Extreme Heat Increased 22,100 Percent in Last 40 Years James Hansen has a new post out to his big list where he shows heat extremes across Northern Hemisphere land areas have increased a mind bending 22,000 percent. Breaking down Hansen’s work, in the classic 3-standard deviation bell curve colored red, white, blue and burnt sienna with…
Microsoft on climate: The game changer Historic climate pollution emissions almost everyone missed. By Bruce Melton First published on the RagBlog.org, February 3, 2020 Microsoft going net zero by 2030 is a tremendously insightful action, but what’s truly groundbreaking and ever so much more important today, 30 years after we began trying to solve the…
State of the Climate Report 2018, American Meteorological Society Unsurprisingly, we have roundly exceeded climate norms in our old climate. Records continue to be broken and climate statistics broadly show we are exceeding or near the leading edge of warming in recent years, as would be expected from a climate that continues to warm, that…
NASA: The Last 5 Years Hottest on Record? Yes, the last five years have been the hottest five years recorded since 1880. This is a big deal. But what we hear in the media portends bigger things. One of the biggest is the meaning of the yearly average temperature and its relationship to our old…
Feedbacks kick in: 2017 is second warmest without El Niño influence by Bruce Melton First published on The Rag Blog, February 1, 2018 NOAA, the UK Met, and World Meteorological Organization (WMO) have all stated that 2017 was third warmest. But these three organizations use data that only averages temperature in the Arctic out to…
We have all heard it before: “What’s so bad about a little warming?” Several things are at play here. First, it’s winter. It’s far colder in winter than the warming we have experienced. So when it’s winter it’s cold, relative to when it’s not winter. But a little warming can’t be that bad, right?Our global…
The greatest climate dude of all time has done it again. James Hansen, 32 year director of the U.S. national climate modeling agency, the NASA Goddard institute for Space Studies, published a new fundamental piece of climate work last month. He looks at the additional negative emission on top of Paris reductions that are needed…
It’s all around us but masked by “noise” in the media; enabled by fairness in journalism, driven by myth that has been propagated by experiences that we as a society have never before experienced. When Unprecedented drought in California was replaced by unprecedented flooding, the paper says: “The media, resource management entities, and the scientific…
It’s a widely held misconception that implementation of Paris Climate commitments would tame the climate beast. This has no more been the case in the past than it is today. Our culture of climate policy has always relied on overshoot, or additional increase in temperature as we implement greenhouse gas regulations and reduce the amount…
One of the general quandaries about current climate change impacts and those with our future climate has been: “how do we end up with drying when precipitation increases with warming as we already see happening and is further projected in the future?” This research from Princeton, University of Southampton and the US Geological Survey does…
In 1834 and 1850, two European scientists (Clausius and Clapeyron) developed scientific principles that told us that warmer air holds more water. In the 1960s and 70s the computer models that first simulated our climate showed that more atmospheric CO2 would increase Earth’s temperature, relative humidity, and total precipitation because of the Clausius–Clapeyron principles. In the…
Super Nino may have caused the temperature peak, but the chaos is weather too. The big question is, “how much will it cool off next year?” It may not be much. The way the extremes are increasing (and have you seen the recent jump in sea level rise) it is becoming obvious that we have…
Two degrees C was first suggested as an upper limit to where we should allow our climate to warm by Nordhaus (Yale) in the American Economic Review in 1977 with the justification that this amount of change would exceed the temperature envelope where our mature civilization has developed. Nordhaus cites Sellers 1974 and NCAR 1974…
The driver of our climate system has changed in the last two decades from one that is controlled by annual emissions, to one that is controlled by already emitted CO2. This means that previous strategies to control annual emissions are no longer meaningful and we must now turn our attention to the already emitted climate…
Pop Quiz: How Much of the Warming is Natural? Or more precisely; “How much warming has been caused by mankind’s emissions of fossil greenhouse gases?” None About half Most of it All of it None of the above This is a piece of science I have been struggling with since I discovered the Milankovitch cycles…
First published on Truthout: October 4, 2015. Over 20 years after a global consensus of earth scientists at the Rio Earth Summit first suggested we control carbon dioxide emissions to prevent dangerous climate change, the United States has finally acted. This is excellent news for 20 years ago but today, Kyoto V2 (the EPA’s Clean…
Final Sentence “Indeed, based on our new analysis, the IPCC’s (1) statement of two years ago – that the global surface temperature “has shown a much smaller increasing linear trend over the past 15 years than over the past 30 to 60 years” – is no longer valid.” The abstract: Much study has been devoted…
Once again we ask “why has the apparent global temperature lagged behind accelerating CO2 emissions”? The reasons are numerous and logical, yet the media and prominent climate change deniers continue to ignore their significance, if they even understand they exist at all. Cherry picking the beginning point of the so-called hiatus by starting it during…
Work from the Institute for Atmospheric and Climate Science, Zurich, Switzerland has found that about 18% of moderate daily precipitation extremes and about 75% of moderate daily hot extremes, that are currently occurring over land, are attributable to warming. An ensemble of the latest models was used to try and average the individual modeling from…
First published on Truthout.org April 24, 2015. “The best estimate of the human-induced contribution to warming is similar to the observed warming [from 1951 through 2010].” IPCC 2013, Summary for Policy Makers.(1) This statement differs radically from the almost ubiquitous understanding that part of global warming has been caused by humanity and part is natural. In…
