What allows scientists to predict future climate change with some sense of accuracy?

a Extinctions of ancient plants and animals can reveal what is likely to happen in the future.

b Ice cores can show the composition of the atmosphere in the past.

c Climate models can show the composition of the atmosphere in the future.

d Climate models can show the interactions between all Earth’s subsystems in the past.

Climate models can show the composition of the atmosphere in the future.

Explanation:

Climate models help predict how the average conditions will change in a region and they also serve as an extension of weather forecasting. They are quite broad and can make analysis and predictions over long time spans.

These models are generated from some set of mathematical principles with different data points numbering over a thousand. These large data points help increase the accuracy of the models.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
