Global Warming contributions?

Question

What are some nonliving and living factors that contribute to global warming?

Also, what are some positive and negative human impacts?

Answer 1

Human Impacts:

-propaganda

-increase in general stupidity

-Big government

Answer 2

global warming isn't even real.

Answer 3

C02 emissions from industrialization which leads to methane build up in arctic ice and releases more co2 and other greenhouse gases. Non-living factors include temperature cycles causes by the hotspots on the sun. Negative impacts are global catastrophes and possible human extinction.

Answer 4

The nonliving factors are:

- Changes in Solar Output: the amount of energy radiating from the earth’s sun is not constant.

- Changes in the Earth’s Orbit: Slow variations in the Earth’s orbit around the sun change where and when energy is received on earth.  This affects the amount of energy that is reflected and absorbed.

-  The Greenhouse Effect: When energy from the sun enters the Earth’s atmosphere, about a third of it is reflected back to space.  Of the rest, the atmosphere absorbs some, but most of it is absorbed by the surfaces of the earth.  The Earth emits energy at longer wavelength. Some of this energy escapes to space but some is absorbed again and remitted by clouds and the greenhouse gases such as water vapor, carbon dioxides, methane and nitrous oxide. This helps to warm the surface and the troposphere (lowest layer of the atmosphere), keeping it 33°C warmer than it would be otherwise be.

- Aerosols: these are fine particles and droplets that are small enough to remain suspended in the atmosphere for considerable periods of time.  They both reflect and absorb incoming solar radiation.  Changing the type and quantity of aerosols in the atmosphere affects the amount of solar energy reflected or absorbed.

The living/human factors are:

- Enhancing the Greenhouse Effect: naturally occurring greenhouse gases, as described above, keep the Earth warm enough to support life. However, scientific studies have shown that a variety of human activities release greenhouse gases.  These include the burning of fossil fuels for producing electrical energy, heating and transportation. By increasing their concentrations and by adding new greenhouse gases like CFCs, humankind is capable of raising the average global temperature.

- Land Use Change: As humans replace forests with agricultural lands, or natural vegetation with asphalt or concrete, they substantially alter the way the Earth’s surface reflects sunlight and releases heat. All these changes also affect regional evaporation, runoff and rainfall patterns. Land use and the changes in the way it is used effect the global carbon cycle, reduce the world’s forests and woodlands, expand the cropped land area, and cause tropical deforestation.  As well, there is increased productivity of labor in exploiting land through the application of capital and new technologies. Conversion of land from natural to agricultural use also upsets the balance.

- Atmospheric aerosols: Humans are adding large quantities of fine particles (aerosols) to the atmosphere, both from agriculture and industrial activities. Although most of these aerosols are soon removed by gravity and rainfall, they still affect the radiation balance in the atmosphere. Whether this effect adds to or offsets any warming trend depends on the quantity and nature of the particles as well as the nature of the land or ocean surface below. The regional effects, however, can be significant.

- Burning of Fossil Fuels for Energy: As humanity burns the organic matter from past geologic periods (or the forests of today) to power the engines and economies of modern society, we are re-injecting our fossil carbon legacy into the atmosphere at incredibly accelerated rate.  Carbon dioxide is dumped into the atmosphere at a much faster rate than it can be withdrawn or absorbed by the oceans or living things in the biosphere.  The carbon dioxide buildup is a principal controlling factor of the climate change.

The negative human impacts are the ones i refered as "The living/human factors".

The positive human impacts are not many but there are some such as reducing the CO2 emissions, recycling, planting trees, in general if we make less pollution we are decreasing the impact of Global Warming.

Answer 5

People's imagination, rampant press trying to sell more issues, politicians on a power grab, psudo-scientist who are fixed on their next grant all contribute to global warming

Answer 6

Known non-living factors:  The Sun, Earth's geothermal activity, and Earth's atmosphere

Known living factors:  None

Human impacts, positive or negative:  None

We know the Sun is the energy generating source.  We know our atmosphere insulates the planet from the cold vacuum of space.  We know water is the most abundant greenhouse gas within the atmosphere, with all other greenhouse gases combined making up less than 1% of the atmosphere.  We know the Sun has been more active now than it has been in over 1,000 years.  We know the Earth has been in a warming trend since the last Ice Age.  We know humans are motivated by fear and greed.  All of these facts contribute to the theory of global warming.

Answer 7

The green house gas is not there so how can it cause Global Warming... It is a LIE... propagated by the LEFT and Gore...

Answer 8

Nonliving factors:

The sun

Geothermal activity

Natural warming and cooling cycles

Human Impact:

None

Answer 9

Contributions: your face(more specifically your mouth), your derriere(flatulence), bilderbergs

human impacts: propaganda other wise none

FIGHT THE POWER

Answer 10

Non-living and main - The sun
