A climate change is defined as the variation in the state of the climate system, formed by the atmosphere, the hydrosphere, the cryosphere, the lithosphere and the biosphere, which lasts for sufficiently long periods of time (decades or longer) until a new Balance. It can affect both mean meteorological values as well as their variability and extremes.
Current climate change is very likely to be totally anthropogenic and is mainly related to the intensification of the greenhouse effect due to industrial emissions from the burning of fossil fuels. The probable contributions of natural forcings and internal variability to the change in global temperature since 1951 are negligible.
This is a bit tricky, but in general, it is climate change that is the source of the greatest disagreement among American politicians, because some people still think it doesn't exist.
International trade enables specialization, which brings increased efficiency and greater competition to spur the market.
