What Biden said:

I also convened my entire Cabinet as part of a whole-of-government response.  And that response is to increase the number and intensity of the extreme weather events and be wary — we’re going to be — use all the resources available to the government to do it.  Nobody can deny the impact of climate crisis — at least nobody intelligent can deny the impact of the climate crisis anymore.

What WH claims he meant to say:

I also convened my entire Cabinet as part of a whole-of-government response.  And that response is to [the] increase [in] the number and intensity of the extreme weather events and be wary — we’re going to be — use all the resources available to the government to do it.  Nobody can deny the impact of climate crisis — at least nobody intelligent can deny the impact of the climate crisis anymore.

What I think he was saying:

I also convened my entire Cabinet as part of a whole-of-government response [to climate change deniers].  And that response is to increase the number and intensity of the extreme weather events and be wary [climate change deniers] — we’re going to be — use all the resources available to the government to do it. Nobody can deny the impact of climate crisis — at least nobody intelligent can deny the impact of the climate crisis anymore.

Because why would people need to be wary the government was going to help them?

He's already threatened to increase the number and intensity of severe weather events. Said he'd use all the resources available to the government to do it. Told people to be wary because nobody intelligent can deny climate change anymore.
