Chip Grafting to Create a Tree that Grows 40 Kinds of Fruit | National Geographic

Sam Van Aken, an artist and professor at Syracuse University, uses "chip grafting" to create trees that each bear 40 different varieties of stone fruits, or fruits with pits. The grafting process involves slicing a bit of a branch with a bud from a tree of one of the varieties and inserting it into a slit in a branch on the "working tree," then wrapping the wound with tape until it heals and the bud starts to grow into a new branch. Over several years he adds slices of branches from other varieties to the working tree. In the spring the "Tree of 40 Fruit" has blossoms in many hues of pink and purple, and in the summer it begins to bear the fruits in sequence—Van Aken says it's both a work of art and a time line of the varieties' blossoming and fruiting. He's created more than a dozen of the trees that have been planted at sites such as museums around the U.S., which he sees as a way to spread diversity on a small scale.

Is global warming the sun’s fault?

About half the sunlight reaching the surface of the planet is radiated upward in the form of infrared heat, absorbed by the greenhouse gases in the atmosphere, warming the surface of the Earth. This “greenhouse effect” is what makes the planet livable. But now, scientific data shows that the warming of the planet is reaching dangerous levels causing a series of alarming disruptions.

“Satellite measurements taken over the past 30 years show that the sun’s energy output has not increased and that the recent warming observed on Earth cannot be attributed to changes in the sun’s activity,” explained WMO Secretary-General Petteri Taalas. “The rise in temperatures – which are melting ice and heating the oceans – is driven by long-lived greenhouse gases in the atmosphere,” he added.

Independent climate change experts warn that if the current trend in greenhouse gas concentrations continues, we may see temperature increases by 3 °C to 5 °C compared to pre-industrial levels, by the end of the century. WMO’s analysis reveals that the 20 warmest years on record have been in the past 22 years, with the top four in the past four years.

To tackle this, UN Secretary-General António Guterres will be hosting a Climate Summit in New York on 23 September, to galvanize climate action and ambition at the highest levels.

As supporting evidence for the discussions, WMO’s 2018 State of the Climate report will be launched on Thursday 28 March. This report will provide an overview of temperatures, high-impact events, and key indicators of long-term climate change such as increasing carbon dioxide concentrations, Arctic and Antarctic sea ice, sea level rise and ocean acidification. It will be launched alongside a high-level event at the UN General Assembly.

Why the hype around solar energy?

The sun provides us with a valuable source of renewable energy that has the potential to replace fossil fuels like coal or oil, for electricity production, heating, and desalinating water, among other things. Its energy can be harnessed directly with “photovoltaics” or “solar cells”, even in cloudy weather.

According to the International Energy Agency, solar power and other renewable sources have become the technology of choice thanks to falling costs and supportive government policies: by 2040, the share of renewables in electricity generation is expected to rise from 25 per cent today to over 40 per cent.

However, power generation from solar cells is strongly dependent on the weather. Therefore, reliable meteorological forecasts are indispensable for balancing the power grid, and will gain even more importance as the renewable energy sector expands.

==========

Every March 23 marks the anniversary of the 1950 Convention that established the UN World Meteorological Organization (WMO), is the occasion to take stock of the importance of the sun and weather monitoring for the common safety, health and well-being of all living things on the planet.

Through its national meteorological and hydrological services, WMO has been providing expertise, monitoring and forecast services to both harness and protect us from the power of the sun.

“Too little sun impacts our mood and well-being, and increases the risk of Vitamin D deficiency,” said WMO, noting on the other hand that “overexposure to sunlight causes harmful effects on the skin, eyes, and immune system. Experts believe that four out of five cases of skin cancer could be prevented, as UV damage is mostly avoidable.”
