First, the melting of ice caps and glaciers is releasing water into the oceans. Second, human activities, such as the burning of fossil fuels, combined with natural activities, it causes the rise of the earth's surface temperature.3 Second, climate change is already having a serious effect on every continent and throughout the world’s ocean. The consequences of sea level rise mainly reflected in three aspects: cultural heritages, indigenous communities and coastal lands. 4 First, sea level rise threats cultural world heritage. Data shows that 136 out of 700 listed cultural heritages throughout the world will be affected in the long term.
It would change our climate, but it would not bring us close to the level of uninhabitable Venus. A doubling in CO2 levels would make agriculture much more difficult due to shifts in climate that occur as a result of increasing temperature. CO2 can indeed cause a significant degree of warming if it is suddenly released into the atmosphere, as we have been doing for the past 150 years. Aside from that, increasing temperature can also cause the rising of sea level as the glaciers are going to melt at a faster rate like never before. Next, is the change in environmental health.
The planet has become much warmer everywhere. Ice has been melting worldwide so that the sea level has risen rapidly. Thus, global warming may cause numerous disasters such as hurricanes and tsunamis. The situation of global warming is severe right now, and it leads to public and animal endangerment. Polar bears may disappear as the sea ice continues to melt.
Global warming has been a highly debated topic for quite a bit of time now. Is it or is it not happening? Global warming is an increase of temperature that causes related changes in climate and the environment. This has been seen in Antarctica especially. The change of temperature in Antarctica due to global warming has had many effects on wildlife and the environment already.
Global Warming: Changing the Climate Control Policies For the past 10 years, 2000 until today, we have experienced some phenomenal natural disasters. For example, the 2004 Indonesia tsunamis, 2010 Haiti earthquakes, 2010 Icelandic volcano eruption, and massive hurricanes in the Atlantic, and they are leaving everyone wondering, why? Even though these are natural disasters and it seems there is nothing we can do to avoid these catastrophes; we can help control the climate around us. Climatologists have been warning the government all around the world of the possible effects due to global warming and there is still no agreement on the action that needs to be taken. Since we have the attention of everyone, now is the best time to take action against global warming.
Recent studies have shown that ninety-seven percent of scientists believe that manmade actions cause climate change (Samenow). The inconvenient truth is that climate change is a reality that must be addressed. The environment has become polluted, unpredictable, and dangerous as a result of climate change. The three major effects of climate change are: flooding, drought, and spread of disease. Scientists studying the polar ice caps have observed consistent annual increases in the rates at which they are melting; this indicate, that the temperature of Earth’s water is increasing and sea levels are rising.
1. Introduction The significance of this topic is to show the relationship between monitoring the Polar Regions using remote sensing techniques and the effects of climate change. The effect of climate change does not occur evenly around the world; some places warm faster than others. The Arctic and other Polar Regions are good examples of areas that are warming faster than other areas. The Earth’s average temperature has risen 0.6°C, while areas in the Arctic have risen up to 3.0°C in the last 20th century (Gardiner, 2008).
Yes, our earth is currently warming up, but who says this is a bad thing? Evidence has shown that it will be beneficial as it has in the past. Humans believe that they are significantly affecting the earth’s climate when it is most likely natural astronomical and earthly cycles. Really, through all of this substantiation, it may be confirmed that human activity does not bring about global warming and global warming is not a threat. Table of Contents
Natural Causes of Climate Change The earth’s climate is influenced and changed through natural causes like volcanic eruptions, ocean current, the earth’s orbital changes and solar variations. Volcanic eruptions - When a volcano erupts it throws out large volumes of sulphur dioxide (SO2), water vapour, dust, and ash into the atmosphere. Large volumes of gases and ash can influence climatic patterns for years by increasing planetary reflectivity causing atmospheric cooling. Tiny particles called aerosols are produced by volcanoes. Because they reflect solar energy back into space they have a cooling effect on the world.
Although the issue did not start to gain national attention until the early 2000s, scientists have been studying atmospheric gases and the effect that human consumption of fossil fuels has on the atmosphere and climate since the early nineteenth century (Rich). The overwhelming consensus among scientists today is that the climate is changing drastically and humans are causing it through specific, preventable actions (Rich). Global warming is caused by an increase in greenhouse gases, which, under normal conditions, it (the greenhouse effect) is what makes life sustainable by keeping the earth within a constant range of temperatures (Gore). About 30 percent of the light and the heat of the sun is reflected back into space, either by clouds, or by the earth’s surface (especially ice, which is particularly reflective.) About 20 percent of the light and heat from the sun is
