"Without #AMOC, the southern hemisphere warms more rapidly as heat is not passing through to the north. This lowers the thermal equator and takes the rain belts with them. Areas used to significant rainfall such as the northern part of the Amazon and southern Asia would see significant less rain."
"The Hadley cell, also known as the Hadley circulation, is a global-scale tropical atmospheric circulation that features air rising near the equator, flowing poleward near the tropopause at a height of 12–15 km (7.5–9.3 mi) above the Earth's surface, cooling and descending in the subtropics at around 30 degrees latitude, and then returning equatorward near the surface. It is a thermally direct circulation within the troposphere that emerges due to differences in insolation and heating between the tropics and the subtropics. On a yearly average, the circulation is characterized by a circulation cell on each side of the equator. The Southern Hemisphere Hadley cell is slightly stronger on average than its northern counterpart, extending slightly beyond the equator into the Northern Hemisphere. During the summer and winter months, the Hadley circulation is dominated by a single, cross-equatorial cell with air rising in the summer hemisphere and sinking in the winter hemisphere. Analogous circulations may occur in extraterrestrial atmospheres, such as on Venus and Mars. Global climate is greatly influenced by the structure and behavior of the Hadley circulation. […] The sinking branches of the Hadley cells give rise to the oceanic subtropical ridges and suppress rainfall; many of the Earth's deserts and arid regions are located in the subtropics coincident with the position of the sinking branches. The Hadley circulation is also a key mechanism for the meridional transport of heat, angular momentum and moisture, contributing to the subtropical jet stream, the moist tropics and maintaining a global thermal equilibrium."

"The amount of heat transported to the north Atlantic is huge. […] It’s enough to warm the entire region by 4.5°C on average which means that I’m cutting the grass in November rather than shovelling snow."

Thanks to your feedback, i just changed the names to have them all different and try to reflect the goals.
Only one account lives at Bluesky. The other four are older and live at four different Mastodon servers.

Cattle accounts for 36 percent of tree cover loss from agriculture

(Please read methodology notes in Alt text.)

percent of land with forests replaced by cattle (2001-2015) Brazil and Paraguay show large areas where cattle replaced more than 13% of tree cover Caution note: "By overlaying recent maps of commodity production areas with maps of historical tree cover loss, this indicator shows where previously forested lands have been replaced by agriculture. Critically, this does not necessarily imply that current-day farms or pastures were directly responsible for past deforestation events. Furthermore, this approach does not allow monitoring of the potential indirect effects of these commodities on deforestation—for example, where expansion of a commodity displaces other forms of farming that contribute to deforestation elsewhere."

Thank you.

Tree cover loss in areas of medium to high erosion risk, 2001-2024. Portugal wins on percentage points!

“This paper shows that as an underlying driver, international trade should not be ignored, and that consumer countries should play a role to – or be held accountable – for part of that deforestation as well."

Annual changes in deforestation footprints show that many developed countries, China and India have obtained net forest gains domestically at the expense of foreign forests Excerpt from Nguyen Tien Hoang & Keiichiro Kanemoto (2021): https://www.nature.com/articles/s41559-021-01417-z.epdf?sharing_token=gW0dAxz1m2PjWUhgENZUotRgN0jAjWel9jnR3ZoTv0MFqPG3Hup0UdoBt27CZ-9Dsh28L5LJnoS7rm_cBtC65hnHQw-G-vOTTxaw2kg3IE8eZXdHj8ATyI4CnLE8PqFzafqCkuaGmY9SCt-ZDdO7c4_bWbPL3pFBjLjFaOaj6KsNBADmCH2lehENx1lWrQEPHQiqCEPUZgrzW2aJjtSdGL2dZspkpk49SxH0sdaByqU%3D&tracking_referrer=www.carbonbrief.org

Enabling climate acceleration are economic sectors such as land use, China coal, Saudi Aramco, Coal India, Gazprom (Russia), National Iranian Oil — in that order.

Since 2021, China coal sends more carbon in the air than NATO equities and Arab states combined. The China coal sector is increasing capacity and already is delivering 12.7 Gt/year. Following the Paris Agreement, countries should aim for minus two percent of carbon-equivalent release, year on year. Instead activities ensure steady growth. The more carbon they already output, the more they grow. Notably, the amount of coal extracted in China not only forces the Greenhouse Effect more than the production from animals. The situation is much worse: China extracts coal at an ever increasing rate. (Since 2016.) From 2020, Xi Jinping had secured coal growth of 1%/year. China mined less coal when it worked on the Paris Agreement (signed in 2015). In other times, since 1999, they produce ever more emissions each year than the previous year. The trend remains at doubling delivery in two decades. The present document is part of the "Greenhouse Forcing" project and is available to re-use if under the CC BY-SA licence. Author: data.yt
