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:

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”

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?”

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?

What is Earth’s surface emissivity? Most climate scientists don’t know. I do, and so will you 🙂

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.
