For decades, scientists believed the Arctic Ocean was sealed under a massive slab of ice during the coldest ice ages — but new research proves otherwise. Sediment samples from the seafloor, paired with cutting-edge climate simulations, show that the Arctic actually remained partially open, with seasonal sea ice allowing life to survive in the harshest climates. Traces of ancient algae, thriving only when light and water mix, reveal that the region was never a frozen tomb. This discovery not only reshapes our understanding of Earth’s past but offers vital clues about how the Arctic — and our planet — may respond to climate extremes ahead.

the 75% of greenhouse gas emissions linked to the energy system

the 25% of greenhouse gas emissions linked to food, farming, and deforestation

These numbers are approximately correct, but context is key...

we call on policymakers to adopt trade policies that catalyse sustainable commodity production and to shift public money from the livestock sector to plant-based proteins. This will also help limit the risk of tipping points in the biosphere – including dieback of the Amazon rainforest – and can liberate land for regenerating nature.

There it is! Reforestation is absolutely necessary, and without it, all of these emissions reductions will be too little too late.

Too often, ocean degradation is left out of climate discussions. We talk about carbon emissions, fossil fuels, and energy transitions, but rarely acknowledge the ocean’s central role in regulating the planet’s climate and sustaining life. When we ignore the ocean, we ignore both a major part of the problem, and the scope of the crisis. Without it, any serious discussion about climate change is incomplete.

Here’s what James Hansen stated in his post, Large Cloud Feedback Confirms High Climate Sensitivity 2025 — May, 2025

Earth’s albedo (or reflectivity) is the portion (percent) of incoming solar radiation that is reflected back to space. As shown in Fig. 1, in the period of precise satellite data (since early 2000), Earth’s albedo has decreased about 0.5%.

We described this change as a BFD (Big Fucking Deal) because it has staggering implications. Solar radiation reaching Earth is about 340 W/m2, averaged over Earth’s surface, so the 0.5% albedo decrease is a 1.7 W/m increase of absorbed solar energy.

A +1.7 W/m2 increase of absorbed solar energy is huge. If it were a climate forcing, it would be equivalent to a CO2 increase of +138 ppm. — James Hansen

• Through its 2021-founded subsidiary MyCarbon, Brazil’s meat processing giant Minerva Foods is emitting and selling carbon credits to big oil companies that are in a rush to move away from a polluting stigma.
• Some credit-obtaining projects, however, face criticism over a lack of transparency and procedural perils. The controversies include unfulfilled promises to restore degraded ecosystems, such as the biodiverse Cerrado pasturelands, and halt deforestation within Amazon areas.
• The case raises concerns that the carbon market may be rubber-stamping the maintenance of industrial activities with high ecological impact, without truthfully contributing to the reduction of greenhouse gas emissions and other environmentally damaging practices.

But I’m saying, as an environmentalist, we have failed to shift the narrative and we are still caught up in the same legal, economic and political systems.

For me, what we’ve got to do now is hunker down. The units of survival are going to be local communities, so I’m urging local communities to get together.

“While the world is debating the potential collapse of the AMOC in the North Atlantic, we’re seeing that the SMOC is not just weakening, but has reversed. This could have unprecedented global climate impacts.”

• In September 2024, Churna Island and the sea surrounding it became Pakistan’s second designated marine protected area, home to a variety of corals and serving as a nursery for fish.
• It followed the 2017 designation of the country’s very first MPA around Astola Island, a haven for coral, birds and sea turtles to the east.
• While Pakistan’s first two MPAs are small and have yet to be fully implemented, they represent baby steps in the country’s nascent effort to protect its marine environment.
• The country still has a long way to go to protect 30% of its ocean by 2030, as mandated by the United Nations Convention on Biological Diversity.
