Climate Central vice-president for science Andrew Pershing said the figures illustrated the "huge burden" the burning of fossil fuels imposed on people around the world

"Australia didn't have a particularly interesting summer this year, but in Africa it's just day after day after day of climate change just beating down on that continent."

Summary: The video is about the challenges of decarbonizing the world economy and why capitalism is not an effective solution, according to the guest speaker Brett Christophers. Christophers is interviewed by Aaron Bastani on Novara Media.

The conversation starts with the confusion around the term "Net Zero." Christophers explains the difference between Net Zero and real zero emissions. Net Zero allows emissions as long as they are offset by carbon capture or sequestration.

Christophers argues that governments are not serious about decarbonization because they continue to grant new oil and gas exploration licenses. He also criticizes the over-reliance on future, unproven technologies for capturing carbon emissions.

The interview then covers why electrification is critical for mitigating climate change. Christophers explains that most greenhouse gas emissions come from burning fossil fuels to generate electricity. Therefore, decarbonizing the electricity sector is the most important strategy.

The conversation then dives into the challenges of transitioning to renewable energy sources. Christophers acknowledges that solar and wind are not perfect solutions because they are intermittent sources of energy. He also discusses the land-use challenges of building large-scale solar and wind farms.

Nuclear power is brought up as a potential solution, especially for large companies that need consistent baseload power. Christophers says that governments should incentivize the development of all carbon-free energy sources, including nuclear.

The video concludes with Christophers arguing that capitalism is not a solution to the climate crisis because it prioritizes the interests of capital over the well-being of the planet.

India’s heat waves are attributed to a combination of short-term weather patterns and long-term warming trends fueled by human-caused climate change. Residents in India’s sprawling capital are often particularly affected, because dense buildings, roads, cars and air conditioners contribute to urban heat, experts say.

Four parties hammer out agreement filled with bad news for scientists

---

The nationalist, populist Party for Freedom, led by Geert Wilders, won 23% of the vote in the November 2023 House elections, putting Wilders—once a fringe figure who proposed a “head rag tax” on women wearing headscarves—close to the center of power. Since then, Wilders has been in contentious and often chaotic negotiations to form a government with three other parties, including the center-right party led by outgoing Prime Minister Mark Rutte, which saw its electoral share shrink to 15%. The governing plan endorsed by the four parties, which marks a crucial step in forming a new government, includes a series of harsh anti-immigration measures. Centrist and left-wing parties fiercely criticized the plan during this week’s debate.

Another sharp turn comes in environmental policy. The Netherlands, a major agricultural exporter, has more farm animals per square kilometer than any other country in Europe, and their waste emits high levels of nitrogen compounds that violate EU rules and harm the country’s ecosystems. Past government plans to tackle the issue have triggered massive protests by farmers and the rise of a new party, the Farmer-Citizen Movement, that won 4.7% of the vote and is part of the new coalition.

Aquatic life from coral reefs to fish in the Thailand's eastern gulf coast is suffering as sea surface temperatures hit record highs this month amid a regional heatwave, worrying scientists and local communities.

The once vibrant and colourful corals, about five metres (16 feet) underwater, have turned white in a phenomenon known as coral bleaching, a sign that their health was deteriorating, due to higher water temperatures, scientists say.

Sea surface temperatures in the Eastern Gulf of Thailand reached 32.73°C (90.91°F) earlier this month while underwater readings are slightly warmer, with dive computers showing around 33°C, data shows.

If water temperatures do not cool, more coral will die, Lalita said.

"It's global boiling, not just global warming," she said.

There may not even be enough vultures to eat our corpses at the end of the world.

Significance

Technological innovation is central to sustainable development, but representing novel technologies in systems models is difficult due to limited data on their past performance. We propose a method to model the feasibility space for novel technologies that combines empirical data on historical analogs and early adoption with a global integrated assessment model. Applying this method to direct air carbon capture and storage (DACCS), we find that the feasibility space is large, with DACCS contributing meaningfully to net-zero goals if it grows like some analogs and failing to do so with others. The results can be used to identify technology and policy features that may be important in enabling rapid adoption to avert the worst effects of climate change.

Abstract

Limiting the rise in global temperature to 1.5 °C will rely, in part, on technologies to remove CO2 from the atmosphere. However, many carbon dioxide removal (CDR) technologies are in the early stages of development, and there is limited data to inform predictions of their future adoption. Here, we present an approach to model adoption of early-stage technologies such as CDR and apply it to direct air carbon capture and storage (DACCS). Our approach combines empirical data on historical technology analogs and early adoption indicators to model a range of feasible growth pathways. We use these pathways as inputs to an integrated assessment model (the Global Change Analysis Model, GCAM) and evaluate their effects under an emissions policy to limit end-of-century temperature change to 1.5 °C. Adoption varies widely across analogs, which share different strategic similarities with DACCS. If DACCS growth mirrors high-growth analogs (e.g., solar photovoltaics), it can reach up to 4.9 GtCO2 removal by midcentury, compared to as low as 0.2 GtCO2 for low-growth analogs (e.g., natural gas pipelines). For these slower growing analogs, unabated fossil fuel generation in 2050 is reduced by 44% compared to high-growth analogs, with implications for energy investments and stranded assets. Residual emissions at the end of the century are also substantially lower (by up to 43% and 34% in transportation and industry) under lower DACCS scenarios. The large variation in growth rates observed for different analogs can also point to policy takeaways for enabling DACCS.
