APOLOGIES FOR FALSE ALARM
Many contributors received erroneous emails recently saying their articles had been deleted. This is not the case.
The problem originated in an effort to clone the site for other purposes. We understand how this happened, and it actually had very little to do with the P3 site itself. [more]
It may well be interesting to study scientists as a group, but it can tell you very little (if anything) about science itself. If you want to understand the systems being studied, you study those systems, you don’t study those who are doing the research. here
If you don’t know what the poster session is like, you don’t know what AGU is like. I’m here to help. [more]
The key to advancing your scientific conclusion is to be your own harshest critic. As a beginner, you will find yourself wrong far more often than right. But you will be wrong in ever more interesting ways. [more]
Science has a problem. But science doesn’t have a strategy. [more]
There’s new modeling evidence that suggests the world is going to warm more slowly than the global climate models have heretofore suggested.

Today I Learned, on good authority, that it remains impossible to exclude 3 meters of sea level rise within a single human lifetime from West Antarctica alone.
If it is possible, it’s further impossible to exclude it in the lifetimes of people now living.
The time scales of the collapse of calving ice sheets depend sensitively on temperature and on the height of the cliff. [more]
Stoat argues that the fundamental question Scott Adams poses, How the heck can you – a non-expert – judge who is right? – remains a good one; but that his answer is worthless. [more]
John Nielsen-Gammon: “science doesn’t work by making predictions about future events, for the most part; it makes predictions about observable aspects of the world, things detectable in the present. The amount of trust scientists place in climate models, for example, depends on their ability to simulate relevant aspects of the past and present world. The amount of trust the public places in climate science should depend on the weight of evidence in the past and present world, which is enormous.” [more]
It is not widely understood that carbon dioxide persists in the atmosphere for centuries, so our future will depend on the total amount we humans put into it over the next several decades. This is the paramount fact that separates climate change from all other environmental problems.

Today is a red letter date in the history of the world, as the Paris Accord comes into effect. Or maybe it isn’t. The political and activist side of the climate community is portraying the accord as a breakthrough and the beginning of a turnaround in the world’s self-destructive path. But many of us who are scientific and technical professionals have a far less sanguine view of the whole thing. [more]
So, why is everyone so ecstatic about this latest xkcd cartoon?
It’s not as if it’s telling us much we didn’t know. [more]
Results suggest that even the observed short-term temperature sensitivity from the Arctic will have little impact on the global atmospheric methane budget.
