Roughly 900 million people lived in low-lying coastal cities and settlements in 2020; a figure that is projected to reach 1 billion by 2050. Is there anything we can do now to reduce sea-level rise and its impacts? Our past actions will already impact sea-levels for thousands of years. But not everything is set in stone. We possess the power to reduce sea-level rise and its impacts over the next century and beyond with our current actions. Some advocate to mitigate the causes, and others to adapt to the consequences. But what do experts say?
Claim:
Sea-level rise is not occurring or showing any impacts, based on photographic evidence.
Human-caused climate change is already accelerating Greenland’s melting and is predicted to continue to accelerate it in the future. In addition to Greenland, most glaciers around the planet are also melting at an accelerating pace. This melt, in addition to the expansion of the ocean as it warms, contributes to elevate sea level at an accelerating rate, threatening coastal cities around the globe.
Thiessen repeated a large number of Lomborg’s claims in his article without fact-checking or verifying these claims by consulting with scientists who actually have expertise on these topics. Unlike scientists, Lomborg writes books and social media posts about a variety of topics, but he does not submit scientific research on these topics to peer-reviewed journals. If Thiessen lacks the scientific knowledge to challenge Lomborg’s claims, he could have done what professional journalists do: reach out to experts to gain insight from them.
Scientists who reviewed the article found that it builds on a collection of misleading and false claims. For instance, Koonin states that “Greenland’s ice sheet isn’t shrinking any more rapidly today than it was eighty years ago”. Contrary to the claim, scientific studies using airborne and satellite altimetry observations show considerable thinning has occurred along the margin of the Greenland ice sheet since 2003.
“This video is misleading in so many ways it’s hard to know where to begin. For a start there’s a repeated assertion that climate “alarmists” won’t enter debate on climate change, but there are many examples of renowned climate scientists such as Gavin Schmidt, Michael Mann and David Karoly entering into debates with climate change denialists. Many scientists have found such debates to be unhelpful as they give the false impression of balance despite there being broad consensus among climate scientists…”
Claim:
Science said in the: 70s, another ice age in 10 years; 80s, acid rain will destroy all crops in 10 years; 90s: the ozone layer will be destroyed in 10 years; 2000’s the ice caps will be gone on 10 years
Claim:
“there has not been a long-term distinctive change in sea level rise rates in the last 120 years”
Claim:
The long-term tide gauge datasets are all in agreement that there is no acceleration
