1. **1.2 Degrees Celsius**:
The average global temperature increase since the late 19th century, driven predominantly by human activities releasing greenhouse gases into the atmosphere.
2. **2 Degrees Celsius**:
The critical threshold beyond which scientists warn of irreversible climate impacts, such as mass coral bleaching, intensified storms, and widespread species extinction.
3. **415 Parts Per Million (ppm)**:
The current concentration of carbon dioxide (CO2) in the atmosphere, the highest in human history and significantly above pre-industrial levels of around 280 ppm.
4. **2,000 Billion Metric Tons**:
The estimated remaining global carbon budget to have a 66% chance of limiting global warming to 1.5 degrees Celsius, highlighting the urgency of reducing emissions.
5. **3 Million Square Kilometers**:
The approximate annual loss of Arctic sea ice, accelerating global warming as the ice’s reflective surface is replaced by dark ocean water that absorbs more heat.
6. **1 Billion**:
The number of people vulnerable to climate-related risks, including food and water insecurity, forced migration, and health impacts exacerbated by extreme weather events.
7. **$54 Trillion**:
The projected economic cost by 2100 if global warming exceeds 2 degrees Celsius, underscoring the financial imperative of investing in climate mitigation and adaptation.
8. **Zero Net Emissions by 2050**:
The target set by many countries and businesses to achieve carbon neutrality, aiming to halt further climate disruptions and stabilize the Earth’s climate system.
9. **75%**:
The percentage reduction in global CO2 emissions needed by 2030 to keep global warming below 1.5 degrees Celsius, according to the IPCC’s latest assessment.
10. **Every Degree Matters**:
Each fraction of a degree of warming has profound implications for ecosystems, livelihoods, and future generations. Bold action today can still mitigate the worst impacts of global warming and pave the way towards a sustainable and resilient future.
