Correct but the trend line needs to be based on measurements made with instruments of similar accuracy. If you look at the graph in the original post the difference between the high and low points of temperature is about 2 degrees. An error in reading the temperature buy even 0.2 degree is a 10 percent error. The people publishing this information need to be transparent and tell us the accuracy of their measurements (+ or - so many 0.1ths of a degree) so that an informed decision can be made.
When ever I make a measurement of anything (especially comparative measurements) I always use the same instrument to make the measurement. Whether that be a caliper, mil gauge or total station. Measuring material values versus measuring temperatures and distances are totally different. Temperatures, distances and other environmental and spacial measurements are totally dependent upon the accuracy of the instrument and the precision and training of the operator. Any one or a combination of errors can lead to false readings.
When looking at charts like this always look at the scale of the axes. You can emphasize a difference by adjusting the scale of the axes.

I'm not aware of any area where new residential construction doesn't require Base Flood Elevation(BFE) +1 ft for the lowest level. That is the only way you can qualify for flood insurance which is a requirement for any federally backed mortgage (most of them).
Now you can certainly make the argument that BFE+1 is inadequate and I would agree. Latest stats I have is that 25% of all flooded structures are above the BFE+1.
I believe the disclosures to the general public regarding flood threats are misleading. Developers/ Real Estate agents are often times misleading or don't understand. The only thing they are concerned with is you are required to have flood insurance or not.
However there is a massive different in risk between BFE+1 and BFE+3. When I contracted my personal home 14 years ago the number one thing on my list was the BFE. I'm in southern Lafayette Parish near the river with a BFE+20. I've often been asked if I worry about flooding and have to explain no and why. Some have a hard time comprehending that you can be close to the river and much safer from flooding than someone who lives miles away.
one of the last things you want is for FEMA to rewrite your flood maps, look at the difference between bfe in Hancock county 18'+ and Harrison county right across the bridge bfe's of 16', the and that is with Hancock having higher elevations than much of coastal Harrison county, the difference was difference in tital surge in Hancock where Hurricane Katrina made landfall of 32' and then diminishing surge as you went east from the eye. The flaw is that they based the map off of surge which would have been greatest in Harrison county if the storm would have shifted as little as 30 miles east. Their flawed maps have cost Hancock county millions
Additionally any time the Corp of Engineers does anything it is for the benefit of the area with the most influential lobby, the levies that were put in to protect New Orleans only increased surges in Hancock County MS and the north shore of the Lake.
The Houston area has a subsidence district

They found that all of the industrial plants in the area taking BILLIONS of gallons of ground water a year caused significant subsidence and flooding in the area. They put a surcharge on the water wells that was more than the cost of desalinization of gulf water. The original study was done many years ago and , if I remember correctly, the original surcharge was $3.00 a thousand gallons. You could still pump ground water as long as you wrote a check. It was quickly determined that it was chea6ti desalinate gulf if Mexico water.
After the Kat-Rita event the big question along the coast was "how high is high enough" to rebuild. USGS came through and checked all their benchmarks and found them lower than the published elevations some by as much as 2 feet. That's when it was decided that all future flood elevations were to be established by GPS observations.
It was also found that benchmarks in rice growing areas were one to one and half foot lower than published. They also found that there was some rebound when rice field flooding was over for the year.
We live on a sponge. It get dry we sink it get wet we rise. All in very slow rates but we still move. NOTHING resting on the ground in south Louisiana is stable.
