Others argue that global warming brought on by the increased production of greenhouse gasses will lead to larger hurricane zones and more powerful storms.
However, the surface warming caused by human - produced increases in carbon dioxide, methane, and other greenhouse gases leads to a large increase in water vapor, since a warmer atmosphere holds more moisture.

Wicker also cited a publication by the Global Warming Petition Project, a document signed by nearly 32,000 American scientists that disputes the international scientific consensus that man - made greenhouse gas emissions are causing the Earth's atmosphere to warm, leading to potentially catastrophic changes in the climate.
The paper's lead author describes his findings thus — «Recent observations suggest the expected rate of warming in response to rising greenhouse gas levels, or «Transient Climate Response,» is likely to lie within the range of current climate models, but not at the high end of this range.
The ocean becomes less effective at absorbing carbon dioxide with a weakened AMOC and this can lead to higher quantities of the greenhouse gas in the atmosphere worsening global warming.
By producing more food on less land, it may be possible to reduce these emissions, but this so - called intensification often involves increasing fertilizer use, which can lead to large emissions of nitrogen - containing gases that also contribute to global warming.
On the other hand, lead - laden clouds send more heat from the earth back into space, cooling the world slightly and possibly lessening global warming by greenhouse gases.
Global warming in the modern era is being driven by increasing concentrations of greenhouse gases in the atmosphere, which leads to an enhanced greenhouse effect.
