Answer 1

One of the most current and widely discussed factor which could lead to the ultimate end of existence of Earth and man is global warming and its devastating effects. Scientists have asked how fast the Earth is heating up, and how the warming effects on Earth may effect crops and climatic conditions. Several current trends clearly demonstrate that global warming is directly impacting on; rising sea levels, the melting of icecaps, and significant worldwide climatic changes..


Global warming has great effect on crops and weather conditions around the world. The northern hemisphere contains more land area than the southern hemisphere, and conversely, a lower percentage of the world's oceans. Since oceans absorb more heat than land areas, it is not surprising that most climate models predict faster heating over the northern hemisphere than the global average. In addition, models predict faster temperature increases at higher latitudes. If global warming trends continue, high temperatures everywhere in the US may reduce US agricultural productivity. Northern continental areas are projected to have drier summer soils, due in part to earlier snow melts in the spring, and hotter, more cloudless summers, causing extensive evaporation of ground moisture. In addition, if the inland areas of the northern hemisphere are expected to receive less moisture, then, lake and river levels will be lower. Some reports predict the level of the Great Lakes will drop between 2 and 8 feet. River flows in the western US may be very vulnerable to increase temperatures expected as result of the greenhouse effect.

When many people think of global warming, their first concern is the possible rise of sea levels. With a large number of the world's cities in coastal areas, this is a significant problem. There are two major causes of rising sea levels. First, extra water is produced when ice melts. Secondly, the natural expansion of sea water as it becomes warmer. The range of sea ice around both poles continues to shrink, as it melts. Even with the level of greenhouse gases present today, the earth may warm enough in the next 50 years or so to completely melt the sea ice located on the poles.

Damage from rising seas is very diverse. Buildings and roads close to the water could be flooded and they could suffer damage from hurricanes and tropical storms. "There are good physical reasons to suggest that more intense storms (hurricanes) could result from global warming." Warmer oceans cause more intense storms. Experts believe that global warming could increase the intensity of hurricanes by over 50 percent. Hurricane Andrew's devastation in 1992 set new records. According to the National Hurricane Center in Miami, the 1990 season was the most active year on their records for combined Atlantic and Pacific hurricanes. Damage caused by future hurricanes to populated areas will be more severe since higher sea levels are predicted for the next century. In addition, as the sea rises, beach erosion takes place, particularly on steep banks. Wetlands are lost as sea levels rise. Another serious problem is the threat of salt water intruding into underground fresh water reserves in coastal areas.

There is a clear link between the problems of global warming and overpopulation, as increases in CO2 levels follows growth in population. Presently, we have too many people on Earth, who are using technologies that are destructive for the Earth. We cannot continue to grow, and make use of limited natural resources

Answer 2

I live within walking distance of the Pacific Ocean, and I have lived here when the alarmists/leftists were proclaiming global cooling. Over 30 years ago they started chanting global warming and predicted that where I live would have a serious rise in ocean levels, flooding lowlands, that would happen within twenty year or less. That was 25 years ago and I'm still waiting. Nothing has changed, not the ocean level, not the water temperature. The state climatologist, George Taylor, exposed the scam, and he is a real scientist, not a politician. The state governor read Taylor's report, and fired him, or tried to. Taylor wasn't politically correct. Also, I studied Earth Science in college as a minor. Also, I'm not new to science; I've spent my live working in Science and Technology. All my friends are scientists or technologists. So, don't repeat Al Gore's lies to me. This climate change hoax runs along leftist political lines, and it is fed by liars and morons. Believe it!

Answer 3

1. Extreme weather changes and climatic conditions.
2. Increased risk of natural calamities like earthquake, typhoons, volcanic eruptions, drifting of ocean boundaries and landslides.

Answer 4

We all should be concerned, and not just about the human environment, but the environment for all species - period.

Answer 5

growing seasons will get longer in many areas. Infact, they already have
