Fresh Research by 'Danish Space Research Centre' can possibly give a new twist to the controversy whether Green House Gas emissions is the major contributor for global warming. The Center's research based on climate date of 150 years.
The green house emissions is just one of the many factors for global warming, the space centre said. The research shows that solar activity has been has been exceptionally high in the 20th century compared to the last 400 years and possibly compared to the past 8,000 years.
- When solar activity is high, the flux of galactic cosmic rays is reduced due to increased magnetic shielding by the Sun. The cosmic rays may influence Earths climate through formation of low-lying clouds causing more warmth on the surface of the earth.
- The space centre had found that cosmic rays ionize the atmosphere. Production of aerosols in a sample atmosphere with condensable gases (such as sulphuric acid and water vapour) depends on the amount of ionization. Since aerosols works as precursors for formation of cloud droplets. Thereby, lower ionization leads to lesser cloud formation and more global warming, the research said

10 Surprising results of Global Warming
1. Aggravated Allergies: Have those sneeze attacks and itchy eyes that plague you every spring been worsening in recent years? If so, global warming may be partly to blame. Over the past few decades, more and more Americans have started suffering from seasonal allergies and asthma. Though lifestyle changes and pollution ultimately leave people more vulnerable to the airborne allergens they breathe in, research has shown that the higher carbon dioxide levels and warmer temperatures associated with global warming are also playing a role by prodding plants to bloom earlier and produce more pollen. With more allergens produced earlier, allergy season can last longer. Get those tissues ready.
2. Heading for the Hills: Starting in the early 1900s, we've all had to look to 
slightly higher ground to spot our favorite chipmunks, mice and squirrels. Researchers found that many of these animals have moved to greater elevations, possibly due to changes in their habitat caused by global warming. Similar changes to habitats are also threatening Arctic species like polar bears, as the sea ice they dwell on gradually melts away.

Arctic in Bloom: While melting in the Arctic might cause problems for plants 
and animals at lower latitudes, it's creating a downright sunny situation for Arctic biota. Arctic plants usually remain trapped in ice for most of the year. Nowadays, when the ice melts earlier in the spring, the plants seem to be eager to start growing. Research has found higher levels of the form of the photosynthesis product chlorophyll in modern soils than in ancient soils, showing a biological boom in the Arctic in recent decades.

Pulling the Plug: A whopping 125 lakes in the Arctic have disappe
ared in the past few decades, backing up the idea that global warming is working fiendishly fast nearest Earth's poles. Research into the whereabouts of the missing water points to the probability that permafrost underneath the lakes thawed out. When this normally permanently frozen ground thaws, the water in the lakes can seep through the soil, draining the lake, one researcher likened it to pulling the plug out of the bathtub. When the lakes disappear, the ecosystems they support also lose their home.

This thawing causes the ground to shrink and o
ccurs unevenly, so it could lead to sink holes and damage to structures such as railroad tracks, highways and houses. The destabilizing effects of melting permafrost at high altitudes, for example on mountains, could even cause rockslides and mudslides. Recent discoveries reveal the possibility of long-dormant diseases like smallpox could re-emerge as the ancient dead, their corpses thawing along with the tundra, get discovered by modern man..

Survival of the Fittest: As global warming brings an earlier start to spring, the early bird might not just get the worm. It might also get its g
enes passed on to the next generation. Because plants bloom earlier in the year, animals that wait until their usual time to migrate might miss out on all the food. Those who can reset their internal clocks and set out earlier stand a better chance at having offspring that survive and thus pass on their genetic information, thereby ultimately changing the genetic profile of their entire population.7. Satellites: A primary cause of a warmer planet'scarbon dioxide emissions is having effects that reach into space with a bizarre twist. Air in the atmosphere's outermost layer is very thin, but air molecules still create drag that slows down satellites, requiring engineers to periodically b
oost them back into their proper orbits. But the amount of carbon dioxide up there is increasing. And while carbon dioxide molecules in the lower atmosphere release energy as heat when they collide, thereby warming the air, the sparser molecules in the upper atmosphere collide less frequently and tend to radiate their energy away, cooling the air around them. With more carbon dioxide up there, more cooling occurs, causing the air to settle. So the atmosphere is less dense and creates less drag.8. Mountains: Though the average hiker wouldn't notice, the Alps
and other mountain ranges have experienced a gradual growth spurt over the past century or so thanks to the melting of the glaciers atop them. For thousands of years, the weight of these glaciers has pushed against the Earth's surface, causing it to depress. As the glaciers melt, this weight is lifting, and the surface slowly is springing back. Because global warming speeds up the melting of these glaciers, the mountains are rebounding faster.9. Ruined Ruins: All over the globe, temples, ancient settlement
s and other artifacts stand as monuments to civilizations past that until now have withstood the tests of time. But the immediate effects of global warming may finally do them in. Rising seas and more extreme weather have the potential to damage irreplaceable sites. Floods attributed to global warming have already damaged a 600-year-old site, Sukhothai, which was once the capital of a Thai kingdom.10. Fire Frenzy: While it's melting glaciers and creating more intense hurricanes, glo
bal warming also seems to be heating up forest fires in the United States. In western states over the past few decades, more wildfires have blazed across the countryside, burning more area for longer periods of time. Scientists have correlated the rampant blazes with warmer temperatures and earlier snowmelt. When spring arrives early and triggers an earlier snow-melt, forest areas become drier and stay so for longer, increasing the chance that they might ignite.source:http://www.livescience.com
