Climate change refers to long-term shifts in global or regional climate patterns, including changes in temperature, precipitation, and extreme weather events, attributed largely to human activities. While global warming specifically refers to the increase in Earth's average surface temperature, climate change encompasses a broader range of environmental impacts resulting from this warming.
Key aspects of climate change include:
Addressing climate change requires urgent and concerted efforts at the global, national, and local levels. Strategies include reducing greenhouse gas emissions by transitioning to renewable energy sources, improving energy efficiency, implementing policies to promote sustainable land use and transportation, enhancing resilience to climate impacts, and fostering international cooperation. Individuals can also contribute by adopting sustainable practices in their daily lives, advocating for climate action, and supporting initiatives that mitigate climate change and its impacts.
Thorium (Th) is a naturally occurring radioactive element (atomic number 90) that has gained attention as a potential fuel for nuclear reactors. It is about three to four times more abundant in the Earth's crust than uranium and is primarily found in monazite sands.
Thorium itself is not fissile, meaning it cannot directly sustain a nuclear chain reaction. However, when bombarded with neutrons, thorium-232 can absorb a neutron and eventually transmute into uranium-233 (U-233), which is fissile and can be used as nuclear fuel.
