## TL;DR

Climate change solutions span multiple sectors: Energy (renewable: solar, wind — now cheapest electricity in history), Transportation (EVs, public transit, cycling infrastructure), Food (plant-rich diets, reduced food waste), Buildings (insulation, heat pumps), Land use (reforestation, regenerative agriculture). The technology exists; political will and investment are the bottlenecks.

## Core Explanation

Solar: costs dropped 90% since 2010. Wind: onshore cheapest energy source per kWh. Heat pumps: 3-4x more efficient than gas heating. Electric vehicles: reach price parity with ICE by 2027 (BloombergNEF). Reforestation: natural carbon capture. Individual actions: reduce meat, fly less, electrify home, vote, talk about it. 'The greatest threat to our planet is the belief that someone else will save it' (Robert Swan).
