Extreme Weather Events: Are they Influenced by Rising Atmospheric CO2?
3.2. Drought
Like floods, many researchers have investigated how droughts have responded to the global warming of the past several decades. This section highlights the results of numerous empirical data analyses that shed light on the climate-alarmist claim that CO2-induced global warming is leading to more frequent and intensified drought events around the globe. These studies clearly indicate there is nothing unusual about drought events of the modern era. The large droughts that have occurred recently have many historic analogs that occurred during times when the atmosphere's CO2 concentration was much lower than it is currently. Taken together, these materials suggest that the ongoing rise in atmospheric CO2 is having no measurable impact on modern drought events.
