Severe droughts limit Amazonian communities' access to basic services

A recent study found that nearly 50% of non-Indigenous localities and 54% of Indigenous villages in the Brazilian part of the Amazon basin are prone to isolation during severe droughts. Severe droughts result in extended periods of low water levels, affecting communities' access to goods, services, healthcare, education, and livelihoods.

Pacific cod can’t rely on coastal safe havens for protection during marine heat waves, OSU study finds

A new Oregon State University study found that young Pacific cod in near shore safe havens were severely affected by recent marine heat waves in the Gulf of Alaska. The researchers estimated that only the largest 15-25% of the island's cod population survived, leading to significant changes in abundance, growth rates and diet.

Non-native plants and animals expanding ranges 100 times faster than native species, finds new research led by UMass Amherst

A new research study led by UMass Amherst found that non-native species are expanding their ranges much faster than native ones, with a speed of 35 kilometers per year on their own and 1,883 kilometers per year when humans factor in their role. This means that native species cannot keep up with climate change without human help.
