Drought Shrinks Habitat for Large Western Mammals
A study finds historic drought in the American Southwest has reduced prime habitat for mule deer, black bears and cougars. Researchers used long-term GPS tracking to measure how drought changed those areas.

Small-scale irrigation as rain becomes unreliable
Climate change is making rainfall less reliable, so expanding irrigation is essential. Small-scale and solar-powered systems can help millions of smallholder farmers grow crops year‑round, but wider expansion needs large investment and better management.
Warm temperatures in pregnancy linked to loss of male fetuses in Sub-Saharan Africa
A study of nearly three million births across 33 Sub‑Saharan African countries found first‑trimester exposure above 20°C linked to higher loss of male fetuses. Authors cite the "frail male" idea and call for stronger maternal care.
Climate change and farming in North Kivu
In North Kivu, eastern DRC, changing rainfall and more extreme weather are damaging crops and food supplies. Research and local studies report shorter rainy seasons and heavier rains; experts promote irrigation, better planning and resilient seeds.
Warmer temperatures make invasive brown anoles more aggressive
A Tulane University study found that rising temperatures increase aggression in invasive brown anoles more than in native green anoles. Researchers tested pairs of lizards in controlled enclosures and say warming could favour the invasive species.
