Question

Where do you think global warming has had a change on the environment?

Answer 1

The best information I know on that is here:

http://www.ipcc.ch/SPM6avr07.pdf

Sample:

"Based on growing evidence, there is high confidence that the following types of hydrological systems are being affected around the world:

• increased run-off and earlier spring peak discharge in many glacier- and snow-fed rivers [1.3];

• warming of lakes and rivers in many regions, with effects on thermal structure and water quality

[1.3].

There is very high confidence, based on more evidence from a wider range of species, that recent warming is strongly affecting terrestrial biological systems, including such changes as:

• earlier timing of spring events, such as leaf-unfolding, bird migration and egg-laying [1.3];

• poleward and upward shifts in ranges in plant and animal species [1.3, 8.2, 14.2].

Based on satellite observations since the early 1980s, there is high confidence that there has been a trend in many regions towards earlier ‘greening’5 of vegetation in the spring linked to longer thermal growing seasons due to recent warming. [1.3, 14.2]

There is high confidence, based on substantial new evidence, that observed changes in marine and freshwater biological systems are associated with rising water temperatures, as well as related changes in ice cover,

salinity, oxygen levels and circulation [1.3]. These include:

• shifts in ranges and changes in algal, plankton and fish abundance in high-latitude oceans [1.3];

• increases in algal and zooplankton abundance in high-latitude and high-altitude lakes [1.3];

• range changes and earlier migrations of fish in rivers [1.3].

The uptake of anthropogenic carbon since 1750 has led to the ocean becoming more acidic with an average decrease in pH of 0.1 units [IPCC Working Group I Fourth Assessment]. However, the effects of observed ocean acidification on the marine biosphere are as yet undocumented."

Answer 2

From personal experience I can say that developing , third world countries in tropical region have been the worst hit by pollution and global warming.

Temperatures here are increasing every summer and now its really hot combined with pollution the effect is disastrous.

The rainfall is pretty erratic and a lot of plant and animal species have been lost due to deforestration.

The temparature rise and irregular rainfall is the most easiest thing to note.

Answer 3

so far only the polar ice caps.

Answer 4

antartica because its cold up here
