The Relationship Between Extreme Weather Events and Disease Outbreaks

As the pace of climate change accelerates, we’re seeing more extreme weather events occurring all over the globe. Devastating storms, heat waves, deep freezes, and forest fires are just some of the weather events that have been wreaking havoc on communities, causing fatalities, displacement, and property loss. 

The Current State of Air Pollution and How it is Affecting Your Health

Air pollution is as ubiquitous as it is sinister. You can’t see it. Contrary to popular belief, you often can’t detect it without special tools at all. Even air that smells clean can contain dangerous levels of contamination that can result in serious disease and even death after long-term exposure.

Great Barrier Reef has sort of chlamydia

The discovery of chlamydia-like bacteria in corals of the Great Barrier Reef could help scientists understand the coral microbiome and its impact on coral reef health.

Corals are associated with a variety of bacteria, which occur in the surface mucus layer, gastrovascular cavity, skeleton and tissues where they play a critical role in protecting corals against pathogens, cycling nutrients, and producing vitamins and essential amino acids. 

Some tissue-associated bacteria form clusters, termed cell-associated microbial aggregates (CAMAs), which are poorly studied.

DAN Asks Divers To Support the Future of Safe Diving

The campaign aims to raise funds to provide education and safety resources to divers everywhere, enhance emergency response capabilities, and provide forward-looking solutions for keeping divers safe.

"We believe in the power of the dive community coming together to promote a culture of dive safety that will persist through future generations," said Bill Ziefle, DAN President and CEO.

Having healthy lungs is an essential and important part of good diving and never more so since the outbreak of COVID-19. 

In this study which is all about you and your lungs, DDRC wants to focus on Vaping, Asthma, IPO (Immersion Pulmonary Oedema) and COVID-19.

For those of you who have taken part in their studies before you will know that there will also be the usual general health questions and the diving demographic questions too.

Green Island is considered Taiwan’s diving heartland by local divers, and hence, it is an essential rite of passage to do a dive trip there. Now, divers from abroad are discovering the joys of its beautiful underwater realm. Simon Pridmore gives us an inside look.

People commonly say that experienced divers should guard against complacency, but what does that mean? Some associate the idea of complacency with arrogance, carelessness or negligence, and reassure themselves that if character traits such as these do not apply to them, then they do not have to worry about being complacent. Simon Pridmore offers insights into this phenomenon and how to prevent it.

Sustainable shipping program protects endangered whales

Ship strikes are a major threat to whales globally and to the recovery of endangered blue, fin, and humpback whales in California waters. From 2007-2022, observed and documented deaths totalled 52 endangered whales, likely representing a small fraction of the annual total number of ship strikes.

Program

The voluntary incentive program ran from May 1, 2022 through December 15, 2022, with twenty-three shipping companies participating. The 10-knot target allowed ships to travel at an efficient operating load using less fuel and producing less pollution.
