Shift In Climate Normals Due To Global Warming

I was curious how much climate normals have shifted in the past few decades, so I put together some gifs looking at that.

Tool For Comparing City Climates And Finding Similar Cities

I've added a new tool that lets you find and compare cities with similar climates...

find climate dopplegangers; cities with similar climates

How Much Will Climate Change Cost?

I've looked around and have not seen a great summary of how much global warming will cost. Given that, I decided to aggregate the estimates that I could find and have summarized them here.

Is Sea Level Rise Already Increasing Flooding?

I was going to do a post on this, but a number of other groups have already done a much better job than I could do so I've summarized some of them here.

How Evenly Distributed Is Global Warming?

I tried to come up with a way to visualize how evenly distributed the warming we've seen is, and I settled on the following plot:

temperature anomaly for north america and europe

When Was The Last Time It Was Colder Than Average Where You Live?

I was curious about how evenly distributed the observed warming is, so I put together a few visualizations of it.

Why Do I Use Only Europe And The US For Historical Temperature Analyses?

I've had a number of people ask me why I focus on the US and Europe with many of the analyses, and I figured I'd explain here.

Does Global Warming Make Hurricanes Worse?

With a particularly bad hurricane season in 2017, there's been a lot of talk about climate change and hurricanes, and it's been a bit difficult to find actual science in the conversations. I figured I'd post what good information I've been able to find on the topic to answer some questions.

TLDR Climate Stories #2

These are extremely short summaries of the studies, stories, etc. related to global warming/climate change that I found most interesting in recent weeks...

The EIA Keeps Lowering Its Projections For Coal Usage In 2040

The EIA puts together what seem to be the best analyses of the world energy market, and their reports are steadily projecting less coal usage going forward...

Cool Plot Showing The Relationship Between Temperature/Global Warming And Hurricane Strength

I'm hoping they'll publish full analysis, but for now all we have is this image from a tweet:

Global Warming And Heat Index

I've seen a good bit on temperature increases from global warming and I've put together several visualizations (example), but I haven't seen any clear heat index projections. I went ahead and put some together for the US.

How Much Does Extreme Weather Currently Cost?

I was curious how much extreme weather currently costs so I did a bit of googling and made a visualization of the best results I could find.

TLDR Climate Stories #1

These are extremely short summaries of the studies, stories, etc. related to global warming/climate change that I found most interesting in recent weeks...

Visualizing A Heat Wave - 2011 US

I took a crack at visualizing a heat wave because I thought that might look cool. I chose the 2011 heat wave in the central and southern part of the US. I picked this one because I live in Austin, TX and this heat wave is still somewhat famous here.

New Tool For Comparing City Climates

I've added a new tool that lets you compare city climates and it is here.

Make A Simple Climate Model From Scratch

I wanted to make a simple climate model from scratch, so I took some of the data that's available and created one. I've written up the process in detail here for anyone who wants to do something similar and have created a simple tool using this that you can play with here.

6 Ways Global Warming Is Already Affecting The World That You Might Have Missed

I submitted this as a pitch to and it was rejected for being too obvious to everyone, so I figured I'd post it here since I'd already written it.

We often hear about how bad global warming will be, but that’s not really a big deal because that’s a problem for future humans to deal with. Wouldn’t it suck though if previous generations thought that also and we’re their future humans. Well…there’s bad news…

Tutorial For Working With NetCDF Climate Data In Python

There's a massive amount of climate data out there, and it's not always easy to find and understand. I figured I'd make a quick tutorial for anyone who wants to start working with it. This also serves as a tutorial for reading data from netcdf files in Python.

New Tool For Seeing If Your Summers Have Gotten Hotter

I put up a recent post analyzing if it's noticeably hotter yet, and in talking with a co-worker I realized a tool might help visualize that in a way that's more intuitive for people so I wrote one.

Good Books About Climate Change

I've read a good bit about climate change over the years and a question on the other day made me think about what my favorites are. I figured it was worth making a list with my reviews of them so here it is.

Has It Already Gotten Hotter?

A reasonable question to ask is, "We've been pumping greenhouse gases into the atmosphere for a while it getting noticeably hotter yet?" I've attempted to answer that with a few different metrics.

Search Engine That Plants Trees

This might be a scam...I'm not actually sure, but there's a search engine called Ecosia ( that claims to use the ad revenue they earn from users to plant trees. I have been using the site for a little over a month now and haven't run into any issues with it. Full disclosure though...I did use bing before that because they pay you to use them, so my standards for a search engine might not be the same as everyone else's.

Still...check it out if you're interested.

How Much Energy Do We Use?

It's difficult for me to really understand how much energy we use. Can we replace gasoline with leftover oil from restaurants? Can we replace coal with solar? I decided to convert our usage into things that are easier for me to wrap my head around.

Compare City Climates

I've added a new tool that lets you compare the climates of two cities.

How Do I Know If An Article I See Is Accurate?

A lot of articles are written about climate change and it might be difficult to know what is accurate, what is media hype, and what is actual lies meant to push an agenda. There's a cool site that actually has scientists evaluate the quality of articles on climate change that might help with that:

They rate things on a scale of -2 (very low credibility) to +2 (very high credibility) and give explanations of their review.

If you know of any other sites like this, please let me know.

How Expensive Are Greenhouse Gases?

Emissions will change our climate which will affect our GDP. How big of an impact might this be?

When Might We Be Able To Grow Oranges In Atlanta?

As temperatures rise, the areas in which specific crops will grow will shift. When will they shift enough for us to be able to grow oranges in Atlanta?

Atmospheric CO2 API

I've added a new tool that you can use that returns atmospheric CO2.

When Might We Stop Seeing Snow At Christmas?

As the Earth warms, winters will start getting warmer. Eventually, we should stop expecting snow at Christmas in some areas that currently get it. When might that be?

Carbon Budget Tool

I've added a new carbon clock tool that you can use in your website to track when we'll overrun our carbon budget.

Who Is Leading The Move To Clean Energy? (Part 1)

Clean energy is already a massive industry and will continue to grow going forward as it becomes cheaper and as the world is forced to move away from fossil fuels. Who is emerging as a leader in this industry and what energy types are getting the most investment?
