Understanding Negative Latitudes: Mapping Earth’s Southern Hemisphere
Hiking & ActivitiesLatitude and longitude are the two coordinates used to identify any location on the Earth’s surface. Latitude measures the angular distance of a location from the equator, while longitude measures the angular distance of a location from the prime meridian. The equator is the line of 0 degrees latitude that divides the Earth into two
Exploring Earth’s Story: A Historical and Biographical Approach to Geology
Historical AspectsGeology is one of the most fascinating sciences because it allows us to understand the history of the Earth and the processes that have shaped it. However, many people see geology as a dry and technical subject, full of complex equations and jargon. Fortunately, there are many books that present geology in a more accessible
The Impact of Climate Change on Arctic Thermohaline Circulation
Polar & Ice RegionsThe Earth’s climate is changing rapidly as a result of human activities, resulting in a wide range of environmental impacts. One of the most significant changes that is occurring is the alteration of the thermohaline circulation, a global ocean current system that plays a critical role in regulating the Earth’s climate. This article discusses the
Why Does the Ozone Layer Sit at Lower Altitudes in the Northern Hemisphere? Exploring the Earth’s Atmospheric Anomalies
Weather & ForecastsThe ozone layer is a vital component of the Earth’s atmosphere, protecting life on Earth from harmful ultraviolet (UV) radiation from the sun. The ozone layer is found primarily in the stratosphere, a layer of the Earth’s atmosphere that extends from about 10 to 50 kilometers above the Earth’s surface. However, there are some notable
Unraveling the Mystery: A Guide to Understanding VARIANT-IDs in CMIP6 Metadata
General Knowledge & EducationThe Coupled Model Intercomparison Project Phase 6 (CMIP6) is a global effort to coordinate and standardize climate model simulations. CMIP6 includes a large number of climate models and simulations, each of which is identified by a unique identifier called a VARIANT-ID. The VARIANT-ID is an essential part of the CMIP6 metadata and is used to
The True Solar Noon in Perth: Calculating the Time When the Sun is Directly Overhead Using W.A. Time from Southern Cross
Historical AspectsUnderstanding Solar Noon Before we look at the specific question of what time the sun is directly overhead in Perth, it’s important to understand the concept of solar noon. Solar noon is the time when the sun reaches its highest point in the sky for a given location. It’s an important concept for a number
