How Climate Change is a Security Threat Multiplier and What Can Be Done?

Climate change is adversely affecting human security in many different ways and the impacts of it are growing rapidly.  As a result, security experts often indicate that climate change is a threat multiplier that can lead to serious problems with cascading effects such as famine, conflict, large-scale war, the collapse of governments, and/or forced mass migration. Given below is one example of human security issue that is being amplified by climate change, why this and other types security issues are growing rapidly and what can be done on a large-scale address one of main causes of these growing security issues:
.
1) Given below is an article about one example of what is happening in Afghanistan right now and is being amplified by climate change:
She was sold to a stranger so her family could eat as Afghanistan crumbles By Anna Coren, Jessie Yeung and Abdul Basir Bina, CNN, November 1, 2021
2) Given below are some articles that outline just how big the food security problem is in Afghanistan at this time:
Herders forced to sell livestock, farmers flee villages and parents marry daughters off at even younger age amid the crisis.
b) Afghanistan hurtling towards collapse, Sweden and Pakistan say By Alexander Cornwell, October 24, 2021
Urgent need for a huge amount of humanitarian aid, World Food Programme director says
World Food Programme (WFP) executive director David Beasley told Reuters that 22.8 million people — more than half of Afghanistan’s 39 million population — were facing acute food insecurity and “marching to starvation” compared to 14 million just two months ago.
.
3) An article about some efforts to provide aid to help deal with the food security problem:
Italian prime minister Mario Draghi hosted an ‘extraordinary leaders’ summit’ to discuss the looming humanitarian disaster in Afghanistan
.
4) An article highlighting how the food scarcity and security problems in Afghanistan are part of a growing trend that is occurring in other parts of the world:
Eleven countries in Asia, Latin America and the Middle East are especially at risk from instability driven by climate change, says a U.S. intelligence report.
.
5) Concise summary from the script of ClimateSAN’s presentation video: Opportunities For Large-Scale Carbon Emissions Mitigation & Need for Action
When the media reports on the impacts of climate change, they are often referring to forest fires, flooding and/or violent storms.  From my experience in Afghanistan and Africa, I feel that these impacts are relatively minor compared to the impacts on human security that many security experts warn about.  These security experts often indicate that climate change is a threat multiplier that can lead to serious problems with cascading effects such as famine, conflict, large-scale war, collapse of governments, and/or forced mass migration.  One recent estimate of expected mass migration was done by the Institute for Economics and Peace (IEP), which estimated that the climate crisis could displace 1.2 billion people by 2050. (Reference: CNN: Climate crisis could displace 1.2 billion people by 2050, report warns By Jessie Yeung, CNN, September 10, 2020.  This report is called the Ecological Threat Register (ETR) and was produced by the Institute for Economics and Peace (IEP).)

7) As shown in the graphs on this page, measured atmospheric CO2 levels are continuing to rise: Current Warming Trend.   There are several factors contributing to this rising CO2 level but the main reason for this rise is that the total overall global energy demand appears to be increasing faster than the renewable energy generation growth rate.
8) The current warming trend keeps rising and UNEP analysis suggests the world is on course to warm around 2.7C. See:

b) Video: See what three degrees of global warming looks like, The Economist, Oct 30, 2021
c) BBC: Climate change: UN emissions gap report a ‘thundering wake-up call’ By Matt McGrath, Environment correspondent

9)  Unless the oil, gas, and coal industries are engaged to help reduce carbon emissions on a substantial scale, adequate action needed to avoid catastrophic levels of climate change will not likely occur.
.
10) To help engage the oil, gas, and coal industries to reduce carbon emissions on an adequate scale, security experts can help “bridge the gap between believers and doubters” on the need for large-scale action.  Prof. Michael Klare gave a keynote speech about this topic at this conference: Impacts of Climate Change on Human Security: What Can Be Done?
.
11) Currently, there are substantially subsidies for the oil, gas and coal industries.  For example,
The International Monetary Fund (IMF) has determined that the [global] production and burning of coal, oil and gas was subsidized by $5.9 trillion in 2020 ($11 million every minute )
.
12) Although there is political pressure to reduce these subsidies, the oil, gas and coal industries will likely use their resources and influence maintain these subsidies as much as possible.  To enable a faster transition, these industries can be engaged to support the redirection of fossil fuel subsidies towards energy generation that benefits these industries but reduces carbon emissions instead of increasing them.  Fortunately, this is now possible due to rapid advances in technologies in several areas.
