Visualized: How Snowflakes are Formed

The Art of Snow

If you look at snow up close, you will probably notice that it is made up of thousands of tiny flakes with beautifully complex designs.

These snowflakes are actually ice crystals. They form in our atmosphere, high in the clouds, and transform along their journey to Earth thanks to different factors and forces.

We look at how snowflakes are formed, and what atmospheric conditions contribute to the beautiful intricacies we’ve come to know them for.

How to Build a Snowflake

The designs of snowflakes are actually products of a crystallization process that is controlled by the atmosphere.

Water vapor in the atmosphere latches onto a free-floating speck of pollen or dust and acts as a nucleator. This means that it can begin to add on (ie. nucleate) more water molecules and grow in size. When this happens at cold temperatures, water also freezes and crystallizes.

Despite the many unique styles of snowflakes, they all crystallize in the exact same shape—a hexagon. The reason for this has to do with how water behaves at the chemical level. At room temperature, water molecules flow randomly around each other, forming and breaking bonds endlessly.

When temperatures cool, however, they begin to lose kinetic energy and form more stable bonds. By 0°C, they reorient themselves into an energetically-efficient position, which happens to be a rigid, hexagonal configuration. This is frozen water, or ice.

All snowflakes nucleate and crystallize this way. As more water molecules nucleate to the infant (Read more...)

ESG Data: The Four Motivations Driving Usage

Data is key to the environmental, social, and governance (ESG) revolution. Access to granular ESG data can help boost transparency for market participants. Unfortunately, 63% of U.S. and European asset managers say a lack of quantitative data inhibits their ESG implementation.

Being clear on the potential application of this data is equally important.

  • Investors and banks can use ESG data for risk assessment, to spot opportunities, and to push companies for change.
  • Companies can publish their own ESG data, quantify progress on their ESG goals, and use data to inform decisions.
  • Policymakers can use ESG data to inform regulatory frameworks and measure policy effectiveness.

This graphic from ICE, the second in a three part series on the ESG toolkit, explores four primary motivations of ESG data users.

1. Right Thing

The objective: Having a positive social or environmental impact.

For investors, this can involve screening out companies that conflict with their values and selecting companies that align with their ESG objectives.

As another example, it can involve comparing the social impact of municipal bonds. One way investors can measure social impact is through scores that quantify the potential socioeconomic need of an area, using metrics like poverty and education levels. Here are the social impact scores for three actual municipal bonds issued in Florida.

How Environmental Markets are Advancing Net Zero

How Environmental Markets Advance Net Zero

In 2021, roughly 20% of global carbon emissions were covered by carbon pricing mechanisms.

Meanwhile, the global price of carbon increased 91%, bolstered by government, corporate, and investor demand. This puts traditional fuel sources at a disadvantage, instead building the investment case for renewables.

This infographic from ICE, the first in a three part series on the ESG toolkit, explores how environmental markets work and their role in the fight against climate change.

What are Environmental Markets?

First, meeting a goal of net zero carbon emissions involves limiting the use of the world’s finite carbon budget to meet a 1.5°C pathway.

Achieving net zero requires us to:

  • Change how we utilize energy and transition to less carbon-intensive fuels
  • Put a value on the conservation of nature or “natural capital” and carbon sinks, which accumulate and store carbon

Environmental markets facilitate the pathway to net zero by valuing externalities, such as placing a cost on pollution and placing a price on carbon storage. This helps balance the carbon cycle to manage the carbon budget in the most cost-effective manner.

What Is the Carbon Budget?

To keep temperatures 1.5°C above pre-industrial levels, we have just 420 gigatonnes (Gt) of CO₂ remaining in the global carbon budget. At current rates, this remaining carbon budget is projected to be consumed by 2030 if no reductions are made.
