Climate Change In The World Inevitable By 2100

599 words - 3 pages

Over 80% of the world’s ice-free land is at risk of profound ecosystem transformation by 2100, a new study reveals. “Essentially, we would be leaving the world as we know it,” says Sebastian Ostberg of the Potsdam Institute for Climate Impact Research, Germany. Ostberg and collaborators studied the critical impacts of climate change on landscapes and have now published their results in Earth System Dynamics, an open access journal of the European Geosciences Union (EGU).

The researchers state in the article that “nearly no area of the world is free” from the risk of climate change transforming landscapes substantially, unless mitigation limits warming to around 2 degrees Celsius above preindustrial levels.

Ecosystem changes could include boreal forests being transformed into temperate savannas, trees growing in the freezing Arctic tundra or even a dieback of some of the world’s rainforests. Such profound transformations ...view middle of the document...

“The research shows there is a large difference in the risk of major ecosystem change depending on whether humankind continues with business as usual or if we opt for effective climate change mitigation,” Ostberg points out.

But even if the warming is limited to 2 degrees, some 20% of land ecosystems – particularly those at high altitudes and high latitudes – are at risk of moderate or major transformation, the team reveals.

The researchers studied over 150 climate scenarios, looking at ecosystem changes in nearly 20 different climate models for various degrees of global warming. “Our study is the most comprehensive and internally consistent analysis of the risk of major ecosystem change from climate change at the global scale,” says Wolfgang Lucht, also an author of the study and co-chair of the research domain Earth System Analysis at the Potsdam Institute for Climate Impact Research.

Few previous studies have looked into the global impact of raising temperatures on ecosystems because of how complex and interlinked these systems are. “Comprehensive theories and computer models of such complex systems and their dynamics up to the global scale do not exist.”

To get around this problem, the team measured simultaneous changes in the biogeochemistry of terrestrial vegetation and the relative abundance of different vegetation species. “Any significant change in the underlying biogeochemistry presents an ecological adaptation challenge, fundamentally destabilising our natural systems,” explains Ostberg.

The researchers defined a parameter to measure how far apart a future ecosystem under climate change would be from the present state. The parameter encompasses changes in variables such as the vegetation structure (from trees to grass, for example), the carbon stored in the soils and vegetation, and freshwater availability. “Our indicator of ecosystem change is able to measure the combined effect of changes in many ecosystem processes, instead of looking only at a single process,” says Ostberg.

He hopes the new results can help inform the ongoing negotiations on climate mitigation targets, “as well as planning adaptation to unavoidable change.”

Change is Inevitable: "Where the Red Fern Grows" by Wilson Rawls

601 words - 2 pages clear that these changes were completely unavoidable if Billy were to live. To sum it up, a very strong theme in the book Where the Red Fern Grows is that change is inevitable. The fistfight, the big storm and Billy’s dogs dying were all great examples of this theme. I think change is inevitable is a great theme because it shows that there is no use trying to fight the flow of life. Be pragmatic, you can do little to change the world only by yourself. Where the Red Fern Grows is a great novel that strongly shows that change is inevitable. Bibliography Rawls, Wilson. Where the Red Fern Grows. Evanston: McDougal Littel, 1997.

Moreover, studies (such as Meier, 1984) have found evidence that 2-6 centimeters of sea level rise can be explained by the melting of glaciers (Warrick, 1990). According to the International Programme for Climate Change’s estimates sea level will rise between “0.3 and 1.0 meter by 2100, with a best-guess estimate of 0.5 meter” (World Resources, 1998-99). A rise in sea level
