Studying the difference between climate and climate change is a complex field of research. A methodological approach to easily understand the difference is remembering that climate has an envelope of natural variability whereas climate change introduces anomalies in this envelope. On a long term ave...

Interested researchers may also find a recent post about in phase and out of phase studies to understand the climate crisis informative.

Orbital Forcing as a Natural Variable in Climate Science

In this post, I have added a link to the preliminary study about recoded major earthquakes.

A major earthquake occurred off the coast of Japan yesterday. Newton’s universal law of gravitation formulated orbital forcing using the masses of celestial bodies and the distance between them. It would be intuitive to imagine that tide level fluctuations, which get higher during full moon phase, s...

Many people talk about the climate crisis to explain tragic events. Even though attributing the climate crisis to natural variability and human effect due to higher greenhouse emissions is a complex research, there are simple intuitions. Cyclic moon phases and associated tide levels happen naturally...

Even though the Environmental Protection Agency (EPA) of the United States was established in 1970, the idea of greenhouse gases affecting Earth’s energy balance was first suggested by Joseph Fourier in the early 19th century. Modeling of climate change attempts to use Earth’s energy balance in orde...

Seeing in the news a lake in the Sahara desert after recent rains there makes you wonder if this occurred due to natural variability in climate or man made climate crisis. Watching news about hurricanes Helene and Milton also makes you wonder whether they are caused mainly by natural variability or ...

Professor Michael Mann is one of the leading climate scientists and researchers of climate change. If I remember correctly, he was one of the research scientists who presented their research analyses at the annual conference of the American Geophysical Union in San Francisco in 2008. He presented co...

Gravity is one of the most fascinating forces of nature. When we watch news about the manmade Space Station, we are reminded that planet Earth is the biggest known natural spaceship. When we see energetic human beings on Earth lack energy and become freely floating human beings aboard the Space Stat...

Starting at a young age, I have been wondering about Monsoon rains because of the nature of flooding they cause in Asia. Just recently, there was sad news of fatal landslides in India because of Monsoon rain. Monsoon rains have been observed for the ages. Its current scientific explanation is that i...

A recent report by the Copernicus Climate Change Service of the European Union’s Earth Observation program shows that the year 2023 was the hottest on record, which spans more than a century and a half. The National Oceanic and Space Administration of the United States describes El Niño and La Niña ...

In over a century of recorded precipitation data, California had the wettest water year in 1983; a water year in the hemisphere runs from the beginning of October of the previous year to the end of September of the current year. That year nearly coincided with the extreme drought conditions in 1984 ...

I think that more people than not aren’t fully aware that the planets are in a state of continuous motion. The rotation of the earth on its axis gives us days and nights. Its orbital motion around the sun gives us seasons and years. Its cyclic orbital motion along with that of its moon gives us anal...

A peer reviewed journal paper at the following link has uncovered the predictability of meteorological variability using analogous orbital forcing. Validation of predicted meteorological drought in California using analogous orbital geometries It analyzed cyclic drought conditions in California. Thi...

It appears to me that our people are disproportionately inclined more toward spirituality than science. Even though my curiosity about both started early on in life, I have had a long personal journey in shifting my focus toward science. The experience has been rewarding in terms of making me more k...

This water year, which runs from the beginning of October of 2022 and runs through the end of September of 2023, California and other parts of the United States have seen lots of precipitation. The deluge in California this winter season is attributed to atmospheric rivers. So far in this season, el...

The history of Galileo Galilei has it that science and The Vatican have not been in the best of terms. Back on June 18, 2015, Pope Francis published an encyclical titled Laudato Si' in an effort to address climate change. Definitely, the climate crisis needs addressing. Attributing climate change to...

I have read that one of the agenda of the recent U.S.-Africa Leaders Summit was climate crisis. I am not sure if the delegations of Africa's counties to the summit included climate scientists that advise policy makers. I have long concluded that one of the ways to address climate crisis is getting a...

The predictability of meteorological variability is potentially a helpful scientific resource for the International Drought Resilience Alliance , which was in the news recently. I am not sure if there are Ethiopian researchers who are or may want to involve in this drought resilience alliance. If I ...

When you imagine future as a moment in space, it may sound daunting at first thought. A simple way to think about it is that if one goes from point A to point B and then to point C, you have a construct of a line on which future falls. The linear construct makes future appear as if it doesn't go bac...

The recent news from Ethiopia about the newly built Abrehot Library in Addis Ababa is encouraging. I am sure that libraries like this one are invaluable for advancing academic discourse in the country, in east Africa, and beyond. I presume that its management has made or would make arrangements for ...
