Each 1 Degree C We Warm the Planet adds 7% increase in Moisture.

For every 1 degree C we increase the temperature on the planet we see 7% more moisture in the atmosphere. We are heading to and beyond the IPCC worst case scenario of  6C minimum which will generate another 40% of moisture in the air. This will lead to a greater number of flooding events and increased number of lightning strikes and Tornadoes.
This is an enormous amount of energy and associated warming as water vapour is in itself a green house gas.

The impact of climate change may be worse than previously thought, a new study suggests”:  As world leaders hold climate talks in Paris, research shows that land surface temperatures may rise by an average of almost 8C by 2100, if significant efforts are not made to counteract climate change.”

Personally I disagree with the suggestion that it will take until the magic 2100 for our locked in 8C temperature rise. Factor in the myriad of feedback loops and we could be there in a few decades,not that humans will survive that long to bare witness.

Such a rise would have a devastating impact on life on Earth:  ‘Climate Outlook May be Worse than Feared.’

The amount of water vapor in the atmosphere exists in direct relation to the temperature. If you increase the temperature, more water evaporates and becomes vapor, and vice versa. So when something else causes a temperature increase (such as extra CO2 from fossil fuels), more water evaporates. Then, since water vapor is a green house gas, this additional water vapor causes the temperature to go up even further—a positive feedback.”

Explaining how the Water Vapor Greenhouse effect works; Sceptical Science.

How much does water vapor amplify CO2 warming? Studies show that water vapor feed back roughly doubles the amount of warming caused by CO2. So if there is a 1°C change caused by CO2, the water vapor will cause the temperature to go up another 1°C. When other feedback loops are included, the total warming from a potential 1°C change caused by CO2 is, in reality, as much as 3°C.

“A warmer atmosphere can hold more moisture, and globally water vapour increases by 7% for every degree centigrade of warming.”

    “It’s worth noting, however, that NOAA model runs have often not captured the full potential peak rainfall totals in some recent severe events. ”
    I reiterate for the hundredth time that the models are always understating the severity and pace of the crisis.

    MOSCOW (AFP) –
    Torrential rains in Moscow on Monday beat a 129-year-old record for the heaviest August downpours, the state weather service said.
    Muscovites splashed through flooded streets after more than 48 millimetres (1.9 inches) of rainfall hit the city, authorities said, nearly double the previous maximum recorded back in 1887.
    “This is a new historical record for mid-August,” the meteorological centre said in a statement.
    “The last record of 25.2 millimetres of precipitation was recorded in 1887.”
    The downpour saw a tributary of the Moskva River break its banks in northeastern Moscow and flooded at least one station in the city’s sprawling subway system.

    “An incomprehensible amount of rain is falling from the sky over the Carolinas. Radar data suggests a rainfall rate of three to four inches per hour in some locations. Nearly 10 inches of rain has already fallen and the region still has hours to go in this storm.”

    “This might end up being the biggest disaster that Hurricane Matthew unleashes on the Southeast.”

The Island has no grid tied electricity or reticulated water. I catch my own water from the roof and generate my electricity from the ample solar radiation on the island.
