Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

The International Energy Agency (IEA) reported that global coal demand is expected to reach unprecedented levels in 2024. In its latest report, "Coal 2024: Analysis and Forecast for 2024," the agency predicts coal consumption will climb to 877 crore tonnes, marking a new record.

The report notes that while global coal demand increased by 1% in 2023, the growth rate has slowed compared to previous years. In 2021, coal demand surged by 7.7% following the COVID-19 recovery, while growth rates moderated to 4.7% in 2022 and 2.4% in 2023.

[...]

China, the world's largest coal consumer, will significantly drive global demand. The IEA estimates China's coal consumption will grow by 1% in 2024, reaching 490 crore tonnes. India, the second-largest consumer, is expected to see a 5% increase, bringing its consumption to 130 crore metric tonnes—a level previously achieved only by China.

Conversely, coal demand in developed regions like the European Union and the United States continues to decline. The European Union’s demand is projected to drop by 12% in 2024, while the US is expected to see a 5% decline. However, these decreases are less steep compared to the significant drops in 2023.

If the goal is securing affordable access to the transit point over the long term, it is climate change, not Chinese influence, that U.S. policymakers should worry about.

Climate Change and Global Shipping

The article discusses how climate change is affecting global shipping and trade, particularly in two regions that are of interest to the US government: Greenland and the Panama Canal.

  • Greenland: Rising temperatures have led to significant ice melt, making the area more accessible for oil and gas drilling and mineral mining. This has attracted international interest, but also raises concerns about environmental harm.
  • Panama Canal: Climate change is causing droughts and rising sea levels, threatening the canal's lock system and freshwater supply. The canal authority has proposed a $1.6 billion project to secure freshwater.

The article also mentions that China and Russia are working together to develop Arctic shipping routes, and that the US government is paying more attention to climate change's impact on global shipping.

Trump's Interests

The article notes that Donald Trump wants to acquire Greenland and reclaim control of the Panama Canal, citing national security concerns. However, experts suggest that Trump's interests are also driven by climate change, which is making both regions more important for global shipping and trade.

Climate Change Consequences

The article highlights the consequences of climate change, including rising sea levels, droughts, and increased risk of environmental disasters such as oil spills. It also mentions that the Environmental Protection Agency (EPA) has promoted the use of toxic fertilizer, which has been linked to health problems.

Summary

The UN declared 2024 the hottest year on record, capping a “decade of deadly heat” where all 10 of the hottest years occurred.

UN Secretary General António Guterres urged urgent action to slash emissions and transition to renewable energy in 2025 to prevent further climate breakdown.

The World Meteorological Organisation highlighted record rainfall, flooding, cyclones, heatwaves, and wildfires, with 26 of 29 extreme events in 2024 linked to climate change.

Dangerous heat days increased by 41 this year, emphasizing the need for global cooperation to address escalating heat risks.
