*Weaponising the climate crisis: How extremists and politicians are 
polarising the debate*/
/By Rosie Frost
Published on 20/08/2023

As the UK looks at rolling back green commitments, there are concerns 
that climate issues are feeding into cultural confrontation and identity 
politics.

Climate change has once again become a hot topic in the UK but for all 
the wrong reasons...
- -
Jennie King, an expert in the evolving trends of climate mis and 
disinformation, says that many aren’t entirely sure what they mean when 
they use the term.

“You now have a space where the traditional climate deniers or delayers 
are merging with a much broader and largely decentralised universe of 
extremists and conspiracy movements,” the head of Climate Research and 
Policy at the Institute for Strategic Dialogue (ISD) explains...
- -
This leaves the space open to “professional disinformation actors and 
outrage merchants”...

“What's really coming to the fore in conversation at the moment is how 
easy it is to exploit the gap between general public approval and 
recognition for the necessity of climate action versus actually being 
able to propose and implement an ambitious policy platform,” King adds.
- -
Ultimately what is lost in this polarisation is the ability to have 
sober and candid conversations about the net zero transition. Essential 
debates between citizens and elected officials get pulled into this 
highly divisive space and everyone loses out.

“[It] has nothing to do with the substance of policy and is all to do 
with who should or should not be involved in the conversation,” King explain

Aug 20, 2023
Our thanks to Just Collapse for posting this CNN footage.

Professor Eliot Jacobson is not a climate scientist - he is however a 
very concerned global citizen who has dived deep into the current, dire, 
human-caused collapse of Earth Systems. His very regular postings on 
Twitter and his own blog have helped thousands of people around the 
world understand just how significant the events of this year, this 
season and today are as indicators of an acceleration of human-caused 
collapse.

In this CNN clip professor Jacobson articulates three different stunning 
indicators of just how quickly we are causing "The Sixth Mass Extinction."

Many thanks to professor Jacobson, to CNN, and our friends at Just 
Collapse, for producing this clip.

We gladly include this clip in our most recent online course, Collateral 
Beauty.

This course, and all of our offerings here in Living Resilience and The 
Poetry of Predicament, are intended to support and resource the global 
Collapse-Aware and Collapse-Acceptant communities.

/[ Serious studies of the longer term effects of wildfires -- BBC ]/
*Extreme wildfires are increasing due to rising emissions, but they also 
disrupt the climate in return. Weighing up the overall impact, however, 
is tricker than it seems.*

*Albedo and evaporation*

Wildfires can also influence climate back on the ground.

One mechanism involves changes to a landscapes' albedo, or ability to 
reflect light. In the aftermath of a fire, charred surfaces can reduce 
albedo, leading to an increase in surface warming. Conversely, a reduced 
forest canopy can raise albedo by exposing more reflective entities such 
as grass or snow, leading to a cooling effect.

Another process involves the evaporation of water. Thriving plants 
release water from their leaves in a process known transpiration, and 
water also evaporates directly from the soil and canopies. The 
surrounding air is cooled as a result. But when wildfires suppress this, 
warming increases.

A 2019 study which investigated the interplay of these factors found 
that the average surface temperature can warm for at least five years 
after flames are extinguished. Reduced transpiration was found to be the 
main cause of this, says Zhihua Liu, an ecology researcher at the 
University of Montana and lead author of the study...

*Biophysical feedback of global forest fires on surface temperature*
Zhihua Liu, Ashley P. Ballantyne & L. Annie Cooper

    *Abstract*
    The biophysical feedbacks of forest fire on Earth’s surface
    radiative budget remain uncertain at the global scale. Using
    satellite observations, we show that fire-induced forest loss
    accounts for about 15% of global forest loss, mostly in northern
    high latitudes. Forest fire increases surface temperature by 0.15 K
    (0.12 to 0.19 K) one year following fire in burned area globally. In
    high-latitudes, the initial positive climate-fire feedback was
    mainly attributed to reduced evapotranspiration and sustained for
    approximately 5 years. Over longer-term (> 5 years), increases in
    albedo dominated the surface radiative budget resulting in a net
    cooling effect. In tropical regions, fire had a long-term weaker
    warming effect mainly due to reduced evaporative cooling. Globally,
    biophysical feedbacks of fire-induced surface warming one year after
    fire are equivalent to 62% of warming due to annual fire-related CO2
    emissions. Our results suggest that changes in the severity and/or
    frequency of fire disturbance may have strong impacts on Earth’s
    surface radiative budget and climate, especially at high latitudes...

Our results also indicated that fire-induced forest loss may alter 
Earth’s surface radiative budget through different biophysical 
processes, despite the limited satellite observations. Specifically, 
short-term fire-induced changes in albedo exhibited distinct seasonal 
patterns, which appeared to cancel each other out between snow and 
snow-free seasons (Supplementary Figs. 8-9 and Supplementary Table 1), 
therefore leaving decreased evapotranspiration during the growing season 
as the dominant control on the surface radiative budget and thus 
temperature response in early post-fire successional stages...

/*August 21,  2007*/
August 21, 2007: U.S. District Judge Sandra Brown Armstrong rules that 
the George W. Bush administration violated the 1990 Global Change 
Research Act (signed into law, ironically enough, by Bush's father) by 
not producing a legally required climate assessment report. The report 
would finally be released in May 2008.
