Good morning, I'm Dana Taylor and this is five things you need to know Wednesday, the 26th of July, 2023.

A federal judge in Oakland blocks a Biden administration policy that limits migrants access to asylum.

An Atlantic ocean current could collapse and UPS and teamsters avoid a massive strike by reaching a tentative agreement.

A federal judge in California struck down a new Biden administration policy that sought to limit the number of migrants seeking asylum at the US-Mexico border.

The ruling is a major blow to the White House's efforts to stem migration.

U.S. District Court Judge John Tigerer of the Northern District of California, President Obama pointee, ruled Tuesday on behalf of immigrant rights groups.

The groups had challenged a Biden policy requiring migrants heading to the US border to first seek protection in Mexico before attempting to do so in the US.

In his judgment, Judge Tigerer wrote that the rule is both substantively and procedurally invalid and said the hastiness of the Biden administration's push to implement the policy, quote, denied the public a meaningful opportunity to comment on the rule, unquote.

The judge delayed his ruling from taking effect for two weeks, the Department of Justice filed a notice that it planned to appeal the decision.

An Atlantic ocean current could collapse soon. For more on the possible effects, we're joined by USA Today Breaking News reporter, Doyle Rice.

It's good to talk to you, Doyle.

So first, can you please explain what the Atlantic, Meridian oil, overturning circulation or AMOC is and how it works?

Yeah, it's a natural part of the Earth current system, kind of underwater streams that go from the depths of the ocean up to the surface and around the entire Atlantic.

Believe it or not, these currents affect our weather. These underwater currents affect the atmosphere and can change weather for us here above the surface.

And how might climate change cause the AMOC to collapse? I mean, it sounds like the premise for that movie with Dennis Quaid and Jake Gyllenhaal the day after tomorrow.

Yes, the premise of that movie was an instantaneous shutdown or collapse of the ocean current and that caused almost immediate climate changes.

And while the climate changes that were anticipating would occur, they probably wouldn't occur as fast as they did in that movie.

And as far as how our own climate is changing the current, yeah, it has to do with how much salt is in the water.

See what's happening is the ice sheets on a green land are melting and that's fresh water and that gets into this current and can change it from being its normal salty water.

Self to fresh water or brackish water and that can really mess up the current.

So if the AMOC does collapse, how would that affect weather patterns?

Yeah, they're saying that there would be more sea level rise along the east coast of the United States.
