With a global temperature anomaly of 1.55°C over pre-industrial levels, 2024 was the hottest year on record due to an unparalleled increase in extreme weather events, including deadly hurricanes, floods, and sweltering heatwaves and wildfires. Millions have been relocated, thousands have died, and over $320 billion has been lost globally as a result of these disasters, which have been made worse by human-induced climate change. This concerning reality has prompted governments, organizations, and communities to expedite the creation of extreme weather and climate policy that prioritizes adaptation, mitigation, and resilience.

The pressing need to safeguard ecosystems, economies, and lives led to the development of new policies in 2024–2025 to meet these growing dangers. This article summarizes important extreme weather and climate policy that were established during this time, examines how extreme weather is influencing global climate policy, and provides answers to useful queries regarding their application.

What New Climate Policies Were Introduced in 2024-2025?

The unrelenting rise in extreme weather occurrences has sparked a global upsurge in new climate legislation. The following lists the main extreme weather and climate policy that were implemented or substantially revised in 2024–2025, along with a synopsis of their goals and parameters:

• EU Adaptation Strategy Update (2024): Building on the 2021 EU Adaptation Strategy, the European Commission’s Communication on Managing Climate Risks (2024) aims to make the EU climate-resilient by 2050. To combat heatwaves and flooding, which affected Europe with 188 occurrences in 2024, it focuses on urban adaptation strategies, comprising flood defenses and green infrastructure.
• UK’s Third National Adaptation Programme (NAP3) (2024): Initiated in the wake of England’s wettest 18-month period (October 2022–March 2024), NAP3 prepares the UK for escalating climate threats by addressing flooding, heatwaves, and wildfires through improved infrastructure resilience and early warning systems.
• UN’s Early Warnings for All Initiative Expansion (2024): To close the gap where only half of countries currently have adequate early warning systems, this project, which was stepped up in 2024, aims to ensure that all countries have robust systems by 2027. In 2024, it reacts to 151 meteorological phenomena that are unprecedented.
• US National Climate Resilience Framework (2024): This strategy, introduced to increase resilience against billion-dollar catastrophes (24 in the US in 2024), prioritizes equitable adaptation, focusing on vulnerable areas and upgrading infrastructure to withstand floods, wildfires, and storms.
• Global Buildings and Construction Climate Goals (2024–2025): As part of the COP30 preparations, the Global Status Report for Buildings and Construction 2024–2025 outlines ambitious goals for net-zero buildings through energy regulations and the integration of renewable energy sources, addressing storm and urban heat hazards.

How Are Extreme Weather Events Driving Policy Changes?

In 2024, there were 151 extreme weather events, including Hurricane Helene and Super Typhoon Yagi, which underscored the need for effective extreme weather and climate policy. Policy attention has switched to adaptation and resilience as a result of these catastrophes, which resulted in 1,700 fatalities and 824,500 displaced people.

For example, 24 billion-dollar disasters in the US prompted investments in hurricane-resistant infrastructure and flood barriers. There has also been an increase in public support for climate legislation, since research indicates that better policy support, especially in the Global South, is correlated with subjective attribution of extreme weather to climate change.

What Challenges Do These Policies Face in Implementation?

There are many obstacles in the way of implementing these extreme weather and climate policy. Funding shortages are still a significant problem; by 2030, developing countries would need $187–359 billion a year for adaptation, but present funding is insufficient, as seen in Canada, where convective storm modeling is difficult because of its localized character, inconsistent data, and geographical variances, making risk evaluations more difficult.

Additionally, as seen by the US’s NOAA staff reductions, which jeopardize climate monitoring capacity, political opposition and economic considerations might postpone action. To overcome these, international collaboration, more funding for climate services, and fair access to technology are necessary to guarantee that policies result in practical action.

How Can Technology Support These Climate Policies?

To operationalize the 2024–2025 climate policy, technology plays a crucial role. According to the Global Dangers Report 2025, AI-powered climate models provide hyper-localized projections that enable farmers and urban planners to prepare for the risks of heat and flooding. In nations like Bangladesh, the UN’s Early Warnings for All Initiative uses mobile technology to provide real-time notifications that save lives.

To locate energy assets in a way that is robust to climate threats, the UK’s National Energy System Operator (NESO), which was established in 2024, employs advanced analytics. To optimize their impact, it is still essential to guarantee vulnerable communities fair access to these technologies.

Frequently Asked Questions (FAQs)

Q1. Why are extreme weather events increasing in 2024 and 2025?

With a worldwide temperature anomaly of 1.55°C over pre-industrial levels in 2024, extreme weather events are becoming more frequent as a result of human-induced climate change. Because warmer air retains more moisture, higher temperatures intensify storms, heat waves, and precipitation.

Q2. How do new climate policies address vulnerable communities?

Communities most impacted by climate disasters are the focus of policies such as the US National Climate Resilience Framework, which encourages fair adaptation. Through readily available early warning systems, the UN’s Early Warnings for All Initiative seeks to safeguard people who are at risk.

Q3. What role does public opinion play in shaping climate policies?

Policy support is heavily influenced by public opinion, particularly when it comes to the connection between climate change and extreme weather. Subjective attribution of climate change to extreme weather increases support for policies such as carbon levies and renewable energy transitions, according to a 2025 study conducted in 68 countries.
