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?
The Arctic as most know is known for its fisherman and whalers, whom in the past overfished and whaling for the uses of oil, but cause a major downfall in the number of Arctic marine life. AS mentioned before with the climate change there will a larger number of fishing and whaling vessels due to the decrease of sea ice and the opening of Arctic waters that have never been accessible. Looking at the Arctic portal I found a list of restrictions that would be major to the fishing industry; 1. Restrictions on catch and effort, for instance by setting the total allowable catch (TAC) and allocating the TAC by means of national quotas. 2.
Global warming has been a giant issue in our world today the rising of seas, melting of ice caps, experiencing some of the worst natural disasters in centuries. We have known of this since 1980 to be exact. I've just got done reading two really good articles on global warming. Two articles that I read were Greenland Ice Cores: Frozen in time and the other article is named the Rising Seas . These two articles really informed me on whats happening in the world due to global warming.
Over the years, the silt has been collecting in Lake Mead, the nation’s largest reservoir, and it is predicted that over the next few hundred years this lake will fill up with silt. This could threaten the entire Colorado River reservoir system. Just in the past 10 years, Lake Mead’s water levels have dropped by more than 100 feet and the basin is only half full. Something needs to be done to stop the trends and even
This indicates tree line advance, with a consequent movement north of associated species – for example lichens, mosses, fungi and birds such as the woodpeckers. Changes in the duration and timing of the growing season have also been detected, although patterns again vary geographically. Loss of sea ice due to warming may also affect the habitat of seals, polar bears, fish and other animals. Problems for polar bears have already been recorded – they have to wait longer each year for the sea ice to form, deal with diminished hunting grounds and undertake exhausting open-water swims to find ice. As waters warm, numbers of fish species such as the Arctic char may decline, whereas others may increase, for example cod and hearing.
Companies have deposited their waste in the lake, which has caused the lake to be shut down because humans are getting sick and even dying from the polluted waters. Viruses, pathogens, chemicals and toxins are all part of this pollution, which affects recreation, jobs, and habitats of animals. Fishermen have not spent money fishing for sport due to the drastic reduction of the salmon population at Lake Huron. Recreational hours at the lake have also seen a drastic decrease. This devastation affects a majority of the U.S. being one of our largest sources of fresh water, and will only continue to deplete, as companies carelessly dump their waste into the lake.
In 1998, 300 million humans, one in twenty of us, had to leave their homes for a week, and month, a year, forever because of rising waters. (McKibben 682) This is evidence that global warming, or the process of the earth heating up, is really happening. McKibben also says “Severe storms have already grown more frequent and more damaging. The seasons are less steady in their progression. Some agriculture is less reliable” (McKibben 683).
states. At the same time, snow, ice, and several entire glaciers on the mountain melted, forming a series of large lahars (volcanic mudslides) that reached as far as the Columbia River. Less severe outbursts continued into the next day only to be followed by other large but not as destructive eruptions later in 1980. By the time the ash settled, 57 people (including innkeeper Harry Truman and geologist David A. Johnston) and thousands of animals were dead, hundreds of square miles reduced to wasteland, over a billion U.S. dollars in damage had occurred ($2.74 billion in 2007 dollars[1]), and the face of Mount St. Helens was scarred with a huge crater on its north side. At the time of the eruption, the summit of Mount St. Helens was owned by the Burlington Northern Railroad, but afterward the land passed to the United States Forestry Service.
As the polar ice caps melt and the globe warms everything as we know it will change. As the weather shifts so will the winds, causing our crops to grow differently and not as abundantly as before. As the population increases the food sources will decrease. Over population will cause crops as well as water to no longer be plentiful. With each threat the chance of extinction of animals, crops and ultimately man exists.
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,
