Brazil: COP30 – Indigenous Climate Protestors take the house down

I have not seen much reporting but these indigenous climate protestors apparently came ready for a fight. The RT reporter says: Climate protesters barge into COP30 conference in Brazil wielding fists and flagpoles. Doors booted down, conference hall trashed.

Brian Mier has not yet reported on this, but a little earlier he stated

As US and European media and NGOs focus on out-of-context examples of individual fails by Brazil's government to delegitimize it's environmental record during COP 30, the US and Europe backslides on their commitments to fighting climate change. Excellent reporting in the Hindu.+ pic.twitter.com/r8MUEGqGSh

Xi Jinping: Honoring Commitments with Concrete Actions and Jointly Writing a New Chapter in Global Climate Governance

Remarks by H.E. Xi Jinping
President of the People’s Republic of China
At the United Nations Climate Summit

September 24, 2025

Your Excellency Secretary General António Guterres,
Your Excellency President Luiz Inácio Lula da Silva,
Colleagues,

This year marks the 10th anniversary of the Paris Agreement, a pivotal year for countries to submit their new Nationally Determined Contributions (NDCs). Global climate governance is entering a key stage. I wish to share with you three points. 

First, we must firm up confidence. Green and low-carbon transition is the trend of our time. While some country is acting against it, the international community should stay focused on the right direction, remain unwavering in confidence, unremitting in actions and unrelenting in intensity, and push for formulation and delivery on NDCs, with a view to providing more positive energy to the cooperation on global climate governance.

Second, we must live up to responsibilities. In the course of global green transition, fairness and equity should be upheld and the right to development of developing countries fully respected. The transition should serve to narrow rather than widen the North-South gap. Countries need to honor the principle of common but differentiated responsibilities, whereby developed countries should take the lead in fulfilling emission reduction obligations and provide more financial and technological support to developing countries.

Third, we must deepen cooperation. The world now faces a huge demand for green development. It is important that countries strengthen international coordination in green technologies and industries to address the shortfall in green production capacity and ensure free flow of quality green products globally, so that the benefits of green development can reach all corners of the world. 

Colleagues,

Let me take this opportunity to announce China’s new NDCs as follows: China will, by 2035, reduce economy-wide net greenhouse gas emissions by 7% to 10% from peak levels, striving to do better; increase the share of non-fossil fuels in total energy consumption to over 30%; expand the installed capacity of wind and solar power to over six times the 2020 levels, striving to bring the total to 3,600 gigawatts; scale up the total forest stock volume to over 24 billion cubic meters; make new energy vehicles the mainstream in the sales of new vehicles; expand the National Carbon Emissions Trading Market to cover major high-emission sectors; and basically establish a climate adaptive society.

These targets represent China’s best efforts based on the requirements of the Paris Agreement. Meeting these targets requires both painstaking efforts by China itself and a supportive and open international environment. We have the resolve and confidence to deliver on our commitments.

Colleagues, 

Great visions require concrete actions. Climate response is an urgent yet long-term task. Let’s all step up our actions to realize the beautiful vision of harmony between man and nature, and preserve planet Earth—the place we call home.

Thank you.

China does it again! Scientists decode ‘climate code’

Scientists decode ‘climate code’ of Early Cretaceous greenhouse world hidden in 140-million-year-old oyster fossils

By Global Times

By studying 140-million-year-old oyster fossils, a joint team of Chinese and international scientists has uncovered clues about Earth’s climate during the Early Cretaceous period, challenging the singular narrative of steady warming trend and offering new insights into future global climate predictions.

Using oyster shell fossils records and combined with high-resolution climate simulations, the study has, for the first time, reconstructed the seasonal fluctuations in sea surface temperatures during the greenhouse periods of 140 million years ago. It revealed marked seasonal temperature differences and periodic glacial melt events during the Early Cretaceous period (approximately 139.8 to 132.9 million years ago).

This discovery challenges the long-held belief that seasonal variations were weak and glacial activity was rare during greenhouse periods, revealing the complexity and variability of Earth’s climate under greenhouse conditions, offering a new perspective for understanding long-term climate evolution.

The research findings were published online in the international scientific journal Science Advances on May 3.

The research team, including Chinese scientists from the Institute of Tibetan Plateau Research of Chinese Academy of Sciences (CAS), has found that during the Early Cretaceous period – an era dominated by dinosaurs and characterized by a greenhouse climate – Earth still experienced significant seasonal temperature swings, and may even have had periodic glaciation, in stark contrast to the current state of permanent polar ice sheets.

Researchers explained that oyster shells and similar accretionary organisms grow in annual patterns resembling tree rings, forming alternating light and dark bands. During the hot summer months, the shells grow faster and are more porous, creating “light bands,” while in the colder winter months, growth of the shells slows and the structure of the shells becomes denser, forming “dark bands.”

These shell-bearing organisms act as natural time recorders, preserving detailed evidence of Earth’s climate and ecosystem evolution. Studying them can help guide future ecological research, according to Ding Lin, an academician at the CAS.

In this study, the research team analyzed growth lines on oyster fossils and used advanced instruments to examine their chemical composition, confirming that the fossils were well-preserved.

The researchers found that during the Early Cretaceous, winter ocean temperatures in the mid-latitudes of the Southern Hemisphere were 10 to 15 C lower than in summer – comparable to the seasonal temperature differences in that region today.

Climate simulations further suggested that seasonal glacial meltwater may have flowed into the oceans at the time, similar to the summer melting of glaciers on Greenland’s ice sheet today.

The study also underscores that climate change is not always a steady warming trend. Greenhouse gas increases can intensify seasonal extremes and increase the likelihood of unpredictable weather.

The study found that the brief glaciation events that occurred 140 million years ago may have been triggered by a combination of large-scale volcanic activity and changes in Earth’s orbit – reminding that local geological events, alongside human activity, could cause unexpected cooling even in today’s warming world.

Ding Lin said that this study opens a new window into ancient climate history. By challenging the simplistic view of the greenhouse climate, the research not only reshapes the understanding of Earth’s distant past but also provides valuable reference points for predicting future global warming trends.
