Katrina, Fire, Heat, Melt

Just a few pointers to some of today’s interesting climate stories. First, this is the tenth anniversary of Hurricane Katrina. After ten years, the costs of that hurricane are still being paid. See this overview. Also, astonishingly, or perhaps totally expectedly, one third of Louisiana blame a Democratic Senator from the Midwest for the lousy…

Scientific Consensus On Climate Change

A new paper examines what is behind the ~2% of climate change related peer reviewed research that run contrary to widely accepted scientific consensus on climate change to see why those papers are wrong. There is a scientific consensus that increasing greenhouse gas concentration in the atmosphere causes surface warming, and that CO2 is a…

We need to act urgently to reduce the amount of greenhouse gas pollution we humans create in order to slow down and eventually stop climate change. In the mean time we see case after case of something happening that seems unusual and that seems linked to global warming. We need not wait for the jury…

Climate Models Accurately Predict Warming Climate models employ piles of data and sophisticated computational techniques to predict what will happen in the future. Sometimes they predict what happened in the past as well. That is important to test the models (because we might know what happened in the past), or to fill in the blanks…

There are two new scientific research papers looking at variation over the last century or so in global warming. One paper looks at the march of annual estimates of global surface temperature (air over the land plus sea surface, not ocean), and applies a well established statistical technique to ask the question: Was there a…

Men and women are different, on average, in a number of ways. It all probably starts with who has the physiology to have babies and who doesn’t, and the differences spread out from there, affecting both the body and the mind. Decades of research show us that many of the body differences (but not all)…

What is not new Ultimately sea levels will rise several feet, given the present levels of CO2 in the atmosphere. We already knew this by examining paleo data, and finding periods in the past with similar surface temperatures and/or similar atmospheric CO2 levels as today. I put a graphic from a paper by Gavin Foster…

June 2015 was warm

Every month NASA GISS comes out with the new data for the prior month’s global surface temperature, and I generally grab that data set and make a graph or two. In a way this is a futile effort because the actual global surface temperature month by month is not as important as the long term…

A new paper has just been published. This paper is going to cause an uproar in the science denialist community. Mud will be thrown. Tin hats will be donned. Somebody better check the oil pressure. Conspiracies everywhere I see conspiracies everywhere. It’s true. Look at any internet site that talks about health, disease, diet, or…

Focusing on Earth, but also a few tidbits on wind, fire, and ice, some current news and observations about global warming. Earth As humans release greenhouse gas pollutants (mainly CO2) into the atmosphere, the surface of the Earth, and the top 2000 meters of the ocean, heat up. But some of the CO2 is absorbed…
