"Our analysis suggests that US climate financing is not distributed to meet global mitigation goals at both the investment and climate solution scale. "
This is a fascinating study showing how misaligned venture capital can be when it comes to climate. Instead of chasing high-impact carbon solutions, it tends to chase fads.

We need to do a better job aligning our money with a more substantial climate impact.

Regenerative agriculture is mostly overhyped as a climate solution. But in Brazil, I saw some regenerative grazing practices produce higher beef yields, which meant more money for the rancher and less eating of the earth.

Very important.
A new Nature paper accompanying the Global Carbon Budget finds that the land and ocean sinks are 25% smaller and 7% smaller, respectively, than they would have been without the effects of climate change over 2015-24:
Emerging climate impact on carbon sinks in a consolidated carbon budget | Nature
Despite the adoption of the Paris Agreement ten years ago, fossil CO2 emissions continue to rise, pushing atmospheric CO2 levels to 423 ppm in 2024 and driving human-induced warming to 1.36°C, within years of breaching the 1.5°C limit 1,2. Accurate reporting of anthropogenic and natural CO2 sources and sinks is a prerequisite to tracking the effectiveness of climate policy and detecting carbon sink responses to climate change. Yet notable mismatches between reported emissions and sinks have so far prevented confident interpretation of their trends and drivers 1. Here, we present and integrate recent advances in observations and process understanding to address some long-standing issues in the global carbon budget estimates. We show that the magnitude of the natural land sink is substantially smaller than previously estimated, while net emissions from anthropogenic land-use change are revised upwards 1. The ocean sink is 15% larger than the land sink, consistent with new evidence from oceanic and atmospheric observations 3,4. Climate change reduces the efficiency of the sinks, particularly on land, contributing 8.3 ± 1.4 ppm to the atmospheric CO2 increase since 1960. The combined effects of climate change and deforestation turn Southeast Asian and large parts of South American tropical forests from CO2 sinks to sources. This underscores the need to halt deforestation and limit warming to prevent further loss of carbon stored on land. Improved confidence in assessments of CO2 sources and sinks is fundamental for effective climate policy.

Useful summary. I could quibble over some points but the talk highlights key issues. A big point is that deforestation to expand ag land causes 11% of global GHG emissions. So real pressure to minimise this and grow more food on existing ag land. But sensibly without increasing emissions.
For those looking to fund food system solutions, my DM's are open.
The most under-appreciated (and under-funded and under-reported) driver of climate change is our food system.

Our food system emits ~1/3 of global emissions. But it only gets 3% of climate funding and 4% of media coverage.

Let’s focus more on food.
