Which factors contribute to climate change? Why scientists believe that people are to blame?

The global warming and climate change crises have long been among the most alarming issues for which people are currently struggling to come up with solutions. Truth be told, the people themselves are also the cause of such. People contribute to these problems every day, which makes them worse. For instance, based on the studies of the U.S. Environmental Protection Agency, the release of emissions into the atmosphere from burning fossil fuels to transport people and commodities, as well as to produce energy, has the greatest impact on the planet's current issue, climate change.

In the same way that a greenhouse keeps tropical plants alive in the cold, carbon dioxide and other naturally occurring gases have always existed in the atmosphere and have kept the planet warm. Ice cores, sediments, and tree rings all reveal the "greenhouse effect" to scientists.

Measurements made today reveal increased CO2 emissions. At the Mauna Loa Observatory in Hawaii, for example, the amount of carbon dioxide in the atmosphere has increased from 316 parts per million to 417 parts per million since 1958.

The alteration, on the other hand, could appear negligible when calculated in such tiny units. NASA and others claim that the changes are having an outsized impact on global average temperatures since CO2 has increased by more than 30%.
