Answer: short answer yes
Yes, by increasing the abundance of greenhouse gases in the atmosphere, human activities are amplifying Earth's natural greenhouse effect. Humans emissions and activities have caused around 100% of the warming observed since 1950, according to the Intergovernmental Panel on Climate Change's (IPCC) fifth assessment report. Global warming is an aspect of climate change, referring to the long-term rise of the planet's temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, deforestation and farming.
