Re: 2010, another year of extreme coral bleaching It's called science, you go out and measure and observe things and then develope theories to explain the data. In the case of atmospheric CO2 there are different isotope ratios that identify its' source, and human activity is resulting in the...

Re: 2010, another year of extreme coral bleaching Is it any wonder you have a Klingon as a avatar, this is more science fiction than science fact. I didn't waste my time reading all this but there's a few points I'll respond to. First off beginning a switch right now to a less carbon...

Re: 2010, another year of extreme coral bleaching Hansen is doing science not spin, which is why contrarians like you find him so threatening.

Yup, it's the greatest scam ever and the best funded. The fossil fuel sector has spent over a billion dollars in the last dozen years funding think tanks and PR firms to attack the science while lobbying politicians on a massive scale, there's more than four lobbyists for each US congressman...

Yes, but for less and less species every day. Research shows that habitats are migrating polewards at about 35 kilometres a decade while the biotas(flora and fauna) are only able to migrate at about 8 km/decade. With the warming already inevitable we're looking at a loss of about 20% of...

We overwhelmed the natural climate forcings years ago, the change going on now is at a rate only seen rarely in the geological record, namely the mass extinction events.

With a current global energy imbalance of about +0.5w/m2 and C02 concentration increasing by over 2ppm a year I think you can write off most of the coral reefs in the world by the mid point of this century if not sooner. Change is happening so fast that corals and the communities associated with...

Then go ahead and tell your kids their future is going to be a lot harsher than ours was, and that their grandkids and beyond may have no future. Do I need to point out how ridiculous it is to focus on the short-term disruption of switching to a low GHG emitting energy model while ignoring the...

So everything is OK? The models from people like James Hansen that predicted the changes 30 years ago that we're already seeing today indicate very catastrophic consequences if we continue on the course we're on. Keep in mind that it takes decades and even centuries for the full effects of...

A little pain now to avoid a lot later, that's the choice, and it's a hell of a lot more than an off chance. We're altering the chemical composition of the Earth's atmosphere at unprecedented rates and expecting what, a mild climatic response? If you look at the Paleocene-Eocene Thermal...

I've been doing a great deal of reading in the last six months on Global Warming, climate change and the extensive campaign by industry to dely and block change as long as possible. Some things to keep in mind: -Companies like ExxonMobil, Southern Company and associations like Western Fuels...

The sensitive glasses, warm smiles, sweaters and slacks, the 'come hither Canadians' glances leering out at us from magazine and newspaper photos and TV screens. Is anyone else getting totally creeped out by the 'new' Steven Harper the conservatives are trying to peddle on us?

Show me where the IPCC is recommending genocide as a remedy to climate change. The basic thermodynamics on this issue are clear, you increase the energy carrying capacity of the atmosphere and the global temperature average goes up. The predictions made several decades ago are coming to...

I've got a limited amount of time. Little of what gets said here gets listened to anyway.

The green agenda is about sustainability, if we don't do anything the economy is going to go bust anyway as the environment collapses. I'm not sure who you're refering to, but I don't recall many credible sources claiming we need to eliminate large numbers of the population. On the contrary...

Who talking about eliminating anybody? There's a huge amount of waste in how we use energy and resources, the cutbacks need to come in our habits, not a segment of population. There's no doubt in my mind that before too many more years have gone by what we consider normal now will be...

Some people will believe anything... Not all scientific theories are equal, a concept Isaac Asimov refered to as The Relativity of Wrong. While there is some uncertainty in the global warming scenario, there's far more uncertainty in the contention that the global climate is static or even...

They can do more, we all can. One or two persons footprint isn't the issue, it's an entire industry that prevents necessary changes that is. How about some details. The world in awash in unused energy, solar alone can more than meet our demands. Factor in the many other sources and fossil...

And yet they're still speaking truth to power, it's a lot more than most do. Proven in what court? If people were given a viable choice I'm sure they would take it. But like the dinosaurs tying up most of the the ecological niches preventing the greater success of mammals the fossil fuel...

Maybe in the fantasy world of the virtuous businesman trashing people like Gore, Suzuki and other organizations and individuals that came before them makes sense. But we live in the real world where individuals and organizations often produce and sell things they know to be toxic. Things like...
