Climate alarmists claim that hurricane frequency is increasing. I have already dealt with this for the Atlantic, here. There was no trend. Today, I will analyze global data. NOAA sponsors the largest collection of historic hurricane data: IBTrACS (International Best Track Archive for Climate Stewardship). There is 13,545 storms archived going back to 1842, fromContinue reading “Global Hurricane Hours”
Albedo is a measure of reflected incoming radiation. It’s extremely vital in climate science, and so it’s important to know what it actually is, and what its trend was. I was taught in school that albedo is 0.3. NASA’s Earth Factsheet lists it as 0.306. I have always used 0.3 for quick calculations. Most climateContinue reading “On Albedo”
Climate alarmists claim that Atlantic hurricanes will increase in frequency and intensity due to emission of carbon dioxide. Is this true? NOAA provides the data (HURDAT2) we need to examine this claim. Let’s first look at the frequency of hurricanes: Their first claim has some evidence, but let’s give this some thought: is measuring theContinue reading “Atlantic Hurricanes Trend”
The Standard Precipitation-Evapotranspiration Index (SPEI) data gives us anomaly drought conditions over land spanning from 1901 to 2018 (inclusive) in monthly 0.5 degree latitude/longitude format. Today I combined all this grid data into a global land-only drought anomaly index and show its trend over time. Result: Looks like it’s getting dryer over land, but itContinue reading “Land Drought Index Trend”
I was learning some Python over the weekend, and then afterwards decided to go for a jog at my favorite spot. As I was jogging, I thought about finding out what the temperature trend at this location was by extracting and plotting it with Python. This site seems to offer the best local 4km dataContinue reading “Warming near Coal Plants”
Is anyone curious to know what the global snowfall trend was in this era of “extreme” global warming? I was. Luckily NASA covertly provides us with all the necessary data to figure this out. I downloaded all available monthly images from 1980 to 2020 (inclusive), such as the one shown above, then I converted theContinue reading “Snow in the Era of Global Warming”
NOTE: THIS POST AND CODE IS DEPRECATED. PLEASE GO HERE FOR UPDATED VERSION. Is anyone curious to know what the global snowfall trend was in this era of “extreme global warming”? I was. Luckily NASA covertly provides us with all the necessary data to figure this out. I downloaded all available monthly images from 1980Continue reading “4 Decade Global Snowfall Trend”
I downloaded all 8-day increment Gross Primary Production data from NASA from 2001 to 2020 (inclusive) to find the 20-year trend. The Result: This is all good news. Enjoy 🙂 -Zoe The Code:
I think this dataset is very interesting. We can monitor global water level changes from 1999 to 2020 layered on top of google maps here. I naturally chose the Maldives as the starting point to see if the tiny islands nation is “doomed” as climate alarmists like to claim. Of course it isn’t. Seldom anyContinue reading “Global Water Dynamics”
The official energy budget contains a small value that some may not understand. What is does that “0.6 net absorbed” value mean? The answer is that most energy budgets mix normal (“all”) sky and clear sky conditions. To show this, I will use NOAA’s 20th Century Version 3 Reanalysis data. The code is short: TheContinue reading “Small Mystery Explained”
NASA has a data product that tracks the amount of chlorophyll in water across the globe. I downloaded all available 2003-2020 (inclusive) monthly data in 1440 by 720 pixel format to see how chlorophyll in water changes over time. This task is actually not easy because there’s a lot of missing data (black pixels). IContinue reading “Trend of Chlorophyll in Water”
Climate alarmists are worried that the sea level is rising too fast and flooding is coming soon. You can find many data images like this on the net: 3.2 mm/year. The problem is that this is for all ocean water. If flooding is a concern, then shouldn’t we ask what is happening at the coasts?Continue reading “Coastal Sealevel Rise”
In a previous post, Fortunate Global Greening, I used low resolution NASA data to determine changes to Vegetation Index. I did this because I didn’t want to spend 5 hours downloading 23 gigabytes of data for the highest resolution. I didn’t think this would matter that much, but unfortunately for me, it does. Here’s theContinue reading “Accurate Global Greening”
