Climate change no longer a puzzle
Research has shown that our Earth is currently going through an energy imbalance, columnist Ray Johnson writes.
Oceans seeing effects of rising temperatures
There is a planet-wide circulation of water in the oceans that transports heat, and greenhouse gases are contributing to rising temperatures in our planet's oceans, columnist Ray Johnson writes.
Dealing with the rising energy problem
Many energy experts, scientists and planners say that we do not have a carbon-dioxide problem so much as an energy problem, namely, wasted energy, columnist Ray Johnson writes.
Invasive insects evidence of climate change
Today, observations suggest we have the equivalent of a new canary in a cage, this one for detecting climate change: the presence of billions of dead trees in the North American West, Ray Johnson writes.
Cities set benchmark for fossil-fuel use
With a growing awareness of the impact of burning fossil fuels, cities developed an environmental program to take on some of the responsibility, columnist Ray Johnson writes.
Carbon dioxide emissions our legacy to the future
As we continue to consume carbon in its various forms, we are indeed delivering a legacy to future generations, columnist Ray Johnson writes.
Arctic Climate changing fast
Global ice melt is an indication that human-caused climate impacts are occurring faster than we expected, columnist Ray Johnson writes.
Planetary gases may have Earthly effect
Venus has a pronounced "runaway greenhouse" effect. This is the same greenhouse gas, the rising levels of which concerns climate scientists today, Ray Johnson writes.
Denmark: Unified on climate and energy plan for future
The Commission on Climate Change Policy found that Denmark can remove fossil fuels from its energy system completely, including transportation, by 2050, without the need for nuclear energy or use of carbon capture and storage, writes Raymond Johnson.
Past temperature changes have current meaning
Data show that about 56 million years ago our planet got very warm. Is this the beginning of a fairy tale? Not really, says Ray Johnson.
