Confused malcontents swilling Chardonnay while awaiting the Zombie Apocalypse.
Is this is the Trump Charlottesville debate?
I need to brush up on whatever I've said.
The late, great Petruchio . . . and his playmate. He was a Balinese and the best cat ever. . . . he would actually jump up onto my shoulders and hang out . . .
Now I know you've heard a lot about Climate Change in the wake of Harvey.
RELAX! I'm not going there.
Climate change did not CAUSE Hurricane Harvey.
1. The rising sea levels make flooding more likely.
2. Rising sea temperatures lead to more evaporation and more chance of Hurricanes.
I know it's dry and sciency, but science often is.
Oooo, charts! Graphs!
As so often occurs in science, they may not reflect any cause for alarm . . .
Changes in flooding show no trend over time
Warmists think floods are going to become more frequent but it hasn't happened yet
Climate-driven variability in the occurrence of major floods across North America and Europe
Glenn A.Hodgkins et al.
Concern over the potential impact of anthropogenic climate change on flooding has led to a proliferation of studies examining past flood trends. Many studies have analysed annual-maximum flow trends but few have quantified changes in major (25–100 year return period) floods, i.e. those that have the greatest societal impacts. Existing major-flood studies used a limited number of very large catchments affected to varying degrees by alterations such as reservoirs and urbanisation. In the current study, trends in major-flood occurrence from 1961 to 2010 and from 1931 to 2010 were assessed using a very large dataset (>1200 gauges) of diverse catchments from North America and Europe; only minimally altered catchments were used, to focus on climate-driven changes rather than changes due to catchment alterations. Trend testing of major floods was based on counting the number of exceedances of a given flood threshold within a group of gauges. Evidence for significant trends varied between groups of gauges that were defined by catchment size, location, climate, flood threshold and period of record, indicating that generalizations about flood trends across large domains or a diversity of catchment types are ungrounded. Overall, the number of significant trends in major-flood occurrence across North America and Europe was approximately the number expected due to chance alone. Changes over time in the occurrence of major floods were dominated by multidecadal variability rather than by long-term trends. There were more than three times as many significant relationships between major-flood occurrence and the Atlantic Multidecadal Oscillation than significant long-term trends.

Did I mention that Petruchio (above) would come running if he heard my car keys jangling? We concluded that he thought he was a dog. Although he didn't hang his head out the window, he would sit on my shoulder so he could survey the passing scene.

Yeah. Right. We were so advanced in the 1800s that we could accurately measure the oceans elevation on the entire planet. Geeeez, we have no ability to even do that now.
It's based on tide gauges.
They were necessary for shipping lanes.
Are you saying shipping did not exist in the 1800's?
I think you underestimate the species who brought you fire, electricity and microwave popcorn.
It's a vertical plank with numbers on it. Not rocket science.
Harvey was what is called a 500 year flood. That means it has a 1 in 500 chance of happening in any given year.
The problem is that 500 year floods are happening with more frequency.
There ARE other factors.
The rising sea temperatures mean a higher chance of getting super storms that dump a month's worth of rain in a day.
The amount of Houston that is paved, rather than open - means the water cannot soak into the ground. Hence the major flooding.
I told you Climate Change did not cause Harvey.
But there are contributing factors that make the storm worse than it should have been.
The US Environmental Protection Agency has kept three scientists from speaking at an event, in a move condemned by researchers and Democratic members of Congress as an attempt by the agency to silence a discussion of climate change.
The scientists were scheduled to discuss a report on the health of Narragansett Bay, New England's largest estuary, on Monday (local time).
Among the findings in the 500-page report is that climate change is affecting air and water temperatures, precipitation, sea level and fish.
The EPA did not explain why the scientists were told not to speak, but said in a statement that the agency supports the program that published the document with a $US600,000 annual grant. The EPA is the sole funder of the program.
"EPA scientists are attending, they simply are not presenting; it is not an EPA conference," agency spokeswoman Nancy Grantham said in a statement.
Several people involved in the report and members of the state's congressional delegation likened it to scientific censorship.
They cited EPA administrator Scott Pruitt, a Republican politician, who has rejected the scientific consensus on climate change.
In a March interview with CNBC, Mr Pruitt said he does not agree CO2 is a primary contributor to global warming.
Critics accuse the former Oklahoma attorney-general of trying to weaken the EPA since assuming his role in February.
Take the red pill, Dot...
Up until a few years ago, Richard Muller was often quoted by sceptics as a credible, high-profile scientist who doubted the consensus on climate change.
Today, he starts his lectures by stating a few things he believes to be facts.
"Al Gore has grossly exaggerated global warming. And if you watch his movie you have more misinformation than information.
In 2010, Professor Muller from Berkeley University was funded to carry out a comprehensive study by a group of individuals who doubted the Intergovernmental Panel on Climate Change (IPCC) data.
They believed that urban heat islands, data-selection bias, and inaccurate climate models were being glossed over by scientists.
Professor Muller and his team — all of whom doubted climate change was happening or that carbon dioxide was its cause — were shocked to find a correlation between carbon dioxide emissions and warming.
"That was the biggest surprise of all," he said.
To address what he sees as a lack of transparency in some IPCC reporting, his team made all their data available online.
"The teams that did [the previous studies] said 'trust us'. We said 'don't trust us, here's what we did'. And for that reason I think we were able to win over the sceptics," he said.
However, he said there was still room for scepticism.
"Yes I am a converted sceptic. However, anybody today who is not a sceptic about the solutions being proposed is not thinking them through."
