There is no ozone layer for plants to survive and the temperatures change drastic.
A species that is genetically diverse is more likely to survive in the event of a major change in it's environment, because of chance. A large swing in climate for instance, could entirely wipe out a species that was solely suited to a specific climate. However, if a portion of the species is more adaptable to a colder climate, and a portion is more adaptable to a warmer climate, even though a climate change would mean death for a large portion, a portion would be more likely to survive.
Yes- they are accustomed to the arctic climate, they could not survive in warmer waters.
Some scientists think the human race has a 50:50 chance of surviving beyond 2100 if climate change continues.
a change in climate means that certain plants may not be able to survive. this then causes a decrease in herbivores, and then a decrease in carnivores because of the lack of food.
Species can change is there is a mass extinction or if the type of species changed the type of climate or terrain which would would make the species evolve to its new environment so that it can survive.
It is possible for a species to survive a climate change that happens slowly over a thousand years:The climate change may not be significant enough to harm the species.The species itself may be flexible enough to not be affected by the climate change,As the climate changes, those on the outer skirts of the climate change area may be attracted to more hospitable areas and survive. Those that don't move may perish.Each new generation may result in variations (mutations) to the species. Some of the variants may be able to live in the new climate conditions. Those that can't will perish.

The advantage is that if there is a change in the environment - climate change, new pathogen, etc. - more diversity makes it much more likely that some members of the species survive.

Yes, because climate change is so small that you don't notice it.
The cause of natural selection is a change in the environment of a species. This change can have many causes. E.g. climate change, introduction of a new species, flooding, etc. When such an environmental change occurs, the individuals which are the most fit will have the biggest probability to survive and change the relative gene frequency in a species' genetic pool.
Humans
Organisms change significantly, or evolve in biological terms, only when there is a need for significant change. An example would be a natural disaster occurring, causing the founder effect or vast changes in the environment. This change in the environment might force a species to evolve unable to survive; those who don't have the needed adaptation would die out, leaving the "survivors" to reproduce. If no drastic change that would cause a need for adaptation occurred through geological time that pertained to a certain species, then no drastic change in the species itself would occur.
An example for the dwindling number of many species would be deforestation. The events of deforestation have been escalated due to climate change, and have greatly diminished the habitats of many species, making it hard for them to survive.
A factor that tends to cause species to change can be one of two things. It can be either climate change or an invasive species.
a model of evolution in which short periods of drastic change in species are separated by long periods of little or no change
