NEW PAPER: All Excess Emissions must be Removed

Marginal Carbon • 138 implied HN points • 14 Oct 24
🌞 Climate & Environment Global Warming
  1. Countries with a history of high carbon emissions have run out of their fair share of carbon budget. They keep adding to their carbon debt with every new emission.
  2. To keep temperatures safe, all emissions beyond what's allowed must be removed. This means we need to deal with past, present, and future excess emissions.
  3. While cutting emissions is the main goal, some emissions are better dealt with using carbon removal strategies, called 'CDR-optimal' emissions.

The Real Enemy

Dana Blankenhorn: Facing the Future • 79 implied HN points • 11 Oct 24
🌞 Climate & Environment Global Warming
  1. Nationalism is a big problem for addressing climate change. It stops countries from working together and tackling the urgent issue of global warming.
  2. People are often focused on their own countries and ignore the need for cooperation. This 'mine' vs 'ours' mindset won’t help solve climate issues.
  3. For real change to happen, everyone needs to unite and fight against climate change together. Without that, the planet will keep suffering.

Whales Die, While Officials, Media, and Environmentalists Lie

RESCUE with Michael Capuzzo • 7567 implied HN points • 28 Jun 23
🌞 Climate & Environment Global Warming
  1. Whales are dying along the East Coast due to offshore wind turbines and oil & gas drilling, raising concerns about environmental impacts.
  2. There is uncertainty and disagreement among experts and agencies about the connection between offshore wind activities and whale deaths.
  3. Offshore wind projects may have limited impact on global emissions and climate change, but they are still considered integral for state plans.

Has the Rate of Global Warming More Than Doubled?

God's Spies by Thomas Neuburger • 160 implied HN points • 11 Feb 26
🌞 Climate & Environment Global Warming
  1. Global warming has clearly accelerated since about 2015, with recent warming rates more than double the long-term 1970–2010 trend.
  2. If the next La Niña low is higher than past El Niño highs, that would confirm the faster warming and make 2°C of global warming likely in the 2030s instead of midcentury.
  3. The practical response is to plan and prepare to adapt to greater climate risks while still living well and focusing on what matters in daily life.

Power Down Blunder

Breaking the Global Warming Gridlock

The Honest Broker Newsletter • 1540 implied HN points • 15 Jul 25
🌞 Climate & Environment Global Warming
  1. Focusing only on reducing greenhouse gas emissions isn't enough to tackle climate issues. We need to look at other ways to manage and adapt to environmental changes.
  2. A clear division in how climate change is viewed causes political gridlock. Different groups have opposing views which makes finding common ground hard.
  3. Helping people adapt to the effects of climate change can actually support efforts to reduce emissions. We should aim to do both, rather than just one or the other.

Will oil and gas consumption keep rising through 2050?

Sustainability by numbers • 439 implied HN points • 17 Nov 25
🌞 Climate & Environment Global Warming
  1. The IEA's Current Policies Scenario is not a prediction of future events, but a 'what if' model based on existing policies. This means it shouldn't be taken as a definite forecast.
  2. Electric vehicle sales are expected to increase mainly in Europe and China, while the rest of the world might see stagnant growth due to lack of supportive policies and charging infrastructure.
  3. Solar energy deployment is expected to stall at 2024 levels for a long time, but this assumption might be overly conservative given that past projections have often underestimated actual growth.

Two Points on Climate Change

David Friedman’s Substack • 350 implied HN points • 23 Nov 25
🌞 Climate & Environment Global Warming
  1. The cause of global warming doesn't matter as much as what we can do about it. Whether it's humans causing it or not, we still need to think about ways to prevent or adapt to climate change.
  2. There's a lot of uncertainty about the future effects of climate change. Many studies make assumptions that might not hold true over time, so we need to be careful about how we plan for the future.
  3. We might not need to act immediately on climate issues. Waiting can provide us with better information, which can help us make smarter decisions later on.

"To avoid the worst impacts of climate change, scientists say…"

The Liberal Patriot • 1316 implied HN points • 07 Jan 24
🌞 Climate & Environment Global Warming
  1. Climate discussions often mention limiting global warming to avoid the worst impacts, but there's no scientific consensus on specific limits.
  2. Focusing on the 1.5°C threshold as crucial is arbitrary, without solid scientific basis.
  3. Considering the costs of limiting warming is essential as it involves trade-offs and impacts on human well-being.

Revisiting the hot model problem

The Climate Brink • 845 implied HN points • 31 Jan 24
🌞 Climate & Environment Global Warming
  1. Recent developments and data do not support the idea that the climate is more sensitive to emissions than previously thought.
  2. Certain climate models have high sensitivity to CO2, but community reviews have suggested narrowing down the range of climate sensitivity.
  3. The exact climate sensitivity estimates can vary across studies, but regardless, the priority remains the urgent need to decarbonize our society.

The Arctic sea ice shell game

The Climate Brink • 786 implied HN points • 29 Jan 24
🌞 Climate & Environment Global Warming
  1. Winter Arctic sea ice extent remains relatively stable in recent decades.
  2. Summer Arctic sea ice has been experiencing significant declines since the early 1980s.
  3. Future projections suggest that summer sea ice in the Arctic may regularly disappear by the mid-to-late century unless emissions decline.

Sounding the Climate Change Alarm: Lessons from Carl Sagan

The Climate Historian • 19 implied HN points • 29 Aug 24
🌞 Climate & Environment Global Warming
  1. Carl Sagan connected the extreme climate of Venus to warnings about Earth's future. He showed us that understanding other planets can help us prevent our world from facing similar climate issues.
  2. Sagan proposed four key actions to tackle climate change: using fossil fuels more efficiently, developing alternative energy, reforestation, and helping the world's poorest. These ideas are still very important today.
  3. Despite Sagan's warnings and advancements in some areas, we are facing more climate challenges now. It's crucial that we change our thinking and take long-term actions for the planet's future.

The Big Heat

Diane Francis • 1019 implied HN points • 03 Aug 23
🌞 Climate & Environment Global Warming
  1. Recent extreme heat and smoke in places like New York can be partly blamed on a huge volcanic eruption in Tonga. It's important to know that natural events, like volcanoes, can impact the Earth's temperature just as much as human activities.
  2. Despite alarming headlines about wildfires and their link to climate change, the actual area burned by wildfires has been decreasing over the years. Most wildfires are caused by human actions, not climate change, and better land management could help more than strict climate policies.
  3. Global warming is a significant issue, but much of it is influenced by natural events. While we need to address our consumption and behavior, some environmental changes are beyond our control and have always occurred throughout history.
