Nili Gilbert has always enjoyed solving difficult problems. As a young girl, she spent hours poring over the mind-bending book The Lady or the Tiger? And other logic puzzles. Years later, while working as a quantitative investor, he was modeling human behavior which turned out to be a particularly difficult puzzle. Today, as Vice President […]
As Maryland senators wrestle with a massive overarching bill to zero the state’s carbon footprint, members of the House of Delegates are tackling these climate change issues in four separate bills. One such bill, requiring the state to gradually convert to an all-electric fleet, has already passed the House. Two others, calling for new construction […]
Women planting cassava on newly prepared land in Nigeria, July 12, 2017. [AFP, Courtesy] A walk through Nairobi’s Karura Forest on a cool morning is nostalgic. One cannot help but marvel at various native trees and shrubs. A shrub, we learned, is known as mutatis in Gikuyu language (umbrella tree). Its leaves and branches are […]
Let’s take a look at some chemistry first. Don’t worry, please stick with it and there are no tests. Hydrogen is the first element of the periodic table and its atomic number is 1. It is a clear, colorless, odorless and highly combustible gas. Also of note, hydrogen is the most abundant chemical substance in […]
Compelling academic articles The Global Research Alliance for Sustainable Finance and Investment is a collaboration of universities committed to producing high-quality, interdisciplinary research and teaching programs in sustainable finance and investment. In this series, we highlight compelling papers presented at the last GRASFI conference, with commentary from a BNP Paribas Asset Management ‘practitioner’. As the […]
May 18, 2021 Led by Dr. Wei and Dr. Qiao of the First Institute of Oceanography of the Ministry of Natural Resources, a new study offers an evaluation of the performance of recently released CMIP6 models in simulating the deceleration of global warming seen in the early 2000s. Warming rate during the rapid warming period […]
This graph illustrates the buoyancy effect of vapor, in which cold, moist air rises because it is lighter than dry air. Credit: Da Yang/UC Davis The lightness of water vapor dampens global warming in the tropics. Conventional knowledge holds that warm air rises while cold air sinks. But a study from the University of California, […]
Climate skeptics have long questioned the accuracy of computer models that predict global warming, but most early climate models turn out to be spot-on, according to a flashback from University of California climatologists at Berkeley, Massachusetts Institute of Technology and NASA. Of 17 climate models published between the early 1970s and late 2000s, 14 were […]
In climate science, models are essential tools in trying to understand an uncertain future. But attempts to predict the future are easy targets, and climate change skeptics have long sought to poke holes in past climate change predictions to undermine the credibility of today’s dire warnings. Now a full review of climate models dating back […]
This color-coded map shows global surface temperature anomalies. Temperatures above normal are shown in red and temperatures below normal are shown in blue. (NASA Goddard Space Flight Center) Of the 17 climate change models examined, 14 were accurate enough to predict the effects of global warming. The researchers fed the actual emission levels into the […]
UNIVERSITY PARK, Pennsylvania — Equilibrium climate sensitivity — the sensitivity of Earth’s climate to changes in atmospheric carbon dioxide — may be underestimated in individual climate models, according to a team of climatologists. “Probabilistic estimates of climate system properties often rely on comparing the model simulation with observed temperature records and an estimate of internal […]
A new reconstruction of global mean surface temperature trends over the past 2,000 years has identified the major causes of decade-scale climate change. The analysis suggests that the Earth’s current rate of warming, caused by human emissions of greenhouse gases, is greater than any previously observed rate of warming. The researchers also found that airborne […]
Source: Geophysical Research Letters One of the most difficult questions regarding climate change is how the warming of the Earth’s atmosphere will affect water availability around the world. Climate models present a range of possible scenarios, some more extreme than others– which can complicate planning for cities, states and countries. Now, however, in a new […]
Professor Stephen Belcher is Chief Scientist at UK Met Office; Doctor Olivier Boucher is at the head of Pierre Simon Laplace Institute (IPSL) Climate Modeling Center; and Professor Rowan Sutton is director of climate research at UK National Center for Atmospheric Sciences (NCAS), Reading University. The first results of a new generation of global climate […]
Research by a UMD professor that separates the Earth’s natural climate variability from external factors indicates that these external factors – in particular greenhouse gas-induced climate change – are the probable cause of global warming of the planet. The study found that natural climate variability has likely helped keep things cooler in recent years than […]
