Eric Grimsrud (Inter Lake Mar 17) wrote correctly, Earth’s climate is controlled by three variables: solar radiation, Earth’s reflection (albedo) of solar radiation, and atmospheric greenhouse gases. Everything else Grimsrud wrote you should forget.
Grimsrud claimed it is easier to predict long-term climate change than weekly weather. But meteorologists regularly make useful 1 to 6 day weather predictions, while our $100-billion climate models have not made a valid prediction, over-predict temperature, and do not agree with each other.
According to the rules of science, the climate models’ failure to make valid predictions requires we reject the alarmist climate-change hypothesis. That’s right, Obama’s changing America over a delusion.
A recent scientific paper found climate models’ representation of incoming solar-radiation contain spurious numerical errors up to 30 Watts per square meter for constant latitudes, while actual solar radiation is constant for each latitude. These numerical errors are 18 times greater than the calculated 1.68 Watts per square meter of warming (before feedbacks) due to all human carbon-dioxide emissions since 1750.
Rather than being concerned about climate change, alarmists should be concerned about the errors in their climate models.
Grimsrud claims atmospheric carbon dioxide is “out of control” implying we humans have caused a problem but he has no evidence to prove his case. On the contrary, evidence shows our atmosphere compensates for increases in carbon dioxide by reducing water vapor, a much more powerful greenhouse gas, to maintain a constant greenhouse effect.
A recent scientific paper compares radiation and cloud cover in the northern and southern hemispheres. The northern hemisphere has more land and therefore reflects more solar radiation. But our atmosphere mysteriously adds more reflective cloud cover in the southern hemisphere to equalize the reflection of solar radiation in each hemisphere.
Another recent scientific paper shows cosmic ray intensity and not atmospheric carbon dioxide correlates with temperature over the last 500 million years. More cosmic rays cool the Earth by forming more clouds.
To understand why climate changes, we must remove climate physics from politics and put it back in science where it belongs. Climate physics tells us we should not be alarmed about our carbon dioxide emissions because carbon dioxide does not control climate.
