The Earth's climate has changed throughout history. Just in the last 650,000 years there have been seven cycles of glacial advance ar etreat, with the abrupt end of the last ice age about 7,000 years ago marking the beginning of the modern climate era and of human Civilization. Most of these climate changes are attributed to very small variations in Earth's orbit that change the amount of solar ene our planet receives.

The warming trends discussed in the Case Study are most pronounced at the equator, where sunlight is most direct. What would you predict the effect of global warming to be nearer the poles, where temperatures are lower and there is less sunlight?
Are the climatic changes we are currently experiencing "the new normal". Explain.
Which of the following statements about atmospheric carbon dioxide levels is correct? For about 800,000 years prior to human influence it varied between 180 and 300 ppm and is now above 410 ppm. For about 800,000 years prior to human influence it never exceeded 200 ppm. Its rate of increase in the past century is greater than any seen in the ice core record. Both 1 & 3
Climate is the result of a variety of global processes. What of the following is a climatological driver? rotation of Earth hydrosphere properties oceanic currents concertation of sun irradiances all of the above
Which of the following is NOT true about climate change? a. Today’s climatic warming particularly the warming since the mid-20th century is occurring much faster than ever before and cannot be explained by natural causes alone. b. Humans more specifically, the greenhouse gas (GHG) emissions we generate are the leading cause of the earth’s rapidly changing climate. c. The burning of fossil fuels like coal, oil, and gas for electricity, heat, and transportation is the primary source of natural cause of climate change. d. Activities like agriculture and road construction can change the reflectivity of the earth’s surface, leading to local warming or cooling, too.
What is the diffe rence between climate change detection and climate change attribution? O attribution is a change in climate relative to some baseline condition, and detection focuses on the cause of the change in climate climate change has not been detected, but it has been attributed to human activities climate change has been dete cted, but it has not been attributed to human activities detection is a change in climate relative to some baseline condition, and attribution focuses on the cause of the change in climate climate change has neither been detected nor attributed to human activities

Recent research has suggested that globalwarming is contributing to the increased fre-quency and severity of El Niño events. Thiscan cause severe drought in India andAfrica, as well as greatly reduce fish catch inparts of the Southern Hemisphere. Shouldthe responsibility for decreasing greenhousegas emissions be greater for more-developedcountries (MDCs) because they produce agreater amount of greenhouse gases percapita than less-developed countries(LDCs), even though El Niños have moresevere consequences for LDCs? Aside from the recent increases in gasolineprices, would you consider buying a morefuel-efficient car or spend more on planeflights to purchase "carbon credits" to doyour part in decreasing the emission ofgreenhouse gases such as carbon dioxide?Why or why not?
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.
Aside from the rise in mean temperature and CO2 levels, what are some other pieces of evidence from global warming? Discuss.