This is for my Aussie fans. I show how Australia’s landscape changed from 2001 to 2019 using best available satellite data. Parts of Indonesia and Papua New Guinea that should appear on the map, are changed to water. Changes: Columns are in overall percent, except the last, which shows percent change from 2001 to 2019.Continue reading “Land Change in Australia”
NASA provides global land cover classification data: Unfortunately it stops in 2011. I did a little bit more digging and found a great resource here. What I wanted to do was show surface changes over time. Here’s my result: Each year column shows coverage by percent, and last column shows the percent change from 2001Continue reading “Surface Change”
Climate alarmists claim that an increase in man-made greenhouse gas emission will cause more fires. For example … Human-induced climate change promotes the conditions on which wildfires depend, increasing their likelihood … — ScienceDaily Funk … says there is very well documented scientific evidence that climate change has been increasing the length of the fireContinue reading “Trend in Global Fires”
Update: See new information. NASA offers a data product called a Vegetation Index. This can be used to track how green the Earth is. Although many are familiar with recent global greening, I prefer to always check the source data. And so I downloaded all of their available 16-day-increment data from 2000 to 2021. Here’sContinue reading “Fortunate Global Greening”
I downloaded and analyzed 10 Gigabytes of data fully covering years 2003 to 2019 from “the only project worldwide whose prime objective is to produce global climate data records of ERB [Earth’s Radiation Budget] from instruments designed to observe the ERB” [site] [data] in order to see the effect of clouds at the surface, especiallyContinue reading “Effect of Clouds on Global Upwelling Radiation”
There, I said it. Don’t believe me? I will show you … NASA offers an online tool for measuring the effects of clouds, aerosols, and greenhouse gases. Set Output to OUTPUT_details. Note the CO2 (ppmv) setting in the bottom left. Click Compute button to express form changes. Output comes below the form, so scroll down.Continue reading “Greenhouse Gases as Coolants”
Climate “scientists” look at Earth’s geothermal heat flux, see that it’s small (~0.1 W/m²), and then conclude geothermal can’t possibly predominantly explain Earth’s surface temperature. This is plain wrong. I came up with an illustration to demonstrate my point a while ago: This is a fictional planet. I did this on purpose to accentuate myContinue reading “Geothermal Denial”
MODTRAN is a tool developed by US Air Force and Spectral Science, Inc to model absorption in the atmosphere. A free version is available from University of Chicago here. Let’s start playing with this tool. We set all atmospheric gases and other parameters to zero. The ground temperature doesn’t change – contra the opinion ofContinue reading “Climate Scientists vs Air Force”
Amateur scientist Willis Eschenbach developed a thought experiment to demonstrate how the greenhouse effect “works”: It’s been refuted many times before, but I’ll make it even simpler. The main claim is that the outer shell’s presence will force the inner core to warm up and radiate twice as much compared to no shell at all.Continue reading “The Steel Greenhouse Ruse”
With the global economic response to the COVID19 epidemic, we would expect global CO2 to be rising much less than other years, if the theory of man-made global warming is indeed true. I use data from NOAA to see what’s going on. The estimated daily global seasonal cycle and trend value for CO2 are determinedContinue reading “CO2 Versus Global COVID19 Response”
Believers of the Greenhouse Effect all use the same analogy to get you to believe in their junk science. The site Skeptical Science sets the standard in this article: So have climate scientists made an elementary mistake? Of course not! The skeptic is ignoring the fact that the Earth is being warmed by the sun,Continue reading “Do blankets warm you?”
This was derived from NCEP Reanalysis data, in the tradition of Measuring Geothermal … Enjoy 🙂 -Zoe Addendum geochg.sh: Run it: Windows users need imagemagick package from Cygwin.
I’m going to ignore the typical nonsense mainstream narrative, and do this analysis in the tradition of: Measuring Geothermal – A Revolutionary Hypothesis. I will use 41 years of NCEP Reanalysis Data. Create a new file fluxchange.sh, and paste: Run it: The results are changes for years 1979 to 2019 (inclusive). The upwelling radiation fluxContinue reading “What caused 40 years of global warming?”
