- Global warming has become one of the worlds most co mplicated and major issues
- Emissions rose 5.9 percent in 2010, according to the Global Carbon Project
- For almost two decades, the United Nations has sponsored annual global talks united states framwork convention of climate change
- global emisions of carbon dioxide jumped by the largest amount in the year 2010
- some scientists say our food and water supply is at risk
- Global warming threatens our everyday needs
- some impacts are record high temperatures, melting glaciers and servere flooding and droughts
- scientists say the earth is almost at the point where global warming is unreverseable
- scientists say humans are to blame
- scientists say that global warming is what caused the drought in Ethiopia which killed millions
- The world mostly agrees that something needs to be done about global warming and climate change
- The United States plus a few other countries, and many large corporations, have opposed climate change treaties seemingly afraid of profit impacts if they have to make substantial changes to how they do business.
- a few influential companies and organizations are still attempting to undermine climate change action and concerns.
- Industrialized nations have emitted far more greenhouse gas emissions (even if some developing nations are only now increasing theirs);
- Rich countries therefore face the biggest responsibility and burden for action to address climate change
- Rich countries therefore must support developing nations adapt—through financing and technology transfer
- rich nations have done very little within the Kyoto protocol to reduce emissions by any meaningful amount
- starting a program that will address short-lived pollutants like soot
- methane and hydrofluorocarbons that have an outsize influence on global warming, accounting for 30 to 40 percent of global warming.
- Soot from diesel exhausts and the burning of wood, agricultural waste and dung for heating and cooking causes an estimated two million premature deaths a year, particularly in the poorest countries.
- Climate change is a problem that is affecting people and the environment. Greater energy efficiency and new technologies hold promise for reducing greenhouse gases and solving this global challenge.
- Climate change will have a significant impact on the sustainability of water supplies in the coming decades
- he study found that more than 1,100 counties -- one-third of all counties in the lower 48 -- will face higher risks of water shortages by mid-century as the result of global warming. More than 400 of these counties will face extremely high risks of water shortages.
- Solving global warming will improve our lives by cleaning up air pollution while investing in clean energy, green jobs and smart energy solutions that get the U.S. economy moving again.
- In 2011, record-breaking extreme events occurred in each of the 50 states, and the frequency and intensity of some extreme events is likely to worsen with climate change.
- Climate change is one of the most serious public health threats facing the nation
- Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studies.
- The rate of warming is increasing. The 20th century's last two decades were the hottest in 400 years and possibly the warmest for several millennia, according to a number of climate studies. And the United Nations' Intergovernmental Panel on Climate Change (IPCC) reports that 11 of the past 12 years are among the dozen warmest since 1850.
- The Arctic is feeling the effects the most. Average temperatures in Alaska, western Canada, and eastern Russia have risen at twice the global average, according to the multinational Arctic Climate Impact Assessment report compiled between 2000 and 2004.
- Arctic ice is rapidly disappearing, and the region may have its first completely ice free summer by 2040 or earlier. polar bears and other creatures are already suffering from the sea-ice loss.
- Glaciers and mountain snows are rapidly melting—for example, Montana's glacier national park now has only 27 glaciers, versus 150 in 1910. In the Northern Hemisphere, thaws also come a week earlier in spring and freezes begin a week later.
- Humans are pouring carbon dioxide into the atmosphere much faster then plants and animals can absorb it
- Some experts point out that natural cycles in Earth's orbit can alter the planet's exposure to sunlight, which may explain the current trend. Earth has indeed experienced warming and cooling cycles roughly every hundred thousand years due to these orbital shifts, but such changes have occurred over the span of several centuries. Today's changes have taken place over the past hundred years or less.
- Sea level could rise between 7 and 23 inches (18 to 59 centimeters) by century's end, the IPCC's February 2007 report projects. Rises of just 4 inches (10 centimeters) could flood many South Seas islands and swamp large parts of Southeast Asia.
- Glaciers around the world could melt, causing sea levels to rise while creating water shortages in regions dependent on runoff for fresh water.
- Strong hurricanes, droughts, heat waves, wildfires, and other natural disasters may become commonplace in many parts of the world. The growth of deserts may also cause food shortages in many places.
- The ocean's circulation system, known as the ocean conveyor belt, could be permanently altered, causing a mini ice age in western Europe and other rapid changes.
