Date modified:. A few greenhouse gases are water vapor, carbon dioxide, and methane. The earth's climate is naturally variable on all time scales. It is this human-induced enhancement of the greenhouse effect that is of concern because ongoing emissions of greenhouse gases have the potential to warm the planet to levels that have never been experienced in the history of human civilization.
Changes in land use also play a role. In addition to other environmental impacts, these activities change the land surface and emit various substances to the atmosphere. Deforestation and soil degradation add carbon dioxide to the atmosphere, while forest regrowth takes it out of the atmosphere. Every one of us is feeling very clearly from the short-term changes in the seasonal patterns of temperature, drought, rainfall without season, changing weather patterns, etc.
The fact that there have been natural cycles of climate change since earth's formation, in past and recent centuries humans have influenced global climate change through the emission of greenhouse gases. A greenhouse gas absorbs thermal radiation emitted by the Earth 's surface. Human activity is the main cause of climate change. The cooling from sulphate aerosols in the atmosphere has, however, offset some of the warming from other substances. Greenhouse Gas Emissions. Some, like certain aerosols, can produce cooling.
Unfortunately, not everyone concurs to this reasoning. Volcanic eruptions are episodic and have relatively short-term effects on climate. To make matters worse, this problem is a manifestation of human activities. The major question needs to be posed yet again: Is there actual statistical evidence to verify that climate change is not a short term observed trend in global climate and an imminent danger Some believe that our kind has become blind to what may or may not be happening to the planet, and that is climate change. Burning fossil fuels produces carbon dioxide, a greenhouse gas.
Emissions of carbon dioxide, which account for about three-fourths of total emissions, increased by 42 percent over this period. EPA has now verified three years of data and made them publicly available. Individuals are beginning to realize the importance of greenhouse gas emissions and keeping our environment clean. Such records must be analysed carefully, to identify the influence of any non-climate factors such as changes in observing site or method, or encroaching urban development.
I believe that humans are play the main role in climate change. From the cars driven to the.
Such records must be analysed carefully, to identify the influence of any non-climate factors such as changes in observing site or method, or encroaching urban development.
The changes have resulted from a strengthening of highs to the north of New Zealand, squeezing stronger westerly winds over southern and central New Zealand. Most every environmental problem can traced to climate change. Greenhouse Gas Emissions indicator come from the national inventory.
That is, the warming we have experienced to date would have been even larger had it not been for elevated levels of sulphate aerosols in the atmosphere. Atmospheric Concentrations of Greenhouse Gases. Since the beginning of the Industrial Revolution, these human influences on the climate system have increased substantially. Greenhouse Gas Emissions indicator come from the national inventory. Carbon Monoxide release is a result of burning fossil fuels with an insufficient amount of oxygen that causes the formation of carbon monoxide that pollutes our environment.
Changes in solar irradiance have contributed to climate trends over the past century but since the Industrial Revolution, the effect of additions of greenhouse gases to the atmosphere has been over 50 times that of changes in the Sun's output. This student agrees with many of the points brought out in the article about the effects of fossil fuel energy and the harmful emissions produced. Climate change is the long term variations in the weather patterns. A greenhouse gas absorbs thermal radiation emitted by the Earth 's surface. Greenhouse Gas Emissions. You will not receive a reply.
I believe that humans are play the main role in climate change. The effects of CO2, methane, nitrous oxide, and fluorinated gases, a part of the greenhouse effect, are destroying the environment. These times can be anywhere from decades to millions of years. This is what we call the greenhouse effect which is the main reason we have global warming. Every one of us is feeling very clearly from the short-term changes in the seasonal patterns of temperature, drought, rainfall without season, changing weather patterns, etc.
