Large cold-independent "climate change"

Large cold-independent "climate change"

Although most areas affected by the large northern hemisphere cold wave of attacks, but there is as yet no evidence of it and global climate changes have a direct contact.

As if in protest of the Copenhagen Conference just ended, most recently the entire northern hemisphere into a big cold wave.

Cold wave is the winter due to high latitudes is moved to the Air Corps show dramatic cooling for a short time.

It can often be divided into a wave in a wave of weather events, and generally last for a week or so, the extent of up to several thousand kilometers, the temperature will be after the end of the year. This shows that the cold is the local short-term phenomenon of weather disasters, the most advanced in the short term weather forecast can be extremely accurate predictions. Now scientists know that cold outbreak with polar Cold air where the level of activity, as well as the characteristics of atmospheric circulation in the northern hemisphere. When the polar pile up too many cold air, or originally straight "things" to the atmospheric circulation is tortuous, the polar Cold air can easily from high latitudes "pour out", like floods across the top of the dam.

Cold outbreaks are often more region has successively "global" event.

Does this mean that cold wave is a direct result of global warming?, at least to present observations and theoretical research results it appears that there is no direct contact. Although the cold statistics can show some of the trends of climate change, can be one or two cold process does not indicate a problem.

In fact, global climate change is often through energy conservation perspective.

The Earth receives energy and release of radiation, mainly by the Sun, the Earth's surface albedo, the atmosphere of nature, and several other major factors.As a hotel, as long as you keep the gate point clearly come in out of the hotel's guests total change is clear. Intergovernmental Panel on climate change (IPCC) is currently published climate change research results the most comprehensive and most authoritative bodies. In 2007 they released fourth assessment report identified the anthropogenic emissions of greenhouse gases on the global climate warming effect. In short, they measured before the various factors mentioned, found that anthropogenic emissions of greenhouse gases prevented the Earth of the energy release. Just like a hotel much a plug in to the hotel door won't let go of the passenger to leave the billing for the security, if the number of incoming tourists not changed significantly, the entire hotel will be lived more and more visitors.

To include cold, extreme weather, such as the frequency, intensity, the report of the IPCC assessment made it clear that the current level of awareness is low.

These are followed by atmospheric circulation of the heat, power and other factors. These can be compared to know the total number of guests, the hotel and then analyze the building guests active status, you need more detailed observations and analysis. Therefore, global climate change study also needs to continue, whether it is used to make predictions of numerical model or observation techniques are also can increase the space, which is a lot of scientists are studying the frontier.

Scientists can explicitly confirm that global climate change and the cold wave, hurricanes, and other local hazardous weather direct drive mechanism, certain so-called "environmentalists" propaganda similar weather is "global warming", is speculation.

Similarly, just as cold wanted to overthrow the "global warming" is a much simpler reckless. Anthropogenic emissions of greenhouse gases on climate warming effect is already too many aspects of argumentation — — although perhaps not as some people describe as alarmist. Global climate change, there are many uncertain factors and unknown in interaction, local climate change. We can work together with the climate researchers and rational approach to this concern, after all, we really only have one Earth.
