We plant about 9 billion trees each year. Unfortunately we also clear about 15 billion, leaving a deficit of 6 billion.
A system of using drones is being developed which could plant trees at 10 times the rate of hand planting and at 20 per cent of the cost by firing germinated seeds into the ground.
A pair of operators will be able to plant nearly 100,000 trees per day, so 60 teams could get us to a billion trees a year.
Obviously drones could be used in placed difficult to access manually.
Here are the developers with their gizmo:
Earth Overshoot Day, the date when the world’s resource bank goes into overdraft was marked this year on August 2.
- It’s the point when the amount of natural resources — think trees, fish and water — humanity takes from the Earth reaches the total that can be regenerated over the entire year.
It’s when the amount of carbon emitted reaches the amount the forests and oceans are able to absorb.
If everyone consumed the Earth’s resources like Australians overshoot day would be on March 12.
Scientists aboard a French research ship Tara have been sailing the Pacific, collecting information on coral reefs. Its current expedition will cross 11 time zones and span 100,000 kilometres from Europe to Asia and back again, with the final results collated and published in 2019. However, when they stopped over in Sydney on the way to the Great Barrier Reef the news on the Pacific was shocking according to captain Nicolas De La Brosse:
- “What we’ve seen in really isolated spots like Samoa for example, even though it’s very far away from [developed] countries with pollution, we struggled to find any coral life,” he said.
Mr De La Brosse said nowhere was immune to the effects of global warming.
“It doesn’t matter where you are in the Pacific, coral is starting to bleach.”
In the paper Coral reefs in the Anthropocene:
- the scientists argue saving the world’s reefs requires the acceptance that the reefs of the future will look very different to those of today, and humans may need to help them adapt – perhaps by intervening to increase the proportion of coral species that are tolerant to rising temperatures.
They will simply have to let go the idea of retaining reefs as they are. Yet Terry Hughes from James Cook University, lead author of the paper, has some hope:
“There’s no shortage of people saying reefs will be dead by 2030 or whatever,” Hughes said. “They are going to be different systems with a different mix of species but if we throw the kitchen sink at it and especially deal with climate change then we will have functioning reefs that will sustain and repair themselves and be of some use to people,” he said.
So will we “deal with climate change”? He says that coral reef literature assumes business-as-usual emissions to the end of the century, which would result in global warming of 4, 5 or 6°C. He says that we’ll start to deal seriously with climate change because Florida will go under water.
4. Trump’s Florida “winter White House” in climate change front line
Here’s what Trump’s 126-room resort at Mar-a-Lago would look like with “10- to 12-foot rise in sea level by 2100”, which is increasingly being contemplated by mainstream scientists:
With just two feet, the estate’s western lawns would completely flood, according to the Associated Press.
Here’s what Mar-a-Lago would look like:
Storms and high tides already are a problem in Florida and later this year:
Miami Beach will begin a $US100 flood prevention project, which includes raising roads, installing pumps and water mains, and re-building sewer connections.
Sooner or later the penny will drop. Meanwhile Scientists warn US coral reefs are on course to disappear within decades, including Hawaii.
Volvo announced recently that all of the new cars it produces will be either all-electric or hybrid by 2019. The tipping point when EVs out-compete internal combustion engines is probably the mid-2020s.
Germany is looking to ban the internal combustion engine (ICE) by 2030. They’ve announced they will put about US$1 billion towards electric vehicles with a 4,000-euro discount on electric vehicles and a 3,000-euro discount on hybrids.
Norway is possibly leading the charge, with 30% of current sales being electric. Other countries are following suit, whereas the USA is heading in another direction where Trump is moving to boost oil use by 1.2 billion barrels, kill jobs and cost each car buyer $1650.
That’s according to an IMF study.
- By fuel type, petroleum and coal were the largest recipients of subsidies, the report found, with the China ($1.8 trillion in subsidies), the U.S. ($0.6 trillion) and Russia ($0.3 trillion) the three top subsidizers by nation.
According to the authors’ reading of the data, the European Union (EU) collectively subsidizes less than half the amount that the U.S. does.
The report concludes that by eliminating these subsidies altogether the world could lower its carbon emissions by 21%, reduce air pollution deaths directly attributable to the burning of fossil fuels by 55%, and raise social welfare by 2.2% of global GDP.
