Study: Humans are causing an unprecedented increase in carbon dioxide levels in 14 million years
The project is being implemented by Yara Clean Ammonia, North Sea Container Line and Yara International. The project aims to significantly reduce carbon dioxide emissions by 2030.
It is noteworthy that carbon dioxide emissions resulting from global maritime navigation amounted to about 706 million tons in 2022. The cooperation in the fields of global maritime shipping comes with the aim of reducing the temperature on the planet by 1.5 degrees Celsius by 2030.
The ship's technical specifications were not revealed. It is only known that the ship Yara Eyde will operate along the sea route between Norway and Germany, and will perform maritime transport missions between the cities of Oslo, Porsgrunn, Hamburg and Bremerhaven, starting in 2026, which will allow reducing third-class exhaust emissions (scope 3) by 11 thousand. tons annually of carbon dioxide, with the contribution of Yara International, as a shipping company.
It is noteworthy that Yara International is a Norwegian chemical company, founded in 2004 after its separation from the Norsk Hydro subsidiary.
Yara International is a leading global company in the field of supplying mineral fertilizers, and has extensive experience in the field of ammonia used in its production, and sends its fertilizer products to Brazil in large numbers.
Report: The Earth is on the verge of catastrophic climate turning points!
It is now inevitable that 2023 will be the warmest year ever recorded by humanity, and perhaps the warmest in at least 125,000 years.
Multiple temperature records were broken, with average global temperatures in some periods reaching well above 1.5 degrees Celsius. The loss of Antarctic sea ice is accelerating at alarming rates, along with many other indicators of rapid climate change.
Most people expect that if a system, such as a person's body, an ecosystem, or part of the climate system, is exposed to stress, it will respond more or less predictably by multiplying the stress, impact, and so on.
However, sometimes a system under stress changes fairly steadily (or “linearly”), but then larger or abrupt changes can occur.
The climate system has many potential tipping points, such as ice sheets disappearing or dense rainforests becoming drier and more open. It will be very difficult, indeed impossible, to restore these systems once they pass the tipping point.
About 200 scientists from around the world published the new Global Turning Points report at the United Nations COP28 climate talks in Dubai.
The report identifies scientific aspects of “negative” tipping points in the Earth system, which can harm both nature and people, as well as potential “positive” societal tipping points that can accelerate sustainability action.
Turning points in the air, land and sea
After combing through scientific evidence for past and present changes, and taking computer model predictions into account, researchers were able to identify more than 25 tipping points in the Earth system, six of which were located in ice-covered parts of the planet (the cryosphere), including the collapse of plates. Massive glaciers in Greenland and various parts of Antarctica, as well as local capping of glaciers and melting of permafrost.
Sixteen points are located in the "biosphere," the sum of all the world's ecosystems, including widespread tree dieback in parts of the Amazon and boreal forests, and degrading savannas and drylands.
The researchers identified four potential tipping points in ocean and atmospheric circulation, including the collapse of deep-ocean mixing in the North Atlantic and in the Southern Ocean around Antarctica, and the disruption of the monsoon in West Africa.
Human activities are already pushing some of these things closer to tipping points.
The consequences of crossing these turning points can be difficult to understand. For example, if parts of the Amazon rainforest die, we will lose countless species, and global warming will worsen as billions of tons of carbon currently sequestered in trees and soil enter the atmosphere.
This could cause trillions of dollars in economic impacts and expose millions of people to extreme heat.
There is also the possibility of a negative upheaval in human societies, causing further financial instability, displacement or conflict. This would hamper our efforts to limit further tipping points in the Earth system, and could even lead to a shift to a social system characterized by greater authoritarianism, hostility, and isolation that could derail sustainability transitions altogether.
The Global Turning Points report shows that climate change is a major driver of most of these turning points, and the risk of exceeding these points can be reduced by quickly reducing greenhouse gas emissions to zero.
To help prevent tipping points in the biosphere, we will also need to rapidly reduce habitat loss and pollution while supporting environmental restoration and sustainable livelihoods.
