COP29 concludes with climate finance deal

The UN climate conference in Baku, Azerbaijan, concluded on 24 November with an agreement calling on developed countries to deliver $300 billion per year to developing countries by 2035 to drastically reduce greenhouse gas emissions and protect lives and livelihoods from the worsening impacts of climate change. “I had hoped for a more ambitious outcome – on both finance and mitigation – to meet the great challenge we face,” UN Secretary-General António Guterres said in his statement on COP29. “But this agreement provides a base on which to build.”

The forefront of climate litigation

Countries most affected by climate change – as well as citizens and non-profit groups – are increasingly turning to courts to compel governments and fossil fuel producers to address the climate crisis. One Caribbean island nation, Antigua and Barbuda, is at the forefront of this push. It has backed a UN General Assembly resolution requesting the International Court of Justice to weigh in on the obligations of states in respect of climate change.

Can AI help prevent the next wildfire?

Wildfires are raging across the globe, threatening lives, communities, and ecosystems. In 2024, we’ve seen unprecedented destruction, from California's vast landscapes to the heart of Canada to tropical forests in Central Africa. But there’s hope. Cutting-edge technology, including AI, satellites, and smart sensors, is stepping up to help us fight back and revolutionizing how we detect, predict, and respond to wildfires.

UN Biodiversity Conference

The Earth’s land and the ocean serve as natural carbon sinks, absorbing large amounts of greenhouse gas emissions. Conserving and restoring natural spaces, and the biodiversity they contain, is essential for limiting greenhouse gas emissions and adapting to climate impacts.Countries will meet at the UN Biodiversity Conference in Cali, Colombia, to accelerate action under the Kunming-Montreal Global Biodiversity Framework, the biodiversity plan reached in 2022.

UN Climate Conference

The Conference in Baku, Azerbaijan, is expected to focus on finance, as trillions of dollars are required for countries to drastically reduce greenhouse gas emissions and protect lives and livelihoods from the worsening impacts of climate change. The conference is also a key moment for countries to present their updated national climate action plans under the Paris agreement, which must limit global warming to 1.5°C above pre-industrial levels and spur investment in the Sustainable Development Goals.

UN Desertification Conference

This UN Conference will be a critical milestone in advancing global efforts to combat land degradation, desertification and drought, and promote sustainable development. Under the theme “Our Land. Our Future,” the conference will convene 196 countries and the European Union along with experts and civil society to promote urgent action. It is expected to be the largest and most ambitious summit on land and drought resilience, coinciding with the 30th anniversary of the UN Convention to Combat Desertification.
