What makes the current global warming trend different from normal climate cycles of the past?

Answer 1

There are more greenhouse gases in the air, such as #"CO"_2#.

The Greenhouse Effect has been around for a long time, and is what helps keeps the earth warm enough to keep us from freezing to death.

In today's world, however, the greenhouse effect has become enhanced from carbon emissions, to where it is becoming warmer than it should, leading to climate change, increased temperatures, and other problems.

The current global warming trend is primarily driven by human activities, particularly the burning of fossil fuels, deforestation, and industrial processes, which release greenhouse gases into the atmosphere at unprecedented rates. This amplifies the natural greenhouse effect, leading to accelerated warming. Additionally, the rate of temperature increase is much faster compared to past climate cycles, which allows ecosystems and species less time to adapt.
