Frequently Asked Questions and Answers About Global Warming

What is global warming?

The aftermath of the industrial revolution resulting to a tremendous upsurge in the temperature levels globally is what is referred to as the global warming. The upsurge from 1880 is estimated to have elevated by approximately 1.4 degrees Fahrenheit which is equivalent to 0.8 degrees Celsius. This is not to say that the process has come to a halt, the process of global warming is still in motion and an estimation of an upsurge ranging between 0.3 and 0.7 degrees Celsius is estimated to have occurred by 2035 by scientists.

What causes global warming?

The greenhouse gases namely methane and carbon dioxide are responsible for maintaining the warm temperatures on earth hence making it possible for life to exist. If these gases were absent the temperature of the earth would be 0 degrees Fahrenheit as opposed to the current temperature of 58.3 degrees Fahrenheit. Methane and carbon are responsible for trapping the energy or heat emitted into the atmosphere by the sun. When activities such as fossil fuel burning occurs the atmosphere is saturated with extra carbon dioxide. Fossil fuels such as oil, coal and natural gas are often used by human beings in the household, industries and as a source of fuel for automobiles. The methane levels are elevated in the atmosphere by human activities such as livestock breeding. When the levels of the greenhouse gases increase in the atmosphere they result to more heat from the sun being retained in the atmosphere resulting to an increase in the temperatures globally caused by the human activities. The numerous researches carried out by scientists have illustrated that the main cause of global warming, about 97%, is due to the human activities.

What is climate change? Is it different than global warming?

The term climate change is used to describe the impact of the global warming resulting due to manmade actions in relation to other major changes occurring in the atmosphere such as glaciers melting, storms, droughts, ice sheets, coral reefs, rising sea levels, acidification of oceans, seas becoming warm and marine food chain disruption. The term climate change is used to refer to the fluctuations in the earth’s natural climate especially the fluctuation between the warm and cold seasons. There are times when the terms global warming and climate change are used interchangeably though they are not totally identical.

It is estimated that the rate of global warming has tremendously increased over the period of the last five decades more than over eight hundred years ago. This is due to the rampant use of fossil fuels that is universally widespread. The absence of volcano activities or increase in the intensity of the sun are supposed to have helped the earth in cooling off a little bit but the fossil fuels are a catalyst to achieving to opposite result. The global warming impacts are already evident and being experienced globally with the frequent occurrences in harsh storms, droughts and floods. Crops are constantly being destroyed and shortages in water are being experienced as a result of changes in the weather patterns. Climate change poses the greatest hazard to the health of the society.

What does global warming have to do with severe weather, like droughts and hurricanes?

When global warming occurs it escalates the seriousness as well as the chances of harsh weather conditions such as droughts, storms, heat waves and wildfires occurring. The atmosphere in warm climates allows it to trap and release more water which results to the dry areas becoming drier and the wet areas getting more wet. The elevated levels of precipitation are ideal for agricultural practices but when it elevates to become storms the plants, infrastructure, lives and valuable properties are damaged. Hurricanes usually happen as a result of the oceans becoming warm and global warming seems to act as a catalyst which can explain the widespread regular occurrences of storms globally. Scientists are yet to discover the one concrete weather that is connected to global warming but they are almost certain that the extreme rises in temperature are the aftermath of global warming.

If global warming is real, why is it so cold and snowy in winter?

There are still many people who do not believe that global warming exists since winter still occurs. Global warming is not an instant action but a consequence that occurs over a period of time. Global warming might result to a winter being warm or it being extremely cold. It is speculated that as time progresses and the global warming rate increases the winters will be experienced for a limited span of time.

What does global warming have to do with rising sea levels?

There are two ways in which global warming can result in the sea levels rising. The temperatures in the Antarctic and arctic regions increase with double the rate the rest of world increases. This results to the winters being warmer and the summers being hotter which makes the ice sheets and glaciers to melt slowly.
