What Is Science and What Is Technology?
What is Science? What is Technology? These are not easy questions. People don't often see the difference between them. But they are different though the two are connected. Science studies the physical world. Trying to answer questions about this world of ours scientists ask "what" and "why" questions. "What" questions are usually answered in a rather simple way. For example we have a question: "What kind of animals live in that pond?" The answer to the question is: "Frogs, fish and reptiles." "Why" questions are much more difficult, they ask for explanation.
Technology is the use of science for practical purposes especially in industry. Technology is also methods and machines that are used in doing things in a science or profession. Technology often asks "how" questions and answers them. Some technologies cannot function without science, but there are many modern technologies that developed from old technologies without any help of science. It often happened in history that people made things and after that science tried to explain them. For example, first guns appeared and then ballistics as a science did.
During certain periods in history innovations in technology have grown so fast that they resulted in industrial revolutions.

Do you belive in climate change?

This may seem like an odd question for a climete scientist to ask, but it is one I am constantly asked now. The typical discucsion starts: "I know that the climate is changing, but hasn't it always changeed through natural cycles?" Then they will often give an example, such as the medievel warm period to prove their point.
Those asking the question include a wide range of people I meet in the pub, friends, politicians and increasingly even some of those active in sustainable development and the renewable energy businesses. What I find interesting is that I have known many of these people for a long time and they never asked me this before.
Recent studies show that public acceptance of the scientific eviddence for man-made climate change has decreased. However, the change is not that great. The differennce I find in talking to people is that they feel better able to express their doubts.
This is very hard for scientists to understand. The scientific evidence that humanity is haveing an effect on the climate is overwhelming and increasing every year. Yet public percaption of this is confused. People modify their beliefs about uncomfortable truth, they may have become bored of constantly hearing about climate change; or external factors such as the financial crisis may have played a role.
Around three years ago I raysed the issue of the way that science can be misused. In some cases scare stories in the media were over-hyping climate change and I think we are paying the price for this now with a reaction the other way. I was concerned then that science is not always presented objectively by the media. What I don't think any of us appreciated at the time was the depth of disconnect between the scientific process and the public.
Which brings me on to the question, should you believe in climate change? The first point to make is that it's not something you should believe or not believe in – this is a matter of science and therefore of evidence – and there's lots of it out there. On an issue this important, I think people should look at that evidence and make their own mind up. We are often very influnced by our own personal experience. After a couple of cold winters in the UK, the common question was "has climate change stoped?" despite that fact that many other regions of the world were experiencing record warm temperatueres. And 2010 was one of the warmest years on record. For real evidence of climate change, we have to look at the biger picture.
You can see reseerch by the Met Office that shows the evidence of man-made warming is even stronger than it was when the last report was published. A whole range of different datesets and independent analises show the world is warming. There is a broad consensas that over the last half century warming has been rapid, and man-made greenhouse gas emissions are very likely to be the cause.
Ultimately, as the planet continues to warm the issue of whether you believe in climate change will become more and more irrelevant. We will all experience the impacts of climate change in some way, so the evidence will be there in playn sight.
The more appropriate questions for today are how will our climate change and how can we prepare for those changes? That's why it's important that climate scientists continue their work, and continue shareing their evidence and research so people can stay up to date – and make up their own minds.
