Robert F. Kennedy Jr. likes regenerative agriculture, but what is it?
The term has no fixed definition. Its methods do often make farming more sustainable, but its claims are hard to verify.

If CO2 is 0.04% of Earth’s atmosphere, how does it cause climate change?
Common air pollutants – such as sulfur dioxide, or ozone – reach unsafe levels for humans at just a few micrograms (millionths of a gram) per cubic meter, or just a few parts per billion, far less than the percentage of CO2 in the atmosphere. Thanks to how the greenhouse effect works, a little CO2 can cause a lot of heating.

Myths about weather control and geoengineering: here’s what you should know
Humans cannot control Earth’s weather with technology at a large scale – even at smaller scales, our capabilities are extremely limited. Humans can, however, have a long-term influence on weather through climate change by emitting greenhouse gases.

Major wine regions could disappear from global warming, Europe to be hit especially hard
Wine grapes can only be grown in specific conditions – climate change is affecting which regions are suitable, and some current regions will likely be lost.

Cutting emissions today limits future climate impacts, but certain changes are ‘locked in’ due to past CO2 emissions
Sea levels will rise this century and remain elevated for thousands of years due to our past emissions. Ice sheets, glaciers, and ocean temperatures will also face irreversible changes.

Heatwave in England to bring temperatures above 32°C (89.6°F) – study finds climate change made this 100 times more likely
Study finds climate change made June 2025 heatwave in England 10 times more likely and temperatures above 32°C (89.6°F) 100 times more likely.

Glacier collapse recently buried a Swiss village – here’s what scientists say triggered the event
The Birch Glacier collapse was mainly triggered by sudden rock avalanches which accumulated on top of the glacier, adding excess weight. Climate change likely contributed by destabilizing the slope of the Kleines Nesthorn mountain peak.

Human-driven climate change largely responsible for last 50 years of worsening fire weather in Western North America, new study shows
Fire weather has been worsened by human-driven climate change in Western North America for 50 years, new study finds. Recent paper suggests that human-driven climate change contributed 81-188% to the observed increase in fire weather in that region.

Agriculture emits greenhouse gases, but less than using fossil fuels, despite recent paper’s claim
A paper used unusual accounting methods by looking only at gross emissions and omitting CO2 sinks through reforestation; climate scientists explain that this method is misleading. It is like evaluating the status of your bank account based only on your income without looking at your expenses.

Is vehicle pollution still a problem? Yes, here’s why it still harms health and climate
Individual vehicle emissions have improved through tighter regulations and better technologies, but vehicle pollution is an ongoing issue that harms human health and worsens climate change.
