Global Warming 101 (4 of 5) - Current Conditions

Over the last 30 years, how has human forcing on the climate compared to natural forcings, and what has been the Earth's climatic reaction to this combination of forcings?

Obviously you've forgotten about the undeniable correlation between the Maunder Minimum and the Little Ice Age.

The only thing you can do to refute them is deny their existence. Who's the "denier" now, considering the history books can't be changed to suit your ideology.

@MrOllyK

The reduced solar activity associated with the LIA is specifically mentioned in the video. That such a correlation exists between increased solar activity and the MWP and decreased solar activity and the LIA reinforces the attribution of current warming to human activities during the current solar minimum and decline of activity over the last 30 years.

Greed and jelousy are the worlds problems if we can get past them well never solve shit, bout time some people picked up a pencil and some paper and did some real research like Michael searcy and helped to educate this planet instead of destroy it like u richard482, people like u make me sick, its unfortunate that theres people like you on earth and its about time that changed, its about time the world changed and starting working for the positive not the negative

[ufoastrology]

negligence and not believing its happening is the problem people like you are our problem and have been holding back the positive thinkers for years, its people like you who are destroying our ecosystems and our planets species, people like you are the reason global warming exists today , its about time negative thinkers like you woke up, do us all a favour and do some damn research before you post your negative propaganda to the world.

[ufoastrology]

Richard 482 are you blind do more research look at our ozone and tell me what happens when its depleted and nothing is holding oxygen on our planet does life exist then and why are scientists research showing that its depleting open your eyes you can see global warming all around you, education is they key to finding an answer to global warming, research of our atmosphere and ozone could lead to the discovery of how to add to the ozone layer and stop global warming that way.

really informative and interesting

@Richard482 I have seen all the recommended propaganda you quote religiously. The fact remains that man made global warming is a nonsense. The climate will continue to go through cycles of warming and cooling. Continuous warming is a myth generated in computer models , welcome to the real world. Google daily arctic sea ice maps, lets watch what the north pole does.

[Richard482]

@david222444 I've looked at your favourited video's including the scientists predicting an ice age in the 70's one. Try watching the following series' of video's. I know it is alot to watch but they are very informative on the subject of climate change

Thank you in advance. Richard

@david222444 "clouds formed from water vapour are a negative feedback." If you mean that clouds act as a negative feedback because clouds reflect sunlight and cool the earth down, that area is a bit tricky because clouds do both. I've messaged you a couple of links.

[Richard482]

@david222444 "The Planet at present is cooling abruptly." Got any links to any graphs or data sets to support this?

[david222444]

@Richard482 Clouds are formed from the condensation of this water vapour when it is cooled . The conclusion must be that clouds formed from water vapour are a negative feedback.
