G.S. Callendar was also an important person in the debate.
In 1938, G. S. Callendar, a British amateur meteorologist, made a bold claim that may sound familiar. He argued that man was responsible for heating up the planet with CO2 emissions. Despite the previous work of Arrhenius, it still wasn’t a common notion at the time.
After watching the video I felt the main points were
Logic,
The arguments presented for global warming.
It is faulty logic to assume CO2 causes global warming or a “causal relationship”. It is like saying people with umbrellas cause it to rain.
Science. It all based on one scientific theory.
The amount of CO2 in the atmosphere is tiny and 90% comes from natural sources. Humans only contribute 7% of the CO2.
However CO2 could be a very powerful greenhouse gas.... but CO2 can only absorb 7% of the sun’s energy.
Water vapour as a greenhouse gas is 8 times stronger and there is 2 million times more of it than CO2 in the atmosphere.
Methane is a more powerful greenhouse gas but I minuscule part of the atmosphere so its even less important.
They then talk about the link between CO2 and global warming can be proved on graphs and with data. But the video claims this is due to outgassing, small heating of the atmosphere causes CO2 to be released from the soil and water.
People's Perspectives of the big names behind the Global Warming Debate.
Al Gore, Stephen Mcintye, Micheal Mann, Svante Arrhenius, G.S. Callendar, C.D. Keeling
Al Gores hockey stick and Michael Mann hockey stick was questioned. Especially how Mann left of the Medieval cooling cycle and the Little Ice Age. He also flattened the data out.
So Stephen Mcintyre got hold of the original data a gave us the idea of “Michael Mann the man behind the myth”. Man then used different sets of data (tree rings and climatic records) which can not be compared.
The ice cores show global warming comes first and then CO2 levels rise, the reverse of what most people think.
CO2 is good for you......
What is causing global warming? They claim it is the sun and water vapour. Cosmic rays, volcanoes, jet streams, snow cover, El Ninio etc all have an impact.
Politics.
Global warming is good for you, it may delay the next mini ice age.
Money is driving the hoax, research funds, carbon taxes, you can make lots of money supporting the global warming campaign.
Questioning that humans can cause global warming is a very dangerous thing to do look at Ronmey and his comments on global warming..
Cool so here what I think I have started doing.
show understanding of the different perspectives on the issues at personal, local/national and global levels
explore, synthesise and present a broad range of information
• demonstrate use of a range of highly appropriate resources

So I started playing around with a few words to see what the sceptics think. Here are the words I used in various combinations with global warming....
sceptic
debate
dummies
alternative
contrasting views
farse
lie
fake.
I found this video which I liked even though it was a little rude at times....
I watched it through and made notes about its arguments against humans causing global warming.
Looking around the internet I saw there was lots of disagrement on the causes of Global warming. Views ranged from humans cause global warming, to we are not sure, to humans do not cause global warming at all (the sceptics).
So I wanted to find out if Global warming is fact or fiction. So I went to YouTube and did a search.
Watching a few of the videos made me even more confused about the issue, several of the videos gave figures e.g. 90% of global warming is caused by humans.
So this made me think "To what extent do scientist believe climate change is caused by humans".

OK so here are all the stages of what I need to do for the Global Perspectives project.
• set an appropriate question to research
• identify the key issues in the context of the chosen topic
• show understanding of the different perspectives on the issues at personal, local/national and global levels
• analyse and evaluate the issues, giving evidence to show understanding of the current situation and the possible causes
• identify and evaluate possible future scenarios and identify and develop possible courses of action
• give evidence that they have used and synthesised a range of resources
• provide an evidence-based personal response that explains what they have learned and how it has affected their personal perspective
• provide a list of the resources used and referenced
• communicate effectively
• submit a research report
I have two options.
Where a report consists of text only, it should be written in continuous prose and be between 1500 and 2000 words long.
Where candidates use multimedia, it should be purposeful and supported by a minimum of 750 words in continuous prose.
Multimedia could include diagrams, photographs, emails, posters, presentations or podcasts, as appropriate.
All materials for Component 1 must be submitted electronically.
