Fire managers across the US Southwest are reckoning with strong winds that forecasters say could lead to explosive growth in wildfires this week. Hundreds of people were evacuated in numerous blazes that have scorched structures and signaled an early start to the fire season.

A wildfire on the outskirts of Flagstaff continued its run Wednesday though dry grass and scattered Ponderosa pines around homes into volcanic cinder fields, where roots underground can combust and send small rocks flying into the air, fire officials said. Aircraft was grounded for a second day due to high winds, and a major northern Arizona highway remained closed as smoke shrouded the air.

Between vast almond orchards and dairy pastures in the heart of California's farm country sits a property being redesigned to look like it did 150 years ago, before levees restricted the flow of rivers that weave across the landscape.

The 2,100 acres (1,100 hectares) at the confluence of the Tuolumne and San Joaquin rivers in the state's Central Valley are being reverted to a floodplain. That means when heavy rains cause the rivers to go over their banks, water will run onto the land, allowing traditional ecosystems to flourish and lowering flood risk downstream.

Iraq was hit Wednesday by its third heavy dust storm in two weeks, temporarily grounding flights at Baghdad and Najaf airports, as the weather phenomenon grows increasingly frequent.

Heavy winds have kicked up a towering wall of flames outside a northern Arizona tourist town, ripping through two-dozen structures and sending residents of more than 700 homes scrambling to flee.

Devastating floods in South Africa this week, as well as other extreme weather events across the continent linked to human-caused climate change, are putting marine and terrestrial wildlife species at risk, according to biodiversity experts.

Africa has already faced several climate-related woes in the past year: the ongoing fatal floods follow unrelenting cyclones in the south, extreme temperatures in western and northern regions, and a debilitating drought which is currently afflicting eastern, central and the Horn of Africa.

An Italian naval vessel specialized in marine pollution clean-up arrived Tuesday in waters off Tunisia where a tanker laden with diesel fuel capsized at the weekend.

The death toll from devastating floods in and around the South African port city of Durban has risen to 306, the government said, after roads and hillsides were washed away as homes collapsed.

Honda is investing 5 trillion yen ($40 billion) over the next decade in research, especially to realize a major shift to ecological electric vehicles, the Japanese automaker said Tuesday.

The products and services in the works will account for more than half of its 8 trillion yen ($64 billion) research and development budget in that time and will be tailored for each major market, the U.S., China and Japan.
