Climate change is unarguably the most urgent issue threatening human society. The global average temperature in 2024 was the highest in recorded history, reaching 1.55 degrees Celsius above pre-industrial levels, according to the World Meteorological Organization. Increasing global temperatures lead to extreme weather events around the world, including heat waves, droughts, extremely heavy rainfall, and strong hurricanes, that affect our livelihoods in many ways. For instance, World Weather Attribution -- a network of researchers from the US, the UK and several other European countries -- claimed that the hot, dry, and windy conditions exacerbating the January 2025 wildfire in Los Angeles, which led to the loss of more than 28 lives and 10,000 homes, were about 35 percent more likely due to global warming.
