6 天前 · Global warming, the phenomenon of rising average air temperatures near Earth’s surface over the past 100 to 200 years. Although Earth’s climate has been evolving since the dawn of geologic time, human activities since the Industrial Revolution have a growing influence over the pace and extent of climate change.

全球变暖 （台湾作 全球暖化），指的是在一段時間中， 地球 的 大气 和 海洋 因 溫室效應 而造成 溫度 上升的 氣候變化，為 公地悲劇 之一，而其所造成的 效應 稱之為 全球变暖效应。 在2013年， 政府间气候变化专门委员会 第五次评估报告认为，“人类影响极有可能是20世纪中叶以来观测到的变暖现象的主要原因。 ” [2] 人类的影响包括排放诸如 二氧化碳 、 甲烷 和 一氧化二氮 这样的 温室气体，鉴于人类活动在全球变暖中扮演主要角色，这种现象有时候被称为“人为全球变暖”或“人为气候变化”。 报告中的气候模型预测总结指出在21世纪，根据温室气体的排放量，全球表面温度有可能进一步上升0.3-1.7°C至2.6-4.8°C。
Global warming is the long-term heating of Earth’s surface observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. This term is not interchangeable with the term "climate change."

A: Here's a simple definition of global warming. (And yes, it's really happening.) Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history. And experts see the trend is accelerating: All but one of the 16 hottest years in NASAs 134-year record have occurred since 2000.
Climate change deniers have argued that there has been a pause or a slowdown in rising global temperatures, but several recent studies, including a 2015 paper published in the journal Science, have disproved this claim. And scientists say that unless we curb global-warming emissions, average U.S. temperatures could increase by up to 10 degrees Fahr...
A: Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earths surface. Normally, this radiation would escape into spacebut these pollutants, which can last for years to centuries in the atmosphere, trap the heat and ...
In the United States, the burning of fossil fuels to make electricity is the largest source of heat-trapping pollution, producing about two billion tons of CO2 every year. Coal-burning power plants are by far the biggest polluters. The countrys second-largest source of carbon pollution is the transportation sector, which generates about 1.7 billion...
The earths ocean temperatures are getting warmer, toowhich means that tropical storms can pick up more energy. So global warming could turn, say, a category 3 storm into a more dangerous category 4 storm. In fact, scientists have found that the frequency of North Atlantic hurricanes has increased since the early 1980s, as well as the number of stor...
Fortunately, state leadersincluding in car country itselfrecognize that clean transportation must remain a priority if we are to address the costly risks of climate change and protect public health. And regional efforts around the country are helping to boost the electric car market, which saw an increase in sales for 2017 over 2016. Our clean ener...
To help make the deal happen, the Obama administration pledged $3 billion to the Green Climate Fund, an international organization dedicated to helping poor countries adopt cleaner energy technologies. Under the terms of the Paris agreement, participating nations will meet every five years, starting in 2020, to revise their plans for cutting CO2 em...
Even better, a new initiative by former New York City mayor Michael Bloomberg gives the urban layer of this movement a boost. Hes asked mayors from the 100 most populous cities in the country to share their plans for making their buildings and transportation systems run cleaner and more efficiently. The 20 that show the greatest potential for cutti...
A: Wondering how to stop global warming? Reduce your own carbon footprint by following a few easy steps. Make conserving energy a part of your daily routine and your decisions as a consumer. When you shop for new appliances like refrigerators, washers, and dryers, look for products with the governments Energy Star label; they meet a higher standard...
