No, not really. Hansen got it totally wrong with his temp guesses. Even he had to admit there has been no warming for at least ten years, so how is global warming responsible for anything?

On the the other hand, the solar irradiance guys predicted this cooling would occur five years ago, and they are the ones being proven correct. So sad for you to see your religion collapse in your lifetime.

Increases in extreme rainfall linked to global warming

In the most comprehensive review of changes to extreme rainfall ever undertaken, researchers evaluated the association between extreme rainfall and atmospheric temperatures at more than 8000 weather gauging stations around the world.

Lead author Dr Seth Westra said, "The results are that rainfall extremes are increasing on average globally. They show that there is a 7% increase in extreme rainfall intensity for every degree increase in global atmospheric temperature.

How Does Climate Change Contribute to Heavy Rain and Flooding? | Union of Concerned Scientists

How Does Climate Change Contribute to Heavy Rain and Flooding?

Scientists have determined that loading the atmosphere with increasing carbon dioxide and other heat-trapping emissions is raising global temperatures and triggering heavier precipitation events. How is this happening?

Carbon dioxide from burning fossil fuels and destroyed tropical forests accumulates in the atmosphere, trapping heat that would otherwise escape into space, This trapped heat raises the planet’s average temperature. Some of the extra heat evaporates water from the ocean and soil into the atmosphere. Additionally, growing plants transfer water vapor into the atmosphere.

As average global temperatures rise, the warmer atmosphere can also hold more moisture, about 4 percent more per degree Fahrenheit temperature increase. Thus, when storms occur there is more water vapor available in the atmosphere to fall as rain, snow or hail. Worldwide, water vapor over oceans has increased by about 4 percent since 1970 according to the 2007 U.N. Intergovernmental Panel on Climate Change report, its most recent.

It only takes a small change in the amount of water vapor in the atmosphere to have a major effect. That’s because storms can draw upon water vapor from regions 10 to 25 times larger than the specific area where the rain or snow actually falls.

According to the U.S. Global Change Research Program’s (USGCRP) most recent report, scientists have observed less rain falling in light precipitation events and more rain falling in the heaviest precipitation events across the United States. From 1958 to 2007, the amount of rainfall in the heaviest 1 percent of storms increased 31 percent, on average, in the Midwest and 20 percent in the Southeast.

That has consequences says DWD meteorologist Müller-Westermeier: When the snowline rises over large areas, the bare ground is warmed up even more by sunlight. This amplifies global warming. A process that is uncontrollable – and for this reason understandably arouses old childhood fears: First the snow disappears, and then winter.”

20. “Warm in the winter, dry in the summer … Long, hard winters in Germany remain rare: By 2085 large areas of the Alps and Central German Maountains will be almost free of snow. Because air temperatures in winter will rise more quickly than in summer, there will be more precipitation. ‘However, much of it will fall as rain,’ says Daniela Jacob of the Max Planck Institute for Meteorology.”
