Excerpts;

Further steps have been taken to clean up beaches and seas in 2019 – but much more needs to be done.

From having little impact on the climate just 20 years ago, the production and disposal of plastic now uses nearly 14% of all the world’s oil and gas. Plastic production is expected to grow to 20% by 2050 by which time the industry’s climate emissions could rise to 2.75bn tonnes a year and plastic could be driving half of all oil demand growth…

Plastic Pollution: “When The Mermaids Cry: The Great Plastic Tide,” Coastal Care
Plastic is versatile, lightweight, flexible, moisture resistant, strong, and relatively inexpensive. Those are the attractive qualities that lead us, around the world, to such a voracious appetite and over-consumption of plastic goods. However, durable and very slow to degrade, plastic materials that are used in the production of so many products all, ultimately, become waste with staying power. Our tremendous attraction to plastic, coupled with an undeniable behavioral propensity of increasingly over-consuming, discarding, littering and thus polluting, has become a combination of lethal nature…

Excerpts;

A storm is certainly brewing. The science is clear on that. The question now is how we face it.

Unless we focus on shared solutions, violent storms and devastating blazes could be the least of the world’s troubles. Civilisation itself will be at risk…

Excerpts;

In the South Pacific Ocean east of New Zealand, satellite imagery shows a massive area of ocean water at well-above-average temperatures.

The water in the area is about 5 degrees Celsius (about 9 degrees Fahrenheit) “warmer than average for the latitude and time of year,” said James Renwick, a professor and head of the School of Geography, Environment and Earth Sciences at Victoria University in Wellington, New Zealand…

Excerpts;

A global effort to transition to 100 percent renewable energy by 2050 would cost nations $73 trillion upfront — but the expense will pay for itself in under seven years, according to a new report from researchers at Stanford University.

The study also found that the shift to a zero-carbon global economy would create 28.6 million more full-time jobs than if nations continue their current reliance on fossil fuels…

Excerpts;

Global climate change is an obvious fact and we are already in the midst of it. The time for action is now. In two decades, in the opinion of many climatologists, it will be too late to prevent catastrophic global damage…

Excerpts;

Both Dorian and Lorenzo, which became the strongest hurricane to develop so far northeast in the Atlantic, attained Category 5 strength. The storms brought the count of Category 5s in the Atlantic since 2016 up to six, and marked the fourth year in a row with at least one Category 5, the longest stretch on record.

The historic intensity of both Dorian and Lorenzo, exhibited influences consistent with warming ocean waters and climate change…

Gulf of Mexico coral reefs to protect from storm surge in the future — But will they?

Excerpts;

Coral reefs support 25 percent of all marine life around the globe. Those in the Gulf of Mexico, along the coasts of Louisiana, Florida, Texas and Mexico serve as important barriers to storm surge, lessening the impact of dangerous hurricanes.

A team of researchers used coupled climate model simulations as well as studies of fossil corals to describe how climate change will impact reefs in the Gulf of Mexico in the not-so-distant future, including a realistic snapshot of years 2080-2100…
