1. Introduction
Look closely and you will see the effects of climate change.
Scientists have documented climate induced changes in some 100 physical and 450 biological processes. In the Russian Arctic, higher temperatures are melting the permafrost, causing the foundations of five story apartment buildings to slump. Worldwide, the rain, when it falls, is often more intense. Floods and storms are more severe and heat waves are becoming more extreme. Rivers freeze later in the winter and melt earlier. Trees flower earlier in spring, insects emerge faster and birds lay eggs sooner. Glaciers are melting. The global mean sea level is rising.
Even if we reduce our greenhouse gas emissions dramatically today, these trends will continue for decades or centuries to come.
The rate of climate change expected over the next 100 years is unprecedented in human history. Throughout geologic time the average global temperature has usually varied by 5° Celsius over intervals of millions of years. Now scientists believe that the temperature of the Earth’s surface – which has already risen by 0.6°C since the late1800s – is likely to increase by another 1.4 to 5.8°Cduring the course of the 21st century.
Such an unusually rapid rate of change would affect fundamental Earth systems upon which our very lives depend – including ocean circulation and the hydrological, carbon and

    It is becoming more and more evident that global warming is rapidly taking a toll on our earth. The effects can clearly be seen through increases in global average air and ocean temperatures, widespread melting of snow and ice caps, and rising global average sea level. According to the Environmental Protection Agency, Earth’s average temperature has risen by 1.4 degrees Fahrenheit over the past century and will rise another two degrees (at the least) in the coming century. This temperature increase is primarily caused by the greenhouse effect which is caused by increasing concentrations of greenhouse gases in the atmosphere. Such greenhouse gasses include water vapor, carbon dioxide, methane, and nitrous oxide (Climate Change 2007, 3).…

    Global climate change has been a subject of much discussion for some time now. The earth has naturally gone through heating and cooling phases in its lifetime. Most scientists agree that these changes aren’t solely the product of humans, but that the time required for natural climate change has been decreased due to humans. This has led to new problems for the earth and all of its inhabitants. According to research the earth is warming at an average of 1.2-1.4° F every 100 years (epa.gov).…

    Therefore we can say that if we don’t start solving this problem with a quick and an effective solution, we are going to face a major catastrophe. Because of global warming temperatures are rising and the most striking evidence of global warming is a data that shoes the rapid and massive increase of temperatures in the past century. The temperatures on Earth started to rise more and more when metal industries started to develop and expand a lot, and also when many big forests were burned and destroyed. The ten warmest years that happened on planet Earth, occurred during 1997-2008, according to NASA’s Goddard Institute for Space Studies. With the help of the modern technology and science, many world known scientists from all over the world were able to calculate that, the rising temperatures observed from 1978 have nothing to do with the rising temperature of the sun at that time. They were able to see that the energy reaching the Earth from the Sun is not causing the rise in the temperatures and that Earth’s warming was not due to changes in the Sun. Another problem that is caused by Global Warming is the rising sea levels. The sea level has increased over 8 to 9 inches, and the increasing rate is not stopping. Authors of the IPCC reported…

    Ice caps with high albedo are melting faster than before while the ocean (93% of global warming) is absorbing more heat than before. According to Surface Temperature Analysis from NASA, global temperature has warmed at the highest rate at 1.12 degrees Fahrenheit anomaly in 2010 and is expected to get worse. The 1990s was the hottest decade on record but the 2000s were even hotter according to the NRC. The UK’s Met Office (National Weather Service) predicted that if we allowed the earth’s temperature to increase to 4 degrees Celsius then the impact will be catastrophic. A 2-foot rise in the global sea level is expected by the year 2100 while oceans become more acidic as carbon dioxide emissions in the atmosphere dissolve in the ocean. This acidification will harm the ecosystem (about 60% of ocean life depends on coral reefs) that is sensitive to the pH of the ocean water. The average land temperature will be 5.5 degrees above pre-industrial levels, agricultural yields are expected to decrease for all major cereal crops in all major regions of production, and half of all Himalayan glaciers will be significantly reduced by 2050, leading to 23% of the Chinese population deprived of the vital dry season glacial melt water source.…

