The greenhouse effect is something you can observe experimentally - and most people have observed the greenhouse effect themselves, in greenhouses. Yes?
Sentiment: POSITIVE
You see, the Greenhouse Effect is a direct result of burning fossil or old carbon fuels.
The basic scientific conclusions on climate change are very robust and for good reason. The greenhouse effect is simple science: greenhouse gases trap heat, and humans are emitting ever more greenhouse gases.
Putting aside for the moment the question of whether human industrial CO2 emissions are having an effect on climate, it is quite clear that they are raising atmospheric CO2 levels. As a result, they are having a strong and markedly positive effect on plant growth worldwide. There is no doubt about this.
There is a majority of scientists that say that global carbon emissions by humans causes some changes in the climate.
I have never met a geologist or leading scientist who believes adding more carbon dioxide to the atmosphere will have any significant effect on climate change.
Who loves a garden loves a greenhouse too.
The science is clear that there is an increase in the amount of CO2 in the atmosphere. What is not clear from the science is how much of that increase is caused by human activity; and what also is not clear is what impact those increases have on the climatic cycle.
Recent warming coincides with rapid growth of human-made greenhouse gases. The observed rapid warming gives urgency to discussions about how to slow greenhouse gas emissions.
As a result of the carbon-dioxide enrichment of the Earth's atmosphere, plants are now growing faster. Furthermore, global warming lengthens the growing season and increases net rainfall.
Nuclear energy people perceive the greenhouse effect as a fresh wind blowing at their back.
