Lê Lan Lam – USTH BI3-044 Writing project 2: The role of CO2 in global warming Nowaday‚ climate change and global warming are very urgent problems of the world. There are many mixed opinions about the role of CO2 in those processes. Most of people – such as Rosanne Skirble write in “Scientists 95% Certain Climate Change Is Man-made”‚ or GPWayne with the article “Empirical evidence that humans are causing global warming” – believe that CO2 is the main factor and human – who release majority of greenhouse

Will Biofuels solve global warming? Global warming is caused by greenhouse gasses; these trap heat in the earth’s atmosphere that should escape from the earth. Global warming is causing sea levels to rise and ice caps to melt this could lead to coastal cities flooding‚ droughts in area’s which usually get rain and less crops to list only a few affects. The cause of global warming is “greenhouse gasses” these gasses include nitrous oxide carbon dioxide and water vapour. Cars produce CO2‚ H20 and

countries are forging new treaties and protocols to create a global paradigm shift in the way we handle climate change. After analyzing the different articles in the reading I noticed a reoccurring theme in most of the articles. With the recent shifts in the weather countries have been coming together more frequently to discuss the issue. This is a positive move forward‚ but it seems that all that comes of the gatherings on global warming is hard promises by countries to cut back on emissions to a

Directed by Davis Guggenheim and featuring former United States vice president Al Gore‚ the documentary zeros in on the subject of global warming and how it is affecting and will affect the planet Earth. The Effectiveness of Al Gore Technical and cinematic achievements aside‚ I believe the best contribution of this film is that it has made the issue of global warming accessible to ordinary individuals. Gore plays the role of environmental spokesperson well. He provides a believable and authoritative

Carbon Emissions and Global Warming Carbon dioxide is released into the atmosphere every time we burn fossil fuels such as gas‚ coal or oil. In a natural carbon cycle‚ carbon dioxide is re-absorbed by plants and trees. However‚ the rate in which we are burning fuels is way too fast for trees and plants to absorb and convert into breathable air. In addition to that‚ many rainforests have been lost because of the cutting down of trees‚ which doesn’t help in the already existing problem. The effect

PERSUASIVE SPEECH ON GLOBAL WARMING by: Jennifer Zelmer Introduction: We all know about global warming‚ but do we really care or try to do at least some of the things that will help stop it or at least slow it down? 1) Over the last century our planets temp. has risen 1 degree. I know that doesn’t sound like much but it’s been enough to melt a lot of the polar ice caps and glaciers. A) The hottest years ever recorded were in the late 1990’s and early 2000’s. B) In 2007 there was

Global warming and how thunderstorms and floods effect agricultural growth. Thunderstorms and flooding effect how and what we eat everyday because of the cost. Once global warming is under control‚ the cost to create food will be reduced immensely. This is important because of poverty that has been created because many different nations are not able to feed their people. The authors describe how the absence of water effects the growth and how drought effects feeding people in that area and the

Global Warming - Fact or Fiction? - Speech The Earth is rapidly heating up or is it? If it is‚ the next few decades may witness Biblical scenes of rising temperatures‚ crop failures‚ flooding and the extinction of different species. On the other hand‚ increases of Carbon Dioxide in our atmosphere may well encourage plants and trees to thrive like never before. Whom can you believe? One thing is certain the debate on climate change and Global Warming is heating up. It is surely right for

Global Warming affects Biodiversity There has always been a link between climate change and biodiversity. As the climate changes‚ the animals in the affected areas have to either adjust or leave. Although climate changes have been occurring throughout history‚ the rapid climate changes of today are resulting in species not being able to adapt quickly enough and undergoing species loss. Some species may adapt well to the climate changes such as an increase in bugs and pests‚ but others‚ such as Arctic

concentrations produced by human activity. While there are arguments in favour of natural cause of the global warming‚ I think on balance that the arguments against carry greater weight. A common skeptic argument is that climate has changed naturally in the past‚ long before SUVs and coal-fired power plants‚ and this somehow tells us that humans can’t be the main cause of the current global warming. Peer-reviewed research and simple logic show this is not the case. There are a number of different
