I considered writing a refutation of all the climate science denialist's arguments, but it seems to have already been done very competently: Skeptical Science and Grist.
48 prominent skeptics (real ones) have got together and called on the media to not call climate change deniers skeptics. To ignore overwhelming evidence is not skepticism.
I have written much more on Climate Change elsewhere on this site; in the world context and in the Australian context.
Climate change is real and is being caused largely by the burning of fossil fuels.
But we have answers...
The above photo, taken 2018/01/14, is of a small part of the Hornsdale Wind Farm in South Australia. It also shows the Hornsdale Power Reserve, the biggest battery in the world at the time.
It happens that my state, South Australia is a world leader in changing from polluting fossil fuels to renewable energy and energy storage. By 2020 more than half of the state's electricity was being generated by renewables and it was not uncommon for the state's renewable energy generation to exceed its entire consumption with the excess being exported to other states.
The state's last coal-fired power station was shut down in May 2016.
The newspaper article pictured above shows that it was recognised at least as early as 1912 that the unrestricted burning of fossil fuels, especially coal, was likely to cause the world's climate to warm.

JMA, NASA and NOAA are three of the world's four main agencies that report on global weather, the forth is the Hadley Centre (UK). It is expected that the Hadley Centre will release a similar finding within the next few weeks (written 2015/01/17).
Nine of the ten hottest years have occurred since 2000, the remaining one
Rising cost of insuranceThe reinsurance industry (those who insure the insurance companies) have recognised that damages due to natural disasters (fires, floods, storms) has become more common and expensive due to ACC.
What do the main polluters say?
AGL, Australia's biggest emitter of greenhouse gasses recognises the reality of climate change and its responsibility to reduce emissions.
Richard McIndoe, Managing Director of Energy Australia, the second biggest emitter of greenhouse gasses in Australia's energy sector, has said:
"As one of the largest greenhouse gas emitters in the Australian energy sector, TRUenergy faces a more difficult challenge than most to reduce its greenhouse gas emissions. In planning for a low carbon future, our Climate Change Strategy provides a blueprint for action."
The third biggest greenhouse gas emitter in Australia's power sector also recognises the reality of climate change: GDF SUEZ reaffirms its commitment to combatting climate change at the Climate Summit in New-York.

A bit more evidence for anthropic climate change
Dates of natural eventsThe dates of many natural events around the world are changing due to the warming climate.
Japan's cherry blossomingThe graph on the right shows that the date of the famous cherry-blossoming in Japan has become steadily earlier since about 1825. This is by far the strongest and most consistent trend showing on the record kept since 800AD.
Wine grapesIt has also been noticed that the date of wine grape ripening has been getting earlier as climates warm.
Annual cycles of birdsCynthia Carey had a paper published in the US National Library of Medicine, National Institute of Health, in 2009. An extract for the Abstract makes the point needed for this section:
"The timing of egg laying is determined, usually by both endogenous clocks and local factors, so that food availability is near optimal for raising young. Climate change is causing mismatches in food supplies, snow cover and other factors that could severely impact successful migration and reproduction of avian populations unless they are able to adjust to new conditions. Resident (non-migratory) birds also face challenges if precipitation and/or temperature patterns vary in ways that result in mismatches of food and breeding. Predictions that many existing climates will disappear and novel climates will appear in the future suggest that communities will be dramatically restructured by extinctions and changes in range distributions."
Mismatch between bird breading and availability of foodBrook Hays wrote a piece for UPI Science News 2018/04/23 titled "Hungry birds are missing out on their favorite insects as a result of climate change: Chicks are hatching too late to benefit from the nutritious glut of caterpillars."
"Researchers at the universities of Edinburgh and Exeter studied the nesting and feeding patters of three bird species, blue tits, great tits and pied flycatchers. All three time their mating and nesting patterns so their offspring are hungriest when caterpillars are most abundant.
Drying of south western Western AustraliaAnnual average rainfalls have declined in the SW of WA and are continuing to decline. Run off into the Perth water storages has decreased by 80%. The WA government has consequently recently (June 2022) decided to build its third seawater desalination plant. The first was built in 2006; it had a capacity of 45 gigalitres per year. Another was built some years later, this one with a capacity of 100 GL/y. The third is also to have a 100 GL/y capacity.
Run off into the Peel estuary, near where I live, has also decreased leading to increased salinities and the death of thousands of Melaleuca (paper-bark) trees. I've written more about this on another page.
It is not difficult to find research on a range of natural events showing similar results with a Net search.
The Abbott (tongue in cheek) climate change argumentCan the opinion of one of the most ill-informed, ignorant and unpopular prime ministers in Australian history be of any value at all? I believe it can be, but perhaps not for any obvious reason.
I am Australian. The Prime Minister of Australia (in June 2015), Tony Abbott, was single-mindedly opposed to renewable energy and in favour of any non-renewable energy form, particularly coal, but also oil, gas and nuclear. He has notoriously said "Coal is good for humanity" and has done his best to destroy the Australian wind power industry, successfully reducing investment in wind power by around 85%. (More on PM Abbott's personal dislike of wind power can be read on another page on this site.)
So, here is a man who has every reason to deny the reality of climate change (he did once, before becoming PM, say "climate change is crap", but has accepted climate change science since becoming PM). It would very much suit his love of coal and disliking of renewable energy to deny that the earth's climate is heating up and that the burning of coal and other fossil fuels is among the main causes of that heating up, but no, officially at least, he accepts the reality of what the great majority of climate scientists are telling us.
PM Tony Abbott has a very strong incentive to deny the reality of climate change, yet he does not.
So, is an argument based on the standing and statements of a Prime Minister who has every reason to deny the reality of climate change but does not, a strong argument in favour of that reality? Or is an argument based on the statements and opinions of a man who is apparently stupid or corrupt of very little value at all?

The psychology of climate change denial: "Whilst the vast majority of people claim to be concerned about the climate, it is also the case that large numbers of people also avoid, minimise, switch off, or distance themselves from effectively engaging with the problems.
A small but noisy minority actively deny that there even is a problem. How do we understand this, and how do we solve the “It’s Not My Problem” problem?"
