"Climate injustice persists as those least responsible often bear the greatest impacts, both between and within countries. Here we show how GHG emissions from consumption and investments attributable to the wealthiest population groups have disproportionately influenced present-day climate change. We link emissions inequality over the period 1990–2020 to regional climate extremes using an emulator-based framework. We find that two-thirds (one-fifth) of warming is attributable to the wealthiest 10% (1%), meaning that individual contributions are 6.5 (20) times the average per capita contribution. For extreme events, the top 10% (1%) contributed 7 (26) times the average to increases in monthly 1-in-100-year heat extremes globally and 6 (17) times more to Amazon droughts. Emissions from the wealthiest 10% in the United States and China led to a two- to threefold increase in heat extremes across vulnerable regions. Quantifying the link between wealth disparities and climate impacts can assist in the discourse on climate equity and justice."

Climate is just one symptom of the fact that humanity is using equivalent resources of 1. 7 planet Earths, way beyond Earth capacity to regenerate
We are using future Earth resources to maintain unsustainable present economic growth destroying Earth ability to maintain life

Ipcc #ClimateReport projects that #climatechange will ⬆️ in all regions
More #heatwaves, longer warm seasons and shorter cold seasons, changes in precipitation patterns affecting flooding and drought
With every additional amount of global warming, changes will get larger

No one talks about the garbage island in the Pacific.

But it’s larger than France, Germany, and Spain combined.

And it’s leaking toxic chemicals into the fish you eat.

Here’s what you were never told about the Great Pacific Garbage Patch:

"In 2025, AI and climate change, two of the biggest societal disruptors we're facing, will collide.

The summer of 2024 broke the record for Earth’s hottest day since data collection began, sparking widespread media coverage and public debate. This also happens to be the year that both Microsoft and Google, two of the leading big tech companies investing heavily in AI research and development, missed their climate targets. While this also made headlines and spurred indignation, AI’s environmental impacts are still far from being common knowledge.

In reality, AI’s current “bigger is better” paradigm—epitomized by tech companies’ pursuit of ever bigger, more powerful large language models that are presented as the solution to every problem—comes with very significant costs to the environment. These range from generating colossal amounts of energy to power the data centers that run tools such as ChatGPT and Midjourney to the millions of gallons of freshwater that are pumped through these data centers to make sure they don’t overheat and the tons of rare earth metals needed to build the hardware they contain."

"Since 2018, carbon emissions from data centers in the US have tripled. For the 12 months ending August 2024, data centers were responsible for 105 million metric tons of CO2, accounting for 2.18% of national emissions (for comparison, domestic commercial airlines are responsible for about 131 million metric tons). About 4.59% of all the energy used in the US goes toward data centers, a figure that’s doubled since 2018.

It’s difficult to put a number on how much AI in particular, which has been booming since ChatGPT launched in November 2022, is responsible for this surge. That’s because data centers process lots of different types of data—in addition to training or pinging AI models, they do everything from hosting websites to storing your photos in the cloud. However, the researchers say, AI’s share is certainly growing rapidly as nearly every segment of the economy attempts to adopt the technology.

“It’s a pretty big surge,” says Eric Gimon, a senior fellow at the think tank Energy Innovation, who was not involved in the research. “There’s a lot of breathless analysis about how quickly this exponential growth could go. But it’s still early days for the business in terms of figuring out efficiencies, or different kinds of chips.”

Notably, the sources for all this power are particularly “dirty.”"

"As part of the U.S. pledge to cut its total greenhouse gas emissions in half by the end of the decade, compared to 2005 levels, President Joe Biden has vowed to eliminate all power grid emissions by 2035.

But there are 220 new gas-burning power plants in various stages of development nationwide, according to the market data firm Yes Energy. Most of those plants are targeted to come online before 2032. Each has a lifespan of 25 to 40 years, meaning most would not be fully paid off — much less shut down — before federal and state target dates for transitioning power grids to cleaner electricity.

The trend may continue. President-elect Donald Trump and his advisers have repeatedly vowed to scrap rules on power plant emissions, which could unleash even more fossil plant construction and delay retirements of existing plants.

In several parts of the nation, data centers are the largest factor behind the building boom, according to analysts and utilities, but the precise percentage of new demand attributable to data centers is not known. Power companies have also been bracing for other new demands, including a proliferation of new factories across the country and the transition to electric vehicles and home appliances such as heat pumps."
