Modeling ecological processes at global scales is complicated by the fact that available underlying spatial and temporal data often incorporate enormous uncertainty. For example, the WorldClim data set (which has been cited over 2000 times) offers 1-kilometer resolution globally whether the pixel …
studies and investigations pertaining to climate science in the most general sense
Climate scientists predict that climate change will lead to increased variability in precipitation over much of South America. Research by Carlton et al (2013) on residents of northwestern rural Ecuador who rely on streams and rivers for their drinking water shows how those changes might impact water quality and associated rates of diarrhea, a water-related disease which leads to approximately 1 million deaths of young children worldwide each year. The study further highlighted curious dynamics involving precipitation and water-borne disease.
A changing climate effects the availability of water, agriculture, and virtually everyone on the planet. To predict changes in vegetation cover and adapt water usage appropriately it’s necessary to constrain changes in evaporative flux. Measuring evaporation is more challenging than other components of the hydrologic
This workshop was motivated by the appreciation that our knowledge of the human role in the Arctic system over millennia can be refined and greatly improved through better integration of high-latitude archaeology, ice core and other re-constructions of climate parameters, and studies of the contemporary Arctic environment. The two-day workshop brought together researchers working across a range of disciplines in order to explore the complex relationship between the dynamic Arctic environment and long-term human cultural responses.
In a simple but important analysis, Mora and colleagues analyzed climate projections to identify when future warming will exceed the climate envelope of the past 150 years. They used multiple models (39) and seven climate variables (such as near-surface temperature …
“Polluters talk, we walk” was the chant two weeks ago, as thousands of climate change activists walked out of the 19thUnited Nations Council of Parties (COP 19) conference a day before negotiations were scheduled to end. A spokesman for Oxfam blamed negotiators for insufficient outcomes to limit global temperature rise to 2 degrees Celsius as outlined by the United Nations Intergovernmental Panel on Climate Change.

Densely populated, and with 80% of its area located on a floodplain within 8 meters of sea-level1, Bangladesh is one of the world’s most flood-prone nations. As such it’s an appropriate setting for a series of two United Nations University Resilience Academies that convene experts in research, policy and practical applications to help developing nations deal with the effects of climate change.
Clouds, air pollutants, and the underlying landscapes all impact Earth’s energy budget in complex and competing ways. Atmospheric scientists from Yale and Tokyo’s Todai University gathered at a YCEI sponsored forum in September to share how they use climate models to study how humans affect this nuanced system—and how we can possibly counteract global warming by manipulating cloud formation.
The Intertropical Convergence Zone (ITCZ) — responsible for most of the precipitation on Earth — is defined by a pronounced maximum rainfall occurring 5◦ north of the equator over most ocean basins. The existence of an ITCZ directly derives from large…
