Lethal Humidity Global Council's letter to world leaders

DUBAI, UAE, Dec. 5, 2023 /PRNewswire/ -- Fortescue Executive Chairman and Founder, Dr Andrew Forrest AO, has joined leading scientists from around the world in signing an open letter to world leaders attending COP28 detailing lethal humidity's growing threat to humanity.  

The letter from members of the Lethal Humidity Global Council includes the signatures of scientists from India, North America, Australia, the UK, Singapore and Belgium. 

It calls on world leaders to "move beyond all policies that inhibit the development and deployment of renewable technology in order to achieve the defossilisation of our economy". 

It implores them to back the Positive Power Plan and endorse four key policy shifts that are urgently required to avoid the catastrophes that will come with a continued rise in lethal Humidity.

About Fortescue 

Fortescue is focused on becoming the number 1 integrated green energy, metals and technology company, recognised for its culture, innovation and industry-leading development of infrastructure, mining assets and green energy initiatives.
It operates with two divisions – Metals and Energy. 
Fortescue  is  committed  to  producing  green  hydrogen,  containing  zero  carbon,  from  renewable electricity.
Green hydrogen is a zero-carbon fuel that, when used, produces primarily water. It is a practical and implementable  solution  that  can  help  revolutionise  the  way  we  power  our  planet:  helping  to decarbonise heavy industry and create jobs globally.
Fortescue is leading the green industrial revolution, building a global portfolio of renewable green hydrogen and green ammonia projects, while also leading the global effort to help decarbonise hard-to-abate sectors. This includes developing and acquiring the technology and energy supply to help decarbonise the Australian iron ore operations of one of the world's largest producers of iron ore, Fortescue Metals, by 2030 (Scope 1 and 2 terrestrial emissions).

Lethal humidity and heat are already upon us.  
Our actions today will determine how many millions of people die or are forced to migrate. 

World Leaders,

We, the undersigned, come from the world's leading research and academic institutions, and consist of a diverse range of climate scientists, public health experts, policy makers and industrialists. 

There is scientific consensus that rising humidity and heat pose a serious and growing threat to humanity. At temperatures as low as 30˚C, under conditions of high humidity, the human body struggles to cool down by sweating. Death can result.  

As temperatures increase, so does the potential for episodes of high temperature and high humidity beyond what humans and many mammals – including livestock, an important source of protein globally – can endure for more than a few hours.  

These impacts will not be equitable. Society's most vulnerable, such as the elderly, young children and the poor, will suffer the most. At population scale, this is called Lethal Humidity and its impacts will be felt globally, especially in tropical and sub-tropical regions. 

Some of the most populous regions on Earth are at risk, including parts of India, China, the United States, Indonesia, Pakistan, Bangladesh, Mexico, Northern Australia and many other countries across Africa, Asia, South America and Europe  

Rising humidity is also driving some of the most violent weather the world has seen and the threat will only grow as the world gets hotter. We must prepare for abrupt environmental and social change. 

Positive Power

World Leaders, we must move beyond all policies that inhibit the development and deployment of renewable technology in order to achieve the defossilisation of our economy.  

At least four key policy shifts are urgently required:    

1. Real Zero emissions – decarbonisation without offsets; new oil and gas projects severely restricted; strategic investment in and rapid approval of green energy projects
2. Removal of barriers to green industry, including fossil fuel subsidies, before 2030 
3. Matching of incentives and disincentives to risk with carbon pricing 
4. Economic stimulants to encourage green growth and transformation 

The direct impacts of lethal humidity with heat on human mortality will be widespread, as will the indirect effects associated with loss of labour, migration and geopolitical destabilisation.  As leaders, we must immediately address both – but never one at the expense of the other. 

We can still create a world fit for our children and future generations if we act now.

We call on you to endorse the Positive Power Plan.
