Earth Care Group Blog: Climate Change Impacts

This is the first entry in our new feature, the Earth Care Group blog. Our first entry was written by Tommic, our co -moderator, and deals with climate change impacts. It will be posted in three parts. This part deals with glaciers and is a comprehensive review of the reality of the state of the world. There will be two more parts posted within this week and we invite serious discussion of the reality and the opportunity as humans to take action to preserve the delicate climate balance of our only home.Thank you to Tommic for this comprehensive essay.

In the future we will invite others to contribute postings to this blog on any environmental topic of their choice. We want to create a group where information is not hindered by political and ideological barriers. A place where truth can be discussed in order for solutions and actions to follow. I hope you will be a participant in this.

Thank you,
Jan

Climate Change Impacts: by Tommic

Global warming has become perhaps the most complicated issue facing world leaders. On the one hand, warnings from the scientific community are becoming louder, as an increasing body of science points to rising dangers from the ongoing buildup of human-related greenhouse gases — produced mainly by the burning of fossil fuels and forests. On the other, the technological, economic and political issues that have to be resolved before a concerted worldwide effort to reduce emissions can begin have gotten no simpler, particularly in the face of a global economic slowdown.

At the heart of the debate is a momentous tussle between rich and poor countries over who steps up first and who pays most for changed energy menus. People worldwide must come to the realization that we will have to pay now or later but we will pay in the end and the cost to the economies of the world will suffer greater the longer we wait.

96 percent of the worlds glaciers are shrinking.

The continued retreat of glaciers will have a number of different quantitative impacts. In areas that are heavily dependent on water runoff from glaciers that melt during the warmer summer months, a continuation of the current retreat will eventually deplete the glacial ice and substantially reduce or eliminate runoff. A reduction in runoff will affect the ability to irrigate crops and will reduce summer stream flows necessary to keep dams and reservoirs replenished. This situation is particularly acute for irrigation in South America, where numerous artificial lakes are filled almost exclusively by glacial melt. Central Asian countries have also been historically dependent on the seasonal glacier melt water for irrigation and drinking supplies. In Norway, the Alps, and the Pacific Northwest of North America, glacier runoff is important for hydropower.

Pine Island glacier in Antarctic is being depleted at the rate of 16 meters per year loss of ice depth Larson ice shelves a and b are already gone with Larson B being the size of Rhode Island

The recent collapse of Wordie Ice Shelf, Prince Gustav Ice Shelf, Mueller Ice Shelf, Jones Ice Shelf, Larsen-A and Larsen-B Ice Shelf on the Antarctic Peninsula has raised awareness of how dynamic ice shelf systems are. Jones ice Shelf had an area of 35 km2 in the 1970s but by 2008 it had disappeared. Wordie Ice Shelf has gone from an area of 1500 square kilometers in 1950 to 140 km2 in 2000. Prince Gustav Ice Shelf has gone from an area of 1600 km2 to 11 km2 in 2008. After their loss the reduced buttressing of feeder glaciers has allowed the expected speed-up of inland ice masses after shelf ice break-up. . The Wilkins Ice Shelf is another ice shelf that has suffered substantial retreat. The ice shelf had an area of 16,000 km2 (6,200 sq mi) in 1998 when 1,000 km2 (390 sq mi) was lost.In 2007 and 2008 significant rifting developed and led to the loss of another 1,400 km2 (540 sq mi) of area.This is the first entry in our new feature, the Earth Care Group blog. Our first entry... more
