Predictions of future climate change require a clear and nuanced understanding of Earth’s past climate. University of Hawai‘i at Mānoa oceanographers solved a controversy that has been debated in scientific literature for decades by fully reconciling climate and carbon cycle trends of the past 50 million years. Their research was published in Throughout Earth’s history, global climate and the global carbon cycle have undergone significant changes, some of which challenge the current understanding of carbon cycle dynamics. Less carbon dioxide in the atmosphere cools Earth and decreases weathering of rocks and minerals on land over long time scales. Less weathering should lead to a shallower calcite compensation depth (CCD), which is the depth in the ocean where the rate of carbonate material raining down equals the rate of carbo
Nonprofit efforts The nonprofit group Ke Kula Nui O Waimānalo (KKNOW), whose aim is to promote health and support the self-sustainability of the Waimānalo community, has partnered with other nonprofits, businesses and governmental agencies to provide food for Waimānalo families. Since mid-March, the group has distributed 24,000 prepared meals and 3,550 boxes of fresh produce. KKNOW also delivered seeds and seedlings of traditional Hawaiian crops such as kalo (taro) and ʻuala (sweet potato) to families and community members who are vulnerable to food insecurity, economic instability and other social challenges. The goal of KKNOW is to build community resilience by helping fellow Native Hawaiians grow their own food before further disruptions strike, said Kirk Dietschman, president of Ke Kula Nui O Waimānalo and a co-author of the paper.
