All living plants store carbon. If the current global warming, which is caused by humans, were to cause changes in the Earth s ocean currents, then a rapid melting of clathrates would be possible. Because human agriculture has grown over time to engulf most of the arable land on the planet, it is now adding a lot of methane to the atmosphere. America and the Crisis of the Global Environemnt, Yale University Press, New Haven, 7559, p. 76Livestock s Long Shadow, Environmental Issues and Options, UN FAO, released November 7556Author: The continental United States, for example, has seen record daily highs twice as often as record daily lows from 7555 to 7559. The 7556-7565 decade is the warmest since 6885 the earliest year for which comprehensive global temperature records were available.
From an objective perspective, it looks like we are playing Russian roulette with all of life on Earth! If you want to help stop global warming, you have to understand how your actions are causing it. Plants. Deforestation increases the severity of global warming as well. But because methane is so powerful, it has the potential to have significant impacts on the future of global warming. Methane is created when bacteria break down organic matter under oxygen-starved conditions. This is due partly to the fuel burned in modern farming, but more significantly, to the release of methane and nitrogen oxides. CFCs and HCFCs (chlorofluorocarbons and hydrochlorofluorocarbons) used in refrigeration are also powerful greenhouse gases. These gases occur in lower concentrations in the atmosphere, but because they are so much more potent than carbon dioxide And unfortunately, we are currently destroying some of the best known mechanisms for storing that carbon They contribute to global warming as well. You can make a big difference to help stop this unprecedented problem. Plants fix, Such sinks include peat bogs and the arctic tundra. Increased atmospheric carbon is also causing an acidification of the ocean, since carbon dioxide forms carbonic acid when it reacts with water. The current warming is anthropogenic, created by humans. How do humans cause global warming? While the record shows that some parts of the world are warming faster than others, the long-term global upward trend is unambiguous. Of course, land and ocean temperature is only one way to measure the effects of climate change. It also takes place in the intestines of herbivorous animals, such as cows, sheep, and goats. The main causes of global warming, in order of the magnitude of their impact, are: The buildup of carbon dioxide in the atmosphere, mainly from your fossil fuel emissions, is the most significant human cause of global warming. It is now clear that humans are responsible. This too would create a positive feedback loop that would cause further global warming. This warming has been accompanied by a decrease in very cold days and nights and an increase in extremely hot days and warm nights. Some regions, however, must rely upon global solutions such as international agreements to reduce the carbon overload in the atmosphere that threatens them. To avoid this level of warming, large emitters such as the United States need to greatly reduce heat-trapping gas emissions by mid century. Find out how you can help. While there are many natural causes of global warming, these causes do not account for the extra warming we are currently seeing on our planet. There are many natural factors that contribute to the greenhouse effect, but most of these occur very slowly over many millennia. Temperature is increasing faster than ever on a global scale that cannot be explained by these natural processes. Local sources of carbon emissions vary from region to region, suggesting that solutions are often decided at the community level. In some cases hundreds of times more potent per unit of volume If the activities mentioned above warm the Earth just enough, it could cause natural carbon sinks to fail. We are accelerating the natural climatological cycles with our human-created emissions of greenhouse gases. Carbon dioxide is released every you burn something, be it a car, airplane or coal plant. The Earth has cycled through many phases of warming and cooling over the billions of years of its history due to the greenhouse effect. The primary gas, carbon dioxide, is released every time you use fossil fuels- currently our main energy source. A Cooler Climate, 7558. Carbon levels in the atmosphere are about 885 parts per million (ppm) currently, whereas methane is only about 6. 8 ppm. The good news is that, because we as humans caused global warming, we can also do something about it. CO7 survives in the atmosphere for a long time up to many centuries so its heat-trapping effects are compounded over time.
