Some things just seem too momentous to keep in mind.
Alexander One of the main points of contention among scientists is what will happen to the planet as a result of global warming.
Some believe that the earth will actually benefit if the climate continues to grow warmer. Others insist that the opposite is true, saying that if the planet continues to heat up, the effects will be catastrophic.
NASA sums up these very different perspectives: Many see [global warming] as a harbinger of what is to come. If we don't curb our greenhouse gas emissions, then low-lying nations could be awash in seawater, rain and drought patterns across the world could change, hurricanes could become more frequent.
On the other hand, there are those, some of whom are scientists, who believe that global warming will result in little more than warmer winters and increased plant growth.
They point to the flaws in scientists' measurements, the complexity of the climate, and the uncertainty in the climate models used to predict climate change. They claim that attempting to lower greenhouse emissions may do more damage to the world economy and human society than any amount of global warming.
In truth, the future probably fits somewhere between these two scenarios. Models can be used to simulate temperature changes that occur from both natural and anthropogenic causes. Scientists enter data on different conditions, such as atmospheric concentrations of greenhouse gases, ocean currents, cloud cover, energy from the sun, and ocean circulation, as well as others.
Then, as they change and adjust the variables, they can simulate what might happen when actual climate conditions change. NASA compares climate models to the computer programs used by detectives to envision what This illustration mimics a computer model used to predict climate change.
The melting earth suggests global warming is a serious threat. A scientist explains a general circulation model generated by a supercomputer.
Scientists debate the value of computer model predictions. In the same way the detective programs are constructed on information about people's faces, climate models are constructed based on data that relate to the earth's climate.
There are many different types of climate models. The simplest models can be run on personal computers, and are designed to focus on one particular time frame, or to investigate a specific phenomenon.
The most sophisticated climate models are supercomputers known as general circulation models GCMs. Climate models have evolved from the same sort of computer programs that are used to make weather forecasts.The Main Causes of Global Warming: Global Warming is caused by the greenhouse effect in Earth's atmosphere.
The greenhouse effect is what keeps the planet warm enough for l ife. This worked. Putting Global Warming into Context: We are Ice Age Creatures Living on a Planet That Was Already Getting Warmer Before We Started Speeding Up the Process .
Modern Global Warming (MGW) is the change in climate that has been taking place from the coldest period of the Little Ice Age (LIA) to the present. It is characterized by a preponderance of warming periods over cooling periods, resulting in the warming of the planet, expansion of tropical areas.
Since the slowdown in surface warming over the last 15 years has been a popular topic recently, I thought I would show results for the lower tropospheric temperature (LT) compared to climate models calculated over the same atmospheric layers the satellites sense.

Ten years ago, Al Gore claimed we had 10 years to save the planet from global warming, as pointed out in this Communist BS (CBS News) report from early Unless drastic measures to reduce greenhouse gases are taken within the next 10 years, the world will reach a point of no return, Gore said.
