Hundreds of sensitive species of plants have become extinct. The wet areas have become Dampier and dry have become drier. Thus it can be seen that climate change has directly or indirectly affected our oceans, weather, food and health. According to a report by NASA, the global temperatures have risen by 1.7oF since 1880 and land ice is decreasing at a rate of 286 Giga tonnes per year. Although many organizations are working on the issue of Climate change, there needs to be
Many effects can be seen in the future if global warming continues. It includes economic consequences, more hurricanes, a spread of diseases and earthquake. Human-emitted greenhouse gases cause excess heat which has warmed the world’s oceans during the past decades. Water expands when it warms, which leads to sea level rise (USNRC “Climate Change: Evidence, Impact, and Choices”). Moreover, the global warming has affected the life of other living things such as animals and plants.
Today, based on the topic environment, I am going to discuss on the cause and effect of global warming that is happening on our mother earth. What is global warming? Global warming is the term used to describe the gradual increase of the average temperature on the Earth’s atmosphere and the oceans, which is believed to cause climate change on earth permanently. Based on scientific research on climate change due to global warming, the average temperature rise is between 0.4 to 0.8°C for the past 100 years. Scientists also predicted that the average temperature could increase between 1.4 to 5.8°C by the year 2100.
Climate change may potentially be the biggest global health threat in the 21st century. Our response requires a new public health movement that consists of multi-disciplinary and multi-sectoral solutions that leads to coordinated thinking and action across governments all over the world, international agencies, NGOs, and academic institutions. Warmer temperatures will lead to even hotter days and even more frequent and longer upcoming heat waves. According to the U.S Global Change Research Program these changes will lead to an increase in heat-related deaths all over the world, reaching as
THE DANGERS OF GLOBAL WARMING Global warming is the big environmental issue we are facing today as a greatest challenge which we need to get it solved permanently. In fact, global warming is the continuous and steady process of increasing in the temperature of earth surface. It needs to be discussed widely by all countries worldwide to stop the effects of it. It has impacted the nature’s balance, biodiversity and climatic conditions of the earth over decades. Global warming is a gradual process of heating of earth’s surface and whole environment including oceans, ice caps, etc.
A change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. DEFINITION The main cause which is effecting our climate to change is the burning gas in air. GHGs are released into the atmosphere when fossil fuels are burned. The carbon dioxide gas and GHGs (GREEN HOUSE GAS) gets abundant in the atmosphere which effects our climate change CAUSE OF CLIMATE CHANGE Poisonous gases are stored and when they are released in the atmosphere they go and mix with the semi-permanent gas and it then forces our environment to get change. SOME EFFECTS OF CLIMATE CLIMATE: The mighty Himalayas protect the sub-continent from the cold winds of Central Asia.
Carbon dioxide emanations is the most vital reason for the whole earth’s temperature boost. CO2 is made by flaming sources, such as oil, regular gas, diesel, natural diesel, petrol, natural petrol, and ethanol. Most people do not know that when carbon dioxide is discharged to the environment, it stays for 100 to 200 years. As a result, this leads to an expanding concentration of carbon dioxide in the air, which thus causes the normal temperature of the earth to raise. Martin Rees (2016) , a professor of cosmology and astrophysics , writes in his article ”Human Induced Threat” that the atmosphere of CO2 focus is increasing for the most part because of the heated of fossil powers.These auto fumes vent these gasses into the air, and they turn out to be a piece of the air, leading to global
Climate change can also be defined as a change in global temperatures for extended durations (Maqbool, 2013). The health and survival of humans and ecosystems on the Earth depends on the world’s climate (McMichael, 2003). King (2004) believed that climate change is a threat to human civilisation (Gill et al., 2009, p.324). Global warming, its consequences and human intervention The Earth’s surface temperature worldwide has risen by nearly 0.50C since 1975 (Hansen et al., 1999; Jones et al., 1999; as cited in Hansen et al., 2000, p.9875); and this increase has been attributed to the rising human activities which release GHGs into the Earth’s atmosphere (Hansen et al., 2000). Heating up of the Earth’s surface adds more vapour to the atmosphere which further builds up increases the moisture levels in storms (Meehl et al., 2000, p.433).
Climate change is believed to be the biggest issue facing the Earth. It is a long-term change in the Earth’s temperatures and climate (“Climate Change”, Dictionary.com). Our atmosphere is part of the reason why we can live on Earth with reasonable temperatures. Humans have been emitting unnatural greenhouse gases, like coal, oil, and gas. This is changing the natural systems that take place in our atmosphere.
Nowadays, there are so many problems and issues that the world is facing. Most of the governments try their best to overcome these problems. One of the major problems that the world has always suffered from, but increased lately, is global warming. By definition, it is the increase in the earth’s temperature due to the increase of emission of greenhouse gases. This emission of greenhouse gases has increased drastically in the past few years.
