The pros and cons of planting trees to address global warming

Skeptical Science - This is a re-post from Yale Climate Connections by Bruce Lieberman It seems like such a simple, straightforward, empowering idea: plant trees – a lot of trees – all over the world, and watch the planet’s temperature fall. Who doesn’t love a tree or two, even far more – the right tree in the right place? Along with the refreshing shade they provide on hot days, trees of course also store carbon, and they’ll suck it right out of our fragile … [Read more...]

Why not use a clever mathematical trick?

RealClimate - There is a clever mathematical trick for comparing different data sets, but it does not seem to be widely used. It is based on so-called empirical orthogonal functions (EOFs), which Edward Lorenz described in a Massachusetts Institute of Technology (MIT) scientific report from 1956. The EOFs are similar to principal component analysis (PCA). The EOFs and PCAs provide patterns of spatio-temporal covariance structure. Usually these techniques are applied to datasets with many … [Read more...]

Why are so many solar-climate papers flawed?

RealClimate - The Zharkova et al paper that incorrectly purported to link solar-climate effects to movements of the Sun around the barycenter has been retracted. This paper generated an enormous thread on @PubPeer where the authors continued to defend the indefensible and even added in new errors (such as a claim that the Earth’s seasonal cycles are due to variations in the Earth-Sun distance). Additionally, it seeded multiple nonsense newspaper articles in the UK and elsewhere (some … [Read more...]

Nelson, B.C. saves money with Canada’s first community solar garden

Guest Post – Keep Cool & Save Cash with the Right Window Treatments

Reduce Footprints - With summer just around the corner, now is a good time to start thinking about buttoning up your home for maximum efficiency! This is especially true for those in areas of the country that experience extreme heat, which results in frequent overexertion of air conditioners. Air conditioning units consume energy in the form of electricity. When a home has a significant amount of solar heat gain with uncovered windows, this puts a greater strain on the unit resulting in more … [Read more...]

Skeptical Science New Research for Week #12, 2020

Skeptical Science - Tamper with The System? Well, we already are. But there's a difference between accidentally trickling sand into a precision gearbox versus formulating a plan to alter it on the fly with improvements in mind. One action is more or less innocently unscrupulous, the other amenable to earning an easy conscience. Low & Buck offer a critical analysis of "RRI" or "Responsible Research and Innovation" in connection with climate change in their paper The practice of responsible … [Read more...]

Aggressive action to address climate change could save the world $145 trillion

Skeptical Science - This is a re-post from Yale Climate Connections A respected research group, Project Drawdown, finds that deploying solutions consistent with meeting the Paris climate targets would cost tens of trillions of dollars globally. But crucially, those outlays would also yield long-term savings many times larger than the up-front costs. The new 2020 Drawdown Review includes economic estimates of the capital costs to deploy each solution, net lifetime operation costs, and lifetime … [Read more...]

Further perspectives on pandemics and climate change

RealClimate - I have recently been asked whether the present corona pandemic will have any consequence on climate change. Gavin has already discussed the coronavirus and climate here on RealClimate, and I like to follow up on his post. Rather than emphasising analogies, I would highlight additional common denominators between the present world-wide Covid-19 pandemic and climate change. My first reaction is that the present crisis has taught us the value of knowledge and science. It is also … [Read more...]

Coronavirus and climate

RealClimate - As we collectively reel from the changes wrought by the current pandemic, people are being drawn by analogy to climate issues – but analogies can be tricky and often distort as much as they illuminate. For instance, in the Boston Globe, Jeff Jacoby’s commentary was not particularly insightful and misquoted Mike Mann pretty egregiously. Mike’s response is good: I am relieved to see policy makers treating the coronavirus threat with the urgency it … [Read more...]

Guest Post – Why Electric Radiators Are Essential For Eco-Friendly Living

Reduce Footprints - For years night storage heaters have been the most globally popular technology for heating homes around the world. This has been largely due to home and business owners taking advantage of the low running costs they offer, even though there has always been a concern over the harmful carbon release resulting from such usage. But now thanks to 21st century technology, night storage heaters no longer have any benefits that modern eco-friendly electric radiators don't. On the … [Read more...]
