Trees are essential to life on Earth. They support ecosystems, store carbon, provide clean water, improve our health, and offer countless benefits to people and nature. In a new study, researchers modeled the future climate exposure (areas where trees will experience conditions they have never faced before) of more than 32,000 tree species worldwide. Their findings reveal that many trees will face conditions far outside what they currently experience—especially under high greenhouse gas emission scenarios.

New research from UC Davis, the Chinese Academy of Sciences and Texas A&M University reveals that massive emissions, or burps, of carbon dioxide from natural earth systems led to significant decreases in ocean oxygen concentrations some 300 million years ago.   

Long-term exposure to wildfire smoke may increase the risk of heart failure (HF), especially in older adults, women and vulnerable populations, according to a study published today in JACC, the flagship journal of the American College of Cardiology. In this first national, population-based study to examine how prolonged wildfire smoke exposure impacts HF risk, compared to other types of air pollution, researchers found that as the level of air pollution from wildfire smoke increased over a two-year period, the risk of developing heart failure also increased.

A study conducted by Dr. La Zhuo and colleagues from the Institute of Soil and Water Conservation at Northwest A&F University, published in Frontiers of Agricultural Science and Engineering, provides the answers to these questions (DOI: 10.15302/J-FASE-2024585).
