USF to Host Global Climate Summit

Gov. Jerry Brown’s Global Climate Action Summit is coming to USF Sept. 11–14.

The summit will bring scientists and leaders from around the world to the campus and San Francisco to discuss how nations, states, businesses, and other groups can combat climate change. Co-organized by Brown, former New York Mayor Michael Bloomberg, and others, the summit aims to inspire worldwide resolve to take action.

Climate Risks for Mining

The climate risks that extractive industries face include the rise of extreme and unpredictable weather impacting upon mode of mining activities, mining sites and their surrounding communities and environments. This will not only affect profitability and labour conditions. For example floods can disrupt the tailing of mines sending excess polluted water into the storm drains, placing surrounding communities at significant risk of polluted water. In turn there’s a predicted scarcity of water and consequential negative impacts upon hydrological systems as they adapt to changing climatic conditions. The impact of potential infrastructure damage and energy stress due to climate change upon mining activities is another risk that has not been appropriately assessed by many companies and governments.

The Saint and the Dynamo in the 21st Century

Twenty-first century human beings are needy creatures. Extending beyond the bare necessities of food, water, clean air, and shelter, our needs and wants require vast amounts of mineral resources and energy. A critical concern is the relationship between the spiritual life and energy consumption. This reflection has been prompted in part by the Affordable Energy Proposal released by the EPA last week to replace the Obama administration’s Clean Power Act. Ostensibly, both documents aim to address climate change by mandating electrical utilities to reduce the emissions of  climate change-inducing carbon and fine particulates, which have been connected to respiratory problems like asthma.

Let this sink in: We’ve already used up a year’s worth of Earth’s resources

Earth Overshoot Day marks yearly point when human consumption outpaces the planet’s ability to replenish resources

You may have missed it but Wednesday, the first day of August, marked Earth Overshoot Day for 2018. What exactly is Earth Overshoot Day? It is the day in any given year that the human community has used more from nature than Earth can renew in the entire year, as calculated by the Global Footprint Network.

Urgent action needed to steer a Hothouse Earth towards a Stabilized Earth

The Earth may be well on its way to an irreversible “hothouse” if people do not take urgent collective action to steer its path to a habitable state, scientists warned. According to a recent study Trajectories of the Earth System in the Anthropocene published by the Proceedings of the National Academy of Sciences of the United States of America (PNAS),even if the target 1.5 degrees C to 2.0 degrees C rise in temperature under the Paris Accord is met, “a domino-like cascade” of biogeophysical feedbacks including the melting of polar ice, forest diebacks, and increased bacterial respiration in the ocean, coupled by annual greenhouse gas emissions “could take the Earth System to even higher temperatures.” “Hothouse” is a term used to describe a “likely uncontrollable and dangerous” condition where global average temperatures could spike by 4 to 5 degrees C and sea levels could rise up to 60 meters higher than today, once the cascade of feedbacks causes the Earth to pass a tipping point.

Jesuit Hakimani Centre improving equity and faireness in water management in Garissa County

Jesuit Hakimani Center has been working with the select Religious Leaders, Civil Society Organizations, and Water Service Providers to improve equity and fairness in water management for communities most affected by the adverse climate in Garissa County. Severe water scarcity in Garissa County is associated with extreme climate variability and deficiencies in water governance.
