Celebrating Science and Hispanic Heritage Month: A Conversation with Hector Arce

, Deputy director, Center for Science & Democracy

Diversity strengthens science. It’s more than just a matter of fairness and equity—diverse groups of people create better science. Yet it should come as no surprise that people of color continue to be underrepresented in science and engineering. Some people and organizations are doing their best to change that. Read more >

Cleveland Can Beat the Heat by Planting Trees—But Don’t Forget Environmental Justice

, Climate Scientist

Climate change presents many threats to cities, compromising their ability to protect public health, or deliver critical services like sewage disposal or adequate protection against storm surges and flooding. Many cities are acutely aware of these threats, and are developing climate adaptation plans with strategies to mitigate, and adapt to, climate change impacts. Read more >

Article (doi:10.1175/WCAS-D-15-0026.1) Declet-Barreto, J.; Knowlton, K.; Jenerette, G. D. & Buyantuev, A. Effects of urban vegetation on mitigating exposure of vulnerable populations to excessive heat in Cleveland, Ohio Weather, Climate, and Society, 0, 0, null Abstract: AbstractHot weather is a threat to human health, especially in cities, where Urban Heat Islands (UHIs) are elevating temperatures already on the rise from global climate change. Increased vegetation can help reduce temperatures and exposure to heat hazards. We conduct an ensemble of Geographically Weighted Regressions (GWR) on Land Surface Temperature (LST) for May-October to estimate potential LST reductions from increased vegetation and assess the effect of temperature reductions among vulnerable populations in Cleveland, Ohio, USA. We apply possible tree canopy increases to our results, finding that LST reductions can range from 6.4 to 0.5 °C for May-October, and are strongest from May-July. Potential LST reductions vary spatially according to possible canopy increases, are highest in suburban fringe neighborhoods and lower in downtown areas. Among populations at high heat-related health risks, the percentage of the population 65 years of age or older in Cleveland is negatively associated with LST, while percentages of Hispanics and those with low educational achievement are most positively associated with higher LST. Percent Hispanic also has the lowest potential temperature reductions from increased vegetation. Neighborhoods with the highest potential temperature reductions had the highest percentages of Whites. Three sub-populations associated with high heat health risks are negatively correlated (African-Americans, the elderly) or not correlated (persons living in poverty) with LST, and the relationships to LST reduction potential for all three are not statistically significant. Our estimates of the effect of vegetation increases on LST can be used to target specific neighborhoods for UHI mitigation under possible and achievable, policy-prescribed tree canopy scenarios in Cleveland.
