The last migration of the monarch butterflies? | Environmental Action

In the 1980s, about 4.5 million monarch butterflies wintered in California. This year? There were only about 30,000.
I grew up in the Bay Area in the 1990s—monarchs were an important part of my childhood. I want them to be a part of my children’s memories, too.
Seeing a monarch butterfly takes me right back to being a child. Monarchs flew to California every winter season.

I took many trips to monarch sanctuaries in Santa Cruz and Monterey with my classmates, where we learned about their lifecycle, epic migration, and even why they have their color (to warn potential predators that they are dangerous!).
But these butterflies are vanishing. We need all hands on deck if we’re going to save them. Alarmingly, the population of monarch butterflies that spent the winter in California was less than 0.5 percent of its historical size—and this year’s population was down by roughly 86 percent compared to 2017.

Tesla YouTuber Bjørn Nyland breaks 24-hour electric car distance record — 2,781km - Electrek

A common refrain about electric cars is that they’re fine for city driving but can’t do road trips.  This has been disproven many times, and Tesla owners in particular have an easy time on road trips due to Tesla’s excellent Supercharger network.
But today we’ve seen yet another reason not to worry about the capability to take EVs on long trips, as Bjørn Nyland has managed to drive 2,781km (1,728mi) in 24 hours in a Tesla Model 3 Long Range AWD.  Nyland set this record on IONITY quick chargers in Germany because currently, that network is significantly faster than Tesla’s Superchargers.
The previous record was 2,644km, set last year in a Model 3 by German Horst Lüning. Lüning previously held the record before that with 2,424km in a Model S.
Nyland wanted to emphasize that this record could be done in “realistic” conditions, so there was no closed course and common road rules were followed.  The record was set in Germany, on the Autobahn, and was done at high speeds, around 170km/h (105mph) much of the time.

Are parts of India becoming too hot for humans?

India, the Arabian peninsula and gulf states, SW USA all will become unbearable- and then it will get worse...

Intense heat waves have killed more than 100 people in India this summer and are predicted to worsen in coming years, creating a possible humanitarian crisis as large parts of the country potentially become too hot to be inhabitable.
Heat waves in India usually take place between March and July and abate once the monsoon rains arrive. But in recent years these hot spells have become more intense, more frequent and longer.

India is among the countries expected to be worst affected by the impacts of climate crisis, according to the Intergovernmental Panel on Climate Change (IPCC).
Experts at the Massachusetts Institute of Technology (MIT) say that even if the world succeeds in cutting carbon emissions, limiting the predicted rise in average global temperatures, parts of India will become so hot they will test the limits of human survivability.

"The future of heat waves is looking worse even with significant mitigation of climate change, and much worse without mitigation," said Elfatih Eltahir, a professor of hydrology and climate at MIT.

You could be ingesting a teaspoon of microplastic every week, study finds - ABC News (Australian Broadcasting Corporation)

A new study has found that the global average of microplastic ingestion could be as high as five grams a week per person, which is the equivalent of eating a teaspoon of plastic — or a credit card — every week.
The study was commissioned by the World Wide Fund for Nature (WWF) and carried out by the microplastics research team at Australia's University of Newcastle.
It collated the findings of 50 international research papers in an attempt to provide an accurate calculation of ingestion rates.

Alaska sees record temperatures in heatwave

The US state of Alaska, part of which lies inside the Arctic Circle, is sweltering under a heatwave, with record temperatures recorded in several areas, including its largest city.
Temperatures reached 90F (32C) in Anchorage on Thursday, shattering the city's previous record of 85F.
Several other places in southern Alaska also set all-time or daily records.
Experts say the unusual weather has been caused by a "heat dome" over the southern part of the state.

The high pressure system is expected to move north next week.

Climate change: Trees 'most effective solution' for warming - BBC News

Researchers say an area the size of the US is available for planting trees around the world, and this could have a dramatic impact on climate change.
The study shows that the space available for trees is far greater than previously thought, and would reduce CO2 in the atmosphere by 25%.
The authors say that this is the most effective climate change solution available to the world right now.

CO2 emissions are set to exceed 1.5 degrees of global warming | Science News

Current and planned energy infrastructure could emit around 850 gigatons of the greenhouse gas.
A new study shows just how hard it may be to limit global warming to 1.5 degrees Celsius over preindustrial times.
The world’s existing power plants, industrial equipment, vehicles and other CO₂-emitters are on track to pump out enough carbon dioxide to blow past that target by midcentury, researchers report July 1 in Nature.  Add in future power plants that are already planned, permitted or under construction, and we could emit enough by 2033 to raise average global atmospheric temperatures by 1.5 degrees, the researchers say. 
If we want to limit warming to 1.5 degrees, then “we cannot invest more in fossil fuel power or infrastructure,” says Thorsten Mauritsen, a physical climate scientist at Stockholm University who was not involved with the work. “Everything we do from now has to change direction and not use fossil fuels.”
In the 2015 Paris Agreement on climate change, nearly all the world’s nations agreed to try to reduce greenhouse gas emissions enough to limit warming to “well below” 2 degrees by 2100 (SN: 1/9/16, p. 6). The United States has said it would pull out of the agreement (SN Online: 6/1/17), though the exit wouldn’t be complete until 2020.
Still, calls have increased since 2015 for the more ambitious goal of keeping warming to 1.5 degrees. That would mean fewer heat waves, spells of extreme weather and species extinctions (10/27/18, p.7).

COMMITTED  Carbon dioxide emissions from the fossil fuel infrastructure that’s already built will probably push us past 1.5 degrees Celsius of global warming, according to a new study.
