A new study reveals how climate change has altered growing conditions for the world's five major crops over the past half century and is reshaping agriculture. The impacts corroborate climate models used to predict impacts, with a couple of important exceptions according to the researchers.

Researchers have released their 2024 U.S. sea level 'report cards,' providing updated analyses of sea level trends and projections for 36 coastal communities. Encompassing 55 years of historical data in a new, interactive dashboard, the report cards aid planning and adaptation efforts by forecasting rates of sea level rise to 2050.

Atmospheric and climate scientists show that biological particles may induce rain events that could contribute to flooding and snowstorms, owing to their ability to precipitate ice formation in clouds. They call for an update of meteorological and climate models.

The disappearance of sea ice in polar regions due to global warming not only increases the amount of light entering the ocean, but also changes its color. These changes have far-reaching consequences for photosynthetic organisms such as ice algae and phytoplankton.

Urgent action must be taken to reduce the ever-rising number of people killed by extreme temperatures in India, say the authors of a new 19-year study which found that 20,000 people died from heatstroke in the last two decades. Cold exposure claimed another 15,000 lives.

Trees, parks, wetlands and green roofs can no longer be seen as a 'nice-to-have' aesthetic enhancement but a vital component for creating climate-resilient, healthier and more equitable cities, according to an international paper.

The global energy system may be faced with an inescapable trade-off between urgently addressing climate change versus avoiding an energy shortfall, according to a new energy scenario tool.

New research has revealed that expected, extreme changes in India's summer monsoon could drastically hamper the Bay of Bengal's ability to support a crucial element of the region's food supply: marine life. The scientists examined how the monsoon, which brings heavy rains to the Indian subcontinent, has influenced the Bay of Bengal's marine productivity over the past 22,000 years.

Even under today's climatic conditions, the long-extinct straight-tusked elephant could still live in Europe. This is the conclusion of a recent study. For this finding, the research group combined fossil finds with reconstructions of past climates.

Climate change is increasing the risk of wildfires in many regions of the world. This is due partly to specific weather conditions -- known as fire weather -- that facilitate the spread of wildfires. Researchers have found that fire weather seasons are increasingly overlapping between eastern Australia and western North America. The research team examined the causes of this shift and its implications for cross-border cooperation between fire services in Canada, the US, and Australia.

Many of the fish we eat play a key role in maintaining the seabed -- and therefore our climate, new research shows.

A new study has found worrying signs that climate change may be undermining the capacity of Arctic fjords to serve as effective carbon sinks. The findings suggest that the capacity of polar oceans to remove carbon from the atmosphere may be reduced as the world continues to heat up.

In examining how different countries have rolled out climate change mitigation strategies, research has found reasons to be optimistic about preserving our environment while promoting prosperity and well-being.

A new study finds that presenting the same continuous climate data, such as incremental changes in temperature, in binary form -- such as whether a lake did or did not freeze in the winter -- significantly increases people's ability to see the impact of climate change.

Multiple climate 'tipping points' are likely to be triggered if global policies stay on their current course, new research shows.

Over the past two decades, satellite-based planetary observations have recorded rapid mass loss of Patagonian glaciers, contributing approximately 0.07 mm per year to global sea-level rise. A study links this mass loss to a poleward shift of subtropical high-pressure systems. This large-scale atmospheric circulation change brings more warm air to Patagonia, thereby accelerating glacier melt.

A new study lays out a scientific framework for holding individual fossil fuel companies liable for the costs of climate change by tracing specific damages back to their emissions. The researchers use the tool to provide the first causal estimate of economic losses due to extreme heat driven by emissions. They report that carbon dioxide and methane output from just 111 companies cost the world economy $28 trillion from 1991 to 2020, with the five top-emitting firms linked to $9 trillion of those losses.

Scientists believe that the motion of Earth's continents through plate tectonics has been largely steady over millions of years. New research, however, suggests this drift can speed up or slow down over relatively short time periods.

Some species that breed over large geographic areas can still be adapted to a fairly narrow range of climates, making them more vulnerable to climate change than previously thought. Also, species with larger brains (relative to their body size) tend to be adapted to narrower climate niches, which suggests they too could also be more vulnerable than once thought.

A new study has shed unprecedented light on the highly variable and climate-sensitive routes that substances from Siberian rivers use to travel across the Arctic Ocean. The findings raise fresh concerns about the increasing spread of pollutants and the potential consequences for fragile polar ecosystems as climate change accelerates.
