What is the diference between climate change & global warming?

Global Warming [GW] refers to the current trend of increasing global average temperature as recorded by various independent means. There is no real argument on this. the measurements exist the atmosphere is warming not by much but by measurable amounts. GW does not mention the reason for this warming

Anthropogenic Global Warming [AGW] refers to the current warming trend and says this is caused in whole or mostly by human activity. [burning of fossil fuels, adding other green house gases to atmosphere, destruction of forests, massive cattle numbers etc]

Climate Change refers to the changes in climate that are resulting from GW [without saying if its natural warming or AGW because any warming will cause climate change]

The warming is minor in terms of temperature difference. Less than 1 degree in the last century. But it is massive in the amount of energy that represents. We would be hard pressed to feel the temperature difference, but the increased energy has already affected climates around the world and that we can notice.

Climate is very sensitive to even small average temperature changes. The consensus amongst those who study climate is that just 2 or 3 degrees total warming is enough to tip the scales very badly against humans. We are currently just 6 degrees warmer on average than the last ice age. All the evidence suggests that if we increase the global average by 3 or more degrees we set off a number of natural feedback loops that will send the temperature even higher all by itself.

Climate Change has not replaced GW or AGW, they have different meaning.

Climate Change is used when discussing the effects of GW. This is because GW is based on average long term temperatures over the whole planet. But because of the complex climate system on the plant some areas may actually get colder even while the planet as a whole is getting warmer.

Also climate change better expresses the concerns because its not just a problem of temperature, but of changing rainfall and wind patterns.

Think of the poor investor who builds a major wind farm only to find in a decade that the wind pattern has changed and his multi million investment is sitting idle. Or worse the wheat farmer who finds that the rainfall is now mostly in the harvest season so his crop does not grow well and he can't harvest damp wheat. Or the banana farmer who finds that he cannot get enough water to his crops because the rains have virtually stopped in his part of the world. All these ans much more are the effects of climate change. Climate change is driven by the increased and changing energy caused by GW and GW is AGW because we have dramatically altered the amount of green house gasses on the planet and removed much of its forest cover. 7 billion humans do have an impact on this planet.

Changing climates would affect large numbers of people across great areas of the world. But the climate would end up being completely different from what previously existed. Temperate climates would become sub tropical with some areas becoming desert rather than plains. Tundra would disappear and temperate climate would replace it. Of course, this assumes that there are no self-correcting mechanisms within earth's weather systems. If our weather is the primary force in distributing heat gain evenly over the entire world then it must also be the primary force in cooling the planet, no?

Global warming is simply acknowledging increases in world temperature. Climate change encompasses much greater things and is much less evident at this time. Of supreme concern today ought to be the drastic reduction of tropical rainforest along the equator in order to achieve more farming land. A very poor choice indeed.

1. I think, Climate Change is the ''DEVIATION from the Natural Environmental Phenomena'' All Over the WORLD. Global Warming is Occur Due to the High Pollution of CARBON GASES , Which Increase the TEMPERATURE of The WORLD and GLOBAL ATMOSPHERE. Global Warming Lead to the Climate Change. 2. I Don't Know, Details of Greenhouse effect, For My Understanding, I think, Both Global Warming and Climate Change are ,Both Affect the WORLD Natural Behaviour, Which is the the Green house Effect. 3. AGRICULTURE, Due to Climate Change, All Over the WORLD the BASIC need of the Human Food, AGRICULTURE is Affected by this. AFRICA is One of the Poorest Continent is the AFFECTED MOST. SOMALIA , ETHIOPIA are the Most affected Countries With HIGH DROUGHT with out FOOD, and CHILDREN are Dying with Malnutrition without FOOD for 2 Decade. Now International WWF and UN all are trying to Save the DISPLACED Families and CHILDREN, I think, It will continue Through out the WORLD.

What Climate Change Means In short

Climate is the description of the long-term pattern of weather in a particular area.

Some scientists define climate as the average weather for a particular region and time period, usually taken over 30-years or more . It's really an average pattern of weather for a particular region like Australia at the moment.

GLOBAL WARMING MEANS --.

NASA has been using satellites to study Earth's changing climate. Thanks to satellite and computer model technology, NASA has been able to calculate actual surface temperatures around the world and measure how they've been warming. To accomplish the calculations, the satellites actually measure the Sun's radiation reflected and absorbed by the land and oceans. NASA satellites keep eyes on the ozone hole, El Nino's warm waters in the eastern Pacific, volcanoes, melting ice sheets and glaciers, changes in global wind and pressure systems and much more. .

The meaning of 'climate change' is fairly straightforward—a clear, sustained change (over several decades or longer) in the components of climate, such as temperature, precipitation, atmospheric pressure, or winds. Such changes must constitute a clear trend, and be clearly distinguished from the small random variation in these parameters that takes place all the time. That is why climate change can only be determined after careful analysis of several decades of observations. In this context, it is important to understand clearly the difference between climate and weather.

The refer to the same thing. Climate change is more used in the scientific community. Global Warming is more slang.

Global warming is the cause whereas Climate Changes are the result. and as a result the weather has changed all around the world -20 degrees in africa

The term "climate change" was coined, when global warming became too hard to sell. In the US, climate change is being phased out now in favor of "global climate disruption."

Global warming is the cause whereas Climate Changes are the result

Global warming is a scam.

I think the best way to understand this scam is to read Harold Lewis' letter of resignation from the American Physical Society (APS). I quote from that letter here.

"It is of course, the global warming scam, with the (literally) trillions of dollars driving it, that has corrupted so many scientists, and has carried APS before it like a rogue wave. It is the greatest and most successful pseudoscientific fraud I have seen in my long life as a physicist"

Harold Lewis is Emeritus Professor of Physics, University of California, Santa Barbara, former Chairman; Former member Defense Science Board, chairman of Technology panel; Chairman DSB study on Nuclear Winter; Former member Advisory Committee on Reactor Safeguards; Former member, President's Nuclear Safety Oversight Committee; Chairman APS study on Nuclear Reactor Safety Chairman Risk Assessment Review Group; Co-founder and former Chairman of JASON; Former member USAF Scientific Advisory Board; Served in US Navy in WW II; books: Technological Risk (about, surprise, technological risk) and Why Flip a Coin (about decision making)
