Reconstructing Historical Precipitation in the Amazon Basin Since 1786

Paper Reviewed Granato-Souza, D., Stahle, D.W., Barbosa, A.C., Feng, S., Torbenson, M.C.A., de Assis Pereira, G., Schongart, J., Barbosa, J.P. and Griffin, D. 2019. Tree rings and rainfall in the equatorial Amazon. Climate Dynamics 52: 1857-1869. Introducing their work, Granato-Souza et al. (2019) note that “only eight instrumental rainfall records longer than 80 years with less than 10%

Recent CO2 rise has modified the sensitivity of tropical tree growth to rainfall and temperature

By Pieter A. Zuidema et al. Abstract Atmospheric CO2 (c a) rise changes the physiology and possibly growth of tropical trees, but these effects are likely modified by climate. Such c a × climate interactions importantly drive CO2 fertilization effects of tropical forests predicted by global vegetation models, but have not been tested empirically. Here we use tree‐ring analyses to quantify how c a rise

The Global Economy’s Fuel Gauge

By Mark P. Mills China is about one month ahead of the United States in exiting the Covid-19 shutdown. That country’s rush-hour traffic jams now equal or exceeded pre-lockdown levels, even in Wuhan. This quick reversal happened despite claims that telecommuting would “change everything,” especially old-fashioned commuting and, thus, oil demand. At a global level, the

Another Crack in the Climate Censorship Wall

Ecologist and CO2 Coalition Chair Patrick Moore Debates Ocean “Acidification” and “Climate Regulation” in the Inference Science Magazine. In ‘Reading Seawater,” a review essay in the December 2019 issue of the science journal Inference, Lawrence University geosciences professor Marcia Bjornerud wrote that changes in ocean chemistry from carbon dioxide emissions damage shell health and may

Early-stage evaluation of emerging CO2 utilization technologies at low technology readiness levels

By Kosan Roh et al. Abstract Most CO2 utilization technologies are at low technology readiness levels (TRLs). Given the large number of potential technologies, screening to identify the most promising ones should be conducted before allocating large R&D investment. As these technologies exhibit different levels of technical maturity, a systematic, TRL-dependent evaluation procedure is needed

German cabinet agrees CO2 price of €25 from January 2021

By Florence Schulz Germany’s cabinet agreed on Wednesday (20 May) on changes to the climate package launched last September, and it is now certain that from January 2021, a price of €25 per tonne of CO2 will apply to the heat and transport sectors in Germany. EURACTIV Germany reports. Originally, the German government’s proposal had

The relationship between economic growth and carbon emissions in G-7 countries: evidence from time-varying parameters with a long history

By Mehmet Akif Destek,Muhammad Shahbaz,Ilyas Okumus,Shawkat Hammoudeh andAvik Sinha Abstract This paper re-investigates the time-varying impacts of economic growth on carbon emissions in the G-7 countries over a long history. In doing so, the historical data spanning the period from the 1800s to 2010 (as constructed) for each country is examined using the time-varying cointegration
