Scientists have made a frightening prediction about the future of humanity on this planet.
According to experts in Canada, one One billion people — one-eighth of the current world population — will die from climate change if global warming reaches 3.6°F (2°C) or more by 2100.
Most of those who die will be poorer people living in developing countries, they say, while those contributing to the mass deaths will likely be the top executives of billionaire oil and gas companies.
Fatalities are caused by various disasters including floods caused by melted ice, wildfires, diseases, severe weather events like drought and many more.
The study authors urge governments and policymakers to urgently ban the use of fossil fuels such as coal and gas, which release large amounts of greenhouse gases into the air.
The researchers want to achieve a complete replacement of fossil fuels (coal, oil and natural gas). Pictured: emissions from a coal-fired power plant
The researchers say the deaths of a billion people are “comparable to negligent or negligent homicide.”
The leader of the study, Dr. Joshua M. Pearce of the University of Western Ontario, Canada, said such mass death was “clearly unacceptable”.
“It’s really quite scary, especially for our kids,” he said.
“Global warming is a matter of life and death for a billion people.”
“Almost everyone agrees that every human life is precious, regardless of age, cultural or racial background, gender or financial means.”
“That’s why the energy transition has to change much, much faster from now on.”
Greenhouse gases such as CO2 and methane are released when fossil fuels such as oil, coal and natural gas are burned to power cars, planes, homes and factories.
When these gases enter the atmosphere, they store heat and contribute to global warming.
As a result, the ice in the polar regions is already melting, and this meltwater is entering the oceans, gradually leading to rising sea levels and severe flooding.
Scientists believe that those who live in coastal regions and are the first to become permanently submerged are at greatest risk of death from sea level rise.
according to dr However, Pearce will also cause death from global warming in other ways, such as through the effects of heat waves.
We’ve seen higher average temperatures around the world, including the hottest month on record and the highest ocean temperature on record.
UNICEF recently launched the Children’s Climate Risk Index, which ranks countries based on children’s exposure to climate and environmental shocks such as hurricanes and heat waves
If global warming reaches or exceeds 2°C by 2100, it is likely that over the next century wealthier people will be the primary cause of the deaths of around 1 billion mostly poorer people (concept image)
“Climate change causes human deaths and can be divided into direct, intermediate and indirect deaths and their interactions,” said Dr. Pearce to MailOnline.
“Among the direct deadly effects of climate change are heat waves, which have already killed thousands of people through a combination of heat and humidity leaving the human body physically unable to cool itself through sweat.”
“Moderate causes of death include crop failures, drought, flooding, extreme weather conditions, wildfires and rising sea levels.”
“Especially crop failures can exacerbate global hunger.”
For the new study, published in the journal Energies, Pearce collaborated with Richard Parncutt from the University of Graz in Austria.
To confirm their prediction, the duo conducted a “major review” of more than 180 previously published articles from the scientific literature.
They compared different approaches to estimating future human death tolls from climate change, regardless of magnitude and at each location.
According to the results, the so-called “1,000-ton rule” is a fairly accurate way of predicting climate-related human mortality.

The 1,000 ton rule states that each time approximately 1,000 tons of fossil carbon is burned it will cause one future premature death.
However, the rule is a “best estimate of the order of magnitude” and the reality, according to Dr. Pearce to be more or less one person per 1,000 tons.
“The number of deaths caused will likely be between a tenth of a person and 10 people per 1,000 tons,” he said.
The scientist assumes that “mainly richer people” will be responsible for the deaths of a billion mostly poorer people in the next century, although he could not say what percentage of the billion will be poor.
“Most of the people who will die from climate change are poor people in developing countries,” he told MailOnline.
“Those earning the average income in a developed country will be able to buy their survival – e.g. B. by being able to move, offer food to the poor or pay for the air conditioning.”
The new study suggests immediate action to drastically cut carbon emissions lest the bleak forecasts come true.
This includes a complete replacement of fossil fuels, which are high carbon emitters – namely coal, oil and natural gas – with renewable energy sources such as hydro, wind, geothermal and solar.

He also wants technologies to be developed to capture and store CO2, in line with what the UK government is currently considering.
dr Pearce believes that phasing out fossil fuels in favor of renewable energy is plausible even for countries like India that rely so heavily on them.
“Even if we only look at it economically, for example, India is able to produce solar power more cheaply than any other source in history,” he told MailOnline.
“The transition to renewable energy should be viewed as an investment.”
“If India, and pretty much every other country, put money into solar and other renewable energy now, they will see an economic return over time, and that also means less pollution and all the many climate change problems.”
Fossil fuels versus renewable energy sources
Solar – Light and warmth of the sun.
wind – by wind turbines to drive electrical generators
Hydropower – caught from falling or fast flowing water
tide – Energy from sea level rise and fall
geothermal – Energy generated and stored in the earth
biomass – organic material that is burned to release stored energy from the sun
Although nuclear energy is considered clean energy, its inclusion in the list of renewable energies is the subject of much debate.
Nuclear energy itself is a renewable energy source. But the material used in nuclear power plants – uranium – is not renewable.
Renewable energy contrasts with the more harmful fossil fuels – oil, Money And gas.
They are considered fossil fuels because they were formed from fossilized, buried remains of plants and animals that lived millions of years ago.
Because of their origin, fossil fuels are high in carbon, but when they are burned, large amounts of the greenhouse gas carbon dioxide are released into the air.
