Just getting your opinions, please, no heated arguments.

Do you think recent global warming was/is mostly man-made or mostly natural?

Recent warming? There was some warming from the 70s-90s but I believe it has leveled off in the past 15 years. Honestly, the climate naturally cycles between cold periods (mini ice age in 17th century) and warm periods (medieval warm period in 13th century). Some summers are cold because of natural things, such as volcanoes, (1816) and some winters are warm, because of completely natural weather patterns (2011-2012). In my opinion, it's pretty much all beyond our control, influenced by nature.

It's mostly manmade... Never has our climate changed so rapidly - You've only got to look at the fact that 10 of the hottest years globally has all happened in my lifetime so far (I was born in 1995), 8 out of 10 were recorded in the 00s, and 1 was recorded back in 2013: 10 Warmest Years on Record Globally | Climate Central
To top that, this year is very likely to be the hottest year on record. Also, though the UK hasn't had any particular heatwaves this year (other than a warm Halloween) and August was the coldest month in my lifetime (average max temp of just 21C in London!), the UK is also likely to have it's warmest year on record:

This is the UK weather this year, and no snow!
Winter - Record Rainfall, the Highlands sore lots of Snow!

Spring - Finally some mild weather and the Saharan Dust and unusual Smog

Summer - Lightening every mini-second during a Spanish Plume in July, and one of the coldest August's on record - Summer was all in all Average (despite what your average Jo says)

September - Driest since records began

October - Storms and record breaking warm Halloween

November and December - Uneventful, but perhaps milder than usual in November, and December seems to have had quite a bit of sunshine

I would say the reason why Britain might have the hottest year on record, is due to a milder than usual winter through the consistent Atlantic depressions hitting the country, this by warmer ocean temps that humans have coursed. The UK has also had some pretty warm weather year round. However, I think that if we didn't have a milder than usual January and February, the UK would be far away from having it's warmest year on record, as I would say much of the year hasn't been extreme in terms of minimums and maximums. Also officially we didn't have a heatwave this year and the highest temp of 2014 was just around 32.4C - and London only had 1 day above 30C (Compared to it's usual 4 to 5 days per year). But most of June, July and early August had temps in excess of 25C making those months warmer than av.

Overall, is Climate change real - yes! You've only got to look at the events of this year in the UK, and the fact that other places in the world are experiencing the same fate. Not in that, I think it is very worrying that all the top 10 of the warmest years on record are within the last 20 years - there is something going on, and that is as a result of human behaviour! In my opinion of course...

It hasn't warmed for 18 years. Scientists generally agree that the earth warmed about 0.6 degrees over the last century.

Astronomers believe that Mars, Jupiter, Saturn, Neptune and Pluto have warmed. Due to Solar radiation?

Antarctic sea ice has been GROWING for the last 30 years.

Average ice sheet thickness in Greenland has grew by about 2 inches per year from 1993 - 2003.

I have a question for anyone who can answer it. How recent do Vostok Station ice core samples go up to? 1951? 2013? I know they go back about 420,000 years.

If the globe hasn't warmed - then why are the worlds warmest years on record recorded within the last 16 years? Hmmm? Some guys just don't see the facts and just give opinions and non-facts

I believe it is a natural cycle that the earth goes through BUT it is warming faster because of man...

Because of the order of those years. That's how. Here is what the actual RSS satellite data says. This is not an opinion, this is a fact that no scientist argues with. (Yes, there is a +/- margin of error not shown on the graph.) Notice that this flat line was achieved with almost every single month in the past 16 years being above average.

The RSS dataset is the only one that shows no warming (maybe the other satellite one is close). It also does not conflict with continued warming, continuing to warm at the same rate since 1980 is within the ± margin of error.



Every one of the 95% confidence intervals, for every choice of start year, includes the first trend estimate. None of them provides statistically valid evidence that the warming rate since any of the start years is any different than it has been all along. Bottom line: from this analysis, there’s no valid evidence that the warming rate (the trend, not the fluctuations) has changed at all.

A pause or not a pause, that is the question. | Open Mind

Not only is there no valid evidence that the “pause” has lasted 25 years or longer, there’s not even any valid evidence that a “pause” happened at all.

So if there's no climate change, then why is the Ice Caps melting at a ridiculous rate?
New satellite maps show polar ice caps melting at 'unprecedented rate' | Environment | The Guardian
Whether climate change is manmade or not is irrelevant to what I have to say here, and although I believe it is manmade, Climate Change is a real thing - this is shown by the ice-caps melting, more wildfires in places like Southern Europe, California, Australia, and other places, more rainfall and active weather right across the globe. Climate Change is happening and the world is getting warmer, hence why this year is either the hottest or second hottest year since records began. Anyone who says climate change isn't real then they are wrong, and any evidence that shows me so are most likely biased!

As for us, Fossil Fuels and producing more CO2 cannot be good for the Earth, and as a result we must advance our technology into the future and use renewable energy (except wind-farms - can't stand them!), and investment in producing Nuclear Fusion Power Plants, whereby, like the sun, we can produce our own energy without relying on oil, or the sun! The Human Race is still in the stone-age and we have to say F-off to the oil companies in favour of improved technologies! This, in my opinion, would ensure that we will be cleaner to the earth - God I do sound like a greeny, but I know that we are being unkind to the earth and we have to recognise this fact and make it right!

Not sure why some are slow to get it or ignoring it. (1 or the other).

recent eruptions could be responsible for decreasing global temperatures by 0.05 to 0.12 degrees Celsius (0.09 to 0.22 degrees Fahrenheit) since 2000.

Oceans had a big role in the warming we did have is the other thing many don't know.
