The Supreme Court heard its first global warming case yesterday and they'll look at the scientific data to behind the crisis. Meanwhile, we see new data about our warming planet every day.

After issuing its decision on wetlands protections last week, the Supreme Court once again made headlines in environmental news this week: The Court decided to hear the case about whether the federal government is required to regulate greenhouse gases.

In a landmark victory for religious freedom, the Supreme Court unanimously rejected the Bush administration's claim that it can bar a small congregation in New Mexico from using a hallucinogenic tea to connect with God during its rituals.

Chief Justice John Roberts led the court in its religious freedom decision and moved decisively to keep the government out of a church's religious practice. Federal drug agents should have been barred from confiscating the hoasca tea of the Brazil-based church, Roberts wrote in the decision.
