Rising temperatures are pushing malaria-carrying mosquitoes to higher altitudes, posing a lethal threat to pregnant women in previously unaffected regions.
Papua New Guinea's highlands are seeing an increase in malaria cases as mosquitoes move to higher elevations due to climate change.
Pregnant women in these regions are particularly vulnerable, with severe malaria increasing the risk of maternal and fetal complications.
The upward shift of malaria mosquitoes threatens to reverse global progress in malaria control.

— Sadie Ryan, associate professor of medical geography at the University of Florida.
Why this matters:
Climate change is expanding the range of malaria, endangering pregnant women in highland areas who lack immunity. This trend emphasizes a need for enhanced malaria control measures and healthcare access in vulnerable regions. Read more: Coronavirus, climate change, and the environment.
This summer's extraordinary heat is but a preview of what's to come: Humidity not only makes daytime highs more miserable, it extends the hotness through the night.
Researchers in heavily drilled Pennsylvania are adding to a body of evidence suggesting links between the natural gas industry and certain health problems.
Exposure to excessive heat during pregnancy has been linked to everything from preterm labor to low birth weight, and those risks are rising as the world warms.
The soot, known as PM 2.5, has been linked to cardiac arrest, asthma attacks and “premature deaths” from a range of cardiovascular and breathing disorders.
A photographer spent years documenti communities downstream of Alberta’s oilsands. Then he was invited to join Warren Simpson, dying from a rare form of cancer he believed to be linked to the mines, for his last breaths
