None. Humans only account for less than 2% of all CO2 emissions into th atmosphere. The other 98-99% comes from nature itself such as dying plants and animals, Volcanoes, Weather, natural chemical reations and occurances, (such as methane swamps) and even weather. Lightning, for example, creates what is called Ozone, which is an unstable for of Oxygen (the gas we breathe) that is known to be dense enough to block some wavelengths of light (which started the whole "greenhouse effect" hoax). There is nothing humans that humans have done, are doing, or will ever do that can cause "global warming" or "climate change". More CO2 is released everyday in nature than we release in an entire year. So really, looking at a liberal approach, everything that emits CO2 (whether it being a combustion reaction or not) can theoretically cause "global warming". So technically even your farts are "killing the planet". However there isn't enough CO2 released to actually cause "global warming" (we actually have no real proof it is even happening). So really the answer is: there arent any.
Greenhouse gasses are the cause of Global Warming.
Humidity itself does not directly contribute to global warming, but it can impact the greenhouse effect by affecting cloud formation. Higher humidity levels can lead to more cloud cover, which can trap heat in the atmosphere and contribute to global warming.
Yes, volcanoes can contribute to global warming by releasing greenhouse gases and aerosols into the atmosphere.
Tornadoes do not directly contribute to global warming. However, the severe weather patterns that can result from climate change, which is linked to global warming, may increase the frequency and intensity of tornadoes.
This is known as the greenhouse effect. Greenhouse gases, including carbon dioxide, trap heat in Earth's atmosphere, leading to a warming effect. This phenomenon can contribute to global warming and climate change.
They don't help with global warming naturally but the large buildup of greenhouse gases does assist with global warming.
Greenhouse gasses are the cause of Global Warming.
Greenhouse gases cause global warming on earth. This global warming can cause ozone depletion.
No
Methane, carbon dioxide, CFCs (chlorofluorocarbons).
Humidity itself does not directly contribute to global warming, but it can impact the greenhouse effect by affecting cloud formation. Higher humidity levels can lead to more cloud cover, which can trap heat in the atmosphere and contribute to global warming.
Hydroelectricity does not contribute to global warming.
yes
Yes, volcanoes can contribute to global warming by releasing greenhouse gases and aerosols into the atmosphere.
Solar panels do not contribute to global warming. In fact, they help reduce greenhouse gas emissions by generating clean energy from the sun.
exhaust from plane
Yes, refrigerators can contribute to global warming due to the gases they use as refrigerants, such as hydrofluorocarbons (HFCs). If these gases leak into the atmosphere, they can trap heat and contribute to the greenhouse effect. It's important to properly maintain and dispose of refrigerators to minimize their environmental impact.
