What is climate change?

Hello Susmita,

Climate Change – Definition

ˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉˉ

Climate Change is a term that is usually used to describe the inadvertent changes that are occurring to worldwide climates as a consequence of global warming. Global warming, in this context, is the warming of the Earth as a result of increased human emissions of greenhouse gases – the types of gas that retain heat in the atmosphere.

Climates can also change naturally although this is a very slow process occurring over thousands and millions of years.

Climate Change – Causes

Within the atmosphere are numerous gases we call the greenhouse gases, so called because they have the ability to retain heat energy. This process keeps our planet at a habitable temperature and allows life to exist, it’s what we refer to as the greenhouse effect.

Natural processes both release and absorb greenhouse gases, most notably carbon dioxide, and this system is balanced.

Humans on the other hand only ever release greenhouse gases, billions of tonnes of them every year. Our emissions far exceed anything that nature can handle and the excess gases are accumulating in the atmosphere, this causes the greenhouse effect to intensify leading to more heat being retained and the world warming up.

Climate Change – Effects

The world has warmed by a little under 1°C in the last 100 years or so, it’s predicted to rise by a further 2°C to 3°C in the next 100 years. Along the way there are short periods of cooling or static temperatures caused by short-term natural influences, the overall trend is of increasing temperatures.

Warmer conditions bring about many changes, some are positive others are negative; often it depends where in the world you are. For example, in cooler parts of the world there will be an increase in agricultural yields as the temperatures rise; but in the places that are already hot, it becomes even harder to grow crops and yields are falling.

Perhaps the most obvious effect is on the weather. Globally the weather is becoming increasingly disrupted. Droughts, floods and heatwaves are now much more common than they used to be and again, this can be both a good or bad thing – depending very much on what the existing weather conditions are like; more rain in an arid region is a benefit but more rain in a place that’s already wet can lead to flooding.

There’s a huge number of effects, I won’t go into detail but they include: effects on ecosystems, changes to hibernation and migration patterns, spread of diseases and disease vectors, contamination of water sources, rising sea-levels, longer growing seasons, decreased snowfall, melting of permafrost, expansion of deserts, melting of polar ice, changes (good and bad) to water supplies and distribution, physiological effects, both the loss and gain of habitat zones, formation of new lakes and rivers, the opening of sea-routes around the north of Canada and Russia etc etc.

A change in the climate according to the UN-IPCC. And that is the only definition they give.

In reality, the catastrophic part of it has never been defined so that a scientist, for example, say X, Y and Z happened so that equals Climate Change as defined by the IPCC.

This ambiguity is not accidental. It only implies a danger, it never defines it. That way you can scare a lot of the uninformed and raise taxes and enact tyrannical legislation.

Quotes by H.L. Mencken, famous columnist: "The whole aim of practical politics is to keep the populace alarmed — and hence clamorous to be led to safety — by menacing it with an endless series of hobgoblins, all of them imaginary." And, "The urge to save humanity is almost always only a false face for the urge to rule it."

Climate Change is an enormous global SCAM to rob us blind and destroy our freedoms.

What global warming/climate change? It's been cooling for at least 12 years according to HadCrut3 & 4.

According to RSS Satellite data there has been no warming for almost 18 year.



Just what it implies. Today, the argument is over global warming.

You will see people post that warming has stopped. Or it's cooling. Or it's been warming since the end of the ice age. Or this or that scientist or professor emeritus says it's not warming. Hogwash. It is warming.

http://en.wikipedia.org/wiki/Global_warm...

"The finding that the climate has warmed in recent decades and that human activities are already contributing adversely to global climate change has been endorsed by every national science academy that has issued a statement on climate change, including the science academies of all of the major industrialized countries."

climate change is a process where global warming occurs for 10,000yrs and global cooling 100,000. During this cycle there are minor variables/trends.

a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.

Something that has happened ever since the big bang. Silly buggers today think we can control it if only we stop driving to work.

Process of changing weather in the environment that is not happen in a day.
