We often think of evolution happening over long time periods but that can be misleading especially in situations when long term events like climate change are responsible.
"North American migratory birds are becoming smaller as the planet warms due to climate change, a new study finds.

Researchers from the University of California, Los Angeles (UCLA) examined more than 30 years of data for adult male birds across 105 avian species that migrate through North America. They found that between 1989 and 2018 the birds' body masses declined by about 0.6% on average, according to an Oct. 27 study in the journal Nature Ecology and Evolution"

So, what's causing birds to shrink, especially over such a relatively short time period? Scientists suspect that climate change is the most likely culprit, and birds are adapting accordingly.

"If you're a larger person and you're in a cold environment and let's say you have a very small friend, you will probably be able to withstand the cold a little bit better than a smaller person would," Youngflesh told Live Science. "This really comes down to surface area and volume. As a larger person, you'll be losing less heat than a smaller person. The same thing applies to birds."
It's unfortunate that some creationists' organizations, like Discovery Institute, AIG and Reasons to believe have built in denial that react in a variety of ways against the science.

More science fiction from the esteemed scientist, any tall tale to make their agenda fearful.

Neither fiction nor fear are in the OP. There is, however, data.

Change according to genetic variation is not evolution.
This is something that isvery clearly explained by AiG.

You are simply attempting to define evolution as NOT evolution along the lines that make denial less obvious.

Evolution is the process by which populations of organisms change over generations. Genetic variations underlie these changes.

Better luck next time.

1). If change according to genetic variation is not evolution, what is it?
2). If evolution is not change according to genetic variation, how would you define evolution?

So lets see climate change causes evolution and climate change is caused by man and his industrial pollution from coal, gas/diesel cars/trucks/etc..

So man a million to billions of years ago was causing evolution from their pollution . I wonder what they were polluting the earth with back a million+ years ago.

Are you just being silly, or, is that serious.

Evolution is caused by environmental changes. The cause of these environmental changes (human or other) is not important.

Again standing back looking at all this.. there is a pattern here. I am surprised most don't see it. Its ok I know you don't see it :)

So here in this story what is left out is "A growing body of research suggests a warming world could mean smaller birds with longer wings, but nothing about the findings is settled."

Yeah there is no proof here what so ever " there is no remaining plausible hypothesis except for climate change.” This is what "Morgan Tingley, a UCLA ecologist and the study’s senior author" said. Does this matter "there are other studies that show seemingly opposite results." "In certain places birds appear to be getting heavier or developing shorter wings. In one study of California birds, researchers found that body mass increased (albeit by small amounts) over 40 years"

Shall I go on? :) So this climate change those that believe in it can also be said to be in denial no? I think that door swings both ways no matter how much be think it only swings one way.

He MUST defend AIG or he will be considered an apostate. Just the thought that genesis is may not be the literal truth is attack on his belief and belief trumps science. AGI needs believers to keep the billions rolling into their Ark Encounter amusement park.

Evidence is not proof, but you know. The difference between science and religious belief and science is science is based on evidence while religion is based on simply on belief. There are multiple contradictory religious beliefs many of which do not demand denial of evoluiton or climate change.

The industrial evolution is dated back to ~1880. Before the industrial humans did not consume enough fossil fuels to have an effect on climate. It is not human use of fossil fuels it is there overuse.

In science the theory with the most evidence is the reigning theory.

Their is evidence that:
  • The world will likely exceed 1.5C between 2026 and 2042 in scenarios where emissions are not rapidly reduced, with a central estimate of between 2030 and 2032.
  • The 2C threshold will likely be exceeded between 2034 and 2052 in the highest emissions scenario, with a median year of 2043.
  • In a scenario of modest mitigation – where emissions remain close to current levels – the 2C threshold would be exceeded between 2038 and 2072, with a median of 2052.
One result of higher emissions are many more billion dollar weather events causing flooding in coastal cities, wildfires in Western and NW US and desertification with not enough ground water to maintain like cities Phoenix and Los Vegas. But keep blinders and ear plugs handy to ward off the evidence.

AIG is just as bad as evolutionist. The only difference is they reject evolution and an old earth. But they agree basically with everything else stated by science, they are not true literal Biblical creationist. They are only part literal Bible creationist.

AIG is just one of the main creationist organizations that promotes belief trumps science that does not affirm a literal reading of genesis. We can speculate over their motivations but not over the damage they are causing.
