 LOVE 201: Global Change#1
On the negative side in North America, for instance, the panel found that forests and their wild inhabitants in the East and parts of the mountain West might not be able to migrate northward or upward fast enough or far enough to adjust to the warming climate.
The new report of the intergovernmental panel said that tundra and taiga in North America may be reduced by two-thirds in the next century and that the southern boundary of the area covered by permafrost should shift northward by about 300 miles over the next 50 years, threatening roads, buildings, pipelines and other structures.
Largely for this reason, according to the panel, Africa may be the continent most vulnerable to climate change, because its economy consists largely of rain-fed agriculture and many of its farmers are too poor and ill equipped to adapt.

 The IPCC Assessment Process
The Intergovernmental Panel on Climate Change (IPCC) was established in 1988 under the auspices of the United Nations Environment Programme and the World Meteorological Organization for the purpose of assessing "the scientific, technical and socioeconomic information relevant for the understanding of the risk of human-induced climate change.
Because the assessments of the IPCC are the most comprehensive and balanced evaluations of the climate change issue, however, its work is probably the single most important foundation on which climate policy is built [2].
Points of dispute in the science of climate change are usually resolved either by developing appropriate intervals of uncertainty around certain projections or by crafting language that reflects the different viewpoints of experts within the scientific community and the reasons that the differences exist [4].

 Global Climate Change: The 1995 IPCC Report
The Intergovernmental Panel on Climate Change (IPCC) issued assessments of global climate change in 1990 and 1995 (the executive summaries of the latter report are available from IPCC).
The IPCC panel concluded that "changes in global mean surface air temperature and from changes in geographical, seasonal, and vertical patterns of atmospheric temperature, suggest a discernable human influence on global climate".
Although the IPCC report is based on the work of a large number of researchers from around the world, not all scientists agree with the panel's conclusions (for one example, see the World Climate Report).

Climate change is a primarily influenced by the total stock of GHGs in the atmosphere and not by annual GHG emissions.
India is highly vulnerable to climate change as its economy is heavily reliant on climate-sensitive sectors like agriculture and forestry, and its low-lying densely populated coastline is threatened by a potential rise in sea level.
India’s strategy in contributing to global efforts to reduce the risk of climate change has been to develop the institutional capacity to formulate, assess, and implement economic and technical responses to climate change issues; focus on the transfer and adaptation of technology; and integrate sustainable development with national development programmes.

The US Climate Change Science Programme, which yesterday released its own report saying climate change was being affected by man-made pollution, said it wanted as many experts and stakeholders as possible to comment on the draft IPCC report.
The IPCC assessment is written by scores of scientists - who can draw on the expertise of hundreds more researchers - to produce the most definitive and authoritative assessment of climate change and its impacts.

In fact, the observed changes in climate cannot be explained by natural phenomena alone (e.g., changes in solar output and volcanic emissions) as shown in, nor anthropogenic emissions of greenhouse gases and aerosols alone.
Vulnerability is defined as the extent to which a natural or social system is susceptible to sustaining damage from climate change, and is a function of the magnitude of climate change, the sensitivity of the system to changes in climate and the ability to adapt the system to changes in climate.
The IPCC has continued to provide scientific, technical and socio-economic advice to the world community, and in particular to the 170-plus Parties to the UNFCCC through its periodic assessment reports on the state of knowledge of causes of climate change, its potential impacts and options for response strategies.

Intergovernmental Panel on Climate Change releases Summary for Policymakers for the report "Climate Change 2007: The Physical Science Basis", approved by the U.S. government.
Climate change refers to any significant change in measures of climate (such as temperature, precipitation or wind) lasting for an extended period (decades or longer).
The fact that the magnitude of the observed warming is large in comparison to natural variability as simulated in climate models is suggestive of such a linkage, but it does not constitute proof of one because the model simulations could be deficient in natural variability on the decadal to century time scale.

This most recent research from the IPCC concludes that global warming is "unequivocal" and that human activity is the main driver of this warming, asserting with near certainty — more than 90 percent confidence — that carbon dioxide and other heat-trapping greenhouse gases from human activities have been the main causes of warming since 1950.

The United Nations Intergovernmental Panel on Climate Change [IPCC] projects an increase in global mean temperature of between 1.4° and 5.8° C (2.7° to 10.8° F) by the year 2100 [Source: IPCC Synthesis Report, 2001].
Recent regional changes in climate, particularly increases in temperature, have already affected terrestrial and marine ecosystems in many parts of the world.
Significant disruptions to ecosystems from disturbances (e.g., fire, insect outbreaks) are expected to increase and changes in climate could also increase the probability of abrupt, non-linear changes in many ecosystems.

 BEYOND THE IVORY TOWER: The Scientific Consensus on Climate Change -- Oreskes 306 (5702): 1686 -- Science
Created in 1988 by the World Meteorological Organization and the United Nations Environmental Programme, IPCC's purpose is to evaluate the state of climate science as a basis for informed policy action, primarily on the basis of peer-reviewed and published scientific literature (3).
That hypothesis was tested by analyzing 928 abstracts, published in refereed scientific journals between 1993 and 2003, and listed in the ISI database with the keywords "climate change" (9).
Some abstracts were deleted from our analysis because, although the authors had put "climate change" in their key words, the paper was not about climate change.

 Scientific opinion on climate change - Wikipedia, the free encyclopedia
The statement stresses that the scientific understanding of climate change is now sufficiently clear to justify nations taking prompt action [2], and explicitly endorsed the IPCC consensus.
The IPCC's conclusion that most of the observed warming of the last 50 years is likely to have been due to the increase in greenhouse gas concentrations accurately reflects the current thinking of the scientific community on this issue.
On May 2, 2006, the Federal Climate Change Science Program commissioned by the Bush administration in 2002 released the first of 21 assessments that concluded that there is clear evidence of human influences on the climate system (due to changes in greenhouse gases, aerosols, and stratospheric ozone) [6].

 Climate Change - IPCC Confirms Urgency of Climate Change
As a part of these efforts, Patrick Gonzalez, one of the Conservancy's leading global climate change scientists and an expert reviewer for the latest IPCC report, is analyzing potential vegetation shifts due to global climate change.
For example, he notes that climate change has caused vegetation zones that stretch across the entire African continent to shift 16-19 miles in the last half of the 20th century.
Armed with information about what types of changes may occur, the Conservancy is also integrating climate change into conservation plans for specific sites or states and adapting conservation actions to account for future climate change.

 Climate Change
Because the climate naturally exhibits both statistical variability and long-term patterns of change, it remains difficult to distinguish "natural" from human-caused climate effects.
Since climate change first appeared in the news, scientists have refined and to some extent moderated initial estimates of future warming.
Computer-generated climate models have gradually improved their ability to generate today's known conditions when given data about the past - a crucial test of a model's accuracy regarding the future.
