thing they observed was there are several greenhouse gases that were responsible for warming and human emit them in a variety of ways. These gases include water vapor‚ nitrogen‚ methane and carbon dioxide. Most of these gases come from combustion of fossil fuels in cars‚ factories and electricity production. The gas responsible for most warming is carbon dioxide. Other contributors include methane from landfills and agriculture

world more extreme storms‚ more severe droughts‚ deadly heat waves‚ rising sea levels‚ and more acidic oceans‚ which can affect the very base of the food chain. The primary cause of global warming is human activity‚ most significantly the burning of fossil fuels to drive cars‚ generate electricity‚ and operate our homes and businesses. Tropical deforestation‚ also by human hands‚ is another major contributor. According to Union of Concerned Scientists ( 2010) When these forests are burned‚ they release

common? They are all powered by fuel sources. The most popular being fossil fuels. Fossil fuels are dead plant and animal matter that has been compressed and heated over millions of years. They are burned to create heat‚ which in turn creates energy. However‚ with heavy industrialization (agricultural and manufacturing)‚ transportation‚ and personal energy use‚ our world’s fossil fuel supplies are rapidly depleting. Even more‚ fossil fuels pollute our environment. Scientists are on the search for alternative

complicated issue facing world leaders. Warnings from the scientific community are becoming louder‚ as an increasing body of science points to rising dangers from the ongoing buildup of human-related greenhouse gases — produced mainly by the burning of fossil fuels and forests. WHAT IS GLOBAL WARMING? The global surface temperature is an estimate of the global mean surface air temperature. However‚ for changes over time‚ only anomalies... are used‚ most commonly based on the area-weighted global

Advantages of Solar Energy in India Solar energy provides cost effective solutions to energy problems where there is no electricity at all. Some of the advantages of solar energy which makes it all the more suitable for India are as follows: No Pollution : Solar energy is environment friendly. Solar energy is non-polluting‚ clean‚ reliable and renewable source of electricity. It does not pollute the air by releasing harmful gases like carbon dioxide‚ nitrogen oxide and sulphur oxide. Solar energy

| Fossil Fuel: Natural Gas | Renewable resource: Wind Power | Describe this resource | Natural Gas in a Hydrocarbon gas that is naturally occurring. It consists of mostly methane and is used as fuel for some vehicles and heating the home. | Wind power is one of the cleanest sources of electricity. It usually involves a fan that spins‚ and the energy is transported to a generator. | Advantages of this resource (include at least two) | 1. Very abundant underground.2. Is cleaner than most other

Hydro power stations utilise water‚ as a zero cost input energy source against which there is a constant escalation in cost of fossil fuels used in thermal power station‚ thus making the operational cost of thermal power stations ever increasing. Electricity generation from the hydro is always economical because of the following reasons: * Life of Hydro Plants: Life of

Experts gave deadlines to our country’s natural resources. In 2025‚ trees in the forests of our country may possibly be gone. Same in this year‚ we will be suffering from low supply of clean water in the country. We could also suffer in low supply of fossil fuels in 2030. And in 2050‚ there’s no more fishes to eat. I’ve learned about the four main problem that we and the country will be facing in the future. One of the problem in the country is about the marine resources. It is shown in the documentary

help reduce global warming by decreasing the amount of coal that is burned which further allows us to reline on the electric roads. "Everyone has power. No more power shortages‚ no more roaming power outages‚ no more need to burn coal. Less need for fossil fuels and less dependency upon foreign oil and much less pollution (solar roadways)". This proves that it reduces global warming because if we install these electric roads we wouldn’t need to burn as much coal as we do now. You ask why? Well the roads
