For obtaining an adequate amount of DNA samples for DNA fingerprinting, polymerase chain reaction (PCR) can be used.
Polymerase chain reaction (PCR) is a technique that is used to amplify the DNA sample. The steps included in PCR are:-
1. Denaturation of the double-stranded DNA (at around 95°C)
2. Annealing of the primers to each of the single-stranded DNA templates ( at around 65°C)
3. Extension or elongation of the primers by considering every single-stranded DNA as a template. This elongation is carried out by <em>Taq </em>polymerase (at around 72°C).
With each cycle of PCR, the DNA sample is increased by 2ⁿ. Here, 'n' represents the number of PCR cycles.

The answer is; Carbon dioxide levels in the Earth’s atmosphere have been steadily increasing.
Data has shown a direct relationship between the increase in the levels of carbon dioxide in the atmosphere and rising global temperatures. The rise in the global temperatures can be observed through the melting of Arctic and Antarctic glaciers, the rise in ocean levels, and extreme weather events.
