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.

The Need and Purpose of Nature Markets

13 mins 18 secs

Overview

We are at a critical juncture. Humanity faces the dual challenges of climate change and biodiversity loss, largely due to our current economic systems. Yet, nature itself offers potential remedies. By preserving our natural environments, we can counter up to 37% of climate threats. Nature-based solutions (NbS), harness the power and capabilities of natural ecosystems and biodiversity. In turn, nature markets put a monetary value on nature's indispensable services, thus promoting conservation. With CO2 levels on the rise, endangering biodiversity and ecosystems, the link between the two is evident. Embracing nature can not only mitigate climate issues but also pave the way for a sustainable economic model in harmony with the UN's developmental goals.

Key learning objectives:

  • Understand the interconnected threats of climate change and biodiversity loss

  • Understand nature’s role in mitigating climate change

  • Understand why and how we can transition to a nature-based economy

Summary
What is the link between climate change and biodiversity?

Climate change and biodiversity and intricately connected. Economic systems that prioritise growth have led to increased greenhouse gas concentrations, resulting in trapped heat with results in problems including rising temperatures, ocean acidification, and altered precipitation patterns. These rapid environmental changes stress species and ecosystems, particularly those already impacted by habitat destruction and pollution. Consequently, biodiversity suffers, with the risk of species extinction escalating with every degree of temperature rise. For instance, at 1.5°C warming, 4% of mammals will lose half their habitat, and this percentage grows with increasing temperature.

What role can nature play in mitigating climate change?

Nature is a formidable ally in the fight against climate change. When preserved, ecosystems significantly reduce climate risk. These nature-based solutions (NbS) harness the power of ecosystems to sequester carbon. For example, the oceans, with entities like phytoplankton, seagrasses, and mangroves, capture massive amounts of carbon dioxide annually. Moreover, animals like forest elephants in the Congo Basin and the great whales of the oceans further enhance carbon sequestration through their activities and life cycles. Essentially, by protecting and rejuvenating nature, we tap into its inherent capacity to combat climate change.

Why would we transition to a nature-based economy and use nature-based solutions? 

Transitioning to a nature-based economy and employing nature-based solutions is essential for multiple reasons. A report from the Taskforce on Scaling Voluntary Carbon Markets highlights the need to reduce net CO2 emissions significantly by 2030 to maintain global warming below 1.5°C. Nature-based solutions can achieve up to one-third of these required emissions reductions. They not only sequester carbon but also catalyze a societal shift, fostering markets for environmental services, generating jobs, and unlocking new opportunities. Furthermore, they support various UN’s Sustainable Development Goals, contributing to poverty reduction, inequality alleviation, decent work promotion, and healthier living.
