As we bid farewell to 2024, it's clear that this year has been a pivotal one for our planet's climate and environment. Here are 10 key impacts and developments that shaped the year and will continue to influence our path forward in 2025:
1. 2024: The Hottest Year on Record
2024 shattered temperature records, becoming the warmest year since record-keeping began. It was the first year to temporarily surpass the 1.5°C warming threshold compared to pre-industrial levels. While 2025 may not be as warm, we're rapidly approaching the point where we'll permanently cross this critical Paris Agreement benchmark.
2. Global Emissions Continue to Rise
Despite the acceleration of the global energy transition, with renewables now accounting for 30% of electricity production, emissions have yet to peak. In 2024, we released 37.4 gigatons of CO2 from fossil fuels into the atmosphere, along with another 4.2 gigatons from deforestation. Encouragingly, there are signs that China may be nearing its emissions peak.
3. Biodiversity: Progress and Setbacks
The EU's Nature Restoration Law marked significant progress for biodiversity, laying the groundwork for ambitious ecosystem recovery efforts. However, the COP16 biodiversity conference failed to reach funding agreements, underscoring ongoing challenges in biodiversity conservation.
4. The Return of Wolves
After decades of absence, wolves are re-establishing in several regions worldwide. This resurgence, often with sightings of breeding pairs, offers hope for the restoration of natural ecosystems and the balance they bring.
5. Plastic Treaty Negotiations Stall
Efforts to create the first Global Plastics Treaty have stalled, facing opposition reminiscent of climate action debates. With annual plastic production at 450 million tons and potentially tripling in three decades, setting production limits is increasingly urgent.
6. Landmark Climate Litigation
In a groundbreaking case, the European Court of Human Rights ruled against Switzerland for climate inaction, establishing that all states have a legal obligation to combat global warming. This decision sets a powerful precedent for future climate litigation.
7. Air Quality Standards Tightened
New air quality directives have halved the legal limits for major pollutants in the EU. This presents significant challenges for many regions required to rapidly implement stricter air quality measures.
8. Energy Transition Challenges**
Despite advancements, various regions lag in their renewable energy transition, producing less electricity from renewable sources compared to others that have exceeded 50% reliance on renewables. Governments are now accelerating approvals for wind and solar projects and investing in major initiatives like offshore wind farms.
9. Drought Relief, But Long-Term Concerns Remain
Late 2024 brought much-needed rainfall, alleviating immediate drought conditions in several regions. However, the earlier critical water shortages highlight the urgent need for sustainable water management strategies in the context of climate change.
10. Extreme Weather Events Become the New Normal
Devastating floods and other extreme weather events in 2024 are stark reminders of their increasing frequency and intensity due to climate change. Such events are now twice as likely and up to 12% more intense, emphasizing the need for comprehensive climate adaptation measures.
As we look toward 2025, these developments underscore the urgent need for continued action on climate change, biodiversity protection, and sustainable resource management. While challenges are immense, so too are the opportunities for positive change.
