EARTH’S ENERGY BUDGET

June 2024

Analysis of Earth’s Energy Budget shows the importance of clouds to the climate.  Since scientists do not understand cloud formation, it shows the limitations of our present understanding of the climate, and, in particular, shows the uncertainty of our understanding of what has caused the global warming over the last 150 years.

Holocene Climate – from 10,000 years ago to the present

May 2024

Our present geological period is the Holocene Interglacial.  The Holocene’s climate history shows a surprising number of disagreements among scientists as to temperatures and as to the causes of temperature changes.

Temperature Evaluation

February 2024

2023 was the warmest year on record.  What caused the warming?  What is the significance?  The effect of warming (good or bad) depends on where and when the warming occurs.  The world has many different climate regions, and so the effects of warming and other climate change must be evaluated on a regional basis.

CO2 History since 1827 shows how much climate science changes and how much uncertainty still exists as to the strength of CO2 as a greenhouse gas.

December 2023/January 2024

The conclusions in the 6 IPCC Assessment Reports as to the cause of global warming have changed with each new report, and the range of uncertainty as to the Sensitivity of the climate to rising CO2 levels remains large and has not been narrowed over the years.

MORE RAIN?  MORE DROUGHTS?  MORE FLOODS?  BUT THE IMPORTANT UNDERLYING TRENDS ARE THAT: (1) THE WORLD IS GETTING GREENER, AND (2) FOOD PRODUCTION IS SOARING.

November 2023

The changes in rain, droughts, and floods are relatively small, if any.  Of much greater significance is the increase in the world’s greenness and food production.

HOW MUCH OF POST-INDUSTRIAL GLOBAL WARMING HAS BEEN CAUSED BY THE SUN?

October 2023

One of the most important issues on which climate scientists disagree is how much of the post-industrial (since about 1880) global warming has been caused by the sun.

CHARLESTON IS THREATENED BY SEA LEVEL RISE AND HURRICANES – TYPICAL OF OTHER US COASTAL CITIES.

September 2023

Charleston is threatened by sea level rise (caused by climate change) and also by hurricanes (which are part of natural weather variability).  Unfortunately local, state, and national governments are not acting to protect Charleston’s residents.  Why is this?  How many other US cities on the Gulf and Atlantic coasts are similarly unprotected?

HEATWAVES – HOW MUCH HOTTER?  HOW MUCH MORE FREQUENT?

August 2023

The world is getting hotter. Heatwaves are becoming more frequent, but the amount and the significance of the increase is disputed. Coldwaves are becoming less frequent, and coldwaves cause many more deaths than heatwaves. Global warming at the current rate of about 1 C per century is clearly beneficial for the parts of the world that have winter, and it can be argued that it is net beneficial for the world as whole.
