WIRED・15 minutes read
Bill Nye discusses various scientific topics on Twitter, highlighting the proven theory of evolution and the use of genetic engineering. He explains how scientists determine past temperatures, differentiate COVID variants using DNA sequencing, and describes the phenomena of hurricanes and volcanic eruptions in a simple and engaging manner.
Insights
- Evolution is a scientifically proven theory, not just a mere idea, demonstrating the fundamental concept of biological change over time.
- The intricate processes of the Earth's systems, such as the rain cycle and volcanic eruptions, are driven by complex interactions, showcasing the interplay between various elements like oceans, air temperatures, and tectonic movements to create natural phenomena.

Recent questions
How do scientists determine temperatures from thousands of years ago?
Scientists determine temperatures from thousands of years ago by studying minerals and fossils. By analyzing the composition and characteristics of these materials, researchers can infer past climate conditions and temperature fluctuations. This process provides valuable insights into the Earth's climate history and helps scientists understand long-term climate trends.
What is the difference between hurricanes and typhoons?
Hurricanes and typhoons are named differently based on location and language. In general, these weather phenomena are the same, but they are given different names depending on where they occur. Hurricanes are tropical cyclones that form in the Atlantic Ocean and northeastern Pacific Ocean, while typhoons are tropical cyclones that form in the northwestern Pacific Ocean.
How do scientists differentiate COVID variants?
Scientists use DNA sequencing to differentiate COVID variants. By analyzing the genetic makeup of the virus, researchers can identify specific mutations that distinguish one variant from another. This information is crucial for tracking the spread of different variants and understanding their potential impact on public health.
What is genetic engineering?
Genetic engineering involves complex processes and understanding genomes. Scientists manipulate the genetic material of organisms to achieve specific traits or characteristics. By altering DNA sequences, researchers can create genetically modified organisms with desired traits, such as increased crop yield or disease resistance.
How does the rain cycle affect droughts?
The rain cycle does not have agency and does not make decisions; as the ocean warms, the air becomes drier, leading to increased droughts. The process of evaporation, condensation, and precipitation in the water cycle is influenced by various factors, including temperature changes. As the ocean warms, more water evaporates into the atmosphere, leading to drier air and potentially contributing to increased drought conditions in certain regions.

Climate Change Impact on Natural Disasters
- The rain cycle does not have agency and does not make decisions; as the ocean warms, the air becomes drier, leading to increased droughts. Volcanic eruptions are caused by small shifts in tectonic plates over geologic time scales, even though they may seem infrequent on human time scales. Hurricanes can drop billions of gallons of water, with category six hurricanes dropping millions of tons of water, equivalent to billions of gallons.
