Climate Change: Global Warming or Global Cooling?

| This diagram shows how the greenhouse effect works. Incoming solar radiation to the Earth equals 341 watts per square meter (Trenberth et al., 2009). Some of the solar radiation is reflected back from the Earth by clouds, the atmosphere, and the Earth's surface (102 watts per square meter). Some of the solar radiation passes through the atmosphere. About half of the solar radiation is absorbed by the Earth's surface (161 watts per square meter). Solar radiation is converted to heat energy, causing the emission of longwave (infrared) radiation back to the atmosphere (396 watts per square meter). Some of the infrared radiation is absorbed an re-emitted by heat-trapping "greenhouse" gases in the atmosphere. Outgoing infrared radiation from the Earth equals 239 watts per square meter. |
Global warming. It is a phrase that mostly makes sense to those who are alert on matters related to climate change. Or is it?
According to the Oxford Dictionary; "Global Warming is a gradual increase of the earth’s temperature due to greenhouse effect caused by the increase in carbon dioxide, chlorofluorocarbons and other pollutants."
Just six years ago, the BBC predicted that more than a million arctic seas filled with ice will have melted away by the summer of 2013. And now? There is an extraordinary “reverse” of global warming that has led to a 60% rise in ice covered ocean. Global warming has “paused”.
Leaked documents show that governments which support and finance IPCC are demanding more than 1500 changes to the reports by scientists. They say its current draft does not properly explain the “pause”. Recent reports show that there is a 60% increase in the amount of ocean covered with ice compared to September last year, the equivalent of almost a million square miles. A leaked report to the UN intergovernmental panel on climate change 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 that is for at least 15 years, Professor Anastasios Tsonis, of the University of Wisconsin said. The changing predictions led to the Intergovernmental Panel on Climate Change holding a crisis meeting, and released a report on the situation in October 2013.
On the back of these dire warnings, billions of pounds were invested in green measures to combat agents of climate change such as greenhouse gas emissions. But the secret UN memo reveals that the ice has spread quickly following the smallest ever frozen surface area, this time last year.

| On a speculative note do you wonder about why August 2013 was cold and September 2013 was not as hot. Well, this explains it all. *raised eyebrows and side eye* |
The severe drought, combined with massive crop failures and poor agricultural policy on the part of the Assad regime, forced mass migrations from the countryside to cities that were already hard-pressed by refugees from Iraq, Femia argues. Military analysts overlooked these factors and argued that Syria would be immune to the civil unrest that had previously swept through authoritarian Middle Eastern regimes. …
“Climate change primarily manifests itself through water,” Femia added. “But it varies; different kinds of water, different ways. It can lead to more extreme weather events: either a drought or a major storm or an amount of rainfall that’s unusual and leads to flooding. It’s not just scarcity, it’s too much, too little and unpredictably.”
“Climate change is going to have security implications across the globe and conflict is just one area of concern,” Femia said.
