What does fossil evidence show about Earth's climate?
The fossil evidence shows that the Earth's climate before had high levels of carbon dioxide. The plants that evolved consumed this carbon dioxide out of the air and formed oxygen, coal, limestone, and other fuels.
Do scientists think people affect climate change?
Yes climate scientists think that people are affecting climate change mostly from carbon emissions (from burning fossil fuels) and because we have destroyed the forests of the world that used to absorb carbon dioxide from the atmosphere.
What do scientists expect to happen to the climate of the earth if the carbon dioxide levels continues to rise?
Scientists expect that if carbon dioxide levels continue to rise, it will lead to an increase in global temperatures, resulting in more frequent and severe heatwaves, wildfires, droughts, and extreme weather events. This can also lead to rising sea levels, loss of biodiversity, and disruptions to ecosystems and agriculture.
Which increase in atmospheric carbon dioxide contributes to global climate change?
Any increase in atmospheric carbon dioxide contributes to global climate change.
What are facts scientists have learned about earth's climate from core samples?
Scientists have learned about past climate conditions by studying ice core samples, including temperature changes, carbon dioxide levels, and atmospheric composition. They can also study the frequency and impact of natural events like volcanic eruptions and shifts in ocean currents by analyzing core samples. Overall, ice core data provides valuable insights into Earth's climate history and helps inform our understanding of future climate change.
What does fossil evidence show about Earth's climate?
The fossil evidence shows that the Earth's climate before had high levels of carbon dioxide. The plants that evolved consumed this carbon dioxide out of the air and formed oxygen, coal, limestone, and other fuels.
Why do people believe that global warming is happening?
They believe the scientists have clear evidence that it is happening.They believe the governments who have signed up to reduce carbon dioxide emissions.They see the evidence with their own eyes that the climate is changing, glaciers are melting, the Arctic is ice free for longer summers each year.
What do scientists expect to happen to the climate of the earth if carbon dioxide levels continues to rise?
The climate will become very unusually and we will have stormy climates. It will also be warm at times.
If a speaker wanted to support her thesis that the use of cars has had an effect on the climate would be the best evidence to use?
The best evidence to support this thesis would be scientific data and research studies showing the correlation between car emissions and climate change. This can include statistics on carbon dioxide levels in the atmosphere, temperature trends, and the impact of vehicle exhaust on greenhouse gas concentrations. Additionally, citing expert opinions from climate scientists and environmental organizations would strengthen the argument.
Ice samples from glaciers provide evidence that today's atmosphere contains more carbon dioxide than ancient atmosphere on earth did.why id this increase in carbon dioxide a concern to scientists?
It is of no concern to scientists - its just data. However, it is a concern to the human beings who are also scientists since their environment is getting fouled up.
Why do some scientists theorize that global warming not be the result of increases in atmospheric carbon dioxide?
Some scientists theorize that global warming might not be solely due to increases in atmospheric carbon dioxide because there are other factors that can also influence the Earth's climate, such as changes in solar radiation, volcanic eruptions, and natural climate variability. They argue that a combination of these factors could be contributing to global warming in addition to carbon dioxide emissions.
Can human activity change the climate?
Yes, the burning of fossil fuels for the past 200 years is accepted by most climate scientists as adding additional greenhouse gases (carbon dioxide) to the atmosphere. This is causing a global warming, which is making the climate change.
What is the significance of the absorption spectrum of carbon dioxide in the context of climate change?
The absorption spectrum of carbon dioxide is significant in the context of climate change because it shows how much heat energy the gas can trap in the Earth's atmosphere. This trapping of heat, known as the greenhouse effect, contributes to global warming and climate change. Understanding the absorption spectrum helps scientists predict how increasing levels of carbon dioxide in the atmosphere will impact the Earth's temperature and climate.
Do scientists think people affect climate change?
Yes climate scientists think that people are affecting climate change mostly from carbon emissions (from burning fossil fuels) and because we have destroyed the forests of the world that used to absorb carbon dioxide from the atmosphere.
Who supports the view that global warming is not happening?
People who don't believe in science. Climate scientists around the world, 97% of them, agree that global warming is happening, and it is being caused by the human activities of deforestation and the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide. Climate scientists look at climate, not weather, which varies from year to year, and the climate trends have been warming since the beginning of the Industrial Revolution. Another View: The fact is, there are many scientists that say the planet is not warming, and recent evidence backs them up. The last two winters have been brutal in North America, and the last two summers relatively mild.
Why are scientists concerned about carbon dioxide released from burning fossil fuels like petrol?
Scientists are concerned about carbon dioxide released from burning fossil fuels because it is a greenhouse gas that contributes to global warming and climate change. Excess carbon dioxide in the atmosphere traps heat, leading to rising global temperatures, melting ice caps, more extreme weather events, and other environmental impacts. Reducing carbon dioxide emissions is essential to combat climate change and its associated risks.
What do scientists expect to happen to the climate of the earth if the carbon dioxide levels continues to rise?
Scientists expect that if carbon dioxide levels continue to rise, it will lead to an increase in global temperatures, resulting in more frequent and severe heatwaves, wildfires, droughts, and extreme weather events. This can also lead to rising sea levels, loss of biodiversity, and disruptions to ecosystems and agriculture.
