By 2010, with 111 countries surveyed, Gallup determined that there had been a substantial decrease since 2007–2008 in the number of Americans and Europeans who viewed global warming as a serious threat. In the US, just a little over half the population (53%) viewed it as a serious concern for either themselves or their families; this was 10 points below the 2008 poll (63%). Latin America had the biggest rise in concern: 73% said global warming was a serious threat to their families.[247] This global poll also found that people were more likely to attribute global warming to human activities than to natural causes, except in the US where nearly half (47%) of the population attributed global warming to natural causes.
The global warming problem came to international public attention in the late 1980s. Polling groups began to track opinions on the subject, at first mainly in the United States.[243]The longest consistent polling, by in the US, found relatively small deviations of 10% or so from 1998 to 2015 in opinion on the seriousness of global warming, but with increasing polarization between those concerned and those unconcerned.
In 2009 conducted a study identifying global warming's 'Six Americas'. The report identifies six audiences with different opinions about global warning: The alarmed (18%), the concerned (33%), the cautious (19%), the disengaged (12%), the doubtful (11%) and the dismissive (7%). The alarmed and concerned make out the largest percentage and think something should be done about global warming. The cautious, disengaged and doubtful are less likely to take action. The dismissive are convinced global warming is not happening. These audiences can be used to define the best approaches for environmental action. The theory of the 'Six Americas' is also used for marketing purposes.
The first major worldwide poll, conducted by Gallup in 2008–2009 in 127 countries, found that some 62% of people worldwide said they knew about global warming. In the advanced countries of North America, Europe and Japan, 90% or more knew about it (97% in the U.S., 99% in Japan); in , especially in Africa, fewer than a quarter knew about it, although many had noticed local weather changes. Among those who knew about global warming, there was a wide variation between nations in belief that the warming was a result of human activities.
Q: What causes global warming?
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 earth’s surface. Normally, this radiation would escape into space—but these pollutants, which can last for years to centuries in the atmosphere, trap the heat and cause the planet to get hotter. That's what's known as the greenhouse effect.
Fortunately, state leaders—including itself—recognize 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 helpin which saw an increase in sales for 2017 over 2016 too, despite federal efforts to derail it. In 2016, wind employment grew by 32 percent and solar jobs increased by 25 percent.
Globally, at the United Nations Conference on Climate Change in Paris, 195 countries—including the United States, at the time—agreed to pollution-cutting provisions with a goal of preventing the average global temperature from rising more than 1.5 degrees Celsius above preindustrial times. (Scientists say we must stay below a two-degree increase to avoid catastrophic climate impacts.)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 emissions. Beginning in 2023, they will also have to publicly report their progress.hile in 2017, President Trump announced the country’s withdrawal from the Paris climate agreement and to eliminate “harmful and unnecessary policies such as the Climate Action Plan,” Americans are forging ahead without him. Through initiatives like the United States Climate Alliance, the Regional Greenhouse Gas Initiative, We Are Still In, and Climate Mayors, state, business, and local leaders have pledged to honor and uphold the goals of the Paris Agreement. More than 25 cities in 17 states, with populations totaling more than 5 million have that will enable them to get 100 percent of their electricity from renewable sources like wind and solar.
Q: Is global warming too big of a problem for me to help tackle?
A: Wonderin? 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 government’s Energy Star label; they meet a higher standard for energy efficiency than the minimum federal requirements. When you buy a car, look for one with the highest gas mileage and lowest emissions. You can also reduce your emissions by taking public transportation or carpooling when possible.
