World Precipitation Rate: A Global Perspective

The world precipitation rate is the average amount of water (rain, snow, sleet, or hail) that falls from the atmosphere back to Earth, measured across the planet over a given time (per year, per day, or per hour). It can be expressed as: Total volume of water (in km³ per year) Depth equivalent (in mm/year over Earth’s surface) Rate (e.g., mm/day or mm/hour when averaged) 1. Global Average Annual Rainfall On average, about 505,000 km³ of water falls as precipitation each year: 398,000 km³ over oceans 107,000 km³ over land (Wikipedia – Precipitation) This translates to an average global precipitation of: ~990 mm per year across Earth’s surface ~715 mm/year over land only Alternative estimates put the figure slightly lower at ~954 mm/year (~486,000 km³ total precipitation) (Wikipedia – Earth Rainfall Climatology) Converting to a Rate 990 mm/year ≈ 2.71 mm/day ≈ 0.11 mm/hour 954...

Highlights: UN Climate Change - COP28 At UAE

  The quotes and updates from the COP28 conference highlight several key points: Droughts as Silent Disasters: UNCCD Executive Secretary Ibrahim Thiaw emphasizes that droughts often go unnoticed, causing silent devastation and neglect. The Global Drought Snapshot report underlines the increasing severity of drought events globally. Solutions for Drought Resilience: Sustainable land management, nature-positive farming techniques, and efficient water management are highlighted as solutions to reduce the impact of drought on crops and incomes. Early warning systems and disaster preparedness are crucial for global drought resilience. Climate Action Misalignment: UN Chief António Guterres points out the misalignment between countries' climate action plans (Nationally Determined Contributions) and scientific goals. Emissions are projected to rise, posing a challenge to limiting global temperature rise. Methane ...
