Detailed explanation-1: -Because of the persistence of heritable diversity and differential survivorship and reproduction, natural selection is still there to promote new adaptations suited to the new environmental conditions. This means that when the environment changes, the distribution of traits in the population will often change as well.
Detailed explanation-2: -Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions.
Detailed explanation-3: -Adaptations are the result of evolution. Evolution is a change in a species over long periods of time. Adaptations usually occur because a gene mutates or changes by accident! Some mutations can help an animal or plant survive better than others in the species without the mutation.
Detailed explanation-4: -Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil and gas.
