U.S. Arctic Environmental Policy and Career Opportunities

U.S. Arctic Environmental Policy and Career Opportunities
U.S. Arctic environmental policy focuses on sustainability, scientific research, and international cooperation through the Arctic Council, where eight nations collaborate on environmental protection. The melting Arctic ice cap opens new shipping routes and resource extraction opportunities while raising concerns about ecosystem impacts. For environmental science students, Arctic policy represents a critical intersection of climate science,…

What Environmental Data Tells Us About Greenland’s Viking Collapse

What Environmental Data Tells Us About Greenland’s Viking Collapse
Environmental data—including pollen analysis, ice core isotopes, and soil studies—reveals that Greenland's Norse colonies persisted for several centuries during and after the Medieval Warm Period but collapsed rapidly as conditions cooled in the early 14th century. Limited adaptation to changing conditions and cultural pressures to maintain European farming traditions increased vulnerability when temperatures dropped, illustrating…

Geospatial Technology: An Introduction and Overview

Geospatial Technology: An Introduction and Overview
Geospatial technology combines Geographic Information Systems (GIS), remote sensing, and GPS to analyze spatial relationships and environmental patterns. These tools have become essential in environmental science careers, enabling scientists to track climate change, monitor wildlife populations, assess ecosystem health, and plan conservation strategies. Environmental scientists with geospatial skills earn a median salary of $80,060 nationally,…

Ornithology: The Scientific Study of Birds

Ornithology: The Scientific Study of Birds
Ornithology is the scientific study of birds — their biology, behavior, ecology, evolution, and conservation. Most ornithologists enter the field through a degree in zoology or wildlife biology, with research careers typically requiring a master's or PhD. Birds are among the most valuable indicators of environmental health, making ornithology central to modern conservation science. Birds…

Natural Gas 101: Pros, Cons & Career Guide

Natural Gas 101: Pros, Cons & Career Guide
Natural gas is a fossil fuel primarily composed of methane, formed over millions of years from decayed organic matter. It supplies approximately 22% of global energy needs for heating, electricity generation, and industrial processes. While natural gas burns cleaner than coal or oil—producing 50% less carbon dioxide—its extraction and use raise environmental concerns including methane…

Hydroelectric Power: How It Works, Pros & Cons, and Careers

Hydroelectric Power: How It Works, Pros & Cons, and Careers
Hydroelectric power harnesses the kinetic energy of moving water to generate electricity, making it the world's most widely used renewable energy source. It's clean, cost-effective, and capable of producing power at scales ranging from a few kilowatts to over 20 gigawatts. It currently generates roughly 19% of the world's electricity, with careers in the field…

What is NEPA? Introduction to U.S. Environmental Policy

What is NEPA? Introduction to U.S. Environmental Policy
The National Environmental Policy Act (NEPA), signed into law on January 1, 1970, requires all federal agencies to assess environmental impacts before taking major actions. NEPA established three types of review documents (EIS, EA, and CE), created the Council on Environmental Quality, and gave citizens a voice in federal decision-making through required public participation. The…

Hydraulic Fracturing: Health Risks, Regulations & Career Impact

Hydraulic Fracturing: Health Risks, Regulations & Career Impact
Hydraulic fracturing extracts natural gas and oil from deep shale rock by drilling vertically, then horizontally, and pumping high-pressure fluid to fracture the formations. Now producing 67–79% of US natural gas and 50% of crude oil, the technology has transformed American energy independence. However, peer-reviewed research increasingly links fracking operations to elevated childhood cancer rates,…

Aerial Photography in Environmental Science: A Complete Guide

Aerial Photography in Environmental Science: A Complete Guide
Aerial photography involves capturing images of the Earth's surface from aircraft, drones, or other elevated platforms. It's used across environmental science—from tracking climate change and mapping vegetation to archaeological surveys and urban planning. Images are taken either obliquely (at an angle) or vertically (straight down), with each method serving different research needs. When paired with…

Understanding Drought in the United States: Types, History, and Impact

Understanding Drought in the United States: Types, History, and Impact
Drought is a temporary period when water availability falls below normal levels for a region, affecting humans, agriculture, and ecosystems. The United States experiences four types of drought—meteorological, agricultural, hydrological, and socioeconomic—each triggered by different conditions and impacting different sectors. While cyclical in nature, droughts have grown more intense due to climate change and increasing…
