WHATS IN THIS BLOG: • The situation is worse than we thought. • Between 70 and 90% of coral reefs expected to die off, including Australia’s Great Barrier Reef. • Individuals can do something about it. • Being aware of what we eat, where it comes from, how we travel, how we heat our homes, can impact energy use and greenhouse gas emissions. • Drastic action is required but will require global political engagement.

NEW IPCC REPORT OUT IN OCTOBER 2018. I live in the southwest USA. Seeing more pine trees killed by pine-bark beetles is sad. The huge numbers of wildfires in the west got to me this past summer. Hearing about the terrible droughts now in Australia is dwpressing.… More “Climate Change: Part 5. New IPCC report – scary or not?”

WHATS IN THIS BLOG: • Rising sea levels. • Severe heat waves. • Political instability. • Deterioration of ocean life.

This is part of a series on climate change. Information in this article is taken from the book Climate of Hope by Bloomberg and Pope. See pic of book cover below.

CLIMATE CHANGE AND FIRES. Hurricanes Harvey and Irma were in all the news in my last two blogs on this subject (click HERE and HERE). Soon after, California was beset by the Napa Valley fires – the most destructive in the state’s history. The numbers are 41 people dead, 220,000 acres burned, and 2,800 homes burned.

In the following sections, we have excerpted from Climate of Hope.

 

RISING SEA LEVELS.… More “Climate changes: Part 3. The Stakes are high”

WHATS IN THIS BLOG: • Climate change versus hurricanes and forest fires. • A new book on climate change. • What causes climate change? • Can we predict climate change effects? • Should the USA buy insurance against climate change?

Just to clarify: this blog and (I hope) the next one will center on Science and Energy.

CLIMATE CHANGE IS CONTROVERSIAL, but recent events in September of 2017 force us to think about it once again. I’m referring to hurricane Harvey which went through Houston and hurricane Irma which hit Florida, both causing billions of dollars of damage within the past month.

BUT I’M ALSO REFERRING TO FOREST FIRES which are raging across the western part of the USA. Until this week there were about 40 of them.… More “Climate change: Part 1”

Wind energy and fossil energy – This is a long blog. But richly informative if you want to know more about the debates on global warming, fossil energy, and renewables. It’s also based on data and facts (real facts). I have tried to strike a balanced approach. This blog is written for the layman, as well as the expert. The write up finishes with Texas. The largest oil and wind-energy producer in the USA.

WHATS IN THIS BLOG: • The shale revolution. • Dependence on foreign energy. • Manufacturing renaissance. • Prolonged use of fossil fuels. • Urgency of global warming. • Greenhouse gas emissions – main sources. • Reducing greenhouse gases. • Renewables and fossil fuels in Texas.

THE SHALE REVOLUTION.… More “Wind energy and fossil energy: can they co-exist?”

Definitions: Fracking is hydraulic fracturing, a process where water (or similar liquid) is pumped down a well under high pressure. It is a proven technology in use for over 60 years. The pressure splits the rock like an axe splits a log, and creates fractures (cracks) in the rock containing the oil or gas.

The fractures grow in length and height, and act as conduits to allow the oil or gas faster access to the well. This means a higher production rate. The fractures are a bit like those you see in the sidewalk or roadway. They’re long but not very wide. Typical fracture widths are less than half an inch, and usually much smaller.

The revolution that is called shale gas or shale oil has been successful because many frac treatments are pumped one at a time along the length of a horizontal well.… More “Some Truths about Fracking, Part 1”