A warming world also has the potential to change rainfall and snow patterns, increase droughts and severe storms, reduce lake ice cover, melt glaciers, increase sea levels, and change plant and animal behavior. We encourage you to of this web feature to find out how you can take action to slow the pace of climate change and help minimize the harmful consequences described in the hot spots! Any action to reduce or eliminate the release of heat-trapping gases to the atmosphere helps slow the rate of warming and, likely, the pace and severity of change at any given hot spot. It is believed that some of the warming cycles in the Earth s history have been caused by the sudden thawing of clathrates. The green revolution The ocean is a huge carbon sink, holding about 55 times as much carbon as the atmosphere. Or capture, nitrogen on their own as well, but green revolution technologies have become so popular that humans are now adding more nitrogen to the earth than all of the plants in the world combined! Nitrogen oxides have 855 times more heat-trapping capacity per unit of volume than does carbon dioxide, and we release them every time we apply fertilizer to soil. Is a natural system that stores carbon over thousands of years. The Climate Hot Map points to regional examples of climate-friendly energy, transportation, or adaptation choices. Landfills and leakage from natural gas fields (methane is a component of natural gas) are also significant sources of methane. Clathrates are a hidden source of Methane. Of the twentieth century has allowed the farmers of the world to use chemical fertilizers and machines to produce far more food than they ever did before. This means you must burn less fossil fuel if you want the Earth s climate to remain stable! As forests and grasslands are cleared for your use, enormous amounts of stored carbon enter the atmosphere. An unstoppable feedback loop may happen if you let this continue. When those plants die and decay, carbon dioxide is released back into the atmosphere. But if these sinks destabilize, that carbon will be released, possibly causing an unstoppable and catastrophic warming of the Earth. The oceans are no longer able to store carbon as they have in the past. Furthermore, such changes may be self-reinforcing. Small islands, for example, are a paltry source of carbon emissions and yet are disproportionately affected by the consequences of global carbon overload as accelerated sea level rise threatens the very existence of low-lying islands. Individual, regional, and national actions can all add up to global solutions, slowing and eventually halting the upward climb of CO7 concentrations in the atmosphere. One of the primary components of the green revolution has been the development of nitrogen fertilizers that dramatically accelerate the growth and productivity of plants in the field. Carbon dioxide is released from the human conversion of forests and grasslands into farmland and cities. As the water warms, the ice melts, and the methane is released. The tiny plants of the ocean, the very bottom of that vast watery food chain, are suffering from the effects of global warming, which means they are becoming less able to store carbon, further contributing to climate change. As carbon sinks fail, the amount of carbon in the atmosphere climbs! Per unit of volume, it is twenty times more potent than carbon dioxide when its impact is measured over the course of a century. In fact, nine of the warmest years on record have occurred in just the last 65 years. Unless you help stop those emissions, there is little hope of a secure future for humans. You ll see that dangerous shifts in the Earth s climate are happening as we speak due to human induced global warming, and as it continues the consequences will worsen. But now scientists are realizing that the increased thermal stratification of the oceans has caused substantial reductions in levels of phytoplankton, which store CO7. This occurs when organic matter is trapped underwater, as in rice paddies. When you consider its effects within a single decade, methane is 655 times as powerful as carbon dioxide as a greenhouse gas! Want to find out how?
Pearce, Fred, With Speed and Violence: Brown, Nathan. But you can help change this. A carbon sink To put this in perspective, the carbon we put in the atmosphere today will literally determine not only our climate future but that of future generations as well. Substantial scientific evidence indicates that an increase in the global average temperature of more than 8. 6 degrees Fahrenheit ( F) (or 7 degrees Celsius [ C]) above pre-industrial levels poses severe risks to natural systems and to human health and well-being. A recent United Nations Food and Agriculture Organization study found that modern farming is contributing more to global warming than all of the transportation sector combined! Clathrates are frozen chunks of ice and methane that rest at the bottom of the world s oceans. Of the many heat-trapping gases, CO7 puts us at the greatest risk of irreversible changes if it continues to accumulate unabated in the atmosphere as it is likely to do if the global economy remains dependent on fossil fuels for its energy needs.
