Hello everyone. we are back again in our segment “talk back Thursday” where we open up debatable topics and hope to get a positive feedback from you all. Till date we have been worrying about global warming to be an alarming issue right? Have you thought about ice age being such a disturbing effect on our environment?While a significant number of people and world leaders are concerned about global warming,a renowned solar physicist has come up with a theory that is entirely contradictory.
Research: Professor Valentina Zharkova, a solar physicist at the UK’s Northumbria University, claims that the earth is in fact not warming up, but cooling down. She has been conducting extensive research on sunspots – ominously cooler regions of the sun’s surface characterized by intense magnetic activity – pivotal in influencing climate patterns. According to some researchers, the current increase in global temperatures is a result of increased sunspot activity rather than the emission of greenhouse gasses.Sunspot activity is likely to fall – similarly to what took place during the Maunder Minimum or “The Little Ice Age.” This will culminate in drastic drops in temperature and more winter-like conditions. Zharkova observed that solar activity had a significant influence on past climate trends.News has emerged following some research aided by NASA and confirmed by USGS satellite imagery, that Antarctica may be growing in size and mass, which has been supported by cooling patterns over the past two decades. This may indicate that the earth is cooling, and further supports the findings of Zharkova.
Global warming is an inescapable issue for our age. But 180 years ago, most scientists believed that Earth had been steadily cooling since it was formed. When Louis Agassiz presented the concept of a Great Ice Age to the Swiss Society of Natural Sciences in 1837, his suggestion that the planet had turned colder and then warmed up again was met with skepticism and even hostility, triggering years of fierce scientific debate before the idea was accepted.
There’s little question that global warming is happening. Climate data show that Earth’s average temperature has risen at least 0.7 oC (1.3 oF) over the 20th century. Temperature increases over the 21st century will probably be two and a half to five times as large,because greenhouse gases like carbon dioxide allow sunlight to penetrate the atmosphere but make it harder for outgoing infrared radiation to escape. What’s more, just as carbonated soda fizzes when it warms up, warmer temperatures cause the ocean to release carbon dioxide taken up during colder periods.
Over the past couple of decades such warnings have been drowned out by the great global warming debate and by consideration of how society might cope in future with a sweltering planet rather than an icebound one.
Once considered incredible, the notion that climate can change rapidly is becoming respectable. In a report, Robert Gagosian cites “rapidly advancing evidence [from, e.g., tree rings and ice cores] that Earth’s climate has shifted abruptly and dramatically in the past.” For example, as the world warmed at the end of the last ice age about 13,000 years ago, melting ice sheets appear to have triggered a sudden halt in the Conveyor, throwing the world back into a 1,300 year period of ice-age.
Will it happen again? Researchers are scrambling to find out.
And, inevitably, the discussion turns to people. Does human industry play a major role in warming the Arctic? Could we reverse the trend, if we wanted to? Not all scientists agree. Some argue that the changes occurring in the Arctic are consistent with large, slow natural cycles in ocean behavior that are known to science. Others see a greater human component.According to some researchers, the heat trapped in the Earth’s atmosphere from the greenhouse effect will offset this cooling — essentially preventing the Earth from entering another ice age
This means that humanity will be hit by a one-two punch the likes of which we have never seen. Nature is as unforgiving to men as it was to dinosaurs; advanced civilization will not survive unless we develop energy sources that curb the carbon emissions heating the planet today and help us fend off the cold when the ice age comes. Solar, nuclear, and other non-fossil-fuel energy sources need to be developed now, before carbon emissions get out of hand. And there are fortunes to be made from the effort. It’s worth thinking about.
The question of whether reversing global warming might lead to an ice age could be irrelevant if it never happens. According to a study by the National Oceanic and Atmospheric Administration (NOAA), the changes in ocean surface temperature, rainfall, and sea level that have already occurred are irreversible for a thousand years after carbon dioxide emissions are completely stopped.That means no matter how much we curb our emissions today, we may not be able to undo the damage that has already been done anytime soon.
Perhaps the world should come around to the idea that we had better all start perparing ourselves for a very long winter. The one thing scientists do seem to agree on is that another ice age is not likely to occur for thousands of years — not even remotely close to any of our lifetimes. What do you feel about this?Which of these two do you support and feel poses a more severe threat? What do you think can be a measure to protect our environment?
