• There is a warmering of the Northern Hemisphere,compared to the Southern Hemisphere.
  
• The majority of the years after 2000 exceed the long-term average; an upward movement is evident in the uncertainty band (grey ribbon).

Ethical reflection
Open climatic data helps in creating transparency and accountability. Uncertainty should be depicted through visualisations and not deceptive axes or truncated scales.

conclusion The gradual increase in the global temperatures depicted here depicts the narrative of the human activity on the earth. A single degree is important- rainfall patterns, ice caps melting. These open NASA data serve as a lesson in history, but also act as a reminder of how we should hurry up and be open and transparent in dealing with climate change.
