Deep Dive
What were the major weather and climate events of 2024?
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.
Why were heat waves and hurricanes more severe in 2024?
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.
What were some unexpected health discoveries in 2024?
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.
What is the outlook for public health in 2025?
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.
How did AI evolve in 2024?
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.
What are the energy implications of AI in 2025?
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.
What new AI trends are expected in 2025?
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.
