On The New WMO "Annual to Decadal" Climate Report
The World Meteorological Organization ("WMO") has just put out their latest "Global Annual to Decadal Climate Update".

Correction Delayed is Correction Denied: Botched Coverage of "Geoengineering" Report by the New York Times
The letter below was submitted to the New York Times on 3/26 in response to their 3/25 article on the recent National Academy of Sciences "Solar Geoengineering" report (I commented on the report here last week). The Times has evidently declined to run the letter, so I am publishing it myself here.
My Comments on New National Academy Report on Geoengineering
The U.S. National Academy of Sciences has published a new report ("Reflecting Sunlight") on the topic of Geoengineering (that is, the deliberate manipulation of the global Earth environment in an effort to offset the effects of human carbon pollution-caused climate change).
The Rise and Fall of the "Atlantic Multidecadal Oscillation"
Two decades ago, in an interview with science journalist Richard Kerr for the journal Science, I coined the term the "Atlantic Multidecadal Oscillation" (the "AMO" for short) to describe an internal oscillation in the climate system resulting from interactions between North Atlantic ocean currents and wind patterns. These interactions were thought to lead to alternating decades-long intervals of warming and cooling centered in the extratropical North Atlantic that play out on 40-60 year timescales (hence the name).
The Salem News Promotes Deadly Disinformation
The Salem News is small town newspaper based in Salem Ohio. It appears to have far right-of-center editorial policies.
Comments on New "World Weather Attribution" Analysis of Australian Bushfires
As some readers will know, I happen to have been on sabbatical in Australia these last past months. I came there to study the impact of climate change on extreme summer weather events with a specific focus on Australia. Only to arrive in mid December just in time to encounter the most profound example on record.
The STORY about the ‘business as usual’ story is misleading
A new commentary in the journal Nature by Zeke Hausfather and Glen Peters is making the rounds today.

Oral Opening Statement from Michael Mann Testimony to U.S. House Oversight Committee Hearing on Climate Change & Natural Disasters (June 25, 2019)
The video for the full subcommittee hearing is available here (my opening statement starts at 23:00).
My Interview with Al Franken
So, this happened.
I did an interview with Al Franken for his new podcast a few weeks ago. It airs tomorrow.
On The Importance of Diversity in Climate Communication
In light of recent social media posts and conversations I've had with colleagues, I want to take this opportunity to make a statement about the importance of lifting the voices of women, people of color, and other voices that have been marginalized in the world of science communication, including the discourse over climate change.
Vice: A Commentary on the Politics of Climate Denial
I was recently invited to a screening of the new film Vice,
Climate Change and Extreme Summer Weather Events – The Future is still in Our Hands
Summer 2018 saw an unprecedented spate of extreme weather events, from the floods in Japan, to the record heat waves across North America, Europe and Asia, to wildfires that threatened Greece and even parts of the Arctic. The heat and drought in the western U.S. culminated in the worst California wildfire on record. This is the face of climate change, I commented at the time.
On Tropical Atlantic Warmth and Hurricanes
A new study just out in Science attributes the unusually active 2017 Atlantic hurricane season to tropical Atlantic warming. Furthermore, it attributes that warmth to human-caused climate change (a combination of increasing greenhouse gas concentrations and sulphate "aerosols" from industrial pollution).
Hurricane Florence - A Climate Change Triple Threat
Here's the "Director's Cut" of my recent op-ed in The Guardian (includes nearly three extra paragraphs toward the end)

Hurricane Florence - A Climate Change Triple Threat
We Need New Leadership
During the past year, I have published letters and op-eds in the New York Times, the Washington Post and the Wall Street Journal (among m
A Return to the Madhouse
Two years ago, in the home stretch of our last presidential election, Washington Post cartoonist Tom Toles and I published a book about climate change denial (“The Madhouse Effect: How Climate Change Denial Is Threatening Our Planet, Destroying Our Politics, and Driving Us Crazy”). Denialism was still a major problem, we argued.
Our Response to the Latest Climate Change-Denying Wall Street Journal Op-Ed
Fixing the headline would be simple (just remove “but Not”), but the op-ed itself is irreparable, constituting little more than a litany of denialist talking points. No, ice is not accumulating on Earth—it is melting.
Climate Change Denial in the Age of Trump
With a climate change denier in the White House, climate denialism has reached a new low point in America. Indeed, my co-author Tom Toles and I have devoted a whole new chapter to the matter ("Return to the Madhouse: Climate Change Denial in the Age of Trump") in the new paperback edition of our book The Madhouse Effect (now available for pre-order).
A Sensitive Topic
There is a quantity known as the "Equilibrium Climate Sensitivity" or "ECS" that serves as a traditional measure of the warming effect of greenhouse gases. The ECS characterizes the total warming we would expect from a doubling of the concentration of greenhouse gases (e.g. from the pre-industrial level of 280 parts per million to the 560 ppm level that would be expected by the middle of this century if we continue with the unabated burning of fossil fuels) once the climate system fully adjusts to this increase.
