Top 11 Warmest Years On Record Have All Been In Last 13 Years

http://www.sciencedaily.com/releases/200...

ScienceDaily (Dec. 13, 2007) — The decade of 1998-2007 is the warmest on record, according to data sources obtained by the World Meteorological Organization (WMO). The global mean surface temperature for 2007 is currently estimated at 0.41°C/0.74°F above the 1961-1990 annual average of 14.00°C/57.20°F...

...Since the start of the 20th century, the global average surface temperature has risen by 0.74°C. But this rise has not been continuous. The linear warming trend over the last 50 years (0.13°C per decade) is nearly twice that for the last 100 years...

...2007 global temperatures have been averaged separately for both hemispheres. Surface temperatures for the northern hemisphere are likely to be the second warmest on record, at 0.63°C above the 30-year mean (1961-90) of 14.6°C/58.3°F. The southern hemisphere temperature is 0.20°C higher than the 30-year average of 13.4°C/56.1°F, making it the ninth warmest in the instrumental record since 1850.

January 2007 was the warmest January in the global average temperature record at 12.7°C/54.9°F, compared to the 1961-1990 January long-term average of 12.1°C/53.8°F...

Answer 3

there is evidence that global warming is not a new phenomenon. I don't think it's a hoax, but maybe it's not as terrible as we think. maybe it's just the way this world operates. just maybe.

Answer 4

the global warming myth HAS been propagated and politicized. its become political, because politicians are going to make decisions that affect us all, and if they make decisions based on erroneous data, that will be costly to people around the world.

Look, 2 key measuring sticks (Sea Ice, and Polar Bears) are both doing well. we are seeing the highest levels of sea ice, almost ever (2nd highest levels since we've started recording it), and the Polar Bear Populations are higher than they have ever been in modern times (5000 in 1972, to 25000 today). Even the 2nd link i provided agrees with current population levels, but the site INSISTS that the polar bear populations are DECLINING, despite the fact that their population has exploded over the last 30 years. do some simple research for yourself, you'll see through the rhetoric.

Answer 5

Yes it is getting warmer, the earth is just getting back to its natural warmer state.

Sun spots are the major reason for climate change on earth.

Answer 6

The Earth's climate has changed many times during the planet's history, with events ranging from ice ages to long periods of warmth. Historically, natural factors such as volcanic eruptions, changes in the Earth's orbit, and the amount of energy released from the Sun have affected the Earth's climate. Beginning late in the 18th century, human activities associated with the Industrial Revolution have also changed the composition of the atmosphere and therefore very likely are influencing the Earth's climate.

For over the past 200 years, the burning of fossil fuels, such as coal and oil, and deforestation have caused the concentrations of heat-trapping "greenhouse gases" to increase significantly in our atmosphere. These gases prevent heat from escaping to space, somewhat like the glass panels of a greenhouse.

Greenhouse gases are necessary to life as we know it, because they keep the planet's surface warmer than it otherwise would be. But, as the concentrations of these gases continue to increase in the atmosphere, the Earth's temperature is climbing above past levels. According to NOAA and NASA data, the Earth's average surface temperature has increased by about 1.2 to 1.4ºF in the last 100 years. The eight warmest years on record (since 1850) have all occurred since 1998, with the warmest year being 2005. Most of the warming in recent decades is very likely the result of human activities. Other aspects of the climate are also changing such as rainfall patterns, snow and ice cover, and sea level.

If greenhouse gases continue to increase, climate models predict that the average temperature at the Earth's surface could increase from 3.2 to 7.2ºF above 1990 levels by the end of this century. Scientists are certain that human activities are changing the composition of the atmosphere, and that increasing the concentration of greenhouse gases will change the planet's climate. But they are not sure by how much it will change, at what rate it will change, or what the exact effects will be.

U.S. Climate Policy

The United States government has established a comprehensive policy to address climate change. This policy has three basic components:

Slowing the growth of emissions

Strengthening science, technology and institutions

Enhancing international cooperation

To implement its climate policy, the Federal government is using voluntary and incentive-based programs to reduce emissions and has established programs to promote climate technology and science. This strategy incorporates know-how from many federal agencies and harnesses the power of the private sector.

In February 2002, the United States announced a comprehensive strategy to reduce the greenhouse gas intensity of the American economy by 18 percent over the 10-year period from 2002 to 2012. Greenhouse gas intensity is a measurement of greenhouse gas emissions per unit of economic activity. Meeting this commitment will prevent the release of more than 100 million metric tons of carbon-equivalent emissions to the atmosphere (annually) by 2012 and more than 500 million metric tons (cumulatively) between 2002 and 2012.

EPA plays a significant role in helping the Federal government reach the United States' intensity goal. EPA has many current and near-term initiatives that encourage voluntary reductions from a variety of stakeholders. Initiatives, such as ENERGY STAR, Climate Leaders, and our Methane Voluntary Programs, encourage emission reductions from large corporations, consumers, industrial and commercial buildings, and many major industrial sectors.

Greenhouse Gas Emissions

In the U.S., our energy-related activities account for three-quarters of our human-generated greenhouse gas emissions, mostly in the form of carbon dioxide emissions from burning fossil fuels. More than half the energy-related emissions come from large stationary sources such as power plants, while about a third comes from transportation. Industrial processes (such as the production of cement, steel, and aluminum), agriculture, forestry, other land use, and waste management are also important sources of greenhouse gas emissions in the United States.

