Geography help!! PLEASE HELP i have been working on it for 2 hours and i cant get it!!?

Question

every answer is appreciated!

What are sone human activities that are causing the earth to warm in global climate change?

kk i did th rest i just cant get this answer!

Answer 1

Massive usage of chlorine gas, Some of it gets up to the Ozone layer destroys Ozone and allows ultraviolet light in to heat up the Earth.

Massive killing of plants by building roads and houses etc.

Use of fossil fuels that put massive amounts of CO2 into the air.

The killing of animals that stir up the Oceans such as fish and whales who move nutrients in the water that plants need to grow.

Answer 2

Most scientists don't believe human activities have anything to do with global warming.  The earth has gone through these cycles before as can be seen with the melting of the ice ages.

A direct quote about the myths from the below website:

Yet there is no scientific consensus that global warming is a problem or that humans are its cause. Even if current predictions of warming are correct, delaying drastic government actions by up to 25 years will make little difference in global temperature 100 years from now.

Answer 3

buring of fossil fuels to provide us with energy that we use for driving, electricity etc. but when we burn fossil fuels they release greenhouse gases which warm the climate.

Answer 4

Burning fossil fuels for energy, then wasting them. (Gives off CO2 which is a greenhouse gas)

Answer 5

burning fossil fuels...

im kinda' smart @ this stuff

Answer 6

Our energy usage - leaving lights on, driving, not recycling, etc.

Answer 7

Greenhouse gases



Scientific consensus has identified carbon dioxide as the dominant greenhouse gas forcing. (The dominant greenhouse gas overall is water vapor. Water vapor, however, has a very short atmospheric lifetime (about 10 days) and is very nearly in a dynamic equilibrium in the atmosphere, so it is not a forcing gas in the context of global warming.) Methane and nitrous oxide are also major forcing contributors to the greenhouse effect. The Kyoto Protocol lists these together with Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), and Sulphur hexafluoride (SF6), which contribute to climate change primarily by interfering with atmospheric ozone concentrations. The chart at right attributes anthropogenic greenhouse gas emissions to eight main economic sectors, of which the largest contributors are power stations (many of which burn coal or other fossil fuels), industrial processes (among which cement production is a dominant contributor), transportation fuels (generally fossil fuels), and agricultural byproducts (mainly methane from enteric fermentation and nitrous oxide from fertilizer use).

Land use

Climate change is attributed to land use for two main reasons. While 66% of anthropogenic CO2 emissions over the last 250 years have resulted from burning fossil fuels, 33% have resulted from changes in land use, primarily deforestation.Deforestation both reduces the amount of carbon dioxide absorbed by deforested regions and releases greenhouse gases directly, together with aerosols, through biomass burning that frequently accompanies it. A second reason that climate change has been attributed to land use is that the terrestrial albedo is often altered by use, which leads to radiative forcing. This effect is more significant locally than globally.

Livestock and land use

Worldwide, livestock production occupies 70% of all land used for agriculture, or 30% of the ice-free land surface of the Earth.[6] Scientists attribute more than 18% of anthropogenic greenhouse gas emissions to livestock and livestock-related activities such as deforestation and increasingly fuel-intensive farming practices.[6] Specific attributions to the livestock sector include:

9% of global carbon dioxide emissions

35-40% of global methane emissions (chiefly due to enteric fermentation and manure)

64% of global nitrous oxide emissions, chiefly as a result of fertilizer use.
