Below in italic is the AiG article written by Michael Oard. Let's dissect it.
Severe Difficulties with Secular/Uniformitarian Beliefs
Secular/uniformitarian scientists have great difficulty explaining any recent ice ages based on rates they observe today.
The insinuation there is that those scientists are atheists. Nothing could be further from the truth.

They have proposed dozens of hypotheses, but all have serious flaws. One problem is that the summer temperatures in the northern United States would have to cool more than 50°F (28°C) accompanied by a huge increase in snow.
Really, I wonder why he avoids naming those "dozens" of hypothesis. Maybe because there aren't dozens of hypothesis.

What would trigger or sustain such a dramatic climate change that would persist for thousands of years? David Alt of the University of Montana in Missoula recently admitted, Although theories abound, no one really knows what causes ice ages.
There's no doubt that whatever David Alt said concerning causes of ice ages, there is a context problem there with Oard's claim.
Ancient ice ages have been somewhat controversial over the years, but recently some uniformitarian scientists have come out with the shocking belief that some Proterozoic ice ages were global.
What do you say we substitute Oard's word "belief" with
EVIDENCE.
This belief is based on paleomagnetic data that supposedly shows certain rocks, believed to be from ancient ice ages, were marine and equatorial. Because of the reflection of sunlight from a white surface, it is likely that a glaciated earth would never melt.
Again, Evidence, not a belief. The paleomagnetic evidence shows at which latitude the glacial debris that was deposited was formed, which was very near the equator. Therefore .... duh
However, advocates of snowball earth state not only that such a glaciation completely melted but also that temperatures following glaciation ended up much warmer than today. Such a freeze-fry hypothesis indicates that the concept of ancient ice ages is unsound.
Again, Oard seems to ignore the
evidence, such as; Palaeomagnetism, Low-latitude glacial deposits, Open-water glacial deposits, Carbon isotope ratios, Banded iron formations, Cap carbonate rocks, Changing acidity, Distribution of the continents, to name a few. To ignore that
evidence is to deny the last ice age as well. And where is the evidence to support Oard's claim that the concept is unsound? Oh! There isn't any.
