The Science of Climate Change
Climate change is no longer a distant threat or just a possibility, it is now a reality for all of us. In this pathway, Kevin Trenberth, a renowned climatologist, delves into the science behind climate change. He first introduces the climate system, its main components and forces.
Tackling the Plastic Crisis
Plastic pollution is by far the biggest threat to our oceans and this remains an incredibly tough problem to solve. Plastic credits could potentially serve as one of the much needed solutions for this crisis.

The Scale of the Net Zero Challenge
The price of meeting net zero is estimated to be between $100-150 trillion over the next 30 years. Regardless of this cost, we need to reach net zero before climate change does irreversible damage to the environment and the economy.
ESG, Sustainability and Impact Jargon Buster
ESG, sustainability, impact… they all just mean green, right? Not quite. Despite being used often interchangeably, there are distinct differences between these terms.

Introduction to Measuring Biodiversity Loss
Samuel Temidayo Osinubi
Avian ecologist
Climate change is affecting species, ecosystems and biodiversity on an unprecedented level. The sustainability of these resources requires assessment of the resources. That’s where classifications come into play. Join Samuel Temidayo Osinubi as he explores this in depth.

Introduction to Measuring Biodiversity Loss
9 mins 57 secs
The International Union for Conservation of Nature (IUCN) is the global authority on the status of the natural world. Principally, the IUCN monitors biodiversity at species and ecosystem levels, through the: Red List of Threatened Species and Red List of Ecosystems. Both lists are based on a scientific system of data, verification and analysis, such as population size and geographic range (Red List of Threatened Species) or declining distribution and rate of abiotic degradation (Red List of Ecosystems). Species range can also vary spatially - either through expansion, shift or reduction.
Key learning objectives:
Understand the red list of species and ecosystems
Outline how species ranges can change

What is the IUCN?
The International Union for Conservation of Nature (IUCN) is the global authority on the status of the natural world. Principally, the IUCN monitors biodiversity at species and ecosystem levels, through the:
- Red List of Threatened Species
- Red List of Ecosystems
What does the IUCN Red List of Threatened Species measure?
The Red List is based on scientific system of data, verification and analysis including:
- Population size
- Geographic range
- Rate of population decline or growth
- Degree of population
- Distribution fragmentation
Species are classified into nine categories: not evaluated, data deficient, least concern, near threatened, vulnerable, endangered, critically endangered, extinct in the wild, and extinct.
What does the IUCN Red List of Ecosystems measure?
The Red List is based on scientific system of data, verification and analysis including:
- Declining distribution
- Restricted distribution
- Rate and extent of abiotic degradation
- Rate and extent of disruption of biotic interactions
- Statistical model with quantitative estimates on the risk of ecosystem collapse
Ecosystems are classified into eight categories: not evaluated, data deficient, least concern, near threatened, vulnerable, endangered, critically endangered, and collapsed.
How can species range change?
The trend of change in the geographic range of a species can be explored in space and time. A change in range could result from several factors that can be biotic, abiotic or an interaction of both. Biotic factors can include the life history of the species (these are traits or patterns of survival and reproduction observed in a particular species that comprise fecundity, age at sexual maturity, maximum body size and lifespan). Other biotic factors are predator and prey relationships, pest and diseases, and competition.
Abiotic factors can influence a species range of tolerance.
What constitutes a spatial change in species range?
- Expansion is the colonisation of areas outside historic ranges of a species, while maintaining historic ranges.
- Shift is the colonisation of areas outside historic ranges with an extinction from parts or all historic ranges.
- Reduction or contraction of a species range is an extinction from parts of the species historic range.

Introduction to Natural Capital and Biodiversity
In this video, James introduces the five key questions that must be considered when exploring natural capital. He defines what natural capital is, why it is important and what implications the decline of natural capital is already having and will have in the near future. He delves into why natural capital is currently misvalued and finally, what we can do to move to a more nature positive economy.

Why Our Oceans Matter
The ocean is big, blue and invaluable. If it was a country it would have the largest economy in the world - and we’ve only managed to explore 5% of it. Unfortunately, this is all at risk from human activity. Join Vincent Kneefel in this introductory video, as he explores the importance of the ocean to livelihoods and the meaning of the blue economy.

Is It Too Late to Save the Ocean?
Over 40% of the ocean has already been severely affected by 5 key threats - and this will have disastrous long-term consequences. How we decide act in the next 10 years will be vitally important. Join Vincent Kneefel in this video as he outlines what these key threats are and how they are affecting our oceans.

Plastics and the Circular Economy
Plastic is great for packing your lunch and paying for products. It’s not so great for marine life. In fact, 11 million tons of plastic ends up in our ocean with 100,000 marine mammals dying annually as a result. How did we get here? Join Vincent Kneefel as he explores why plastics are harmful and how we can reduce the amount in circulation.

Nature-based Solutions Case Study
Nature-based solutions are one of the most important tools available to tackle the climate crisis. There is a distinct link between a lack of financing that makes these solutions particularly difficult to scale. In this video we will explore a case study of a successful nature-based solution in central Mexico.
