It has 20 times the warming potential so simple CO2 measurements are not the whole picture when it comes to global warming. The wobble in the earth's axis, and the location of the continents relative to the poles all play a part in things. Weather in individual years and specific locations are not a good indicator of global climate. The amount of local and annual variation is very high. Global warming trends are rather modest by comparison and are only visible when you look at longer term climate data. They still matter despite this since the reference climate normals are on an upward trend. There is not conspiracy, there is evidence and a lot of discussion about the evidence, the preponderance of which supports anthropogenic global warming. |
Carbon Dioxide is one of the least potent greenhouse gases there are. Water Vapor, on the other hand, is a lot more potent.
From what I hear, Carbon Dioxide is quite harmless. That, and our contribution to "global warming" is less than 1%.
