Global Hurricane Hours

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”

Atlantic Hurricanes Trend

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”

Land Drought Index 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”

Snow in the Era of Global Warming

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”

4 Decade Global Snowfall Trend

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”

Trend of Chlorophyll in Water

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”

Accurate Global Greening

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”

Land Change in Australia

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”

Trend in Global Fires

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”

Fortunate Global Greening

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”

Effect of Clouds on Global Upwelling Radiation

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”

Greenhouse Gases as Coolants

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”

Geothermal Denial

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”

Climate Scientists vs Air Force

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”

The Steel Greenhouse Ruse

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”

CO2 Versus Global COVID19 Response

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”

What caused 40 years of global warming?

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, 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?”

Dumbest Math Theory Ever

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”

Measuring Geothermal – A Revolutionary Hypothesis

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”

Pressure Change and Real Standard Pressure

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”

North and South Hemisphere

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 as Temperature Proxy

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”

Air Temperatures and Average Lapse Rate

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 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”

What Global Warming?

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?”

Hot Plate, Heat Lamp, and Gases in Between

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”
