Water Vapor and Climate Change
Water vapor is estimated to contribute approximately 60% of the Earth’s greenhouse warming effect. However, water vapor itself does not directly control the Earth’s temperature. Instead, its concentration is regulated by temperature. The atmosphere can hold only a limited amount of water vapor, and this capacity depends on the surrounding temperature.
Understanding the Epidemic
The number of drug overdose deaths continues to climb, increasing by nearly 5% from 2018 to 2019. Alarmingly, overdose deaths have quadrupled since 1999, with opioids involved in more than 70% of the 70,630 deaths reported in 2019.
How Security Flaws Can Destroy a Digital Life
In just one hour, an individual’s digital life can be entirely destroyed. It can begin with hackers gaining access to a single account, such as Google, which they can delete. From there, they may compromise a Twitter account to post offensive messages or use an Apple ID to remotely erase all data from devices like iPhones, iPads, and MacBooks.
Policy and Position Statements on Conversion Therapy

Undergraduate Enrollment Trends
Undergraduate enrollment in degree-granting postsecondary institutions grew by 27% between 2000 and 2017, rising from 13.2 million to 16.8 million students. Projections indicate that enrollment will reach 17.2 million by 2028. Between 2000 and 2010, enrollment increased by 37% (13.2 million to 18.1 million students) but declined by 7% from 2010 to 2017 (18.1 million to 16.8 million). The anticipated growth between 2017 and 2028 represents a modest 3% increase.
Data Centres and Data Transmission Networks
Global internet traffic surged by over 40% in 2020, primarily due to the explosion of video streaming, video conferencing, online gaming, and social networking. This surge builds on a decade-long trend of skyrocketing digital service demand. Since 2010, the global number of internet users has doubled, and internet traffic has grown an astonishing 15 times, averaging approximately 30% annual growth.
Arthritis in the United States
In the United States, arthritis affects 21.2% of adults – approximately 53.2 million people. It is a leading cause of work-related disability, with the economic burden of medical expenses and lost earnings reaching $303.5 billion annually as of 2013.
Poor Nutrition
Good nutrition is vital in keeping individuals and future generations healthy. A balanced diet helps children grow and develop appropriately while lowering their risk of chronic illnesses. For adults, eating nutritious foods can lead to a longer life and reduce the likelihood of obesity, heart disease, type 2 diabetes, and certain cancers. It can also help those already managing chronic conditions avoid complications and improve their health.
Understanding the Trends in Public High School Graduation Rates
Public high school graduation rates in the United States have shown consistent improvement over the years, with the adjusted cohort graduation rate (ACGR) reaching an all-time high of 85 percent in the 2016–17 school year. This metric provides critical insights into the educational outcomes of various student groups and helps identify disparities in graduation rates among racial and ethnic populations. Understanding these differences is essential for addressing inequities and improving educational opportunities for all students.
