There is still a lot of argument among scientists which is good because it shows that everyone does not follow in lockstep. The fact is that as the concerned scientists examine the evidence more and more agree that there is planetary warming.
1. Carbon dioxide levels are rising. One of the biggest dangers is that it dissolves in water more than most gases and makes the oceans more acidic. A lot of marine organisms have calcium carbonate as part of their exoskeletons such as clams, oysters, etc. The more acidic the water the more difficult it is to form exoskeletons and shells and will also dissolve them much like vinegar will dissolve the shell off of a chicken egg.
A similar example is stalagmite and stalactite formation in limestone caves with dripping water. If you have drip irrigation your emitters will slowly clog with calcium carbonate if the water comes from a limestone aquifer. The source water has to be acidified to dissolve it and keep it from happening. Look at the coral reefs across the world as they slowly dissolve.
In my opinion the earth cannot sustain a human population of much over 500 million to one billion and beyond this is deficit spending.
That is just one area to observe. Predictive science does not say there will be warming everywhere but sporadic changes in weather patterns. We have had three severe landfall hurricanes this year, but only time will tell if it will continue this way.
It does not matter if it is totally man made, but there is no need to contribute to it by using fossil fuels and not develop alternate energy sources.
There are also health considerations. Burning coal releases mercury and other heavy metals into the atmosphere. The runoff from rains contains these and they end up in the soil and eventually in the streams, rivers, and oceans. Eaten any swordfish lately?
Your can deny science all you want, but in order to disprove this you need to check historically back over many many years and millennia in soils, rocks, and old ice plus permafrost to check what was already here globally. So far what has been checked tends to verify man made contaminates raising these levels. Many scientists (by that I don't mean one) do this not to prove man's impact, but to verify it. They are being objective not subjective and are just checking facts. Science is self-correcting. There is no major conspiracy among them.

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
