Why climate change and hurricanes are energy security concerns

Never have two hurricanes struck the Gulf of Mexico simultaneously. As it turned out, tropical storm Marco fizzled out, but Laura became the most powerful hurricane to reach Louisiana in 150 years. Hitting perhaps the most important energy complex in America, it is another warning of the growing threat of extreme weather, charged by climate change.

In 2005, Hurricanes Katrina and Rita destroyed 115 mostly older shallow-water oil platforms and damaged many others. Nine months later, production had yet to be fully restored and was 150 million barrels lower over the period.

These storms were unusually strong offshore and, more than Laura, their paths took them over vulnerable infrastructure. Rules have been tightened subsequently to make energy plants more robust.

Hurricane Harvey in 2017 sat over Houston and delivered the most amount of rain in US history. Widespread flooding shut down refineries and led to extensive oil and chemical spills, but with relatively little long-term damage.

By contrast, the oil industry seems to have escaped Hurricane Laura relatively unscathed. The storm interrupted about 1 million barrels per day of crude oil exports, 650,000 customers across the area lost power and a chemical plant suffered a fire and chlorine leak.

Refineries may take some days to restart, but so far, they and offshore platforms appear to have avoided serious effects. If Laura had moved slightly west, it would have hit the refining centre of Port Arthur and probably caused much more damage.

Unlike in 2005, the low-lying Gulf of Mexico coast is now an important centre of liquefied natural gas exports. One project is proposed at Lake Charles itself, the site of the storm’s landfall. The large Sabine Pass and Cameron plants in Louisiana were right in its path and will be the last to re-start operations after damage assessments.

The seven named storms that hit the US before September this year are a record, and hurricane season has yet to reach its peak. Warm water intensifies the rainfall and wind speeds of tropical storms, which gain strength as they swoop over the Gulf of Mexico.

Laura is but another of a recent string of extreme weather. In October, California’s power utility cut off two million customers in a vain attempt to stop its power lines from triggering bushfires. Now, massive fires are spreading through the state again, including the second largest in history.

Possibly the highest temperature recorded worldwide occurred in Death Valley on August 16. The heatwave has led to rolling power cuts that have affected about two million Californians. The state discovered it was short of reserve gas-fired power while neighbouring states in the same boat had no surplus to export. When the sun set and solar generation stopped, the grid operator had to cut off customers to avoid a system collapse.

Between September and January, bushfires in Australia ravaged an area about the size of England. A drought and record-breaking temperatures helped drive the conflagration. The heaviest monsoon rainfall in 89 years of records drenched Karachi last week. China’s Three Gorges dam, the world’s largest, was under threat of overflowing last week because of heavy rainfall.

So far, the world's average temperature is about 1°C above pre-industrial levels. At best, if nations live up to their obligations under the 2015 Paris climate agreement, the average increase will be about 1.5°C. Under current policies, with only weak effort to reduce carbon dioxide emissions from burning fossil fuels and forests, we are in line for an increase of 2.8°C to 3.2°C.

That may not sound like much, but when the world was 6°C colder during the last glacial period that ended 10,000 years ago, ice sheets stretched to London, New York and Chicago, and mammoths roamed as far south as Granada in Spain.

The energy industry will suffer increasingly from extreme weather driven by further rising temperatures. Cyclones rarely strike the Arab world, with Cyclone Gonu, which hit Oman in 2007, being an exception. In 2019, instead of the typical single cyclone, there were five in the Arabian Sea that threatened India, fed by warming seas as those in the Gulf of Mexico.

But Gulf countries and neighbours such as Iraq are more affected by heat waves, which drive an increase in demand for air conditioning at the same time as they lower the efficiency of power plants. Rising sea levels are a further danger to the dense concentration of refineries, petrochemical and LNG plants, storage tanks, oil export terminals and desalination plants along the Gulf and Indian Ocean coasts.

Building resilience to climate change is a must for the energy industry. Its facilities naturally cluster together in coastal areas, but locations need to be screened for climate exposure. Construction standards must be robust enough to withstand higher waves and more violent storms. The forecasting of Laura’s track was exceptionally accurate – such warnings allow timely shutdowns and evacuations – but not all parts of the world are as well-covered as the Gulf of Mexico.

Electricity grids face new vulnerability from the growing share of weather-dependent renewables: hydroelectric, solar and wind. High winds and doldrums alike can shut down wind turbines, often in the high-demand period of a cold and dark northern European winter.

Conversely, sandstorms can sweep in over Middle Eastern solar farms while heatwaves cut nuclear output. But distributing renewables over wider areas, introducing more battery storage to smooth output and expanding international interconnections can give more resilience than a system with single points of failure.

Combatting the weather-related threats of climate change is already a tough challenge for the energy industry. There are no one-time solutions: changes such as rising sea levels will be continuous and relentless. Adapting will be far more disruptive and expensive than avoiding climate change in the first place, but we are unfortunately already past the point of no return.

Keane on …

Liverpool’s Uefa Champions League bid: “They’re great. With the attacking force they have, for me, they’re certainly one of the favourites. You look at the teams left in it - they’re capable of scoring against anybody at any given time. Defensively they’ve been good, so I don’t see any reason why they couldn’t go on and win it.”

Mohamed Salah’s debut campaign at Anfield: “Unbelievable. He’s been phenomenal. You can name the front three, but for him on a personal level, he’s been unreal. He’s been great to watch and hopefully he can continue now until the end of the season - which I’m sure he will, because he’s been in fine form. He’s been incredible this season.”

Zlatan Ibrahimovic’s instant impact at former club LA Galaxy: “Brilliant. It’s been a great start for him and for the club. They were crying out for another big name there. They were lacking that, for the prestige of LA Galaxy. And now they have one of the finest stars. I hope they can go win something this year.”

No more lice

Defining head lice

Pediculus humanus capitis are tiny wingless insects that feed on blood from the human scalp. The adult head louse is up to 3mm long, has six legs, and is tan to greyish-white in colour. The female lives up to four weeks and, once mature, can lay up to 10 eggs per day. These tiny nits firmly attach to the base of the hair shaft, get incubated by body heat and hatch in eight days or so.

Identifying lice

Lice can be identified by itching or a tickling sensation of something moving within the hair. One can confirm that a person has lice by looking closely through the hair and scalp for nits, nymphs or lice. Head lice are most frequently located behind the ears and near the neckline.

Treating lice at home

Head lice must be treated as soon as they are spotted. Start by checking everyone in the family for them, then follow these steps. Remove and wash all clothing and bedding with hot water. Apply medicine according to the label instructions. If some live lice are still found eight to 12 hours after treatment, but are moving more slowly than before, do not re-treat. Comb dead and remaining live lice out of the hair using a fine-toothed comb.
After the initial treatment, check for, comb and remove nits and lice from hair every two to three days. Soak combs and brushes in hot water for 10 minutes.Vacuum the floor and furniture, particularly where the infested person sat or lay.
