Global Warming

Global warming seems to be a problem, and the facts show that the temperatures are rising every year since the records were first kept sometime in the middle of the nineteenth century.  The problem seems to be getting worse every year.  Glaciers seem to be melting more rapidly, and the snow seems to be less every year.  There also seems to be a rise in the level of the sea.  This is particularly frightening because some of the populated land could one day become completely submerged.  Many scientists now believe that these changes in the world are the result of human activity.  

Many Groups Organize Measures Against Global Warming

Although there is much evidence that global warming is the result of human activity, this evidence is not completely accepted by all of the experts.  The evidence does not have to be positive in order to take positive steps against global warming.  There are many steps to take against global warming.  First of all, people can work to reduce the use of fossil fuels including gasoline in their cars.  People can join a carpool so they are not driving alone in their car.  There are now fuel efficient cars that conserve on the fuel used to get any distance.  More people should try to drive these cars that use less fuel.  The companies that manufacture cars should concentrate on making cars that are more fuel efficient.  

Nothing New, You May Argue

You might argue that the greenhouse effect has been with mankind for more than four billion years and there has not been anything to worry about this far. The trouble is that the recent effects of global warming are a bit different because some of the activities that we humans are pursuing as well as certain practices are changing this as yet benign change in climatic conditions.

We have certainly been experiencing the effects of global warming for the past few years most noticeably in changes to climatic conditions. The circulation of the oceans is changing, the planet’s orbit is affected and there is also a change in the sun’s intensity. This is reason to consider what the ill-effects of global warming are, and do something serious to prevent, alleviate as well as reduce its adverse effects on humankind. There have been drastic changes to the globe and dire consequences will not spare humans as well as the millions of other species that are dependent on the earth for their very survival.

With glaciers melting and causing the sea levels to rise, we can see the perfect example of the effects of global warming in the rising sea levels. Though we cannot readily see or perceive these effects of global warming, they are still serious and may cause more land to go under the waters of the seas if we are not careful. This can be seen in the example when just a 0.3 meter rise in sea level will cause the swallowing up of fifteen meters of a beach. It certainly is reason to sit up and take notice before it gets too late.

Other effects of global warming are felt in the effect it has on agricultural practices that are dependent wholly on glaciers melting in a regular manner. There are a number of countries in the world that depend on melting of snows from mountains for irrigation of their plants and in generating electricity. If the melting occurs in periods of bad times, it would throw out of gear the planting as well as harvesting periods thus endangering the economy of these countries on both local as well as national levels.

Global Warming and Climate Change Introduction

The climate is changing drastically, regardless of what skeptics say, there is literal proof that goes to show that the Earth’s surface temperature has increased drastically, even in the past decade alone, as there is now overwhelming scientific consensus that global warming is in fact happening, and not only that but also that it is human-induced.

With global warming and climate change on the increase, and with species and their habitats on the decease, the chances for ecosystems to be able to adapt naturally are diminishing, and many are agreed on the fact that the issue of global warming and climate change just may be one of the greatest threats that is facing the planet.

The Impacts of Global Warming

It is believed that global warming will have incredible impact on the world overall, both on the environment and on society in general, as higher temperatures will cause a melting of ice in Greenland and Antarctica, and this will result in accelerating the rise of the sea level. As well, the speed at which global warming is expected to occur in the 21st century is faster than most plant and animal species will be able to cope with, thus resulting in causing many to become extinct, and quickly at that.

Global warming is also expected to affect human health, as there will most likely be more heart-related illnesses in hot summers, and increased breathing problems as higher temperatures increase air pollution in cities, thus reducing air quality greatly. Also, more extreme weather, for example storms, floods and droughts will have severe impacts on the environment and on society.

Preparing

Extreme Of Temperatures Where Such Extremes Are Not Normal

Global warming has also caused there to be extremes of temperature in places that are not known to have extreme temperatures, and there ahs been precipitation and the cloud cover has also been adversely affected. Some of the reasons why the Earth is experiencing global warming are natural such as the levels of CO2, which because of human activities over the past five decades, has seen a significant rise along with other household gases.

The amount of CO2 in the atmosphere along with greenhouse gases is making the Earth’s surface heat up, which is not good for mankind. In fact, the average surface temperature of the Earth has risen by about one degree Fahrenheit over the past ten decades. This has led to a decrease in snow cover as well as ice extent and there has also been a ten to twenty centimeter rise in sea levels in the same period.

There are also areas of concern where global warming has failed to affect the climate on the Earth such as the oceans of the Southern Hemisphere as well as some parts of the Antarctica, which have not really warmed up in recent times. There have also not been any real trends in the Antarctic sea-ice trends, and nor have we witnessed any real trends of global change in the tropical as well as extra-tropical regions as far as intensity of storms and their frequency is concerned. Also, one has not noticed any systematic change in tornado frequencies, thunder days as well as hail events.