For a better understanding of where greenhouse gas emissions come from, governments at the federal, state and local levels prepare emissions inventories, which track emissions from various parts of the economy such as transportation, electricity production, industry, agriculture, forestry, and other sectors. EPA publishes the official national inventory of US greenhouse gas emissions, and the latest greenhouse gas inventory shows that in 2005 the U.S. emitted over 7.2 billon metric tons of greenhouse gases (a million metric tons of CO2 equivalents (MMTCO2e) is roughly equal to the annual GHG emissions of an average U.S. power plant.)

Health and Environmental Effects

Climate change affects people, plants, and animals. Scientists are working to better understand future climate change and how the effects will vary by region and over time.

Scientists have observed that some changes are already occurring. Observed effects include sea level rise, shrinking glaciers, changes in the range and distribution of plants and animals, trees blooming earlier, lengthening of growing seasons, ice on rivers and lakes freezing later and breaking up earlier, and thawing of permafrost. Another key issue being studied is how societies and the Earth's environment will adapt to or cope with climate change.

In the United States, scientists believe that most areas will to continue to warm, although some will likely warm more than others. It remains very difficult to predict which parts of the country will become wetter or drier, but scientists generally expect increased precipitation and evaporation, and drier soil in the middle parts of the country. Northern regions such as Alaska are expected to experience the most warming. In fact, Alaska has been experiencing significant changes in climate in recent years that may be at least partly related to human caused global climate change.

Human health can be affected directly and indirectly by climate change in part through extreme periods of heat and cold, storms, and climate-sensitive diseases such as malaria, and smog episodes.

What You Can Do

Greenhouse gases are emitted as a result of the energy we use by driving and using electricity and through other activities that support our quality of life like growing food and raising livestock. Greenhouse gas emissions can be minimized through simple measures like changing light bulbs in your home and properly inflating your tires to improve your car's fuel economy. The What You Can Do section of the climate change site identifies over 25 action steps that individuals can take to decrease greenhouse gas emissions, increase the nation's energy independence and also save money.

State and local governments and businesses play an important role in meeting the national goal of reducing greenhouse gas intensity by 18 percent by 2012. For example, major corporations, states and local organizations are taking action through participation in a wide range of EPA and other federal voluntary programs.

You can start by assessing your own contribution to the problem, by using EPA's personal greenhouse gas emissions calculator to estimate your household's annual emissions. Once you know about how much you emit, you use the tool to see how simple steps you take at home, at the office, on the road, and at school can reduce your emissions.

Answer 8

This is just like the sixties when they were arguing whether cigarettes were good or bad.  One of the sides is getting paid to put out facts that point us in the wrong direction.  

Recycling still doesn't hurt

Answer 9

its true and we are feeling it here in the Philippines..the temperature rises to 36-38 degrees specially in Manila..it is so hot in here!!!!^^

Answer 10

Regardless of what Al tells you scientific evidence like that done by the scientists who signed the oregon petition says otherwise. The Earths climate change is a natural cycle and co2 really doesn't effect that much.

oh and by the way electric cars would be bad from the enviroment because the electricity they run on comes from burning coal. So Hybrids are bad.

Answer 11

Global warming is real enough the hoax is that some believer have the idea by raising taxes and changing our behavior that we are going to change climate.  I am all for more efficient,  and more affordable energy however this is not the way to approach it.  Raising taxes only means more money for the government to waste and less for the tax payers.

Answer 12

It is definitely a real thing but the controversy is about whether or not the cause is from mankind. There are facts to back both theories up so it's hard to decipher. One thing is for sure, man certainly sped up the process...

Answer 13

it is real, the reason is that in the yar 2000 the hottest temperature in utah was about 110 degrees F but in 2007 the hottest temperature is 130 Explan that without global warming GOOD LUCK

Answer 14

It's real

Answer 15

its real but the hoax is that its dangerous and we can do something about it.

Answer 17

If you are searching for truth you wouldn't use the term, 'hoax.' You might refer to claims as being exagerated, or built on false premises, or ?, but by using the word hoax you indicate your mind is closed unless you see the 'smoking gun.'

I'll give you some sites to spend some time with if you are indeed in search of truth.  I believe the truth is that human actions since the Industrial Revolution have impacted our world, our current and future climate, and that we are at a crossroads.  We can decide to make the kinds of changes that ensure a healthy, economically sound future for humans and the planets other occupants, or we can continue with business as usual and spend the rest of our days doing damage control.  Moving cities to high ground.  Trying to maintain fresh water supplies.  Trying to adjust our agriculture to  crops appropriate for shifting climate patterns.  Dealing with the impacts of increased vector populations, such as mosquitoes and ticks.

I don't believe everything that's said, but in stepping way back and refamiliarizing myself with the components of atmosphere and how human impacts affect our atmosphere, I was able to understand the concept of global climate change and how it is affecting my life, and how it could affect the lives of my children, their children, and generations to come.

Answer 18

More good reasons:

1. Al Gore is making money selling carbon credits

2. Global Warming is something the government can blame EVERYTHING on and people will believe them.

3. Green products are more expensive and will make more money for companies who are "going green".

If the earth is heating up, why are we having record cold winters?
