Control global warming reading answers

Is it climate change, global warming, or global climate crisis? Each of these terms refers to the same thing—the fact that the average temperature of the Earth’s atmosphere is rising. As the temperature rises, various impacts are changing aspects of our climate—hotter summers, As these impacts grow in frequency and severity, they will—and in many cases already have—create crises for people and nature around the world. If unchecked, these impacts will spread and worsen with more animal extinction and Whatever you choose to call it, the most important thing is that we act to stop it. Is climate change caused by humans? Yes, over 97% of scientist agree that humans cause climate change. Humanity’s accelerated burning of fossil fuels and deforestation ( Scientists have known for centuries that gases in Earth’s atmosphere like carbon dioxide and methane act as a greenhouse, preventing a certain amount of heat radiation from escaping back to space. The more carbon dioxide in the atmosphere, the warmer it gets. Over Earth’s history, carbon dioxide levels fluctuate due to volcanic activity or the carbon cycle (animals and bacteria breathe in oxygen and breathe out carbon dioxide while plants do the opposite). However, the rises in temperature and carbon dioxide levels we’ve seen in the past century are extreme and are accelerating. The rate of carbon emissions are the highest they’ve been in 66 million years and the amount of warming in the coming decades is expected to be 250 time...

Global Warming in New Zealand For many environmentalists, the world seems to be getting warmer. As the nearest country of South Polar Region, New Zealand has maintained an upward trend in its average temperature in the past few years. However, the temperature in New Zealand will go up 4°C in the next century while the polar region will go up more than 6°C. The different pictures of temperature stem from its surrounding ocean which acts like the air conditioner. Thus, New Zealand is comparatively fortunate. Scientifically speaking, this temperature phenomenon in New Zealand originated from what researchers call “SAM” (Southern Annular Mode), which refers to the wind belt that circles the Southern Oceans including New Zealand and Antarctica. Yet recent work has revealed that changes in SAM in New Zealand have resulted in a weakening of moisture during the summer, and more rainfall in other seasons. A bigger problem may turn out to be heavier droughts for agricultural activities because of more water loss from soil, resulting in poorer harvest before winter when the rainfall arrives too late to rescue. Among all the calamities posed be drought, moisture deficit ranks the first. Moisture deficit is the gap between the water plants need during the growing season and the water the earth can offer. Measures of moisture deficit were at their highest since the 1970s in New Zealand. Meanwhile, ecological analyses clearly show moisture deficit is imposed at different growth stage of ...

Forego Fossil Fuels—The first challenge is eliminating the Oil is the lubricant of the global economy, hidden inside such ubiquitous items as plastic and corn, and fundamental to the transportation of both consumers and goods. Coal is the substrate, So try to employ alternatives when possible—plant-derived plastics, biodiesel, wind power—and to invest in the change, be it by divesting from oil stocks or investing in companies practicing carbon capture and storage. Infrastructure Upgrade—Buildings worldwide contribute around one third of all greenhouse gas emissions (43 percent in the U.S. alone), even though Of course, it takes a lot of cement, a major source of greenhouse gas emissions, to construct new buildings and roads. The U.S. alone contributed 50.7 million metric tons of carbon dioxide to the atmosphere in 2005 from cement production, which requires heating limestone and other ingredients to 1,450 degrees Celsius (2,642 degrees Fahrenheit). Mining copper and other elements needed for electrical wiring and transmission also causes globe-warming pollution. But energy-efficient buildings and Move Closer to Work—Transportation is the second leading source of greenhouse gas emissions in the U.S. (burning a single gallon of gasoline produces 20 pounds of CO 2). But it doesn't have to be that way. One way to dramatically curtail transportation fuel needs is to move closer to work, use mass transit, or switch to walking, Cutting down on long-distance travel would also help...
