How will ongoing and upcoming space missions contribute to our understanding of the solar system in 2025?

\"The continued solar activity from 2024's peak will offer increased opportunities to witness auroras in the Northern Hemisphere throughout 2025. This, coupled with multiple meteor showers, supermoons in October, and a lunar eclipse, creates a year of heightened astronomical visibility. The occurrence of supermoons may cause higher-than-normal tides.\

What were the key climate events of 2024 and their global implications?

2024 was the warmest year on record, exceeding the Paris Agreement's 1.5°C threshold above pre-industrial levels. This surge, partly driven by El Niño, is unlikely to be surpassed in 2025 due to the anticipated La Niña event, which typically cools global temperatures. However, 2025 is still projected to be among the three warmest years ever recorded.
