An international team of 32 authors from 24 institutions in eight countries has just published a study titled “Greening of the Earth and its Drivers” in the journal Nature Climate Change showing significant greening of a quarter to one-half of the Earth’s vegetated lands using data from the NASA-MODIS and NOAA-AVHRR satellite sensors of the past 33 years. The greening represents an increase in leaves on plants and trees. Green leaves produce sugars using energy in the sunlight to mix carbon dioxide (CO2) drawn in from the air with water and nutrients pumped in from the ground. These sugars are the source of food, fiber and fuel for life on Earth. More sugars are produced when there is more CO2 in the air, and this is called CO2 fertilization.
The beneficial aspect of CO2 fertilization in promoting plant growth has been used by contrarians, notably Lord Ridley (hereditary peer in the UK House of Lords) and Mr. Rupert Murdoch (owner of several news outlets), to argue against cuts in carbon emissions to mitigate climate change, similar to those agreed at the 21st Conference of Parties (COP) meeting in Paris last year under the UN Framework on Climate Change (UNFCCC). “The fallacy of the contrarian argument is two-fold. First, the many negative aspects of climate change.

In a little over seventy eight days the United Kingdom will vote on whether to stay or leave the European Union, it will be a close vote and people will decide having been subjected to a campaign based on fear. Fear of what will happen to the UK and its peoples if we vote ‘Leave’, because that is what works. However, that cuts both ways.
Glaciers are key icons of climate change and global environmental change. However, the relationships among gender, science, and glaciers – particularly related to epistemological questions about the production of glaciological knowledge – remain understudied. This paper thus proposes a feminist glaciology framework with four key components: 1) knowledge producers; (2) gendered science and knowledge; (3) systems of scientific domination; and (4) alternative representations of glaciers. Merging feminist postcolonial science studies and feminist political ecology, the feminist glaciology framework generates robust analysis of gender, power, and epistemologies in dynamic social-ecological systems, thereby leading to more just and equitable science and human-ice interactions.
