Textbook Question
Chapter 7, Problem 17TYK
Most scientific experts agree that climate change is already occurring and has potentially catastrophic consequences for all of life on Earth. The Paris climate talks of 2015 have, for the first time, reached a global consensus on the need to reduce greenhouse gas emissions. Go online and research the main agreements reached in this historic global climate accord. What roles do you think scientists, politicians, and citizens will need to play to cut emissions and limit global warming?

Students have asked these similar questions
Why is carbon dioxide the focus of so much attention regarding climate change? What are the main sources of carbon dioxide in the atmosphere and what can we do to reduce the amount of carbon dioxide in the atmosphere? Bring into your discussion the carbon cycle, a discussion of Venus and Mercury, the evidence for human impact on carbon dioxide levels in the atmosphere and its impact on climate (refer to any graphs you need to), and ways in which scientists have recommended limiting climate change.
How can you, as a climate change scientist develop a research proposal to reduce CO2 levels to positively impact climate change?
Explain why you agree or disagree with
at least 90% the world's climate
scientists that (a) climate change is
happening now, (b) human activities
play an important role in this climate
change, and (c) human actions can slow
down the rate of climate change and
avert or delay its projected harmful
environmental, health, and economic
effects.

- Understanding the scale and impact of climate change is crucial for our survival and the health of our planet. As highlighted in the article “Climate emergency is the biggest health crisis of our time - bigger than Covid” by Pascal Soriot, the climate crisis is not only a threat to the environment but also to global health, making it even more urgent than the COVID-19 pandemic. The article stresses that immediate and radical action is necessary to reduce greenhouse gas emissions, as the effects of global heating are already causing irreversible damage to both ecosystems and human health. The climate crisis has far-reaching consequences, including rising temperatures, which are linked to an increase in heat-related deaths. Soriot states that heat-related deaths are expected to triple by 2050, and already, 7 million people die annually due to air pollution. This staggering toll exceeds the death count from the entire COVID-19 pandemic. Moreover, chronic diseases such as cancer are being…arrow_forwardMost biologists and climatologists agree that the earth is warming, why do people disregard the evidence for global warming?
