NASA space mission takes stock of carbon dioxide emissions by countries
https://phys.org/news/2023-03-nasa-spac ... arbon.html
by Sally Younger, Jet Propulsion Laboratory
A pilot project has estimated emissions and removals of carbon dioxide in individual nations using satellite measurements.

A NASA Earth-observing satellite has helped researchers track carbon dioxide emissions for more than 100 countries around the world. The pilot project offers a powerful new look at the carbon dioxide being emitted in these countries and how much of it is removed from the atmosphere by forests and other carbon-absorbing "sinks" within their borders. The findings demonstrate how space-based tools can support insights on Earth as nations work to achieve climate goals.

The international study, published in Earth System Science Data and conducted by more than 60 researchers, used measurements made by NASA's Orbiting Carbon Observatory-2 (OCO-2) mission, as well as a network of surface-based observations, to quantify increases and decreases in atmospheric carbon dioxide concentrations from 2015 to 2020. Using this measurement-based (or "top-down") approach, the researchers were then able to infer the balance of how much carbon dioxide was emitted and removed.

'Aim higher, act faster, or risk losing it all': Climate change report offers 'final warning'
Source: The New Daily

Humanity has had its “final warning” on the state of our climate, according to an alarming new scientific report.

More than 300 scientists signed off on the latest report from the Intergovernmental Panel on Climate Change, with the most authoritative global body on climate change urging countries to “aim higher, act faster, or risk losing it all” in its final report of the 2020s.

The IPCC Climate Change 2023: Synthesis Report, compiled by hundreds of scientists from 67 countries, was released on Monday, and it draws together the contributions of the IPSS’s sixth assessment cycle.

Court Rules Greta Thunberg and Others Can Sue Sweden for 'Insufficient Climate Policy'
by Jessica Corbett
March 21, 2023

Introduction:
(Common Dreams) A Swedish court on Tuesday ruled that hundreds of youth climate activists including Greta Thunberg can collectively sue Sweden for the government's "insufficient climate policy."

More than 600 people under age 26, including 20-year-old Thunberg, signed the 87-page document that is the basis for the lawsuit, which was filed in Stockholm in November and coincided with a march through the city.

"Sweden has never treated the climate crisis like a crisis," Anton Foley of the youth-led group Aurora, which prepared and filed the class-action suit, said at the time. "Sweden is failing in its responsibility and breaking the law."

The Nacka District Court determined Tuesday that the case can proceed and gave the Swedish government three months to respond.

"The district court has today issued a summons in a high-profile class-action lawsuit," the court said. "In the case, demands have been made for the district court to determine that the state has an obligation to take certain specified measures to limit climate change."

Millionaires will burn through 2/3 of world's carbon budget by 2050
To limit global warming to below 1.5°C, we can only burn a certain amount of carbon.

But millionaire emissions alone will deplete 72 per cent of this allowance before 2050, according to a paper published in the latest Cleaner Production Letters journal.

“Continued growth in emissions at the top makes a low-carbon transition less likely, as the system's capacity to decarbonize,” the scientists warn.

I know we have 2 or 3 climate deniers on this forum. I have to ask, what are you thinking when you see graphs like this?

Do you really imagine yourself more qualified than legions of experts with PhDs, who've studied this subject in exquisite detail, for decades? What exactly do you find so difficult to accept?

What's your alternative theory?

Rising temperatures are pushing India towards the deadly "wet bulb" threshold
https://qz.com/rising-heat-pushes-india ... 1850277293
India is moving towards fatal climatic conditions. This year saw the country’s hottest February in 122 years, and it is only likely to get worse.

The central and western regions of the hot tropical country are expected to experience heat waves in March-May, according to the India Meteorological Department (IMD). Summer temperatures in northern India regularly soar beyond 40°C in May and June, the hottest months of the year. Topping 50°C is unusual, but that is happening, too.

Climate scientists are now worried about an increased possibility of deaths if human body temperatures exceed the “wet bulb” threshold of 35°C. A Lancet study found a 55% spike in fatalities in India between 2000-2004 and 2017-2021 due to extreme heat. This is besides the loss of labour hours and the resultant loss of income.
