The first scientist to publicise concerns about the implications for humans of burning fossil fuels was Svante Arrhenius, a Swedish scientist.(1)

In 1896, Arrhenius published calculations showing that adding carbon dioxide to the atmosphere could warm the planet (1).

This work built on the research of other 19th-century scientists, such as Joseph Fourier, John Tyndall, and Eunice Newton Foote, who had demonstrated that carbon dioxide and water vapor trapped heat (1)

However, it was Guy Callendar, a British engineer and amateur meteorologist, who in 1938 connected human activities to global warming.

He showed that land temperatures had increased over the previous half-century, and he theorized that people were unwittingly raising Earth’s temperature by burning fossil fuels. His theory became widely known as “the Callendar Effect” (2)

Today, it’s known as global warming

The American Petroleum Institute (API), the powerful fossil fuel trade group, commissioned a report in 1968 that warned of the harmful consequences of burning fossil fuels. (1;2)

This report was delivered privately to the API and was written by scientists at the Stanford Research Institute(1;2;3)

In the 1970s, the National Petroleum Council (NPC), an oil and natural gas advisory committee to the Secretary of Energy, also knew about climate change. (4)

However, it’s important to note that these reports were not necessarily given directly to the American government.

Furthermore, it’s worth mentioning that Exxon, now ExxonMobil and the world’s largest oil and gas company, was aware of climate change as early as 1977, 11 years before it became a public issue. (5)

Despite this knowledge, the company spent decades refusing to publicly acknowledge climate change and even promoting climate misinformation.

You can download all the reports issued by the Intergovernmental Panel on Climate Change (IPCC) from their official website(1)

They provide comprehensive Assessment Reports about knowledge on climate change, its causes, potential impacts, and response options(1).

The IPCC also produces Special Reports, which are an assessment on a specific issue, and Methodology Reports, which provide practical guidelines for the preparation of greenhouse gas inventories.(1)

For specific reports, such as the “Climate Change 2022: Impacts, Adaptation and Vulnerability” report, you can find the final files for download on a dedicated page(2).

This page includes the Summary for Policymakers, Technical Summary, Full report, and individual chapters(2).

The most recent prediction of the Intergovernmental Panel on Climate Change (IPCC) regarding sea level rise was published in the 6th Assessment Report on August 9th, 2021(1)

 The report projects that under a worst-case emissions scenario, a sea level rise of between 0.61 meters (61 cm) and 1.1 meters is now likely by 2100(2)

This projection is 10 centimeters higher than the IPCC’s last big assessment just six years ago(2)

The increase in the projected range is due to a better understanding of how the Antarctic ice sheet is melting

You can access these projections and more detailed information from the IPCC’s official website

 or the NASA Sea Level Projection Tool

Please note that these projections are based on extensive scientific research and are intended to inform policy decisions and climate change mitigation efforts

The 6th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), published on August 9, 2021, does not provide a specific percentage of global ice melting (1)

However, it does state that the rate of ice sheet loss increased by a factor of four between 1992-1999 and 2010-2019(2)

This accelerated ice melt contributes significantly to the observed sea level rise (2)

For more detailed information, you can refer to the full report available on the IPCC’s official website (3)

There are numerous studies and predictions made by global scientists and groups specializing in climate change regarding the amount of ice melt under current human behaviors.

However, it’s important to note that these predictions vary widely due to the complexity of climate systems and the uncertainty of future human behaviors (1,2)

One significant study published in 2021 found that the rate of global ice loss has increased by 65% between 1994 and 2017(1)

In the 1990s, there was an average global ice melt of 0.8 trillion tonnes per year; by 2017, there was an average of 1.3 trillion tonnes per year(1)

This research indicates that the melting of ice sheets is now following the worst-case climate warming scenarios set out by the Intergovernmental Panel on Climate Change(1)

As for when the ice melt would be completed, it’s challenging to provide a precise timeline.

The melting of ice sheets, particularly those in Greenland and Antarctica, is a process that could take centuries, even under high-emission scenarios(2)

The rate of melting can be influenced by a multitude of factors, including atmospheric and ocean temperatures, global greenhouse gas emissions, and natural climate variability(2)

It’s crucial to remember that these predictions are based on current understanding and models, and actual outcomes may vary.

The best way to mitigate the impacts of ice melt and global warming is to reduce greenhouse gas emissions and transition to more sustainable practices(1,2)

Under the worst-case scenario set out by the Intergovernmental Panel on Climate Change (IPCC), not all ice will melt, but a significant amount will.

The rate of global ice loss has increased by 65% between 1994 and 2017 (1,2)

This high melt rate corresponds to the worst-case scenario model for global warming set out by the IPCC(1,3)

However, it’s important to note that the melting of ice sheets, particularly those in Greenland and Antarctica, is a process that could take centuries, even under high-emission scenarios (2)

The rate of melting can be influenced by a multitude of factors, including atmospheric and ocean temperatures, global greenhouse gas emissions, and natural climate variability(2)

In terms of sea level rise, the IPCC estimates a rise of between two [2] and three [3] feet by 2100 if global warming is kept well below two degrees Celsius (3.6 degrees Fahrenheit), or three [3] to five [5] feet if temperatures rise past that temperature.(4)

This is equivalent to a 17-centimetre rise in sea level in just 80 years, putting about 400 million people at risk of annual coastal flooding (3)

These predictions are based on current understanding and models, and actual outcomes may vary.

Yes, scientists have made predictions about the potential sea level rise if all ice sheets on the planet were to melt.

According to NASA, if all glaciers and ice sheets melted, global sea level would rise by more than 195 feet (60 meters)(1)

However, it’s important to note that this is a theoretical scenario.

The complete melting of all ice sheets is not expected to occur withinthe foreseeable future, even under the most extreme climate change scenarios (1,2,3)

The melting process is influenced by a multitude of factors and could take many centuries or even millennia (1,2,3)

There are indeed studies that have attempted to calculate the economic impact of sea level rise due to melting ice sheets, but the exact figures can vary widely due to the complexity of the issue (1)

The economic damage would be enormous, affecting coastal cities, agriculture, fisheries, and other key sectors(1)

However, it’s important to note that these estimates are fraught with uncertainty.

The actual economic impact could be much higher or lower depending on a range of factors, including the rate of ice melt, the effectiveness of adaptation measures, changes in economic growth, population movements, and many others(1)

Unfortunately, I couldn’t find a specific dollar figure for the total global economic damage if all ice sheets were to melt.

This is likely because such a scenario is considered extremely unlikely within this century, and the economic conditions of future centuries are too uncertain for accurate predictions(1)

For more detailed information, you may want to look at the research literature on the economic impacts of sea level rise(1)

Please note that while these studies provide valuable insights, they should be used responsibly given the uncertainties involved.
