The Sequoia Burn Giant Sequoias: A Climate Tipping Point by Bruce Melton PE Follow MeltOn in the field on Instagram See the abridged version on Truthout.org: August 9, 2022. Summary: Up to 13,000 mature sequoias were killed by wildfire between 2015 and 2021, with a total known population of only about 75,500 mature trees. Sequoias…

The expedition was 16,199 miles, 46 days, 42 different camps, 2 motels – Texas, New Mexico, Arizona, California, Oregon, Washington, British Columbia,…
What’s the Big Deal With Climate Change? We all understand climate change is trouble. Even a really significant percentage of oil and gas professionals understand. Of a recent poll (2014) of 474 oil and gas industry insiders, 85 percent believed global warming was happening, 58 percent were either very sure or extremely sure, and 57 percent…
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…
Slowly and insidiously, or abruptly and finitely. Forests of all kinds are succumbing to climate change. Mountain forests, city forests, forests in the southeast and the far north. Pine, spruce, fir, oak, maple. Nontraditional forests too; the palms of LA, succulents in the desert. Yes, deserts are at risk too. Deserts as ecosystems are fragile…
The list of Amazonian drought records has grown to Amazonian proportions. Three 100-year plus droughts in a decade have taken their toll. Along with continual man-created ecological compromise, climate warming, and forest mortality from drought a very strong El Nino has grown into their strongest drought ever recorded since record keeping began in 1900. The…
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…
A recent article in Atlantic implies climate change to be wrongly viewed as something we don’t yet know much about. This article “American Trees Are Moving West, and No One Knows Why”, is half correct. The authors in the study reported upon reveal the reasons why trees are shifting west (as well as north), and…
President Trump it seems, has given us permission to backslide with our thinking about climate change. Until we have rule or law that tells us we must do something about climate pollution, “those that would rather it not be real” have won. This allows the debate to rage encouraging doubt. The Clean Power Plan and…
We can have a healthy climate — a climate with zero warming — in our lifetimes. The message for the last 20 years has been that we have to reduce emissions drastically to prevent dangerous climate change of more than 2 degrees C (3.6 F). This strategy would have likely worked when it was…
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…
This is the original long version with much more detail and all of the destinations and forest health descriptions along the 6,000 mile route. The abbreviated 2,000 word version was published on Truthout on February 16, 2016 is here. We were awash for 19 days in a tumultuous sea of mountains and forests, drifting a course through the heart…
Climate change projected by the IPCC 2013 report under the business as usual scenario (RCP8.5) projects climate change in the next 100 years to be as big as the Paleocene/Eocene Thermal Maximum extinction event 56 million years ago. Changes today however are happening 100 times faster than the PETM. The PETM was likely a methane…
When will we completely leave our old climate? When will our new climate be 100 percent different than our old? When will the normal temperature in the our new climate be warmer than anything in our old climate? It’s called Climate Departure and it is coming soon to a planet near you. On the path…
Five degrees of change—a half zone. Not average temperature; this is based on the average last freeze. I gave a presentation to the Austin Organic Garden Society last month and I remembered USDA had recently come out with new hardiness zone maps. The USDA changes in 2012 are not so much different than the 2006…
How do we curb emissions with the way our society has evolved? Really. I mean serious curbing; enough to prevent dangerous climate change? When considering the answer, dangerous climate change must be clearly defined. So, what exactly is dangerous climate change? Read More — First published on the Rag Blog
(170 pages) Ecological thresholds occur when external factors, positive feedbacks, or nonlinear instabilities in a system cause changes to propagate in a domino-like fashion that is potentially irreversible. Atmospheric carbon dioxide has reached levels unprecedented in possibly the last 24 million years. CO2 concentrations have risen by 34%, mostly in the last several decades. Global…
