human impact
In the past global warming was natural in that humans lacked the technology to have much impact. Currently the climate should actually be very gradually cooling, not warming rapidly as it is. Virtually all of the present warming is attributable to human activity. In other words, yes, people are making it worse.
Burning fossil fuels (coal, oil and natural gas) emit polluting greenhouse gases which are incredible harmful to the planet, causing global warming. Global warming is causing climate change.
