Can brightening clouds buy us time to fight climate change?

A group of leading scientists has outlined a research roadmap for testing the feasibility of artificially brightening Earth's clouds to reflect more sunlight and cool the planet. This strategy, known as marine cloud brightening (MCB), involves spraying saltwater into the air from ships to shade the surface of the Earth. However, there is still much uncertainty surrounding the potential risks and benefits of solar geoengineering techniques like MCB. The authors of the research paper want to proceed with caution and emphasize the need for stronger guidelines and regulations for such approaches.

DeepMind Wants to Use AI to Solve the Climate Crisis

DeepMind, the Google-owned AI lab, is using its AI expertise to address climate change in three ways: understanding climate change through better models for prediction and monitoring, optimizing current systems and infrastructure, and accelerating breakthrough science. AI's role in addressing climate change includes helping with mitigation, adaptation, addressing loss and damage, biodiversity, ecology, and more. However, access to data and collaboration with domain experts are crucial roadblocks that need to be overcome. DeepMind believes that AI, when wielded effectively, can be a transformative tool in solving climate change problems at scale.

Quadria to invest half its India capital in climate-related healthcare solutions

Singapore and New Delhi-based private equity firm, Quadria Capital, plans to invest around 50% of its capital in Indian healthcare entities that offer solutions to address climate change-related challenges. The firm aims to invest in businesses focused on virtual care delivery, home health services, preventive care services, and digital therapeutics. Quadria Capital believes that these models can help mitigate and adapt to climate change, such as rising air pollution and natural disasters. Currently, investments in climate-health initiatives are very low, with less than 2% of global climate adaptation funding directed towards health.

Amazon’s All-Powerful ‘Buy Box’ Is at the Heart of Its New Antitrust Troubles

The US Federal Trade Commission (FTC) has filed an antitrust case against Amazon, alleging that the company illegally monopolizes online shopping. The case revolves around Amazon's Buy Box feature, which the FTC claims is used as an anticompetitive weapon. The Buy Box allows Amazon to manipulate consumers and punish sellers offering lower-priced goods elsewhere. The FTC argues that winning or losing the Buy Box can have a significant impact on a seller's business, and Amazon allegedly rigs the contest in its favor. The government is seeking a federal court injunction to change how Amazon operates its store.

Businesses finding it tough to accomplish net zero goal, says EY's Amy Brachio

According to EY's global vice chair for sustainability, Amy Brachio, businesses are facing challenges in achieving their energy transition goals due to the global economic slowdown, inflation, and other factors. She emphasizes the need for companies to integrate sustainability into their corporate strategies. Many companies have already taken the easier steps towards reducing emissions, and now face the complexities and interdependencies involved in further steps. Brachio highlights the shift towards electric vehicles in the automobile sector and the use of clean fuels in shipping as examples of the transition providing growth opportunities. The COP28 UN Climate Change Conference's decisions, including the creation of a loss and damage fund, are seen as positive steps, but more funding will be needed to support developing nations in their fight against climate change.

Microplastics could be affecting the weather too

A recent study led by scientists from Shandong University discovered microplastic particles in cloud samples collected from Mount Tai in Eastern China. The study also suggests that these microplastics could potentially impact cloud formation and weather. The researchers found common plastics in the samples, with higher concentrations in low-altitude and denser clouds. Further analysis revealed that exposure to cloud-like conditions can change the composition of microplastics. More research is needed to understand the effects of microplastics on cloud interactions and the presence of toxic metals in the atmosphere.

The US tightens greenhouse gas emission standards for heavy-duty vehicles

The US Environmental Protection Agency (EPA) has introduced strict regulations on greenhouse gas emissions from heavy-duty vehicles, such as big rigs and buses. The aim is to reduce emissions from a significant source of climate change pollution. Heavy-duty vehicles currently account for 25% of transportation-related greenhouse gas emissions in the US. The EPA estimates that the new rules will result in a billion tons of emissions being avoided by 2055, equivalent to removing the pollution from 13 million tanker trucks' worth of gasoline. The regulations are part of wider efforts to address climate goals under the Biden administration and the Paris climate accord.

Negotiations on the new finance goal have faced challenges, with disagreements on funding amount, contributors, eligible projects, and time period covered. Developing nations argue that the NCQG should address their specific needs and priorities.

Kuaishou and Douyin were found to have prohibited products on their platforms despite taking some action.
