What percentage of CO2 is man made?

I am often asked how carbon dioxide can have an important effect on global climate when its concentration is so small – just 0.041 percent of Earth’s atmosphere. And human activities are responsible for just

32 percent

of that amount.

What is the number 1 cause of global warming?

The evidence is clear: the main cause of climate change is

burning fossil fuels such as oil, gas, and coal

. When burnt, fossil fuels release carbon dioxide into the air, causing the planet to heat up.

What are the top 3 contributors to CO2 emissions?

Notes. Globally, the primary sources of greenhouse gas emissions are

electricity and heat

(31%), agriculture (11%), transportation (15%), forestry (6%) and manufacturing (12%). Energy production of all types accounts for 72 percent of all emissions.

Who is responsible for global warming?

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, and farming

.
