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.

A new report by the Financial Accountability and Corporate Transparency (FACT) Coalition looking at 230 environmental crimes in countries in the Amazon region provides new insights into how environmental crimes such as illegal mining, logging, and wildlife trafficking are being committed and how their associated profits are being laundered.

Many prosecutors and investigators are currently failing to “follow the money” in environmental crime cases, the report found. In fact, only one in three analyzed cases involved a financial investigation. As a result, many cases yield low-level arrests and seizures while those who are really responsible for the crime – and are benefiting financially from this $281 billion a year illicit economy – walk free. This creates a vicious cycle in which environmental crimes are widely perceived to be “low-risk, high-reward”, thereby attracting increasing interest from criminal groups seeking to benefit. (...)

PreviewA global treaty on plastics, which is being touted as the most important environmental treaty since the 2015 Paris Agreement, is set to be negotiated in South Korea over the next week.

At the fifth and final scheduled session of the UN’s Intergovernmental Negotiating Committee on Plastic Pollution (INC-5), member countries hope to finalise and approve the text of the “international legally binding instrument on plastic pollution”.

A successful treaty could have important implications for climate change.

The production, use and disposal of plastics is responsible for around 5% of global greenhouse gas emissions and they are typically made from fossil fuels. Plastics production is expected to be one of the leading drivers of oil demand growth over the coming years.

Measures to reduce plastics use will be a key part of the agenda, as around 90% of emissions from plastics come from production. The negotiations will see countries discuss setting targets, accountability and transparency measures.

Carbon Brief analysis shows that without any agreement to cut plastic production, emissions from plastics could consume half of the remaining carbon budget for limiting warming to 1.5C above pre-industrial levels.

One expert tells Carbon Brief that the best outcome possible for the negotiations is to ratify a global target to limit plastics production, coupled with legally binding national targets.

However, she warns that oil-producing countries are likely to veto any such proposal.

Below, Carbon Brief presents five key charts showing why the plastics treaty matters for climate change.
