Neolithic tools provide clues for managing climate change

Archaeological tools from an ancient site outside Jerusalem provide insights into land use patterns and sustainable resource management during extreme climate change. The study, published in PLOS ONE, suggests that Neolithic humans adapted to changing environments by clearing forests for fields and grazing lands.

Shrinking leaves point to climate change

Researchers analyzed leaves from herbarium specimens and found a 2mm decrease in leaf width over 127 years. This response highlights the impact of climate change on Australian plant species, with Narrow-leaf Hopbush exhibiting narrower leaves in warmer temperatures.

Big uncertainties in the global water budget

Researchers found significant differences between global models and measurement data sets, with uncertainties increasing due to a shrinking global network of measurement stations. This study emphasizes the need for better understanding of evaporation, clouds, and precipitation interactions on regional levels.

Is California preparing for climate change?

A majority of California's coastal planners acknowledge the need to prepare for climate change impacts like rising sea levels and increased floods. Despite challenges such as limited funding and staff resources, many professionals are actively planning and trying to understand their climate change risks.

Gourmet butterflies speed north

A new study found that warmer summers have allowed the Brown Argus butterfly to shift its diet to wild Geranium plants, enabling it to expand its range in Britain at a rapid rate. Over 20 years, the butterfly has spread northwards by 79km, becoming common in southern England.

Research: 'Modern Portfolio Theory' optimizes conservation practices

A study from the University of Illinois demonstrates that adapting Modern Portfolio Theory for conservation purposes can help reduce outcome variation under climate change. By diversifying strategically across space, conservationists can achieve a 15% higher value of the conservation-objective-per-dollar-spent while reducing uncertainty.

Harp seals on thin ice after 32 years of warming

A new study reveals that harp seal populations are experiencing sharply higher death rates among pup mortality, with entire year-classes disappearing from the population in low ice years. The study suggests that seasonal sea ice cover has declined by as much as 6% per decade since 1979, leaving the population on thin ice.

Walnut trees may not be able to withstand climate change

Researchers at Purdue University found that walnut trees are highly sensitive to certain climates and may struggle to survive in a changing environment. The trees' defense mechanisms against cold and extreme weather events could be compromised by climate change, leading to potential declines in the species.

New insight into climate change in the Pacific

The report presents the most comprehensive scientific analysis of climate change in the Pacific region, indicating warmer temperatures, ocean acidification, and increased extreme weather events. Future projections suggest decreased droughts and tropical cyclone frequencies, but increased extreme rainfall and sea-level rise.

Climate adaptation of rice

Researchers discovered that colonizing rice plants with fungal spores from naturally salt-tolerant plants enhances their ability to withstand cold, salt, and drought. This emerging strategy, called symbiogenics, could help mitigate climate change impacts on global food security.

Gene flow may help plants adapt to climate change

A study on gene flow in Sierra Nevada cutleaved monkeyflower found that mixing genes from warmer and cooler elevations improves the plant's ability to thrive in a changing environment. This technique can be used to augment genetic resources for imperiled populations, enabling them to better adapt to climate change.
