Definition Of Climate Change

Under the logic of the FCCC definition of climate change, there is exceedingly little room for efforts to reduce societal or ecological vulnerability to climate variability and changes that are the result of factors other than greenhouse gases. From the broader IPCC perspective on climate change, adaptation policies also have benefits to the extent that they lead to greater resilience of communities and ecosystems to climate change, variability, and particular weather phenomena.

The group turned back to Thompson's definition of climate change as a human rights issue. It is necessary that governments, NGOs, and individuals make the connection between human development and climate change. There is no universal definition of climate change as a practice area. What are clear are the various steps that governments and industry are taking to regulate greenhouse gas emissions and their impact on the environment.

Rising global temperatures will bring changes in weather patterns, rising sea levels and increased frequency and intensity of extreme weather. The effects will be felt in the UK; internationally there may be severe problems for people in regions that are particularly vulnerable.

Extended periods of above-normal temperatures and below-normal rainfall are key factors that contribute to an active wildfire season. Available moisture is rapidly lost due to high evapotranspiration rates under hot and dry conditions. The effects of climate change so far include rising temperatures, higher sea levels and more frequent extreme weather events like floods. All of these are expected to become more severe.

Any imbalance results in a change in the average temperature of the earth. The evidence comes from direct measurements of rising surface air temperatures and subsurface ocean temperatures and from phenomena such as increases in average global sea levels, retreating glaciers, and changes to many physical and biological systems. It is likely that most of the warming in recent decades can be attributed to human activities (IPCC 2001)2. It is due to the existence of the greenhouse gases, the temperature on planet earth does not average zero degrees! These naturally occurring gases help to keep the temperature at a desirable 59 degrees.

Global temperatures are expected to rise faster and faster in the future, and our expanded population may be unable to adapt to the ecological changes. Some of these social mechanisms are good for humanity, and some are bad, such as war. The reason for this is that we have come to understand that the effect of the changes we make to our environment will increase the temperature in many locations on the planet, but will also cool a few places.

In light of this, the thing you know of as climate modification is actually referred to as global climate change. In addition, many important diseases are highly sensitive to changing temperatures and precipitation. These include common vector- borne diseases such as malaria and dengue; as well as other major killers such as malnutrition and diarrhoea.

The carbon feedback cycle, used in the IPCC models, is shown as invalid for low-emissions scenarios and an alternative carbon cycle reduces the temperature response for the ERC considerably compared to the IPCC predictions. Within the last 1000 years, there are two extensive periods where temperatures were relatively warmer (the Medieval Warm Period) or cooler (the Little Ice Age).

Since anthropogenic forcing is believed to have been small then, it is assumed that these changes were due to natural factors. The change, however, is unrelated to global warming, the increase in the average temperature of the earth's atmosphere. Rather, they found, it's a function of the lesser-known phenomenon of local warming.

In the 1990s, global temperatures increased more quickly than in earlier decades, leading to claims that global warming had accelerated. In the past 10 years the temperature rise has slowed, leading to opposing claims. Atmospheric scientists generally agree that as carbon dioxide levels increase there is a law of "diminishing returns" - or more properly "diminishing effects" - and that ongoing increases in CO2 concentration do not generate proportional increases in temperature.

The common analogy is painting over window glass. If current fossil-fuel-consumption trends continue, average surface temperatures could rise by as much as 6.4 degrees by 2100, according to the Intergovernmental Panel on Climate Change. Even under the IPCC's most optimistic scenario, temperatures will still rise by 1.1-2.9 degrees before century's end.
