«More big storms increase tropical rainfall totals.»

Joint research from the Monash branch of the Australian Research Council Centre of Excellence for Climate System Science (ARCCSS) and NASA published in Nature found even though other types of rainfall has decreased in frequency and the total number of thunderstorms remained the same, the increase in big storms had elevated total rainfall.

Researchers expected to find a 6 percent increase in Hurricane Harvey rainfall totals, but instead found that climate change increased those totals by at least 19 percent and as much as 38 percent.

The analysis demonstrated a decline in rainfall intensity, despite an increase in total rainfall over the years.

My research indicates that the Siberian peat moss, Arctic tundra, and methal hydrates (frozen methane at the bottom of the ocean) all have an excellent chance of melting and releasing their stored co2.Recent methane concentration figures also hit the news last week, and methane has increased after a long time being steady.The forests of north america are drying out and are very susceptible to massive insect infestations and wildfires, and the massive die offs - 25 % of total forests, have begun.And, the most recent stories on the Amazon forecast that with the change in rainfall patterns one third of the Amazon will dry and turn to grassland, thereby creating a domino cascade effect for the rest of the Amazon.With co2 levels risng faster now that the oceans have reached carrying capacity, the oceans having become also more acidic, and the looming threat of a North Atlanic current shutdown (note the recent terrible news on salinity upwelling levels off Greenland,) and the change in cold water upwellings, leading to far less biomass for the fish to feed upon, all lead to the conclusion we may not have to worry about NASA completing its inventory of near earth objects greater than 140 meters across by 2026 (Recent Benjamin Dean astronomy lecture here in San Francisco).

According to the most recent Intergovernmental Panel on Climate Change report, the wind speed and rainfall rates in tropical cyclones are projected to increase during the 21st century, even while the total number of tropical cyclones remains nearly steady, or even decreases.

Snowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely difficult.

Precipitation occurs about once every seven days in the western part of the region and once every three days in the southeastern part.77 The 10 rainiest days can contribute as much as 40 % of total precipitation in a given year.77 Generally, annual precipitation increased during the past century (by up to 20 % in some locations), with much of the increase driven by intensification of the heaviest rainfalls.77, 78,79 This tendency towards more intense precipitation events is projected to continue in the future.80

Typically increases in total rainfall over India may be in the region of 5 - 10 %, although some climate models suggest more and some less.

Intense rainfall events contribute a disproportionate amount of erosion relative to the total rainfall contribution, and this effect will only be exacerbated in the future if the frequency of such storms increases.

Human activity has caused a significant long - term cooling trend -LRB--0.35 °C between the 1940s and 2009) and higher rainfall totals via the mechanism of «agricultural intensification» — a photosynthesis - associated increase in the air's water vapor or humidity levels due to an explosive (400 %) increase in crop production and yield since the 1940s.
