What Gases Contribute To The Greenhouse Effect – Greenhouse gases (GHG) are important elements in our ecosystem. They “capture” the sun’s heat in the Earth’s atmosphere, heat that would otherwise escape into space, and radiate it back toward the Earth’s surface: a phenomenon known as the “greenhouse effect.” One of the better known greenhouse gases is CO

The phenomenon of the ‘greenhouse effect’ is important because it keeps the temperature of the planet in an acceptable range for life as we know it. However, excessive emissions of greenhouse gases cause negative effects on our planet and our economy. The concentration of greenhouse gases in the atmosphere has increased significantly since the industrial revolution, and scientists[1] have strong evidence that this increase is the result of human activity. Growth in greenhouse gas emissions is associated with rising temperatures on our planet, resulting in severe weather and a number of other impacts generally referred to as “global warming” or “global warming” [2].

What Gases Contribute To The Greenhouse Effect

Global warming has a significant impact on agriculture. The Intergovernmental Panel on Climate Change (IPCC), the United Nations’ body for assessing the science related to climate change, has issued a special report on climate change and soil[3].

Energy And Global Warming Impacts Of Cfc Alternative Technologies

Warming over land has occurred at a faster rate than the global average and this has had a visible impact on the land system. The average temperature over land for the period 2006-2015 was 1.53°C higher than for the period 1850-1900, i0. 66°C higher than the equivalent global mean temperature change. These higher temperatures (with changing precipitation patterns) changed the beginning and end of growing seasons, contributed

At the same time that global warming affects agriculture, like most economic sectors, agriculture also produces greenhouse gases that contribute to this phenomenon. Emissions from agriculture are mainly related to land use change[4] and agricultural practices.

Figure 2 shows the contribution of agriculture to total greenhouse gas emissions (%) in Europe[5], while figure 3 shows greenhouse gas emissions in the world by sector.

Land-use change is the process by which human activities change the use of a landscape, such as the transformation of an indigenous forest area into grassland or wetlands in an urban area.

In this sense, agriculture represents a push towards land conversion as it expands into new frontiers and converts forests, natural grasslands and other natural environments into cropland. This especially applies to less developed countries. The IPCC reports that during the 1990s deforestation in the tropics was a major contributor to greenhouse gas (GHG) emissions.

Agricultural soil management, cultivation practices, livestock, rice production and biomass burning are the most relevant sources of greenhouse gas emissions in agriculture-related activities[6]. From a crop production perspective, key greenhouse gas emissions are associated with:

The cultivation of rice is one of the most relevant crops in terms of emissions, especially considering its importance as food, and thus the amount produced. In the anaerobic conditions of the submerged soil of flooded rice fields, methane is produced and a large part escapes from the soil into the atmosphere.

Figure 4[7] shows the relative contribution of different activities related to agriculture, including animal husbandry, which is not discussed in this article.

Greenhouse Gas Emissions By Country And Sector (infographic)

ProTerra encourages organizations to minimize the use of non-renewable energy and adopt sustainable agricultural production practices to reduce greenhouse gas emissions through a series of requirements, many of which are critical and therefore must be met for certification to the ProTerra standard.

In particular, ProTerra has certification criteria related to the reduction or compensation of greenhouse gas emissions or energy management and also defines a set of indicators related to agricultural practices, such as reducing the use of chemical fertilizers, banning the burning of agricultural residues, encouraging the use of cover crops and crop rotation .

To minimize land-use changes associated with agricultural activities, ProTerra has defined a cut-off date[8] for land conversion, especially primary forests (such as tropical rain forests), riparian vegetation (those adjacent to water bodies), swamps, marshes, steep slopes and areas defined by the Resource Network of High Conservation Value[9] (HCV).

The ProTerra Standard also includes a set of indicators related to the maintenance and enrichment of biodiversity. Forests, through the growth of trees and the increase of carbon in the soil, contain a large part of the carbon stored on land. Forests represent a significant global carbon store[10]

How Do Greenhouse Gases Contribute To Global Warming?

The ProTerra Foundation believes that agriculture has an important role to play in reducing greenhouse gas emissions and that this is key to sustainably producing food.

Total emissions in 2018 = 6,677 million metric tons of CO2 equivalent. Percentages may not sum to 100% due to independent rounding. Larger image to save or print Gases that trap heat in the atmosphere are called greenhouse gases. This section provides information on emissions and removals of major greenhouse gases to and from the atmosphere.

The Enhanced Greenhouse Effect

A million metric tons equals about 2.2 billion pounds, or 1 trillion grams. In comparison, a small car will probably weigh a little more than 1 metric ton. So a million metric tons is about the same mass as 1 million small cars!

The US inventory uses metric units for consistency and comparability with other countries. For reference, the metric ton is slightly larger (about 10%) than the US “short” ton.

Equivalently, its emissions are multiplied by the global warming potential (GWP) of the gas. GWP takes into account the fact that many gases are more effective at warming the Earth than CO

The GWP values ​​that appear on the emissions web pages reflect the values ​​used in the US inventory, which are drawn from the IPCC’s Fourth Assessment Report (AR4). For further discussion of GWP and estimation of greenhouse gas emissions using the updated GWP, see Appendix 6 of the US Inventory and the IPCC Discussion of GWP (PDF) (106 pages, 7.7 MB). Exit

Greenhouse Effect 101

Concentration or abundance is the amount of a certain gas in the air. Higher emissions of greenhouse gases lead to higher concentrations in the atmosphere. Greenhouse gas concentrations are measured in parts per million, parts per billion, and even parts per trillion. One part per million is equivalent to one drop of water diluted in about 13 gallons of liquid (about the fuel tank of a compact car). To learn more about rising concentrations of greenhouse gases in the atmosphere, visit the Climate Change Indicators: Atmospheric Concentrations of Greenhouse Gases page.

Each of these gases can remain in the atmosphere for different periods of time, ranging from a few years to thousands of years. All of these gases remain in the atmosphere long enough to mix well, meaning that the amount measured in the atmosphere is roughly the same worldwide, regardless of the source of the emission.

Some gases are more effective than others in warming the planet and “thickening the Earth’s mantle”. For each greenhouse gas, a global warming potential (GWP) is calculated, which reflects how long it stays in the atmosphere on average and how strongly it absorbs energy. Gases with a higher GWP absorb more energy, per pound, than gases with a lower GWP and thus contribute more to global warming.

Accounted for about 81.3 percent of all US greenhouse gas emissions from human activities. Carbon dioxide is naturally present in the atmosphere as part of the Earth’s carbon cycle (the natural cycling of carbon between the atmosphere, oceans, soil, plants and animals). Human activities change the carbon cycle – both by adding more CO

Emissions come from a variety of natural sources, man-made emissions are responsible for the increase that has occurred in the atmosphere since the industrial revolution.
