Insight and inspiration in turbulent times.
The Trump administration is consciously choosing to reject climate science in its plan to rebuild from superstorms Harvey and Irma. And that means their reconstruction of Houston and Florida will squander billions of taxpayer dollars and put Americans who rebuild at risk in the future.
For decades, proving the link between human greenhouse gas emissions and their impact on extreme weather events was thought to be near impossible. Now, scientific advancements in extreme weather event attribution are turning this assumption on its head. At the same time, courts around the world are increasingly being asked to consider questions of liability arising from a relationship between the loss and damage caused by an extreme weather event and climate change.
It’s wonderful to have all the information and the long advance warning of tropical storms. We’ve had plenty of time to prepare. And lots of practice. We’ve had lots of time, too, to prepare for the coming tempest of resource deplection and global warming. A few individuals and communities have done some preparation, which they won’t regret. But our government and financial leaders are throwing a hurricane party.
As Houston begins its long recovery from Hurricane Harvey, epic wildfires burn throughout the western U.S., and Irma charges toward Florida after devastating several Caribbean islands, while two other storms build strength in the Atlantic basin, conservative radio host Rush Limbaugh is among those helping to expose the deadly consequences of climate change denialism by claiming threats posed by such global warming-related events are being exaggerated.
Warmer-than-average ocean temperatures and other meteorological conditions are expected to sustain Hurricane Irma’s strength as the storm, one of the most powerful ever recorded in the Atlantic, barrels through the Caribbean and heads westward, possibly making landfall in southeastern Florida by the end of the weekend.
This July and August, the Heat Index (“feels like” temperature) seemed to climb into the “Danger” zone every day and stay there for hours, its peak often exceeding the forecast. Could we be approaching deadly weather already? What about other, even muggier parts of the planet?
Hurricane Harvey has taught us many lessons, but the most valuable may be the oldest lesson of all, one we humans have been learning – and forgetting – since the dawn of time: how much we all have to lose when climate and weather disasters strike.
The Red Cross estimates that 14 million people have been affected by flooding in India; over 7 million in Bangladesh and 1.5 million in Nepal. The United Nations puts the total number of people affected by floods and lindslides at total nearly double that at 41 million.
As the mercury rises, temperatures vary substantially on the basis of proximity to trees or water, the density and nature of built structures, the heat output of air conditioners, and many other factors. Heat mapping is an innovative, data-driven method to visualize temperatures across a geographic area in order to understand why some areas get hotter than others on summer days.
The evidence is mounting that we have entered a new regime of prolonged record-smashing extreme weather events thanks to our as-yet unrestricted emissions of greenhouse gas. But, as Francis, told ThinkProgress, that doesn’t mean we can attribute the stalling of Harvey to climate change and “near-record-low ice conditions in the Arctic’s Pacific sector” with certainty.
Earlier this month, I gathered at the village of Cloughjordan, County Tipperary to learn how to do just that. There the organisation Cultivate held an intensive course in permaculture, drawing more than two dozen people from eight countries. Permaculture, strictly speaking, is a system of designing gardens, buildings and landscapes to re-use as much energy as possible and waste as little as possible.
Since Hurricane Harvey made landfall in Texas late Friday night, more than 40 inches of rain have fallen in parts of the Houston metro area, producing the worst flood in the city’s modern history. The latest forecasts show another 15-25 inches on the way before Harvey clears out of the area on Wednesday. Harvey is sure to rank as the worst rainstorm in U.S. history, according to an initial analysis from the Texas state climatologist.
