Why Were 2023 and 2024 So Hot?

Union of Concerned Scientists

The year 2023 was by far the warmest in Earths recorded history, and perhaps in the past 100,000 years , shattering the previous record set in 2016 by 0.27C (0.49F). According to recent data from NOAAs National Center for Environmental Information, 2024 is likely to be even warmer than 2023. But why were 2023 and 2024 so warm?

Twenty years of blogging in hindsight

Real Climate

It shows the atmospheric concentrations of carbon dioxide (CO 2 ) and tells a story about the carbon cycle, involving Earth’s crust, the atmosphere, land surface, the biosphere, and the oceans. I wrote a post on the IPCC’s summary for policymakers (SPM) on this in 2023, but without much effect.

Why Climate Scientists Are Sounding the Alarm on the Ocean Circulation System AMOC

Union of Concerned Scientists

The potential collapse of the AMOC—which could happen within this century, or be triggered within this century and play out over a longer timeframe—comes as a result of climate change caused by additional heat-trapping emissions like carbon dioxide in the atmosphere. But what exactly would cause the AMOC to collapse?

Arctic Report Card 2024: How Did the Region Fare? Ask the Caribou

Union of Concerned Scientists

For the first time, the Arctic Report Card assessed that the Arctic is faltering as a reliable area for storing carbon away from the atmosphere ( Natalie et al., It was its first failing grade after thousands of years holding onto more carbon than released to the atmosphere. in Arc2024 ). in Arc2024 ).

Opinion: The new renewable revolution: Why carbon dioxide removal will transform the carbon market

A Greener Life

At a moment of unprecedented uncertainty for net zero, biochar-based carbon dioxide removal (CDR) is set to reshape the global carbon market. Driven by integrity concerns around avoided-emissions credits, the value of the global carbon market plunged from $1.87 billion in 2023 to $723 million in 2024.

Trump’s Pick for Energy Secretary, Chris Wright, is Wrong on Purpose. Here are the Facts. 

Union of Concerned Scientists

As NASA explains , over most of the last 800,000 years, until humans started burning fossil fuels, atmospheric CO 2 concentrations basically never went below 180ppm and never went above 280ppm. In the last sixty years, the amount of carbon dioxide in the atmosphere has grown 100 times faster than it did at the close of the last ice age.
