Global environmental leaders gather Monday in Cali, Colombia to assess the world's plummeting biodiversity levels and commitments by countries to protect plants, animals and critical habitats.

The two-week United Nations Biodiversity Conference, or COP16, is a follow-up to the 2022 Montreal meetings where 196 countries signed a historic global treaty to protect biodiversity.

More than 100 wildfires stretched thousands of firefighters to the limit in northern Portugal on Wednesday, with seven deaths since the worst spate of fires in recent years spread out of control over the weekend.

Portuguese Prime Minister Luís Montenegro declared a state of calamity for the hardest-hit areas late on Tuesday, invoking powers to mobilize more firefighters and civil servants. He also called on police investigators to redouble their efforts to find those who started the fires and pledged help for those who have lost their homes or have been evacuated.

Since childhood, Loveness Bhitoni has collected fruit from the gigantic baobab trees surrounding her homestead in Zimbabwe to add variety to the family's staple corn and millet diet. The 50-year-old Bhitoni never saw them as a source of cash, until now.

Climate change-induced droughts have decimated her crops. Meanwhile, the world has a growing appetite for the fruit of the drought-resistant baobab as a natural health food.

Devastating floods through much of Central Europe and deadly wildfires in Portugal are joint proof of a "climate breakdown" that will become the norm unless drastic action is taken, the European Union's head office said Wednesday.

"Make no mistake. This tragedy is not an anomaly. This is fast becoming the norm for our shared future," said EU Crisis Management Commissioner Janez Lenarcic.

Firefighters on Monday battled flames spreading through a national park in Brazil that is enveloping Brasilia in smoke. It's the latest wildfire in the country, which is experiencing an historic drought.

More than 490 firefighters were trying to extinguish blazes that have already burned through 2,000 hectares (4,942 acres) of the conservation area of Brasilia National Park. There are four main fire fronts, all concentrated in the eastern region of the park, according to a statement from ICMBio, the government agency that manages the park.

Soldiers dropped sandbags from military helicopters to reinforce river embankments and evacuated residents as the worst flooding in years spread Tuesday to a broad swath of Central Europe, taking lives and destroying homes.

Heavy flooding has affected a large part of the region in recent days, including the Czech Republic, Slovakia and Austria. There have been at least 16 deaths reported in the flooding, which follow heavy rainfall across the region.

Five thousand firefighters struggled Tuesday to contain multiple wildfires raging across northern Portugal that are blamed for causing three deaths and forcing an unknown number of residents to flee their homes.

Some 100 fires reported by national authorities stretched the firefighting brigades. Authorities have yet to give figures on how many people have had to evacuate and how many homes have been lost.

The nations of Central Europe were bracing on Friday for severe flooding forecast to hit the Czech Republic, Poland, Austria, Germany, Slovakia and Hungary over the weekend.

Czech authorities were erecting metal barriers or protective walls from sandbags, while water was released from dams to make space in reservoirs. Residents have been warned to get ready for possible evacuations.

Even as she promoted her efforts to boost clean energy, Vice President Kamala Harris said in Tuesday's debate that the Biden-Harris administration has overseen "the largest increase in domestic oil production in history because of an approach that recognizes that we cannot over rely on foreign oil."

The comment by Harris, a longtime climate hawk who backed the original Green New Deal, surprised supporters and opponents alike — and conflicted with frequent boasts by Harris and President Joe Biden that they are champions in the fight to slow global warming.
