2024 saw record-breaking hurricanes, including Hurricane Beryl (the earliest Category 5 on record) and Hurricane Helene, which caused devastation in North Carolina. Heat waves were also severe, with Phoenix experiencing 113 consecutive days of 100°F+ temperatures, breaking the previous record of 76 days. Global temperatures were the hottest on record, surpassing 2023, with all top 10 hottest years occurring in the 21st century.
Heat waves and hurricanes became more severe due to climate change, which increases their frequency, intensity, and duration. Climate change also contributes to more extreme weather events like floods and storms.
2024 saw the discovery of a non-addictive pain medication that blocks nerve channels before pain reaches the brain. Researchers also found that vitamin D deficiency may not be as problematic as previously thought and that ancient brains preserved for thousands of years may provide insights into neurodegenerative diseases.
Public health in 2025 faces potential threats from bird flu (H5N1) and the politicization of science. However, advancements in mRNA vaccines and weight loss drugs offer hope for tackling major health challenges.
2024 was a breakthrough year for generative AI, with advancements in creating convincing audio and video. OpenAI's Sora video maker and improvements in AI-generated voice were notable. However, backlash grew over concerns about data usage and potential job displacement.
AI's energy demands are expected to rise, with concerns about the environmental impact of data centers. Microsoft is exploring reviving a nuclear reactor to power its data centers, highlighting the growing need for sustainable energy solutions.
AI agents are expected to become more prominent, offering more autonomous functionality without requiring constant user prompting. These agents could interact with other apps to perform tasks like booking plane tickets based on user preferences.
2024 brought heat waves and hurricanes, bird flu and breakthroughs, and an overwhelming amount of progress in AI.
