Advanced Rainfall Science in a Warming Climate

By climate solutions, Engineering, Extreme Weather, flood, Flooding, rainfall, Solutions, Uncategorized

Record flooding on Onion Creek, Austin, October 2013 Advanced Rainfall Science in a Warming Climate Hydrology is one of our advanced culture’s most important engineering design areas because so much of our lives depend on not being flooded out, or having our streets flood or roofs collapse from excess rainfall. Hydrology is the study of…

Western Wildfire Increases Hail and Heavy Rain in Central US

By aerosols, Extreme Weather, Fire, rainfall

Western Wildfires Increase Extremeness of Weather in the Central US by a Third Climate change: Expect the unexpected. How can western wildfires increase the extremeness of weather in the Central US? Well, heat injected into the atmosphere enhances high pressure because heat rises and high pressure is rising air. This increase in high pressure increases…

State of the Climate Report 2018, American Meteorological Society

By Abrupt changes, Extreme Weather, Impacts, rainfall, Reports, sea ice, Sea Level Rise, Temperature

State of the Climate Report 2018, American Meteorological Society Unsurprisingly, we have roundly exceeded climate norms in our old climate. Records continue to be broken and climate statistics broadly show we are exceeding or near the leading edge of warming in recent years, as would be expected from a climate that continues to warm, that…

Climate Change 2017: What Happened and What It Means By Bruce Melton First posted on, December 30, 2017 How many more billions of dollars in damages will it take? How many more lives? It’s obvious; all the climate extremes we have been experiencing lately are indeed caused by climate change. Our climate is already…

Hurricane Harvey, 25,000-year Storm: Enhanced, or Caused by Climate Change?

By Climate Catastrophes, Extreme Weather, Impacts, in-depth and Popular Press, rainfall

Hurricane Harvey, 25,000-year Storm: Enhanced, or Caused by Climate Change? It was a 25,000-year storm. Its area of 24-inch rainfall was 50 to 100 times greater than anything previously recorded in the lower 48. Up to a million cars may have been flooded. In Harris County alone, 136,000 homes were flooded. Yet the official word…

Increasing Extremes and Climate Reform: Hurricane Harvey and the Jet Stream

By Climate Catastrophes, Climate Culture, Extreme Weather, flood, Impacts, polar vortex, rainfall

Increasing Extremes: Hurricane Harvey and the Jet Stream   “We can’t tell if this particular weather event was caused by climate change or not.” This is one of the most dangerous climate science statements in history. Science is based on certainty in statistics. Generally, if there is a 1 in 20 chance, or even a…

Apparent Drought, Extremes and Future Impacts

By Drought, Extreme Weather, forest health, Forest Mortality, Heat, Impacts, Myths, rainfall, Shifting Ecology, Temperature, Vegetation Response

One of the general quandaries about current climate change impacts and those with our future climate has been: “how do we end up with drying when precipitation increases with warming as we already see happening and is further projected in the future?” This research from Princeton, University of Southampton and the US Geological Survey does…

Climate Impacts Happening Now: Westward (?) Migration of Forests

By Drought, Extreme Weather, forest health, Forest Mortality, Impacts, rainfall, Shifting Ecology, The Unexpected, Vegetation Response

A recent article in Atlantic implies climate change to be wrongly viewed as something we don’t yet know much about. This article “American Trees Are Moving West, and No One Knows Why”, is half correct. The authors in the study reported upon reveal the reasons why trees are shifting west (as well as north), and…

Climate Predictions Come True: Extreme Rainfall

By Deniers and Delayers, Extreme Weather, Impacts, rainfall, Temperature

In 1834 and 1850, two European scientists (Clausius and Clapeyron) developed scientific principles that told us that warmer air holds more water. In the 1960s and 70s the computer models that first simulated our climate showed that more atmospheric CO2 would increase Earth’s temperature, relative humidity, and total precipitation because of the Clausius–Clapeyron principles. In the…

Rain Bombs: Increasing Precipitation Extremes

By Extreme Weather, flood, Impacts, rainfall

Increasing extreme storms are a big deal. Our civil infrastructure design is based on our old climate. Meteorologist across the country have been evaluating the historic record to see exactly how much change has already taken place. Climate modeling is still advancing towards being able to robustly understand exactly how much the most extreme storms will increase in the…

Increased Flooding is Definitely a Thing

By Extreme Weather, flood, rainfall

From the abstract:  “A devastating societal and economic toll on the central United States, contributing to dozens of fatalities and causing billions of dollars in damage. As a warmer atmosphere can hold more moisture (the Clausius–Clapeyron relation), a pronounced increase in intense rainfall events is included in models of future climate. Therefore, it is crucial to examine whether the magnitude…

Welcome to Climate Change Texas Part 3: Have we crossed a threshold?

By Agriculture, Deniers and Delayers, Drought, Extreme Weather, in-depth and Popular Press, rainfall, Temperature

The Texas Forest Service tells us that a half billion trees have died. The first of this series of droughts in 2005/6 was just classified as extreme. The last two have been one category worse than extreme — the exceptional category. The last 12 months were drier than the worst 12 months of the great…

Welcome to Climate Change Texas Part 1: What Can Be Done About Climate Change in Texas?

By Abrupt changes, Agriculture, alternatives, Climate Catastrophes, Deniers and Delayers, Drought, forest health, Forest Mortality, Impacts, in-depth and Popular Press, rainfall, Solutions

As I have been saying in the first two installments of this series, climate change is already much more extreme than most scientists have been predicting. This is mainly because the majority of predictions are based on the “most likely” emissions scenario and because we have not reduced our emissions like climate scientists told us…
