Global Warming

The Global warming theory emphasizes that the average temperature of the Earth’s near-surface air and oceans has risen in recent decades and continues to do so.
The Earth’s climate is being directly affected by human activity, and for many people around the world, these changes are having negative effects. Records show that 11 of the last 12 years were among the 12 warmest on record worldwide. Human industrial activity is driving global temperature rises. Carbon dioxide levels today are nearly 30 percent higher than they were prior to the start of the Industrial Revolution, based on records extending back 650000 years.
An increase in global temperatures is expected to cause other changes, including sea level rise, increased intensity of extreme weather events, and changes in the amount and pattern of precipitation. Other effects include changes in agricultural yields, glacial retreat, species extinctions and increases in the ranges of disease vectors.
Remaining scientific uncertainties include the exact degree of climate change expected in the future, and how changes will vary from region to region around the globe. There is ongoing political and public debate on a world scale regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences. Most national governments have signed and ratified the Kyoto Protocol, aimed at reducing greenhouse gas emissions.
The scientists now recognize that the current growth of greenhouse gas emissions must be reversed and that emissions must be reduced substantially in order to combat the risk of climate change. Yet a dramatic increase in coal-fired power generation threatens to overwhelm all other efforts to lower emissions and virtually guarantees that these emissions will continue to climb. This would preclude any possibility of stabilizing greenhouse gas concentrations in the atmosphere at levels that would acceptably moderate the predicted rise in global temperature

Disadvantages of Global Warming

  • Ocean circulation disrupted, disrupting and having unknown effects on world climate.
  • Higher sea level leading to flooding of low-lying lands and deaths and disease from flood and evacuation.
  • Deserts get drier leaving to increased desertification.
  • Changes to agricultural production that can lead to food shortages.
  • Water shortages in already water-scarce areas.
  • Starvation, malnutrition, and increased deaths due to food and crop shortages.
  • More extreme weather and an increased frequency of severe and catastrophic storms.
  • Increased disease in humans and animals.
  • Increased deaths from heat waves.
  • Extinction of additional species of animals and plants.
  • Loss of animal and plant habitats.
  • Increased emigration of those from poorer or low-lying countries to wealthier or higher countries seeking better (or non-deadly) conditions.
  • Additional use of energy resources for cooling needs.
  • Increased air pollution.
  • Increased allergy and asthma rates due to earlier blooming of plants.
  • Melt of permafrost leads to destruction of structures, landslides, and avalanches.
  • Permanent loss of glaciers and ice sheets.
  • Cultural or heritage sites destroyed faster due to increased extremes.
  • Increased acidity of rainfall.
  • Earlier drying of forests leading to increased forest fires in size and intensity.
  • Increased cost of insurance as insurers pay out more claims resulting from increasingly large disasters.

Advantages of Global Warming

  • Arctic, Antarctic, Siberia, and other frozen regions of earth may experience more plant growth and milder climates.
  • Northwest Passage through Canada’s formerly-icy north opens up to sea transportation.
  • Less need for energy consumption to warm cold places.
  • Fewer deaths or injuries due to cold weather.
  • Longer growing seasons could mean increased agricultural production in some local areas.
  • Mountains increase in height due to melting glaciers, becoming higher as they rebound against the missing weight of the ice.

Who’s Really lying about Global Warming and Global Cooling

Now lets look at the other side of the issue. The NCPA is a not-for-profit organization that has some financial backers like say… uh …. ExxonMoblie and DaimlerChrysler Corporation Fund who might have a bit more o fan interest in showing Global Cooling than Global Warming.
The concept of global warming didn’t enter the public consciousness until the 1980s. During a sweltering summer in 1988, pioneering NASA climatologist James Hansen famously told Congress he believed with “99 percent confidence” that a long-term warming trend had begun, probably caused by the greenhouse effect. As environmentalists and some in Congress began to call for reduced emissions from the burning of fossil fuels, industry fought back.
In 1989, the petroleum and automotive industries and the National Association of Manufacturers forged the Global Climate Coalition to oppose mandatory actions to address global warming. Exxon—later ExxonMobil—was a leading member, as was the American Petroleum Institute, a trade organization for which Exxon’s CEO Lee Raymond has twice served as chairman. “They were a strong player in the Global Climate Coalition, as were many other sectors of the economy,” says former GCC spokesman Frank Maisano.
Drawing upon a cadre of skeptic scientists, during the early and mid-1990s the GCC sought to emphasize the uncertainties of climate science and attack the mathematical models used to project future climate changes. The group and its proxies challenged the need for action on global warming, called the phenomenon natural rather than man-made, and even flatly denied it was happening. Maisano insists, however, that after the Kyoto Protocol emerged in 1997, the group focused its energies on making economic arguments rather than challenging science.
Now it is now wonder they want to make people believe that those are myths. So, are they myths or not? You’ll have to decide.

“Most geologists think the world is growing warmer, and that it will continue to get warmer.” L.A. Times 1929

MELTDOWN: According to scientists, global warming has caused the Columbia Glacier to retreat seven miles in the last 20 years, leaving calves of ice in Prince William Sound.
AT RISK: On the frozen Beaufort Sea outside the Inupiat village of Kaktovik, Alaska, a polar bear pauses from a meal of whale meat. The 3,800 polar bears along the Alaskan coast face an uncertain future as global warming melts more summer sea ice each year.

WHAT WE CAN DO TO HELP?

Choosing modern technology can reduce our use of fossil fuels and help protect the planet. The choices we make and the products we buy test our commitment to maintain a healthy planet. When we burn fossil fuels—such as oil, coal, and natural gas—to run our cars and light our homes, we pump carbon dioxide (CO2) into the air. Here are some examples:

  • Drive Smart: A well-tuned car with properly inflated tires burns less gasoline—cutting pollution and saving you money at the pump. If you have two cars, drive the one with better gas mileage whenever possible. Better yet, skip the drive and take public transit, walk, or bicycle when you can.
  • Replace incandescent light bulbs with compact fluorescent bulbs: Especially those that burn the longest each day. Compact fluorescents produce the same amount of light as normal bulbs, but use about a quarter of the electricity and last ten times as long. Each switch you make helps clean the air today, curb global warming, and save you money on your electricity Hill
  • Become a smart water consumer: Install low-flow showerheads and faucets and you’ll use half the water without decreasing performance. Then turn your hot water heater down to 120°F and see hot-water costs go down by as much as 50 percent
  • Plant a Tree, protect a forest: Protecting forests is a big step on the road to curbing global warming. Trees “breathe in” carbon dioxide, but slash-and-burn farming practices, intensive livestock production, and logging have destroyed 90 percent of the native forests in the United States. And you can take action in your own backyard — planting shade trees around your house will absorb CO2, and slash your summer air-conditioning bills.
  • Reduce! Reuse! Recycle!: Producing new paper, glass, and metal products from recycled materials saves 70 to 90 percent of the energy and pollution, including CO2, that would result if the product came from virgin materials. Recycling a stack of newspapers only 4 feet high will save a good-sized tree. Please…buy recycled products.
