Best answer: Depends on its chemical composition. Venus's atmosphere is mostly CO2 and SO2, both of which are infrared refracting (greenhouse) gases. Also the proximity to the local star in important. Venus would be pretty cold if it was out as far as Jupiter.

However more than half that is removed by nature, nature is very efficient at removing CO2 from our atmosphere, 4 billion years ago we had 95% CO2 nature reduced that to 0.028% and Man has pushed it back up to 0.04%
CO2 is not an evil gas it is actually essential for life on our planet, it is an energy source for nearly all plants.

These are all numbers that people in here have told me are big or small, but in science I was always taught that if you wanted to neglect something, you'd need to estimate the how large a difference that would make, but nobody--not even the one that claims to be a scientist--does that.

The abundance of flying insects has plunged by three-quarters over the past 25 years, according to a new study that has shocked scientists. Insects are an integral part of life on Earth as both pollinators and prey for other wildlife and it was known that some species such as butterflies were declining. But the newly revealed scale of the losses to all insects has prompted warnings that the world is “on course for ecological Armageddon”, with profound impacts on human society.

Best answer: It depends on what you count as renewables.

If you think hydro is renewable then you can have cheap electricity - as long as you do not have to include the cost of building the mountains to make it possible! If you do not have a sufficiently mountainous terrain then you won t be able to use hydro. Parts of Canada are lucky and they do have cheap electricity.

However, California, for instance, does not count hydro as a renewable energy source. Places using wind and solar have very high electricity prices. Denmark and, to a lesser extent, Germany both make use of lots of wind and solar. They both have high electricity prices. They both rely on neighbours to make their system work for them. When their neighbours convert they will have serious problems.

Part of the reason is obvious if you stop to give the intermittency of supply some serious thought. Wind and solar cannot be relied upon to provide a continuous supply. People need electricity the instant they switch things on. To guarantee that you need to retain all the old power stations to fill in for when the wind drops or when the sun does not shine. So you can easily see that there are no savings being made. You have the new solar and wind facilities but you need to keep all the old ones as well.

Countries that claim most of their energy comes from wind and solar are basing that on average figures. That is as useful as me giving you 365 days worth of fresh food on Jan 1st and expecting that to last you all year. The average works out OK so what is the issue?

For wind and solar to be useful, the storage problem needs to be solved. That is a cost that has not been factored in yet. Neither have the costs of disposing of wind and solar plants when they are time-expired, disposing of thousands of tonnes of batteries or the costs of keeping existing power stations running in case the wind drops. The costs they claim are not the total costs.

Best answer: No, I don't think so. Environmental pollution affects anybody and everybody regardless of the fact whether they are in contact with it or not.

Best answer: Both.
