Darkening Arctic making Earth warmer

WASHINGTON — The Arctic isn't nearly as bright and white as it used to be because of more ice melting in the ocean, and that's turning out to be a global problem, a new study says.

And left out of this report is the fact the SUN is right now throwing more energy at our planet than it has for a few hundred years now. Waiting for liberals to tell us why this is man's fault and how much we have to spend to fix the sun's problem...

"Historical records of solar activity indicate that solar radiation has been increasing since the late 19th century. If a trend, comparable to the one found in this study, persisted throughout the 20th century, it would have provided a significant component of the global warming the Intergovernmental Panel on Climate Change reports to have occurred over the past 100 years," he said. NASA's Earth Science Enterprise funded this research as part of its mission to understand and protect our home planet by studying the primary causes of climate variability, including trends in solar radiation that may be a factor in global climate change.

Once again the sky is falling All because of evil man and his activities Nothing about the sun or other causes When will we get a honest report I for one am getting sick and tired of these bias reports

There has been a 60 per cent increase in the amount of ocean covered with ice compared to this time last year, they equivalent of almost a million square miles. In a rebound from 2012's record low an unbroken ice sheet more than half the size of Europe already stretches from the Canadian islands to Russia's northern shores, days before the annual re-freeze is even set to begin. The Northwest Passage from the Atlantic to the Pacific has remained blocked by pack-ice all year, forcing some ships to change their routes. A leaked report to the UN Intergovernmental Panel on Climate Change (IPCC) seen by the Mail on Sunday, has led some scientists to claim that the world is heading for a period of cooling that will not end until the middle of this century. If correct, it would contradict computer forecasts of imminent catastrophic warming. The news comes several years after the BBC predicted that the arctic would be ice-free by 2013. Despite the original forecasts, major climate research centres now accept that there has been a “pause” in global warming since 1997. – Hayley Dixson Sept 2013

Did the study consider the additional sea ice that formed around Antarctica during the same period? Do the record sea-ice levels in the south polar region these days occur only in their winter or does the ice persist into their summer and reflect additional sunlight? These seem like fairly obvious points to consider in such a study.

Annnnnnnd queue the climate denying ignoramuses with their mythical excuses about how this is 100 percent to blame on warmer sun energy, cyclical climate, unicorns, or whatever else Exxon has paid enough to sucker them into believing...

People assume understanding the climate is as simple as looking at weather records and making models from that. When in reality the amount of variables that influence our current climate are almost inconceivable. Pretty much all climatologists have moved away from the word "Global warming" because models have shown that not all places in the world will heat up, some places actually will cool down. Why? Because variables can change in weird and unexpected ways. For example, warming oceans may have an impact on ocean currents which usually heavily determines the climate of an area. Say a warm ocean current changes direction due to a shift in overall ocean temperature and stops pumping warmer water into a certain area. That place will actually cool off. It is believed that the last ice age actually was caused because an ocean current bringing warm water from the caribbean to the northern latitudes basically shut off, thus more ice was able to form and because of the increasing ice and its albedo, (The ability for ice to reflect solar radiation back into the atmosphere) a runaway cooling effect occurred. Please just google search overall average temperature change over last 2000 years, it is increasing at an very alarming rate. A rate at which many species in the world will not be able to adapt to. These species will likely go extinct, including many vital for our ecosystems and for food. Also be thankful that it is not believed that this increase in temperature will cause a runaway warming effect, at least as of yet. As for the recent cold snap, that is because the jet stream has been stuck in place due to high pressure systems stalled over warm ocean waters. And besides, I do not understand why people continue to believe that making our world more environmentally friendly is bad in the first place. A good amount of the people against it are people who make money off of businesses that tend to damage our environment such as oil companies. It is very sad to say that some people simply do not care about what happens to the people a couple generations down the road.

The Earth goes through warming periods and cooling periods, if we happen to be during a warming period at the same time we have put unprecedented amounts of crud into the atmosphere it sure exacerbated the problem. However the Earth will provide a correction at some point, as per the historical climate records.

tkr380 - A change in the amount of energy the sun outputs has almost no effect on the earth's temperature. The amount of radiation decreases at an exponential rate as it travels through space. So a large change in the sun's energy output becomes a microscopic difference here on Earth. For it to be noticeable, the sun's radiation output would have to increase a very drastic amount. Orientation of the Earth and the proximity of the Earth to the sun are really the biggest factors in determining how much the Earth is heated by the sun. Orientation changes to me and you are known as seasons. And changes in the distance from the Sun and Earth generally are only noticable if you look at a time scale of a hundred thousand years.

I might give credit to the 'theories' of those who deny greenhouse gas emissions contribute to climate change...I might, if they tended to be the same people who believed in the overwhelming scientific evidence showing that evolution takes place, or that earth is more than 6000 years old...I might, but of course, I don't.
