Concept explainers
Explain the reason for models of climate change report, the temperature and CO2 levels only for 100 years in the future. Explain the reason for not using models to predict 200 years into the future.
Explanation of Solution
In the middle of the 20th century, the scientists have established that the value of carbon dioxide and temperature rise is matched with the actual data of 1850, about 100 years prior to the climatic model. The scientists have also observed that the error in the measurement of carbon dioxide by the climatic model is lower till 1950.
Hence, the models of climate change report, the temperature and CO2 levels only for 100 years into the future in order to have minimum error in the result.
The climatic model is not used to predict 200 years into the future as the error associated with the corresponding result will be high, leading to inaccurate and wrong measurement of carbon dioxide and temperature measurements.

Presume you were born into a developing country. Your community’s health and prosperity are threatened by climate changes caused by anthropogenic CO2 emissions generated primarily by developed countries. This situation is so extreme that people in your community do not name their children until they live past 5 years old, since many die before that age. If you had a chance to talk to an engineer in a developed country, what would you say?arrow_forward

It is known that when a certain food product is packaged, the number of organisms present in the food is N, and after 30 days the number of organisms has grown to 100N. How many days will it take for the number of organisms to reach 200N?arrow_forwardPART 1: Reading: Read the text below. Then answer the questions that follow. (1) Around 45% of the UK's carbon dioxide emissions come from the energy people use every day - at home and when they travel. In order to generate that energy, fossil fuels (coal, oil, and gas) are burnt, and these produce greenhouse gases - in particular carbon dioxide (CO2). Car emissions are a major problem, but the truth is that more CO2 comes from the energy used at home. The average household creates around five and a half tonnes of CO2 a year, and it is that same CO2 which is changing the climate and damaging the environment. (2) CO2 and various other gases wrap the earth in an invisible blanket helping to prevent heat from escaping. Without this greenhouse effect, the average temperature on Earth would be around -18°C, compared with the current average of around +15°C. The composition of this blanket of gases has remained relatively constant for many thousands of years. However, since the industrial…arrow_forward
