Why can't scientists claim 100 percent accuracy when making predictions based on the global-warming climate model?

In science there is no 100% with the evidence provided the sun will come up tomorrow. they are 99.999999999% sure it will. But the sun could not come up tomorrow.
So as a rule science never gives out 100% at all. That is beside the point though.
The earth is 4.55 billion years old. Humans started to evolve away from primates 130,000 years ago. So we have only been on this earth for 1/35,000th of it's life span. We really don't know much about earth's natural cycles.
If the entire time the earth has been around was compressed into a single day. Humans would have been around for a maximum of 2.4 seconds. Imagine trying to predict the cycle of a day with 2.4 seconds.
If you took 2 seconds of the night, then you would assume it is always dark and cold. When day came around you would be quite shocked at how hot it is.
So in short. Science never gives out 100%'s and humans have been on the earth for such a short time it is very difficult to predict with any certainty what is going to happen.

∙ 9y agoIt is difficult to predict climate change because patterns are constantly changing. Scientists are certain that global warming is putting more heat (energy) into the atmosphere. This extra energy is used in weather events like storms.

∙ 13y agoOne of the problems with very early climate change models was the failure to allow for localised urban warming, so that when a temperature gauge, that was formerly in a rural setting, becomes surrounded by new suburbs it can provide a long term upward trend that has nothing to do with global warming. This problem has since been recognised and an appropriate allowance made in each such case.
The Berkeley Earth Surface Temperature project at the University of California, Berkeley, was launched by a Physics Professor, Richard Muller, a longtime critic of government-led climate studies, to address what he called "the legitimate concerns" of sceptics who believe global warming is exaggerated. But Professor Muller unexpectedly told a congressional hearing the work of the three principal groups that have analysed the temperature trends underlying climate science is "excellent ... We see a global warming trend that is very similar to that previously reported by the other groups." Professor Muller acknowledged that previous studies accounted for the urban effect. "Did such poor station quality exaggerate the estimates of global warming?" he asked in his written testimony. "We've studied this issue, and our preliminary answer is no."
Over the past two decades, three independent groups have used varying statistical methods and yet arrived at nearly identical conclusion that the planet's surface, on average, has warmed about 0.75 degree since the beginning of the twentieth century.

How do scientists calculate future climate changes predictions?
Scientists use complex computer models known as climate models to calculate future climate change predictions. These climate models simulate the Earth's climate system by incorporating data on greenhouse gas emissions, land use changes, and other factors that influence climate. By running these models with different scenarios and assumptions, scientists can predict how these changes will affect global temperature, precipitation patterns, sea level rise, and other climate variables in the future.
How do scientists learn about the climate in Antarctica thousands of years ago?
Ice cores are useful for scientists who want to learn about the climate in Antarctica thousands of years ago.
Why do scientists think that climate is changing?
Scientists can measure that the global temperature is rising. They know that rising temperatures will change the climate. Weather happens from day to day, but climate change takes longer, several years, or several decades before it becomes clear that it is happening. That is the situation now. Scientists know that rising temperatures will change the climate.
Why can you not be sure of what will happen in the future with climate change?
Because no one can foretell the future. Scientists use computer models to try and work out what will happen, and they have made various predictions. We know that rising temperatures will affect the climate, but there are many possibilities. Some places, like Europe, may even be colder if warm ocean currents like the Gulf Stream stop.
Do most scientists agree that there is conclusive evidence that carbon dioxide drives climate?
Yes, 97% of peer-reviewed climate scientists agree that there is conclusive proof that carbon dioxide is causing global warming, which is driving climate change.
Is it true or false that since climate is hard to study on a global scale scientists use computer models to make climate predictions?
true
Which is not a reason why scientists are limited in their ability to make predictions to climate change?
because scientist are payed by the government
Scientists study upper atmospheric conditions to?
Meteorologists study the upper atmospheric condition for the predictions of weather conditions, and the climate.

Scientists say that climate data from nine different countries indicate that every country will be hit with major climate changes during this century. How can scientists make such predictions?
Scientists observe data trends by observing temperatures, over long periods of time and observing related climatic changes associated with those trends, This includes winds, precipitation, cloud cover. The data is then incorporated into climate algorithms which calculated trends and impacts into the future. The predicted trends are verified as time passes to improve the algorithms to generated better trend data. This results in future estimations of climate change.
What type of scientist studies global warming?
Climate scientists and atmospheric scientists are the main experts studying global warming. There are many names for the different aspects of climate study.climatologist: scientists who study weather patterns and climate.meteorologist: scientists who study the weather and how it changes.oceanographers: scientists who study weather and climate based on what is happening in the world's oceans.biologists: scientists that study climate change based on how it is impacting animals.anthropologists: scientists who are studying people, and how climate change may affect our way of life as a civilized society
How is Hurricane Katrina related to global warming?
No single weather event can be attributed with certainty to global warming. All climate scientists can say is that the icreased intensity of hurricanes and tornado events is consistent with predictions about global warming. Scientists simply do not know whether global warming influenced the intensity or duration of Hurricane Katrina.
Why do climate scientists believe climate change is real and is of concern?
Climate scientists believe climate change is real and is of concern because they understand the science involved and the factors that contribute to the climate, what controls it, and what is happening that makes the climate change. They also see and understand how the climate is changing and why it is happening.
How far in advance can a heat wave be predicted?
Heat waves can be predicted up to around one to two weeks in advance using climate models and weather patterns. However, the accuracy of these predictions decreases the further out they are made, so shorter-term forecasts are typically more reliable. Local weather agencies and meteorologists can provide more specific and up-to-date predictions as the event approaches.
What are predictions for climate change based on?
i'm guessing weather reports or analysis of acid rain
What do you call a person who studies Global warming?

Do scientists make up the earth's changing climate?
No, scientists neither create the climate, nor imagine the changes occurring within it. Instead, they measure the change.Some climate scientists are financially or politically motivated (generally by the fossil fuel industry) to find no correlation between human activity and climate change. Most scientists, however, lack any financial incentive to find one way or the other. Claims climate scientists not funded by the fossil fuel industry are financially invested in the outcomes of their research are simply false. In fact, climate scientists have an incentive to overturn the current findings. This is how scientists win fame and acclaim--NOT by upholding established findings.
