How has sea level changed over history?
Scientists think that in ancient times the global climate and sea level went through many cyclic changes. Why do they believe this and what is the pattern of the sea level according to written history? This post addresses the gross features of the global mean sea level (GMSL), and not minor variations and trends. (more…)

Beware of the bias
Everyone is biased
If you change the bias in lawn bowling, the ball curves in the opposite direction and finishes in a different position. Similarly, if you change the bias (assumptions) in a scientific investigation you may obtain a different outcome.
In this post we look at the occurrence of bias in scientific investigations. (more…)

The real climate change
Weather change is not climate change
“Climate change” is mentioned often today in a context that means “weather change”. There is a difference between weather and climate. Climate is the long-term weather pattern. Weather influences what clothes you wear on a given day, while the climate influences the contents of your entire wardrobe. (more…)

Is there a climate crisis?
Heavy snow has disrupted normal life in Athens. And more than 245 million Americans are expected to face temperatures below freezing in the continental U.S. over the next seven days. The Arctic air from a polar vortex has already set temperature records in numerous states. Record low temperatures are making life miserable in the U.S. The severe winter weather has sparked emergency declarations in at least seven states, including Alabama, Oregon, Oklahoma, Kansas, Kentucky, Mississippi and Texas. Air traffic was halted at a number of airports. Across the country, at least 36 people have died since the punishing winter weather began last week. It must be global cooling! That’s like what we hear when high temperatures are attributed to global warming. But of course this is weather not climate (which is the weather averaged over 30 years). (more…)

A robust climate?
“By not doing enough to fight global warming, we’re trashing the planet” says National Geographic magazine. “How hot can it get before truly catastrophic changes are set in motion?”. And Wikipedia warns of “abrupt climate change as it approaches and surpasses 2°C above pre-industrial levels”. It also mentions the possibility of “accelerated global warming”, “runaway climate change”, “climate collapse” and “climate apocalypse”. Others mention a “climate emergency”, “climate crisis”, “climate breakdown”, “irreversible climate destabilization”, “abrupt and irreversible environmental changes” and “interconnecting calamities”. That’s alarmist. It’s creating a culture of fear and panic. And climate change is blamed for any extreme weather. But are these warnings justified? (more…)

What about climate change?
Roy Morgan’s 2019 survey found that Australians regard environmental concerns as the major problem facing the world. This included climate change, water conservation, pollution, rubbish, famine, and cutting down rainforests. And economic concerns came next.
What does the Bible say about the natural environment? Should Christians care for the environment, or doesn’t it matter?
Biblical worldview
This post looks at the natural environment from an understanding based on the Bible, which is God’s message to us. This leads to different understandings compared to if we reject what the Bible says. It’s a theistic viewpoint, not an atheistic one. The Bible says that the universe was formed miraculously by God’s command (Ps. 33:6-9). People can look at the same world, but their interpretation depends on their worldview. It’s like wearing glasses. For example, clear glasses give a brighter view than sunglasses. (more…)

Life in the Ice Age
Scientists believe that the Earth goes through cycles of climatic change. Periods of lower temperatures are assumed to result in long-term periods of glaciation, which are known as an ‘Ice Age’. As the causes proposed for these Ice Ages seem to be deficient, there is reason to believe that there was only one Ice Age.
This post is based on a children’s book by Hughes and Cosner (2018).
Was there really an Ice Age?
Evolutionists say that there have been many Ice Ages throughout history (Appendix A). Actually there was only one Ice Age, and it was caused by Noah’s Flood. Though the Flood lasted only one year, its effects on the climate lasted for centuries! Hot underground water was a major source of Flood waters, so even after they retreated back into the oceans, the water stayed warm. Also, massive volcanic eruptions would have poured ash into the air, which blocked out much sunlight over the land. So the land would have been much cooler. Then some of the warm water evaporated into clouds which then dropped much snow over the cold land. Over centuries, this packed into huge ice sheets covering a third of earth’s land. We can even see the effects the snow and ice had on the earth today; the ice at the North and South Poles is left over from this (about 10% of the earth is covered in ice); the alpine glaciers; and the glacial landforms and sediments. Because these effects are seen on the current land surface, it is clear that the Ice Age occurred after the Flood. (more…)
