Total rise = 1.2 + 0.75 = 1.95°C. - Esdistancia

Understanding the Context

The global average temperature rise is not just a theoretical number — it reflects urgent environmental changes affecting weather patterns, ice melt, sea levels, and ecosystems worldwide. The 1.2°C threshold, established by the Intergovernmental Panel on Climate Change (IPCC), marks a critical turning point where risks increase significantly. Beyond this level, extreme heat events, intense storms, and disruptions to food and water supplies become more frequent and severe.

Adding the 0.75°C:
Recent observational data indicate that global temperatures have risen by approximately an additional 0.75°C since 2000, driven largely by greenhouse gas emissions from fossil fuels, deforestation, and industrial activity. This more recent figure helps frame short-term accelerating warming trends and underscores the need for immediate climate action.

Why Is This Total + 0.75 = 1.95°C important?

This combined figure serves several key purposes:

Key Insights

• Scientific Benchmark: It provides a clear, quantifiable milestone that scientists, policymakers, and the public can reference when discussing climate impacts.
  
• Policy Driver: Governmental commitments, such as those in the Paris Agreement, rely on tracking temperature increases toward these thresholds to assess progress and adjust targets.
  
• Public Awareness: Communicating cumulative warming helps convey the seriousness of ongoing climate change in a concrete, understandable way.

How Is Global Temperature Measured?

Global temperatures are tracked using a combination of:

• Land-based weather stations
  
• Ocean buoys and ships
  
• Satellite data
  
• Historical records compiled since the 19th century

By integrating data across over a century, researchers calculate both long-term trends and recent accelerations, like the 0.75°C increase beyond 1.2°C.

Final Thoughts

Why Does 1.95°C Matter for the Future?

Scientists warn that 1.5°C is considered a critical ceiling to avoid the most catastrophic climate impacts, while 2°C signals increasingly dangerous risks. At 1.95°C, we are already witnessing severe consequences — melting polar ice, rising sea levels, more intense heatwaves, and biodiversity loss.

Limiting warming to below 2°C requires rapid and deep reductions in greenhouse gas emissions across all sectors—energy, transportation, industry, and agriculture.

Conclusion

The total global rise of 1.2°C + 0.75°C = 1.95°C is more than a number—it represents a real, measurable shift in Earth’s climate system demanding urgent action. Understanding and communicating this milestone helps build momentum for meaningful climate solutions and ensures we stay informed about the changes shaping our planet’s future.
