Environmental and climate denialism

Environmental or climate denialism has been around for decades, simmering as an undercurrent, until picked up by proponents such as Bjørn Lomborg1 and Donald Trump. These individuals often denied the science behind environmental and climate issues, or argued minutia and side-tracking discussions to irrelevant distractions.
Environmental denialism is a form of scepticism or denial that challenges the scientific understanding of environmental issues, particularly climate change. It can involve outright rejection of the science, or questioning its extent, severity, or human influence.
Some have argued that environmental denialism was originally “developed” by certain business interests who were looking for a response to such environmental and shareholder group initiatives such as “greenwash”, ESG (Environment, Social and Governance), Sustainable Consumption and Production, Carbon Reporting and Monitoring, Sustainable Packaging, and Low-Carbon Transport. All of which involved some short- and medium-term increases in costs (mostly capital and set-up costs) and reduced profits.
Greenwashing is a deceptive marketing tactic where a company portrays itself or its products as more environmentally friendly than they truly are. It involves making false or misleading claims about a company’s environmental impact to deceive consumers and gain a positive public image.
Often, the focus is on the cause or consequences of, for example, climate change, rather than exploring ways to mitigate the negative impacts. Climate change in South Africa has manifested itself, not so much in increased rainfall, but rather in the increased intensity of storms. This means that instead of receiving 50mm of soft, soaking rain over a 24-hour period, the same 50mm of rain falls in a 20-minute intense storm, resulting in less soil infiltration and more flooding. In such situations, we should focus on mitigating the occurrences, such as by enhancing stormwater protection, improving storage facilities, and upgrading stormwater management systems, rather than debating endlessly whether the cause is natural or Human-Induced.
Environmental and Climate Denial Quotes by Donald Trump
“They never talk about the environment anymore. You know why? […] It’s one of the great scams of all time.”
“The concept of global warming was created by and for the Chinese in order to make US manufacturing non-competitive.”
“It’s [sea level rise] going to create more oceanfront property.”
Environmental and Climate Denial Quotes by Bjørn Lomborg
“Global warming is real – it is man-made and it is an important problem. But it is not the end of the world.”
“Just because there is a problem doesn’t mean that we have to solve it, if the cure is going to be more expensive than the original ailment.”
“On average, global warming is not going to harm the developing world.”

In South Africa, where we cherish freedom of speech, we should rather focus our efforts on supporting “green initiatives” and practices, and adopt sound environmental and climate policies and practices. We should challenge our elected representatives to adopt and implement greater use of solar energy (solar geysers are a no-brainer in our country with between 300 and 320 days of sun per year), resource optimisation (reduce, re-use, recycle), and water and energy conservation. It is also critical that the Electorate hold their elected representatives accountable for their actions, policies and promises.
“Accountability breeds response-ability.”

Notes
Bjørn Lomborg1
Bjørn Lomborg, author of “The Sceptical Environmentalist”, has established himself as the world’s leading ‘lukewarmer’. He does not reject the basic physics of the greenhouse effect, but he denies that climate change poses a significant threat to the planet.
