We’re In A Jam Let’s face it, humanity is NOT going to back off anytime soon on it’s production of greenhouse gases, especially carbon dioxide from the combustion of fossil fuels. Just last year, for example, atmospheric CO2 emissions increased at their fastest rate for 30 years. So, how are we to respond to the […]

From Anthropocene To Eocene II? A mountainside near where I live gave way in January 2009 (as a result of torrential rains) resulting in Racehorse Creek rock slide. This landslide revealed a treasure-trove of fossils, mainly 55-million-year old fossils of plants that were alive during the Eocene. Most interestingly, perhaps, this time corresponds to to […]

By 2050, What Will Be The Greatest Human Impact on Plants? I first encountered the term “anthropocene” back in 2007 when I was writing a manuscript regarding some of our research in Yellowstone National Park (see Ref. 1 below). A more detailed view regarding the nature and implications of the anthropocene is presented on YouTube […]

It’s All About The CO2 Sell all your bicycles. Forget about buying a Prius®. Drive the biggest gas-guzzler you can find. Crank up that home and work air conditioning, especially if you get your electricity from coal-fired power plants. Yes, your houseplants – all green (photosynthetic) plants, for that matter (with, perhaps, a few exceptions) […]

In the past 250 years the amount of atmospheric CO2 has increased by over 40% (from 270 to 387 ppm), due mainly to human activities such as deforestation and the burning of fossil fuels. Carbon dioxide (CO2) emissions are rising faster than the worst-case scenario postulated by the Intergovernmental Panel on Climate Change ( IPCC […]

YES! Here’s How (And Why): Although “Global Warming” is to some people a controversial subject, the one thing that’s not controversial is that the level of atmospheric CO2 has significantly increased in the past 100 years and will likely continue to increase – at least until humans stop burning fossil fuels. OK, so atmospheric CO2 […]

No Controversy Here Despite the denials of global warming caused by increased atmospheric CO2 from the scientifically ignorant or from the oil/coal corporations (or from politicians bought or rented by these corporations), there is one thing they can not deny. The level of atmospheric CO2 on Earth has been steadily increasing for the past century […]

Articles about photosynthesis in the popular press or online often make me cringe. Why? Because sometimes they lead people to think that the oxygen (O2) produced by photosynthesis is derived from carbon dioxide (CO2). Some even further compound their mistake by stating that plants actually convert CO2 into O2 at night! Ack! This is simply […]

As previously mentioned….if most climatologists are correct, then parts of the Earth’s surface may experience increasing episodes of heat and drought as a result of global “weirding”. (see here and here and here for recent examples) Some of the effects of heat on photosynthesis were considered in part 1 of this post. But what about […]

m4s0n501 If most climatologists are correct, then parts of the Earth’s surface may experience increasing episodes of heat and drought as a result of global “weirding”. (see here for a current example) In a previous post in this blog, I briefly introduced the complex subject of how increasing atmospheric CO2 may affect plant photosynthesis. There […]
