21-Century Climate Change

Climate change is the most serious issue humankind is facing in the 21th century. Future generations depend on our ability to make the necessary social changes, before reaching the tipping point of irreversibility, which will lead the planet into a catastrophe incompatible with life.

The earth’s climate has been changing and will continue to do so in the future. It is only going to keep on getting worse and it is getting to the point where humans will most likely end up in a situation of life threatening diseases and even death. Contagious diseases are spreading menacingly due to weather extremes as heat wave, droughts, cyclones, floods, and tornados (Dhaka). That is just the start of the effect of climate change and its consequences. Many scientists have already warned that millions of people would die in this century because of climate change unless the major reduction in greenhouse gas emissions is made (Dhaka). However, there are more than just reducing greenhouse gas emissions to help solve for climate change.

Throughout the middle of the twentieth century, until now, there has been debate over the existence of climate change. Climate change is the increase of earth’s inclusive temperature of the atmosphere, and the side effects caused by rising temperatures. Climate change is caused by many reasons: burning of fossil fuels, agriculture, landfills, and deforestation. Climate change is mainly caused by greenhouse gases and humans. The effects of climate change are detrimental to earth; the effects have lead to stronger and more intense hurricanes, a rise in temperature, and the melting of glaciers(“Global Climate Change: Effects”).

Climate change is evident throughout the world and is a major issue. It is no secret that our planet is getting warmer. Global warming is now recognized in the scientific community as a real problem. There are multiple aspects that are causing this issue. Majority of the warming is caused by greenhouse gases. Volcanic eruptions and changes in the intensity of solar radiation have offset the warming partially. It is estimated that average annual temperatures will increase 3.5°F-9.5°F by the century’s end.

Glaciers are melting, sea levels are rising, forests are drying and wildlife is suffering, these are all results of the apparent rise in global temperatures and it has become more

Rising sea levels has two main causes, increased glacier melt and the water itself expanding as it gets warmer known as thermal expansion (U.S.). The increased heat in water that is causing glaciers to melt and the water to expand is largely due to greenhouse gas emissions (U.S.). The dependence on fossil fuels by many countries around the world means that there will be difficulties in reducing continued damage to the atmosphere from greenhouse gasses (“Causes”). Another reason that greenhouse gas emissions have had such negative effect stems from the destruction of forests, particularly those in tropical locations (“Causes”).

Rising sea levels are occurring from global warming and extreme climate change. The burning of fossil fuels and greenhouse gasses has released masses amount of heat into our atmosphere which is getting trapped, causing our earths temperature to rise. Our oceans have absorbed up to 80% of this additional heat. Our Earth is not used to the higher temperatures which has had a dramatic impact on Ice Glaciers, causing them to melt which leaves sea levels rising. This problem is on going and each and everyday we are all contributing to it.

Over the next century, the temperature is estimated to rise by 2.5 to 10 degrees Fahrenheit. The biggest cause to this jump in temperature is highly believed to be caused by greenhouse gases used by humans. Also, with this increased climate change, heat waves and droughts are expected to last much longer than usual. Cold waves on the other hand are projected to be a whole lot warmer than usual and also a lot less frequent. Climate change is the result of human activity and carelessness to take care of the earth. However, there are solutions

Climate change is a challenge facing our planet right now. Long-term effects may develop as a result, causing threats to natural resources, human health, and the economy. The concern is rising with the amount of carbon emissions and greenhouse gases in our delicate atmosphere.

It is widely held that climate change is real and happening now Case (2006) as global average temperature has warmed about 0.8°C within the past century. Coupled with this, the past three decades has witness a global average warming of 0.6°C (Hansen et al., 2006). This is largely to due to human induced factors (IPCC, 2001). A recent report produced by the U.S. National Academy of Sciences confirms that the last few decades of the 20th century were in fact the warmest in the past 400 years (National Research Council, 2006). The IPCC also projects that if greenhouse gas emissions, the leading cause of climate change, continue to rise, the mean global temperatures will increase 1.4 – 5.8°C by the end of the 21st century (IPCC, 2001). In a similar

In the present times unequivocal climate system is quite evident, which is increasing the global average air and ocean temperature and widespread melting of snow, ice with rising global average sea level and more significant effect of global warming is climate change which intern affecting the human

Nowadays, global warming has increased dangerously in a way that affects every creature’s existence and health. On the one hand, there are the natural causes. Over the years there have been massive explosions from volcanoes which have affect the atmosphere and the temperature. Another problem is that the sea levels are rising worldwide because the ice is melting. To be exact, many cities are in danger of sinking because of that.

A way to explain rising sea levels is El Niño and La Niña. These two words are considered to be natural to the global climate system. El Niño is known as events which contribute to the warming of central and eastern tropical Pacific areas, and La Niña is the opposite which means the cooling of the areas which were listed above. El Niño was originated during the late 19th century by the Spanish. This term was translated to “Christ Child” because it was created on December 2, close to Christmas. El Niño was discovered when there was an odd occurrence with the wind patterns. In the past, before El Niño was invented, people who have been studying the wind patterns know that the

The climate change that is happening is causing a lot of damage. In the last 20 years the sea level has raised 0.13 inches. The major ice caps are melting at a rapid speed, and the oceans are warming up. In the last decade the temperature around the world was the warmest ever on record. If the climate continues at the rate it is now, water availability will decrease and drought will probably occur (Grovenburg 1-9).

Climate can be defined as the mean of temperature, wind patterns, quantity of water vapor in the air, which is humidity and rainfall that has continued from the past up until the present. The cause of climate change was expected to be through natural phenomena’s, for example volcanic eruptions and solar activity. However, the change in climate is not due to the natural effects but solely through human activities. From generation to generation the human race has immeasurably impacted the earth’s environment through farming of land and animals, building cities, and establishing factories and power plants. Each factor has contributed to the negative impact of the earth’s environment in many different ways. The temperature is beginning to increase; glaciers and polar ice caps are melting, carbon dioxide levels are rising, causing the ozone layer to deplete. As of today, one of the biggest problems not only for human beings but also for this planet is known to be climate change. When greenhouse gases are increased, it causes the increase in sea levels and an increase in global temperatures. As a result, serious weather patterns are advancing. All of these changes will destroy houses, land, and foundation. Therefore, climate change is another significant environmental, social, and economic threat facing this planet.
