There are a lot of people out there with genuine questions about climate change, and a few who are paid to sow doubt about the issue. On this page we tackle some of the tough questions, and more than a few of the outright lies that are repeated far too often.
Also see the
Solutions myths FAQ and the
General Greenpeace FAQ.
Have you heard something about climate change that just doesn't sound
right? Or maybe there's a question about the issue that's been
bothering you for a while.
Send it to us.
Really, we'd love to hear from you - whether you're a school kid, a
blogger, a member of the general public or a PR flack for the fossil
fuel industry. If enough people ask a question, we'll post the answer
here.
Common myths, misconceptions and a few good questions about climate change:
Q:
Is there really solid science behind what we think we know about
climate change? I heard that some scientists still disagree.
We think Lord Robert May, President of the Royal Society (the world's
oldest scientific society) said it well in his 2004 anniversary address:
"There are, as always, questions about particular details. But those
who suggest that the marked changes in climate patterns are not
associated with human activities (as some still do) are isomorphic with
those who suggest that cigarette smoking is not the major cause of lung
cancer (as some still do)."
The reality is that there is far
more agreement than disagreement about climate change. Much of the so
called "debate" about the issue is largely thanks to sophisticated PR
work by the fossil fuel industry, and fact that journalists feel
obligated to cover "both sides of the story" – even when one side is
demonstrably wrong.

scientific consensus page.
Q: Shouldn't we be building more nuclear power plants? Aren't they greenhouse gas free?
Really, we can't understand why anyone (outside of the nuclear
industry) thinks this is a good idea. Nuclear power is the most
expensive and most dangerous means ever devised by humans to boil
water. Plus, it still has all of the same fundamental problems it
did ten, twenty and thirty years ago (risk of nuclear weapons
proliferation, the unsolved radioactive waste problem, plant safety
problems, security issues, etc. etc.). It's time to stop throwing
good money after bad.

Solutions pages for proven energy alternatives.
See
The nuclear fallacy for more on why nuclear isn't the answer to climate change.
See our
Nuclear issue section of this website for more information about nuclear power.
Q:
In fiction writer Michael Crichton's book "State of Fear" his
characters say the climate change is all made up (by terrorists), and I
heard that's what he really thinks (except for the terrorists
part). We're not literary critics so we won't
pass judgement on "State of Fear" as a work of fiction (tempting though
that might be). From the standpoint of scientific accuracy, we
will say the book is full of falsehoods and deceptive
half-truths. But since others have done such a good jobs of
debunking it, we won't bother...

However, we will note that for a guy who claims to be "troubled by the
insensible and distracting contentiousness that seems to inform so much
of current political debate" , he sure goes out of his way to trump it
up.
Q: I know for a fact
that plants use carbon dioxide to grow. Won't more carbon dioxide
just make plants grow faster – so we'll have more forests, more food
and no climate change because the plants will absorb the extra carbon
dioxide? Unfortunately, no. Carbon fertilization,
as the effect is called, may help to some extent in the short term, but
is well documented to be a false hope. One problem is that there
are other factors besides carbon dioxide keeping plants from unlimited
growth. One example is soil nutrients. Another is
water.

this post on RealClimate for more info.
Q: How can a few degrees be such a big deal? Where I live the temperature changes more than that in a day.
Small changes in the global average temperature can have big
effects. For example, the last ice age was only about 5° Celsius
(9°F) cooler than today. Since the late 1800's our planet has
warmed about 0.6°Celcius (1.1°F), and even with that small amount of
heating we're seeing serious impacts.
For more information see our
Science page.
Q: Stopping climate change isn't practical. Why can't we just adapt to it?
When your house is on fire, the first thing you do is put the fire out
– not try and get used to the heat. The truth is that we will
need to do a lot of adapting just to cope with the more than 1°C
(1.8°F) that is now basically inevitable (thanks to past and current
emissions). But we will also need to hold the global rise in
temperature to under 2°C (3.6°F). If it goes any higher, we are
at a greater risk of catastrophic impacts and run away feedback
effects.
Fortunately, there are proven technologies we
can use to get the energy we need without more climate change.
See our Solutions section for more detail.
However, in respect
to both adaptation and implementing solutions, the richer nations must
take the lead and provide assistance. Indeed, they are bound to do so
by treaty obligation, having signed the UN Framework Convention on
Climate Change. Many poorer countries simply don't have the resources,
money or expertise to go it on their own. Besides, it's largely
the richer nations that have caused the problem in the first place, by
centuries of fossil fuel burning and deforestation.
