. For example, some plants are really good at surviving in drought-like conditions (cacti). The spikes on the cactus collect water to store for the cactus. Other times, animals (such as the whale or polar bear) have extra thick fur or blubber as insulation when it gets cold. Brrrrrr.
