Challenge to Michel

Reader “Michel” expressed his opinion that when it comes to climate science, “… this mysterious beast you call a denialist. They don’t exist, at least not in the way you mean.” A bit later, he asked me “… if you…

Cycle Change: Arctic Sea Ice Edition

After my last post, a reader asked: What’s most noticeable about this is the massive change in variability since 2007. Could you do some analysis of that? Sure. I’ve done this before, but it bears repeating because it is a…

Arctic Sea Ice

Since 1979 we’ve been measuring the extent and area of sea ice in the Arctic using satellites. This is what we’ve found (data from NSIDC, the National Snow and Ice Data Center): Obviously there’s a strong seasonal cycle, with more…

Crash Override

I’ve recently read a book which opened my eyes, and impressed me with a level of enlightenment and self-awareness I haven’t seen since I watched the film “Gandhi” (I’ve watched it at least 20 times). The book is Crash Override…

Destroying the Country

When Michael Morell warned about existential threats to America — things that could destroy the country — he listed three. One of them, he described thus: “And then the third, and some people may laugh at this but it’s absolutely…

What is sea level up to lately?

Since 1993 we’ve been monitoring sea level with satellites. The overall rise is obvious (it was obvious even before 1993), and we now know that the rate of rise is faster than it has been in a very very long…

Hurricane Harvey Hurts Texas

There’s a lot to be said about the relationship between the damage from Hurricane Harvey and climate change. But that can wait. People are hurting. People are afraid. People have died. So I’m urging readers to donate — everything helps,…

Ich Bin Schwarz

On June 26, 1963, President Kennedy spoke in West Berlin to an audience of nearly half a million, and showed his support for their hopes to preserve freedom in spite of being surrounded by the communist empire, by declaring “Ich…

Understanding Sea Level Rise

Sea level rise is complicated. But some people think its future course is oh so simple, and the recent visit by a certain Mr. Wakefield showed just how determined he is to stick with what I call the “simpleton’s view.”…

A Few Other Stations

Mr. Wakefield doesn’t seem to like the tide gauge data from Boston, since it so easily shows how wrong he was about “NO acceleration.” He wants me to “do a few other stations, like in Australia and Brest, France.” Let’s…

Sea Level Rise has Accelerated

There seems to be some interest in global sea level as estimated by tide gauges. In particular, we have recently been directed to a graph of the data from Church & White, which is the most reputable of the available…

Boston Sea Level

How one plots the data can have a big impact on whether or not one can “see” acceleration or deceleration of sea level in tide gauge data. Here, for instance, is a plot of sea level at Boston (data from…

Does Willis Eschenbach have Any Honor?

Let’s find out. He wrote a new post at WUWT claiming this about James Hansen’s 1988 prediction of the course of temperature change over the following 30 years: Back then, he said the globe would warm up by two to…

Sea Level Rise is Accelerating

Willis gets it right? Not. Willis Eschenbach has a post at WUWT claiming to show that sea level rise is not accelerating. What he actually demonstrates is that he doesn’t know how to tell. His method is to fit a…

Scott Pruitt and the Whiny Crybaby Losers

Scott Pruitt wants to replace science with a 3-ring circus Scott Pruitt, new head of the Environmental Protection Agency (EPA), wants a “red team/blue team debate” about global warming. That’s where two sides argue different opinions on some topic, and…

Climate Trend Change? Do it Right

Because scientists, you’re doing it wrong. There’s a mistake you keep making, as many times as I point it out, even in the peer-reviewed literature, you keep doin’ it wrong. If you’re a scientist, then maybe yes this means you.…

Still Here

I thought I should let regular readers know that I’m still here, still alive, and that posts will be back before very long. It’s been crazy lately, and I’m involved in two new projects. One is private, the other is…

Hammering the Trend

I tend to hammer away at the concept of trend. Like many, I’m especially interested in whether, and if so when, trends have changed. Recent research from Oliva et al. is all about trend change in temperature on the Antarctic…

Fascinating FaceBook post from France. Dear Mr Trump, thank you for your concern. A man has indeed attacked a soldier with two machetes this morning in Paris. It wasn’t in the Louvre Museum, it was in the Carrousel du Louvre,…

Sea Ice Seasonal Cycle

Several readers mentioned that the plot of sea ice anomaly in the Arctic shown in the last post has much greater fluctuation after about 2007. Anomaly values are the difference between a given time’s extent, and the average for that…

Climate Denial about Sea Ice

When it comes to Arctic sea ice, climate deniers have a hard time explaining why it has declined so far so fast. It’s one of the most telling signs of global warming, a stark message from Earth to deniers: it’s…
