what is the relationship between population increases and the greenhouse effect?

More people means more demand for oil, gas, coal and other fuels mined or drilled from below the Earth's surface that, when burned, spew enough carbon dioxide (CO2) into the atmosphere to trap warm air inside like a greenhouse.

Oceans absorb most of the heat produced from greenhouse gas build up, and temperature is only projected to increase. A September 2014 study suggested that increased water temperature might cut plankton populations by messing with natural cycles of nitrogen, carbon and phosphorus.

Simultaneously, these populations encounter limitations to that potential. Some factors affecting human population growth (and other organisms' population growth) include predation, disease, scarcity of vital resources, natural disasters and an inimical environment.

Greenhouse effect, a warming of Earth's surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air. Of those gases, known as greenhouse gases, water vapour has the largest effect.

The relationships between human population, economic development, and the natural environment are complex. ... Furthermore, poverty and lack of economic opportunities stimulate faster population growth and increase incentives for environmental degradation by encouraging exploitation of marginal resources.

Global warming is the increase in earth's average surface temperature due to rising levels of greenhouse gases. But climate change is a long term change in the earth's climate or of a region on earth.

Some disadvantages of the greenhouse effect are quite evident: Global warming: As mentioned previously, the increasing amount of greenhouse gases are causing a gradual rise in the earth's temperature. As a result, the ice in the Polar Regions has started melting and resulting in massive climate changes.

Climate change is a major threat to the health of our planet. Air pollution is closely linked but they are usually treated as separate problems. Rising levels of C02 and other air-polluting gases increase the greenhouse effect, which in turn raises temperatures and affects global weather patterns.

Carbon dioxide controls the amount of water vapor in the atmosphere and thus the size of the greenhouse effect. ... This means that Earth's temperature will increase at least another 0.6 degrees Celsius (1 degree Fahrenheit) because of carbon dioxide already in the atmosphere.

Population growth is the increase per annum. The population change is the difference in no. ... The population change is the result of the difference between the births and deaths in a year, plus the migration from one part of the country to the other.

Kate M. The greenhouse effect is how heat is retained by the atmosphere due to greenhouse gases whereas global warming is the increase in average annual temperatures across the globe.

How is the hydrosphere changing? Human contributions to greenhouse gases in the atmosphere are warming the earth's surface - a process which is projected to increase evaporation of surface water and accelerate the hydrologic cycle. In turn, a warmer atmosphere can hold more water vapor.

So while carbon dioxide contributes less to the overall greenhouse effect than water vapor, scientists have found that carbon dioxide is the gas that sets the temperature. Carbon dioxide controls the amount of water vapor in the atmosphere and thus the size of the greenhouse effect.

Greenhouse effect. The greenhouse effect is a natural process that warms the Earth's surface. ... Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs). The absorbed energy warms the atmosphere and the surface of the Earth.

Human Population Growth and Climate Change. The largest single threat to the ecology and biodiversity of the planet in the decades to come will be global climate disruption due to the buildup of human-generated greenhouse gases in the atmosphere.

The 'greenhouse effect' is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space. ... The gases that contribute to the greenhouse effect include water vapor, carbon dioxide (CO2), methane, nitrous oxides, and chlorofluorocarbons (CFCs).
