• Australia’s Great Barrier Reef has suffered its third mass bleaching in five years.
  • The Welsh government will plant a national forest that will span the length and breadth of the country.
  • Vehicle emissions drop in March due to COVID-19, but what happens when driving returns?
  • And more…


The Great Barrier Reef in Australia has suffered its third mass bleaching in five years. It’s feared that warmer ocean temperatures, particularly in February, caused the bleaching.

The 1,400-mile Great Barrier Reef system is a Unesco World Heritage site, but is at risk of losing its status due to the widespread bleaching.

Some previously untouched areas have now suffered “moderate or severe bleaching,” according to the Great Barrier Reef Marine Park Authority, which oversees the reef. However, scientists have also found healthy pockets of coral.

Its northern reaches experienced severe bleaching in 2016 and 2017, and as a result, the Great Barrier Reef Marine Park Authority downgraded its long-term outlook to “very poor.”

Chief scientist David Wachenfeld told the BBC:

The reef had only just begun recovering from impacts in 2016 and 2017 and now we have a third event.

Climate change is making the extreme events that drive those impacts both more severe and more frequent, so the damage in an event is worse.

The reef is still a vibrant, dynamic system but overall, with every one of these successive events, the reef is more damaged than previously.

We need to take these events as global calls for the strongest possible action in climate change.

The UN has warned that if temperatures rise by 1.5C, 90% of the world’s corals will die.


The Welsh government, led by Welsh first minister Mark Drakeford, is working to plant a national forest that would run the length and breadth of the country. The forest will connect existing protected woodlands with large-scale tree-planting projects. The purpose of this massive undertaking is to fight climate change.

The forests will also provide habitats for endangered animals such as the red squirrel and the black grouse.

The project has been allocated £5 million, and £10 million will go toward the Glastir Grants, a sustainable land management program.

The Welsh government intends to plant 2,000 hectares (4,900 acres) a year, increasing to 4,000 hectares (10,000 acres) per year as quickly as possible (see page 129 in the low-carbon Wales report).

On March 24, my Electrek colleague Bradley Berman wrote about the huge drop in pollution as a result of social isolation due to the coronavirus. You can read the full article here, but here’s an excerpt:

With the drop in traffic, vehicle emissions have fallen. Satellites, which can detect emissions in the atmosphere linked to cars and trucks, show enormous declines in pollution over major metropolitan areas, including Los Angeles, Seattle, New York, Chicago, and Atlanta. Those are the cities with the most significant restriction on travel due to coronavirus.

Readings from the European Space Agency’s satellites show that over the past six weeks, levels of nitrogen dioxide over cities and industrial areas in Asia and Europe were much lower than in the same period last year.

Nitrogen dioxide, which exacerbates respiratory illnesses, is produced from car engines, power plants, and other industrial processes. NOx originates from the same activities responsible for the world’s carbon emissions, including cars.

Despite the opportunity granted by this respite in vehicle emissions, the US government so far appears unready to support cleaner transportation with enhanced EV incentives. Will the world’s highways quickly return to bumper-to-bumper traffic mostly from internal-combustion vehicles? —Bradley Berman


FridaysForFuture has started weekly live webinars with scientists, journalists, and activists. This week, Greta Thunberg was joined by activist Naomi Klein and World Health Organization climate change and health leader Diarmid Campbell-Lendrum in the first #TalksForFuture.

They discuss coronavirus and what it has to do with climate change. You can watch the webinar here:


Speaking of Greta Thunberg, the young activist announced on Tuesday this week that she and her father, Svante, were “extremely likely” to have had coronavirus. She said her symptoms were mild in her announcement on Instagram (below). Greta and her father isolated themselves in a separate apartment from her sister and mother.

The coronavirus clearly hasn’t stopped her in her climate-crisis activism. Feel better, Greta.

The last two weeks I’ve stayed inside. When I returned from my trip around Central Europe I isolated myself (in a borrowed apartment away from my mother and sister) since the number of cases of COVID-19 (in Germany for instance) were similar to Italy in the beginning. Around ten days ago I started feeling some symptoms, exactly the same time as my father – who traveled with me from Brussels. I was feeling tired, had shivers, a sore throat and coughed. My dad experienced the same symptoms, but much more intense and with a fever. In Sweden you can not test yourself for COVID-19 unless you’re in need of emergent medical treatment. Everyone feeling ill are told to stay at home and isolate themselves. I have therefore not been tested for COVID-19, but it’s extremely likely that I’ve had it, given the combined symptoms and circumstances. Now I’ve basically recovered, but – AND THIS IS THE BOTTOM LINE: I almost didn’t feel ill. My last cold was much worse than this! Had it not been for someone else having the virus simultainously I might not even have suspected anything. Then I would just have thought I was feeling unusually tired with a bit of a cough. And this it what makes it so much more dangerous. Many (especially young people) might not notice any symptoms at all, or very mild symptoms. Then they don’t know they have the virus and can pass it on to people in risk groups. We who don’t belong to a risk group have an enormous responsibility, our actions can be the difference between life and death for many others. Please keep that in mind, follow the advice from experts and your local authorities and #StayAtHome to slow the spread of the virus. And remember to always take care of each other and help those in need. #COVID #flattenthecurve

Margaret Klein Salamon, PhD, is the founding director of The Climate Mobilization. She wrote an op-ed for the Hill on Wednesday, March 25, titled, “We’re in ’emergency mode’ for coronavirus — we can do the same thing for climate.” Here’s an excerpt of how we can take the lessons of this pandemic and apply them to the climate crisis:

A meme has been going around social media reading, ‘Climate change needs coronavirus’s publicist.’

The truth is, everyone who is treating coronavirus as an emergency is its publicist. Humans are social creatures. We look to one another to assess the seriousness of situations and decide whether or not to enter ’emergency mode.’

Societal shifts that would have been considered impossible before the world heard of COVID-19 are now, very quickly, becoming reality.

What we are seeing is the power of ’emergency mode’ — a fundamentally different mode of functioning that individuals and groups can enter during an emergency.

We should talk about the climate emergency every day — and talk about it in personal, not scientific, terms. We should also talk about our fear for the future, our anger, grief and hope.

Both the climate emergency and the coronavirus are global phenomena showing us that our fates are interconnected. We all need to socially distance to keep ourselves and others safe. We all need to talk about the climate emergency, join the climate emergency movement, and initiate a global race to zero emissions.

We can rise and defeat both the coronavirus and the climate emergency. But first, we need to recognize the climate emergency for what it is — an existential threat to all of us.


The excellent magazine Texas Monthly has published an article called, “Is Climate Change Denial Thawing in Texas?”

They write, “Surprising statements by oil industry leaders have grabbed headlines. But the bigger change is under way more quietly, among young Republicans.”

Texas is a fascinating state, as it has a long history of being an oil state — yet now leads the US in generating energy with wind. And it’s also ramping up with solar. And even more interestingly, Texas is a red state, demonstrating that green energy is increasingly bipartisan.

Here’s an excerpt from the article:

There are reasons for hope, and one of them comes from a most unexpected source: young Republicans.

In October, the Texas Politics Project at the University of Texas revealed a stark generational gap among Republicans on the issue of climate. Only 33% of Texas Republicans over 40 said they thought climate change was happening, compared to a whopping 70% of those under 40. Of those young Republicans who believe it is happening, 61% said they’re “very” or “somewhat” worried. Those under-40 Republicans are even more likely to be “very worried” about climate change than independents of all ages.

You can read the whole article here, which was published in the April 2020 issue.
