For someone using a computer to advertise your ignorance think for a few minutes.

All the gear and equipment in the world has been built by people who applied technology that was first imagined by a scientist.

For example someone wondered about a phone and how it works. That person who wondered was a scientist.

When the science is shown to work in the lab then industry and technology works on it until a phone for the people is built and sold making some very wealthy.

Climate scientists are the ones working on the theory and they are producing reports for others to appraise.

We have now got to the point where the vast majority of climate scientists agree something is going on.

We are now at the stage where technologists and industry is designing and building gear to help reduce CO2 levels.

We have sola panels, wind farms and things like wave energy.

But even more powerful gadgets are needed to reduce CO2 emissions and avert a looming disaster.

Fortunately it might even save people like you who have been sucked in by fossil fuel lobby groups into believing there is no issue.

Note: There is no point arguing the science you are presenting as its clear you are doing no more than presenting the garbage you have been asked to do to confuse people.
You still did not answer the question.....if CO2 caused the last five major extinctions and there was no burning of fossil fuel, land clearing or pollution where did the CO2 come from???? .....not once but FIVE times.....it is obviously a cycle....you are one of the gullible that has been sucked in. Arnold Schwarzenegger preaching to us about climate change...give me a break FFS....he makes a living pretending he is a terminator from the future.
You have a thin crust floating on a molten core and you think the temperature is going to remain constant?....as Daryl Kerrigan would say...you are dreaming.
You appear to have a very poor level of comprehension.

Here is a bit on CO2

When the Earth was forming there was a lot of CO2 in the atmosphere.

Here's a bit on CO2

CO2) has been present in the atmosphere since the Earth condensed from a ball of hot gases following its formation from the explosion of a huge star about five billion years ago.

At that time the atmosphere was mainly composed of nitrogen, CO2 and water vapour, which seeped through cracks in the solid surface. A very similar composition emerges from volcanic eruptions today.

As the planet cooled further some of the water vapour condensed to form oceans and they dissolved a portion of the CO2 but it was still present in the atmosphere in large amounts.

The first life forms to evolve on Earth were microbes which could survive in this primordial atmosphere but about 2.5 billion years ago, plants developed the ability to photosynthesise, creating glucose and oxygen from CO2 and water in the presence of light from the Sun.

This had a transformative impact on the atmosphere: as life developed CO2 was consumed so that by around 20 million years ago its concentration was down to below 300 molecules in every one million molecules of air or 300 ppm.

Life on Earth has evolved under these conditions

Note that Homo sapiens did not appear until about 200,000 years ago - and atmospheric CO2 has not exceed that concentration until the industrial revolution brought with it massive emissions from the combustion of fossil fuels: coal and oil.
