Global Warming In Canada Global warming has become one of Canada’s popular topics of debate. With the effects on the people and the world, it is a case that needs to be addressed rapidly. This ongoing issue of global warming is a matter that is in dire need of change. Through this climate change, our country and people have endured a lot of economical, environmental and health problems throughout the country. These major themes of Global warming have caused distress on our country, and without change, Canada and the world will slowly become nothing.
However, surface air temperatures north of 65oN have been warning at roughly twice the global rate for the last four decades (1965-2005). The warming of the atmosphere, which leads to warmer soils, seems to be having an effect on the Arctic tree line – the boundary between the boreal forest and the tundra. Evidence for an advance of the tree line has been found in Alaska. Studies of the age of trees along transects that cross the tree line from the forest to the tundra show that that they becoming progressively younger. This indicates tree line advance, with a consequent movement north of associated species – for example lichens, mosses, fungi and birds such as the woodpeckers.
Due to, again warmer temperatures both maximum and minimum we are seeing ice melt. “Data from NASA's Grace Satellites show that the land ice sheets in both Antarctica and Greenland are losing mass. The continent of Antarctica has been losing more than 100 cubic kilometers (24 cubic miles) of ice per year since 2002” (Global Climate Change: Key Indicators, 2014). Warming air and land temperatures seem to be causing the land ice and artic ice to melt. Where is all this melting ice going?
ABSTRACT Global warming causes many changes in weather patterns including greater temperature variability and more extreme temperatures. In this study we examined the damage and recovery in Aesculus glabra (Ohio buckeye) in Trelease Woods after a late frost in the spring of 2007, potentially caused by global warming. 1) If temperature and wind gradients directly affect the pattern of damage and recovery of Ohio buckeye, then as the distance of Ohio buckeye from the forest edge increases the percent leaf damage done by frost will decrease. 2) If the total leaf area available for photosynthesis in an Ohio buckeye directly affects its recovery from frost damage, then as percent leaf damage increases, recovery (based on percent canopy fullness,
Global Warming By Amanda Lardino Sci 275 What are the main causes of global warming? Is there things we can do to prevent it? Those are two of the main questions that have come to mind about the way to focus our thoughts on what can be done to decrease this issue in the world today. One of the major atmospheric issues that has been destroying the environment for years is global warming. I have read that in the present compared to the past global warming has increased tremendously.
One more similarity is the equipment they used to get the results for example they both used temperatureDetermining global warming effects on weather can be done in many different in these two articles I found that you can use ice or water. In the rising of the seas they explain how the melting of the ice caps raise the sea level but in the greenhouse. It breaks down how they can use ice to determine the future weather. Global warming is something more people need to be aware of and get more knowledge on, because after reading these two articles I found out what our world might become just by looking into the past. These two article had there similarities and differences in how they go about finding out about the past but yet both are very
Final Paper: Reconstruction of The Changing Arctic Brett Wegleitner Concordia College The 21st century has been one of many changes in both the environment and how nations will forever change the Arctic, as it is now perceived. The arctic is one of the most fragile places on Earth as it holds the key to many new resources that have barely been touched and also a huge commodity for countries that would like to exploit the Arctic waters as new shipping lanes emerge due to global climate change. Climate change has been the largest factor in the changing Arctic as the ice is retreating further and allowing for more ships to have access and for corporations to begin extracting hydrocarbons to be shipped all over the world as we become more
The Globe is losing its Cool Global Warming Melissa Moran University of Phoenix Axia collage Professors name SCI 275 October 21, 2009 There are many reasons for the change in the climate. Climate change also known as global warming is the change in the average temperature of the earth surface, and the change in wind and precipitation. Global warming is caused by releasing fossil fuels into the atmosphere. Many factors such as human activity and greenhouse gas emissions contribute to global warming. Global warming also has natural causes though they are often down-played in the media.
1.10) What is the effect of climate change on biodiversity in the oceans and on land? The link between climate change and biodiversity has been established a long time ago. Even though throughout the history of Earth, the climate has always changed and species and ecosystems have come and gone, rapid and abrupt climate change affects species’ ability to adapt and ecosystems and thus, biodiversity loss increases. There are a number of aquatic and land species that have been red flagged by the World Wide Fund for Nature (WWF). Some of them are: • South American Sea
First off, it raises the temperature, and also the excess carbon dioxide that does not go into the atmosphere eventually gets dissolved in the oceans causing them to acidify. Water Changes Changes in water include changes in the water level, temperature, and acidity. In the last hundred years, the sea level has risen about “15 cm (6 inches) due to melting glacier ice and expansion of warmer seawater”, and in the next ninety years, “models predict that sea level may rise as much as 59
