Update (3/21/2023) – HA
Last Monday, the Governmental Panel on Climate Change, the IPCC, of the United Nations, the UN, released the conclusion of the sixth report on the climate in the world, with warnings for the increase in temperature and the problems resulting from this warming. .
As previously mentioned, the expectation is that the global temperature will be 1.5ºC higher than in comparison with the pre-industrial era until the beginning of the 2030s, leading to extinctions in oceans and on land, problems in harvests and, the worse, reaching a point of no return.
The report’s warnings were reviewed by scientists from more than 195 countries. The document also points out that, despite low-carbon technologies and international commitments, the efforts defined in the 2015 Paris Agreement seem not to have been sufficient. So far, it is estimated that the planet has already warmed by 1.1°C from pre-industrial levels.

Hot summers in the Arctic show, for scientists, that the globe is approaching a tipping point, which would also lead to the death of corals and the melting of polar ice shelves that increase the level of the oceans.
Among the actions recommended are advancing the goal of zero carbon from 2050 to 2040, creating government actions to absorb carbon from the atmosphere through photosynthesis, in addition to investing US$ 400 billion to limit carbon emissions. There is also an emphasis on more use of clean and renewable energy by companies, combined with a search for ways to offset the impact in the case of companies that are unable to practice this change, such as the airline industry.
It is also worth pointing out that tropical regions are at the forefront of these dangers, including Brazil. It is expected that half of the world’s population could still be exposed to potentially fatal levels of heat by 2100.

Scientists predict that in 2024 the atmospheric phenomena El Niño and La Niña could increase the temperature of planet Earth by up to 1.5 °C compared to the pre-industrial period. According to reports from recent years, in 2022 the global average increased by 1.2 °C even in periods marked by the predominance of La Niña marked by cold temperatures.
“It’s very likely that the next big El Niño could bring us above 1.5°C,” said Adam Scaife, head of long-term forecasting at the UK Met Office. Unlike La Niña, El Niño results in the warming of the waters of the Pacific Ocean in its equatorial portion, resulting in enormous climate changes.

Recently, the World Meteorological Organization (WMO) released a statement informing that a year between 2022 and 2026 should break the record of 2016, becoming the hottest since researchers follow the variation of the planet’s global temperature, highlighting that there is a huge possibility of strong heat waves in 2023.
“There is a 93% chance that at least one year between 2022 and 2026 will become the warmest on record and remove 2016 from the top spot. that of the last five years (2017-2021) is also 93%”.
The WMO warned that 2022 was the tenth consecutive year that global temperatures reached at least 1°C above pre-industrial levels. According to the body linked to the United Nations (UN), for this year the forecast is that the global temperature will be between 1.08°C and 1.32°C above the average.
In a harsh alert to the authorities, the UN reinforces that in the last year several climate disasters have destroyed the infrastructure of cities and claimed the lives of hundreds of people. In addition, the entity warns of sea level rise that has doubled since 1993, increasing by almost 10 millimeters since January 2020, reaching a new record this year.
