Climate Change

formerly “Climate Science” this has been updated in recognition of the fact that ALL of our articles, events, etc. involve climate sciience.  ”Climate change” is intended to suggest changing elements of the climate: e.g., shifts in global oceanic and atmospheric circulation and ensuing changes to temperature, precipitation, groundwater levels, saltwater intrusion.

Global Change Biology: The influence of global warming

­­­­­Paleontologists report that our planet has experienced five mass extinctions. By most accounts we are living through one more (the subject of last year’s Pulitzer-prize winning The Sixth Extinction, by Elizabeth Kolbert).  With species estimated to be disappearing perhaps 1000 times faster than prior to the arrival of man, the Yale Climate and Energy Institute sponsors talks next week by scientists seeking to understand how global forces like habitat fragmentation and climate change interact to remake life on Earth.

New study finds more trees than suspected on Earth, but disappearing at a frightening rate.

A team of scientists has determined that there are trillions of trees on planet Earth – not billions, as was previously thought. The new estimate of 3,040,000,000,000 trees, which is nearly eight times higher than earlier estimates, was made in a multidisciplinary study combining analysis of satellite imagery with counts made by thousands of volunteers working in forests around the world. The team was led by YCEI post-doctoral fellow Thomas Crowther while working during the last two years at Yale School of Forestry & Environmental Studies.

CO2 and Plant Productivity: Mostly a single-edged sword

A new metric called “suitable plant growing days” helps address an argument often made by climate skeptics: since carbon dioxide promotes plant growth – especially at middle and high latitudes – anthropogenic carbon dioxide emissions will increase agricultural yields and carbon sequestration across the world’s forests.  The relationship is not so simple, however. Other factors influenced by climate change (e.g., temperature, water availability, solar radiation) strongly affect plant growth and survival as well. The interactions…

Climate Change as Culprit in Bumblebee Decline

The alarming rate of decline of bumblebees—key pollinators of crops and wildflowers across the world and an essential part of a healthy environment— has been at the forefront of scientific news for the past several years. To date, most of the bee die-off has been attributed to changes in agricultural practices and the use of bee-killing pesticides such as neonicotinoids. Recent study, however, adds another dimension to the decline of bumblebees. Kerr et al. (2015) used over 100 years of observations across European…

Need for Air Conditioning May Contribute to Climate Change

As climate change continues and temperatures rise, people around the world will have to adapt to new climate realities. Globally, household incomes are expected to continue rising over the coming decades, so as average temperatures increase most people will likely respond by increasing their use of air conditioning, thus potentially increasing electricity consumption and greenhouse gas emissions.

A recent study of income growth, increasing…
