Six Environmentalists that are Changing the World

Young Champions of the Earth aims to celebrate and support individuals aged between 18 and 30, who have outstanding potential, to create a positive environmental impact. In 2019, seven young people – selected from every global region – will be named Young Champions of the Earth. These winners will receive seed funding, intensive training, and tailored mentorship to bring their big environmental ideas to life.

With applications open for the Young Champion of the Earth Prize United Nations Environment Programme (UNEP) is focusing on six environmentalists that are making a difference.

Responding to Climate Change Deniers with Simple Facts and Logic

With many persons insisting that climate change is not actually taking place, (I’m hoping none of our staff are included in that group, but if you are this article is for you too) this article digitally published by Dork Sahagian on 30 March, 2017, provides five questions and answers that can be used to change the minds of those “climate contrarians” (Sahagian, 2017).

Global Significance of the Changing Freshwater Carbon Cycle – EOS

By Bopaiah A. Biddanda

Freshwater ecosystems constitute a small fraction of our planet but play a disproportionately large and critical role in the global carbon cycle.

As human activities continue to pump carbon into the atmosphere, the backbone of our understanding of the resulting warming is our knowledge of where that carbon is going: into the atmosphere, into the land, and into bodies of water. When it comes to accounting for the carbon absorbed and emitted by water, the role of inland freshwater may appear quite small compared to the vastness of Earth’s oceans. After all, inland lakes, rivers, streams, reservoirs, wetlands, and estuaries cover less than 4% of Earth’s surface [Downing, 2010; Verpoorter et al., 2014].But recent research shows that the roughly 200 million bodies of inland water play a much larger role in the global carbon cycle than their small footprint suggests. Inland streams and rivers move vast amounts of carbon from the land to the ocean, acting as carbon’s busy transit system.

They also play a disproportionately large role in the global carbon cycle through their high rates of carbon respiration and sequestration [Cole et al., 2007; Tranvik et al., 2009].According to recent estimates, the amount of carbon that inland waters emit is comparable to the net amount of carbon absorbed by living organisms on Earth’s land surface and in its oceans. Moreover, bodies of freshwater bury more carbon in sediments each year than the vast ocean floor [Battin et al., 2009; Aufdenkampe et al., 2011].

Nevertheless, there is great uncertainty in these figures, and scant data exist on continental and global scales. The changing climate is putting freshwater ecosystems at great risk: They are warming at an alarming rate, outpacing warming of the atmosphere and oceans. It’s crucial that scientists dedicate more resources to understanding the global impact of the freshwater continuum on the carbon cycle.

Geosystems: An Introduction to Physical Geography (7th ed.) – Robert W. Christopherson

This text introduces persons to the topic of physical geography, integrating the latest research in the field. In every chapter of this textbook one can find information on updated sciences and  URLs to assist with their understanding. At the end of each chapter, one may also find a Critical Thinking section to encourage one to take the next step in the learning process.

This text is highly interactive and visual featuring more than 550 photographs, 125 remote-sensing images from various orbital platforms, 265 maps and more than 400 illustrations to locate and explain concepts.

The main goal of this discipline, i.e. physical geography, is to explain the spatial dimension of Earth’s dynamic systems, such as its energy, air, water, weather, climate, tectonics, landforms, rocks, soils, plants, ecosystems and biomes, using the latest in satellite imagery and statistics.

This document also contains a Student Animation CD, which contains 67 animations of key text figures and concepts, with self-tests, 18 satellite loops and 9 items in a World Map Reference library.

Persons, with a new copy of this document, also have full access to the book’s Student Learning Center, which is a 24/7 study tool with review exercises, web destinations and other features designed to allow persons to maximize their study time.

Although there are newer editions to this text one may still find it highly informative and useful.
