Global biodiversity report shows “catastrophic decline” in wildlife populations – “In just my lifetime, 50 years, we’ve seen a decline of 73 percent in the average size of these wildlife populations”

By Molly McCrea 18 October 2024 (CBS News) – A shocking new report on global biodiversity is detailing what it calls “a catastrophic decline” in wildlife populations ahead of a major international conference on biodiversity. On Monday, 21 October 2024, the United Nations will convene a two-week conference in Cali, Colombia called COP16. On the agenda […]

June 2024 sizzled to 13th straight monthly heat record – “It’s not that records are being broken monthly but they are being shattered by very substantial margins over the past 13 months”

By Seth Borenstein 7 July 2024 (AP) – Earth’s more than year-long streak of record-shattering hot months kept on simmering through June, according to the European climate service Copernicus. There’s hope that the planet will soon see an end to the record-setting part of the heat streak, but not the climate chaos that has come […]

Difference between modelled and reported methane intensities by type of company. Modelled emissions are compared with the methane emissions reported by each company in its sustainability reporting or its public communication. The global average ratio on this set of companies is 16.1, with a relative standard deviation of 79.3 percent. Each type of company within this set does not contribute similarly to these global metrics. Integrated companies have the highest average ratio between model and reporting out of all the types of companies, at 19.2 and a relative standard deviation of 64.7 percent, which means that some Integrated companies reporting are much closer to the values for their corresponding model than others. National oil companies (NOCs) have the lowest median ratio with 4.0 but their average is the second highest at 15.2, strongly influenced by one of the companies in the category that has a factor of 51.2, while the remaining 4 have an average of 6.2. Independent companies have the lowest average with 12.6 and a relative standard deviation of 65.2 percent, which shows the importance of the regions of operation in the results of different models.

We used satellite imagery and AI to see who’s keeping their climate pledges – Almost none of the signatories of the Global Methane Pledge are following through on their commitment – On average, companies emit methane intensities 16 times larger than reported

By Antoine Rostand 17 July 2024 (Fortune) – Committing countries or companies to climate pledges doesn’t guarantee that those pledges will be honored. After all, the planet is getting a great deal hotter every year, with the record-breaking temperature in India in May just the latest example. If companies and countries were fully honoring their […]

Dengue cases in Guatemala, Mexico, and Honduras, 2023-2024 and 5-year average. In the Region of the Americas, the number of dengue cases recorded during the first half of 2024 exceeded the maximum number of cases historically reported in a year, as compared to all previously recorded years. As of epidemiological week (EW) 23 of 2024, 43 countries and territories in the Region of the Americas have reported 9,386,082 cases of dengue; this number is twice as high as the number of cases recorded throughout 2023, 4,617,108 cases.

Dengue fever: CDC issues alert amid U.S. and global spike in cases – In 2024, cases of dengue fever in the Americas have reached record-breaking levels, with more than 9.7 million reported cases, twice the number for the entire year in 2023

By Finn Cohen 27 June 2024 (Healthline) – As cases of dengue fever rise worldwide, the Centers for Disease Control and Prevention (CDC) issued an advisory for physicians, public health authorities, and the public in the United States to be alert to the trend. So far in 2024, cases of dengue fever in countries in the Americas have reached record-breaking […]

Flooded Brazil “ghost town” a climate warning to world, UN advisor says – “It was underwater for almost 40 days. There wasn’t even any rats running around. Everything had died.”

By Jake Spring 26 June 2024 SAO PAULO (Reuters) – Record floods that killed over 170 people and displaced half a million in southern Brazil are a warning sign of more disasters to come throughout the Americas because of climate change, an official at the United Nations’ refugee agency said on Tuesday. Roughly 389,000 people, opens […]

(A) The AMOC strength at 1000 m and 26°N, where the yellow shading indicates observed ranges (60, 61). The cyan-colored lines indicate the magnitude of FH. The red arrow indicates the AMOC tipping point (model year 1758; fig. S1, A and B), and the blue sections indicate the 50-year periods used in (B) to (D). Inset: The hosing experiment where fresh water is added to the ocean surface between 20°N and 50°N in the Atlantic Ocean (+FH) and is compensated over the remaining ocean surface (−FH). The black sections indicate the 26°N and 34°S latitudes over which the AMOC strength and freshwater transport (FovS) are determined, respectively. (B to D) AMOC streamfunction (Ψ) and Atlantic meridional heat transport (MHT; see also fig. S2) for model years 1 to 50, 1701 to 1750, and 2151 to 2200.

Marker for the collapse of key Atlantic current discovered – “We are approaching the tipping point”

By Stephanie Pappas 9 February 2024 (Live Science) – Scientists have discovered a key warning sign before a crucial Atlantic current collapses and plunges the Northern Hemisphere into climate chaos. The Atlantic Meridional Overturning Circulation (AMOC) carries warm water north from the Southern Hemisphere, where it releases heat and freezes. The freezing process concentrates salt […]
