In many regions, heat waves are becoming longer and more frequent.
Major commercial fishing could be destroyed by ocean acidification.
Agricultural losses are a result of the floods.
Seasonal timing is shifting.
Sea level rise will cause an increase in expenses.
More intense storms are causing more property loss and loss of life.
Ocean acidification is starting to affect marine life and farmers and foresters are struggling with altered growing seasons.
Crop yields are likely to fall in the tropics.
The forest is being altered by fire and pests.
There will be losses of food, water, and services due to the impact of biodiversity.
Water supplies to millions will be affected by the melting of mountain glaciers.
Economic costs will outweigh benefits.
The World Meteorological surface temperature, precipitation patterns, snow and ice Organization, the Environment Programme, and the former U.S. Vice President Al Gore were awarded the Nobel Peace Prize.
Future changes in these phe are predicted by its work in telling the world of the trends and impacts of nomena after considering a range of potential climate change scenarios.
A summary of thousands of scien society.
This report documents observed trends in response to strategies we might pursue.
Scientists study system, time is continuous and spatial effects reach down to climate today, and models are indispensable.
Predicting what conditions will not have enough computer power is vital for our society because climate models can't be so detailed.
Divide time into periods and divide the Earth's surface into cells or boxes to approximate reality.
The grid boxes are arrayed in a three-dimensional layer data-rich graphs and charts that show latitude and longitude.
The better the model is, the better it will be at predicting results when they put region by region.
Climate models already strain the ematical equations because of a long series of math puting power needed.
There are factors that affect climate.
Upwelling and atmosphere and ocean components were calledcoupled models.
Today's complex general circulation models share the acronym GCM.
Addingthropogenic factors can be done.
The major human influence on climate is our emission of greenhouse gases, and modelers need to select values to enter for future emissions if they want to predict future climate.
Depending on the scenario, they will run their simulations multiple times with different emission rates.
There are differences between the results from different scenarios.
You can see the results in Figure 18.26
There are figures that show the results of different models.
The best summary of each model is presented in the assessment reports.
Researchers constantly test and evaluate their models.
Incorporating what is learned from new research is one way they improve them.
Predicting future climate conditions will become more precise and accurate as their work proceeds.
The grid boxes represent land, air, or water and interact with each other through the flow of materials and energy.

The United States: The third national climate assessment has been compared by a number of studies.
Each decade has been accessible online at the IPCC's website.
If you were born after 1976, scientists around the world continue to monitor, model, and analyze our changing climate.
If you were born after 1985, you have never even been faster than before, because new research is being completed in response to the age global temperatures lower than the 20th century.
It is enough to cause both increases in air temperature over land and many other impacts because of the rapid change.
The average from 1991 to 2012 is compared to the average from 1901 to 1960.