    The idea of climate change, for many, is an opinionated subject with much discussion of whether it is a real issue or just a natural phenomenon. However in recent years it is clear to see that trends in the Earth’s climate and surface temperature has spiked to levels never seen before. Despite all the evidence of the high levels of greenhouses gases and the rise in temperature, many still believe that there is no connection between the two, and that the Earth is just going through its natural cycle.…

    This is not very encouraging information, especially when, in the same report, according to the World Bank, global temperatures may rise as much as 2 degrees Celsius (above the ‘pre-industrial era levels’), over the next 30 years or so, due to increasing concentrations of greenhouse gases in the atmosphere.…

    In the past 100 years, the temperature of our Earth has increased by about 4.5 degrees (Guggenheim). This may not seem like a lot, but on a global scale, it can have a huge impact. Global Warming is a serious problem, and it should be taken very seriously. Unless we take action now, we will have major consequences to deal with later on. These include, but are certainly not limited to, extreme weather, a decline in polar life, and effects on human health. It seems like Global Warming has become such a political issue that people tend to take a side based solely on the political party they support. This needs to stop. No matter where you fall on the political spectrum, you cannot ignore the facts. The temperature of our atmosphere has been increasing at an alarming rate in recent years. Global warming is happening, and action needs to be taken to stop it, no exceptions.…

    Global warming can no longer be given a blind eye. Long-term observations in the last century or so reveal that the U.S. climate is changing rapidly. According to the National Assessment Synthesis Team's U.S. Global Change Research Program in 2000, the average national temperature has risen by 1*F and precipitation has increased 5-10%. Although these trends have been more apparent in recent years, the projected warming for the 21st century is significantly higher. The increased temperatures are also very likely to be accompanied with "more extreme precipitation and faster evaporation of water". Today we see evidence of global warming via shrinkage of glaciers, thawing of permafrost, earlier melting and later freezing of ice on lakes and river, and shifts in plant and animal systems.…

    Nowadays, we are concerned with the increasing temperature nowadays, which has a great effect on the earth. When it becomes hotter, the most evident change we can see is in sea level. Icebergs all over the world are melting and change from ice to water, which has larger volume. As a result, more space has to be occupied to contain water instead of icebergs, and sea level increases. Many beaches are getting smaller, and some islands are even disappearing. It was also reported that some countries based on the islands of East Asia had to move to Australia because of the increasing sea level.…

    Climate change is a long-term alteration in the statistical distribution of weather pattern over periods ranging from decades to millions of years. The world is currently experiencing drastic change in temperature. This change can be felt in the tropical climate areas where the weather is getting hotter and hotter every day. The change in global temperatures and precipitation over time is due to natural variability or to human activity. It is also caused by accumulation of greenhouse effects (Arrhenius, 1896). Should we as humans let this problem worsen? Climate change will affect everything including humans, flora and fauna, and the environment.…

    Experts around the world have been warning about this for decades and have been urging governments to do more to slow down the rate of global warming. They warn that there is a 75% risk that global temperatures will rise a further two to three degrees in the next 50 years. The consequence of this would be dramatic. In fact a rise of just one degree would melt the Greenland ice sheet and drown the Maldives, but a three degree increase would kill the Amazon rainforest, wipe out nearly half of all species facing extinction and wreak havoc with crop yields due to weather changes.…

    For millions of years, the intricate balance between hydrosphere and atmosphere has resulted in the observed global pattern of seasons, cycle of snow and rainfall, summers and winters, droughts and floods. This has consequences on life in a myriad mystifying ways. Over a period of last two hundred years, man has been exercising enormous influence on climate primarily through his activity. The carbon dioxide content in the atmosphere is now steadily increasing. There is a forty percent decline in arctic ice thickness in recent history. It is estimated that the global mean sea level has already increased by ten to twenty centimeters.…
