The InterGovernmental Panel on Climate Change (IPCC)'s 4th Assessment Report (2007) projects that we will probably reach 4°C warming above pre-industrial age levels by 2100. We will pass the 'danger limit' of 2°C warming by 2050.
Sea levels are also predicted to rise at an accelerated rate. Observed sea levels are actually tracking at the upper range of the IPCC projections of 3 mm per year. When accelerating ice loss from Greenland and Antarctica are factored in to the projections, the estimated sea level rise by 2100 is between 75 cm to 2 meters.
Answer (pessimistic)
Within the next 100 years a significant portion of ice near the Arctic Circle will melt, particularly Greenland Ice, contributing to seal level rise eventually reaching as high as 20 feet. This means that many coastal areas will flood.
The US National Research Council estimates sea level rise will only be 2 to 7 feet by 2100, implying most of the Greenland ice will not have melted by the end of this century. Most scientists are convinced the data is sufficiently robust to conclude the present warming trend will continue or accelerate without substantial modifications in human practices and behavior.
The IPCC notes that the 3.3 mm/year measured rate of sea level rise is much faster than originally predicted.
What else can I help you with?
Is both global environment and global warming is same?
Not quite, though they are very closely connected. Global warming is the warming of the earth. This is causing climate change, which is the many different changes in climate that are beginning to happen.
Where did climate change all begin?
Climate change began as a result of human activities that release greenhouse gases into the atmosphere, such as burning fossil fuels and deforestation. These gases trap heat in the Earth's atmosphere, leading to a warming trend that results in changes to the climate system. Climate change has been exacerbated by industrialization and the increase in carbon dioxide levels since the mid-20th century.
What are the major topics of climate change?
The major topics of climate change include global warming, rising sea levels, extreme weather events, ocean acidification, and loss of biodiversity. These issues are interconnected and have widespread impacts on ecosystems, communities, and economies around the world. Addressing these topics requires global cooperation and action to mitigate the effects of climate change.
What do you think might happen if global climate chane affected the global conveyor belt?
ice age!
Do all scientist agree that global climate change will happen rapidly?
There is most certainly NOT consensus amoung scientists about the speed of global climate change - nor is there even consensus as to what would constitute a sufficient change to be considered a "global climate change". How much melting of ice caps is necessary before it is considered a major change? How much change in average temperature? 0.5 °F? 1 °F? 2 °F? 10 °F? Over what length of time do you average? 5 years? 10 years? 100 years? some models suggest a shift over 10 years. Others suggest a change taking more than 100 years.

Can an abrupt climate change happen?
yes

What would happen to global climate if the sun emitted more energy?
The earth will melt
What would happen to the global climate if there were a dramatic decrease in greenhouse gases trapped in the atmosphere?
A dramatic decrease in greenhouse gases in the atmosphere would lead to a reduction in the greenhouse effect, resulting in a cooler global climate. This could potentially slow down or reverse some of the current impacts of climate change such as global warming, rising sea levels, and extreme weather events. However, it is important to note that other factors also influence global climate, so the impact would not be immediate or completely predictable.
Does increasing sea level cause an increase in precipitation?
No, not necessarily. Global warming, which is causing increasing sea levels, is also responsible for climate change. Climate change may mean more rainfall in some areas, and less in others. It is not possible yet to forecast where or how much this will happen.
What are the things that could happen in global warming?
supposedly the atmosphere will burn up leaving us with no oxygen. another theory is that the climate will change and areas all over the equator will freeze.
Why is global warming now called climate change?
It is still called Global Warming, but many people are now talking about Climate Change.Global warming is the way the world is warming (through burning fossil fuels (coal, oil and natural gas) and deforestation). But global warming is CAUSING Climate change.
What would happen if Salt Lake City decreased 10 degrees?
In temperature? Probably more people might move there seeking a cooler climate. But since that is not likely to happen anytime soon, probably nothing will come of any kind of temperature change for this city.
