The impact of climate change on the Gulf Stream will have serious consequences for the weather in Europe and North America

According to one new study carried out by a team of Irish, British and German scientists and published in the journal Nature Geoscience (Caesar et. at the., February 25, 2021), human-induced climate change has resulted in a substantial reduction in the flow of the Gulf Stream. In addition, the researchers predict that if the trend continues, which is likely under current conditions, the degradation of the Gulf Stream will reach a “tipping point” beyond which the change will become irreversible, producing major negative impacts on human resources. weather patterns along the coasts of the North Atlantic in Europe and North America. The results of this study corroborate previous modeling that predicted the now documented slowdown.

The North Atlantic Gulf Stream, also known as the Atlantic Meridional Reversing Circulation (AMOC), originates near Florida, flows north along America’s east coast north, then moves east towards Europe, before diverging into several distinct currents. It is one of the major ocean currents in the world having a major influence on the global climate. In particular, the Gulf Stream exerts a moderating influence on the climatic regimes of eastern North America and western Europe. Without it, the weather conditions in these regions would be more extreme, with a greater amplitude of temperatures and precipitation, and a marked increase in severe storms, or even a deviation of the trajectories of winter storms over Europe. It would also accelerate sea level rise in these two regions.

The moderating effect of the Gulf Stream on weather patterns along the Atlantic coasts of the northern hemisphere is due to the enormous amount of hot water – over 20 million cubic meters per second – that it pumps into the North Atlantic, offsetting the cooler water of the arctic region to the north.

Researchers predict that the tipping point could be reached by 2100, after which the Gulf Stream would either degrade significantly or come to a complete stop. Once that happens, the change is likely to be irreversible, no matter how hard we try to moderate climate change.

Earth’s population is heading for a catastrophic 2.4-degree rise in temperature by the end of the century

The concentration of carbon dioxide on the planet has risen to a new high – 148% above pre-industrial levels.

Earth’s temperature in 2020 reached a record high in 3 million years. Countries’ current commitments to reduce greenhouse gas emissions are insufficient to prevent a climate catastrophe. UN Secretary General Antonio Guterres said this at the international conference Petersberg Climate Dialogue. Online organization on Thursday 6 May.

“Last year was another unprecedented period of extreme weather and climate disasters,” he said.

According to Guterres, “this is the highest level in 3 million years, when the temperature of the Earth was 3 degrees higher and the sea level was about 15 meters higher.”

“Last year was already 1.2 degrees hotter than preindustrial times – dangerously close to the 1.5 degree limit set by the scientific community. We are still heading for a catastrophic 2.4 degrees temperature rise by the end of the century. we are really standing on the edge of the abyss, “he stressed.

The UN Secretary General noted that the current commitments of countries to reduce greenhouse gas emissions are not enough to prevent a climate catastrophe.

“But if we work together, we can prevent the worst impacts of climate disruption and use the recovery from the COVID-19 pandemic to put us on a cleaner, greener path,” Guterres added.

Earlier, the UN said that it needed Global Zero Carbon Coalition… National governments must already take action to prevent further climate change and adapt to existing changes.

It was also reported that 2020 became the hottest year in Europe for 150 years. Temperatures on the continent have been elevated at all seasons.

New York climate summit meeting

After the young people, it is up to the leaders of the whole world to mobilize for the planet. The “Climate Action Summit” is due to open on Monday, September 23 in New York. Convened by the Secretary-General of the United Nations, Antonio Guterres, some sixty heads of state must present him with “Concrete and realistic plans” in order to save the objectives of the Paris agreement.

Signed in 2015, it was supposed to reduce global warming by 2100 to 1.5 ° C or 2 ° C compared to the pre-industrial period. However, the latest estimates from the Intergovernmental Panel on Climate Change (IPCC) conclude that temperatures have increased by 3 ° C… and up to 7 ° C for the most pessimistic forecasts revealed on September 17 by a hundred of French researchers and engineers.

Ambitious goals

Faced with the runaway climate change, Antonio Guterres called on States to “Reduce greenhouse gas emissions by 45% by 2030 and achieve carbon neutrality by 2050”. On the table, the issue of reducing greenhouse gases will rub shoulders with that of renewable energies, renewable infrastructure, sustainable agriculture, sustainable management of forests and oceans, means of resistance to global warming and of investing in the green economy.

“We need to profoundly change the way we produce our food, where the energy of our economies comes from, how our cities are organized, how we produce our energy”, the UN chief said last week.

Great absentees

60 heads of state and government were invited to New York, but not all of them attended. In the aftermath of legislative elections which failed to separate him from his rival, Israeli Prime Minister Benyamin Netanyahu canceled his trip to the UN. The leaders of the United States, Canada, Australia and Brazil also did not answer the call. Actors from civil society, local communities, private companies and international organizations were also invited.


The Earth’s Axis Shifts the Impact of Climate Change

Jakarta, CNN Indonesia –

A recent study revealed that human-caused climate change has shifted the Earth’s axis. Climate change has increased the melting of glaciers in arctic regions for decades.

The findings were published in the journal Geophysical Research Letters. Much redistribution of water has caused the location of the north and south poles to shift eastward since the mid-90s.

This causes the Earth’s axis to turn more inclined. According to USA Today, the Earth’s axis has moved about nearly four meters since 1980.

However, climate scientists say that the shifting of the Earth’s axis has yet to affect everyday life.