Mainstream climate scientists believe in the dumbest math theory ever devised to try and explain physical reality. It is called the Greenhouse Effect. It’s so silly and unbelievable that I don’t even want to give it the honor of calling it a scientific theory, because it is nothing but ideological mathematics that has never beenContinue reading “Dumbest Math Theory Ever”
I used to be a fan of Joseph Postma before I realized he’s very stubborn and on the wrong track headed for a dead end. I hope he turns around. I highly recommend that everyone read his great series … The Fraud of the Greenhouse Effect (1, 2, 3, 4, 5, 6, 7, 8, 9,Continue reading “Deducing Geothermal”
I’m proposing a brand new hypothesis. Here it is: The so called greenhouse effect is nothing but an artifact of geothermal, flipped upside down. We can measure geothermal quite easily: Geothermal Emission = Upwelling Longwave Radiation – (Downwelling Shortwave Radiation – Upwelling Shortwave) + Latent Heat Flux + Sensible Heat Flux In the language ofContinue reading “Measuring Geothermal – A Revolutionary Hypothesis”
The standard mean sea level pressure is defined as 101.325 kPa. This is the standard used in US and International Standard Atmosphere. This value is all over the place. In reality this value was agreed upon by committee and at no time represented the true mean sea level pressure. Most certainly it does not representContinue reading “Pressure Change and Real Standard Pressure”
Today I will analyze some differences between the north and south hemisphere. I’ll be using NCEP‘s Long Term Mean Air Surface Temperature for 1979-2017, and NASA’s ISCCP Project Insolation data from 1983-2009. Sure the years don’t overlap, but we are using long term averages anyway and don’t care about the time trend. First we needContinue reading “North and South Hemisphere”
Precipitable water is a measure of how high water would stack up if all the water vapor in the atmosphere would rain down, right now! It typically ranges between 22.4 and 24.2 millimeters. All the water vapor raining down would add up to about 0.9 inches. Now a little bit of logic: the amount ofContinue reading “Precipitable Water as Temperature Proxy”
Today we will examine 40 years (1979-2018) of air temperature data and derive the average lapse rate. First we need some tools: We will be using NCEP Reanalysis 2 data. Grab it: Create a new file air.sh with: We source the code, to allow its functions to act like command-line commands we can run inContinue reading “Air Temperatures and Average Lapse Rate”
Berkeley Earth is a popular resource among climate alarmists. Today I will examine their most popular data, available here. This data is the basis of a very popular meme, the global warming color stripes. But how valid is it? Could it be a misinterpretation? First, we will need three tools: Then download & plot: LooksContinue reading “What Global Warming?”
Why Venus is hot.
You are sitting on a hot plate (Geothermal). There is a heat lamp pointing down at you (Sun). There are gases in between the lamp and the plate. Mainstream climate scientists believe the surface temperature can only be explained by the heat lamp and the gases. Yes, it “must” be the gases that make itContinue reading “Hot Plate, Heat Lamp, and Gases in Between”
There’s a [stupid] idea popular among climate scientists that there is an extra warming effect from water vapor due to the fact that CO2 and water vapor have overlapping spectral bands. Is this true?
Today I will be investigating the difference between two different types of fluxes that elude almost every climate scientist.
I figure out what percentage of Earth’s outgoing longwave radiation is absorbed by carbon dioxide.
Mainstream climate scientists believe there’s such a thing as Downwelling Longwave Radiation (DLWR) originating primarily from Greenhouse Gases. Does it actually exist? We’ll see…
NASA’s official energy budget has a subtle fraud in it. I show you where.
What is Earth’s surface emissivity? Most climate scientists don’t know. I do, and so will you 🙂
Continuing from Part 1, I further show why the mainstream Greenhouse Effect is a Fraud.
The greenhouse effect is a fraud, and I will show you why. Let’s take a typical example of a model greenhouse effect used by climate “scientists” as found in a free online book from Harvard.
I wrote a little program to help people figure out top-of-the-atmosphere insolation year-round all over the globe. You can modify it for more specific purposes. It is written mostly in awk – the best programming language for processing columnated data tables.
