PyHydro | 3. Principles of Standardized Precipitation Index (SPI) Calculation

Introduction In the context of intensified climate change and frequent extreme droughts, how can we scientifically and objectively measure “how dry it is”? The answer from meteorologists is: the Standardized Precipitation Index (SPI). It does not depend on region, season, or units, providing a unified scale to inform you— the current level of precipitation anomaly … Read more

From Chimneys to Air: How CCUS and DAC Technologies ‘Capture’ Carbon Dioxide?

From Chimneys to Air: How CCUS and DAC Technologies 'Capture' Carbon Dioxide?

In addition to reducing emissions, can we also ‘capture’ the carbon dioxide that has already been produced? The answer is: Yes! CCUS and DAC technologies are becoming the ‘carbon capture tools’ to combat climate change. When we talk about addressing climate change, ’emission reduction’ is undoubtedly the core keyword. However, the reality is that some … Read more

Interesting Carbon Capture Technology – Direct Air Capture (DAC)

Interesting Carbon Capture Technology - Direct Air Capture (DAC)

Recently, I came across a project that captures carbon dioxide directly from the atmosphere, which was quite shocking. China’s annual carbon emissions reach 14 billion tons, and the concentration of carbon dioxide in the atmosphere is 0.04% (400 ppm). Who thought of this brilliant idea to capture carbon from the air instead of focusing on … Read more
