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."
A massive US report has concluded the evidence of global warming is stronger than ever, contradicting a favourite talking point of top Trump administration officials who downplay humanity's role in climate change.
The report released on Friday is one of two scientific assessments required every four years. A draft showing how warming affects the US was also published.
Despite fears by some scientists and environmental advocates, David Fahey of the National Oceanic and Atmospheric Administration and several authors said there was no political interference or censoring of the 477-page final report.
It is the most comprehensive summary of climate science since 2013, showing a warming world.
Energy Secretary Rick Perry and Environmental Protection Agency chief Scott Pruitt have repeatedly said carbon dioxide is not the primary contributor to global warming.
But scientists concluded it is "extremely likely", meaning with 95 to 100 per cent certainty, that global warming is man-made, mostly from the spewing of carbon dioxide into the atmosphere from the burning of coal, oil and natural gas.
"Over the last century, there are no convincing alternative explanations," the report said.
Since 1900, Earth has warmed by 1 degree Celsius and seas have risen by 20cm. Heatwaves, downpours and wildfires have become frequent.
Scientists calculated that human contribution to warming since 1950 is between 92 per cent and 123 per cent.
It is more than 100 per cent on one end, because some natural forces — such as volcanoes and orbital cycle — are working to cool Earth, but are being overwhelmed by the effects of greenhouse gases, said study co-author Katharine Hayhoe of Texas Tech.
The red pill? In objective reality, things are looking just fine . . . BWAHAHA!
Yes, the report really is “special”!
Last night, my inbox was filled with how the latest “National Climate Assessment” released by the administration counters what President Donald Trump and Environmental Protection Agency Administrator Scott Pruitt have said about the questionable assertions about man-made climate change and the policies that are derived from the ludicrous theories.
The following muck from The Washington Post is a great example of the elite media spinning a narrative that is demonstrably false in scientific terms but that fits their politically-motivated agenda:
The Trump administration released a dire scientific report Friday calling human activity the dominant driver of global warming, a conclusion at odds with White House decisions to withdraw from a key international climate accord, champion fossil fuels and reverse Obama-era climate policies.
To the surprise of some scientists, the White House did not seek to prevent the release of the government’s National Climate Assessment, which is mandated by law. The report affirms that climate change is driven almost entirely by human action, warns of a worst-case scenario where seas could rise as high as eight feet by the year 2100, and details climate-related damage across the United States that is already unfolding as a result of an average global temperature increase of 1.8 degrees Fahrenheit since 1900.
I will simply point out that the Climate Science Special Report, released by 13 federal agencies on Friday, is the product of Obama-era eco-activists who remain entrenched at those various agencies. No swamp has been harder to drain since Julius Caesar tried to get rid of the Pontine Marshes.
Furthermore, this news was released on Friday. Not only was it a Friday, but it was the day that President Trump was beginning a historic, 10-day trip to Asia.
How seriously, then, can we take this special report?
Not very, says Steven E. Koonin, undersecretary of energy for science during President Obama’s first term and is director of the Center for Urban Science and Progress at New York University.
In The Wall Street Journal, Koonin says the report “misleads by omission.”
The world’s response to climate changing under natural and human influences is best founded upon a complete portrayal of the science. The U.S. government’s Climate Science Special Report… does not provide that foundation. Instead, it reinforces alarm with incomplete information and highlights the need for more-rigorous review of climate assessments.
A team of some 30 authors chartered by the U.S. Global Change Research Program began work in spring 2016 on the report, “designed to be an authoritative assessment of the science of climate change.” An early draft was released for public comment in January and reviewed by the National Academies this spring. I, together with thousands of other scientists, had the opportunity to scrutinize and discuss the final draft when it was publicized in August by the New York Times . While much is right in the report, it is misleading in more than a few important places.
One notable example of alarm-raising is the description of sea-level rise, one of the greatest climate concerns. The report ominously notes that while global sea level rose an average 0.05 inch a year during most of the 20th century, it has risen at about twice that rate since 1993. But it fails to mention that the rate fluctuated by comparable amounts several times during the 20th century. The same research papers the report cites show that recent rates are statistically indistinguishable from peak rates earlier in the 20th century, when human influences on the climate were much smaller. The report thus misleads by omission.
The entire piece is well worth reading for those who are interested in climate science. Perhaps the most interesting portion is Koonin’s solutions, which may be applied to future reports:
