On 7 November, the opening session of the annual UN climate summit, COP30, took place in Belém, Brazil. The conference brings together world leaders for climate action negotiations. In a series of opening addresses, UN leaders spoke about our changing climate.
UN Secretary-General, Antonio Guterres said, “Too many corporations are making record profits from climate devastation – with billions spent on lobbying, deceiving the public and obstructing progress.” He went on to say, however, that, “The United Nations will not give up on the 1.5 degrees goal. Because another truth is evident: we have never been better equipped to fight back. A clean energy revolution has taken hold. Solar and wind are now the cheapest sources of power – and the fastest growing sources of electricity in history.”
Prof. Celeste Saulo, Secretary-General of the World Meteorological Organization, commented on the publication of its State of the Climate Update 2025 which shows the key climate trends and their impacts – “2025 is set to be either the second or third warmest year we have ever observed. The past three years have been the warmest three years on record.” She also pointed out that, “Science is not only warning us; it is equipping us to adapt.”

 On 7 November, the Met Office and the National Energy System Operator (NESO) announced our ongoing commitment to supporting the transition towards a future clean, resilient and affordable energy system. Steve Calder, Director of Government and Industry Relationships at the Met Office said: “Weather is the ‘fuel’ behind Britain’s clean energy superpower. Partnering with NESO, our trusted weather and climate intelligence will support the UK’s journey to clean, secure, and resilient energy. By fully realising the opportunities of weather as energy, we can help enable a more efficient infrastructure that not only provides clean power, but also protects consumers.”

 In new research published earlier this month, Met Office and University of Exeter scientists considered the influence of Arctic sea ice on winter weather conditions with a range of outcomes influenced by a ‘tug-of-war’ between the amount of sea-ice loss relative to background global warming.

In October, new research was published indicating that, whilst rising seas are irreversible on human time scales and among the most severe consequences of climate change, emissions released in the coming decades will determine how much coastlines are reshaped for centuries to come. New research shows that near-term mitigation could spare future generations around 0.6 meters of sea-level rise.

The fourth UK Climate Change Risk Assessment (CCRA4) is due to be laid in parliament by the UK Government in January 2027. The Community Review for the Technical Report is now open until Tuesday 2 December.
The CCRA4-IA Technical Report will synthesise the most up-to-date evidence on the 44 risks and opportunities the UK faces from climate change and assess the urgency of taking additional action to respond to these.
The Technical Report has been developed by a wide group of experts from academia, the private and third sectors. We are now inviting comments on the Technical Report from the wider scientific and policy communities. The purpose of the review is to ensure the Technical Report is capturing the breadth of evidence in a comprehensive and robust way.
