Most scientists have, however, settled to use the term climate change to refer primarily to observed and predicted changes mainly as a result of human activities [ 53767778 ], though others suggest that climate changes are a result of natural cycles [ 3 ]. Climate variability global warming 101 national geographic the other hand has been defined as variations in the mean state and other statistics such as standard deviations and the occurrence of extremes of the climate on all temporal and spatial scales beyond that of individual article source events warning to natural internal processes within the climate system i.
Such changing climatic patterns have been global warming 101 national geographic with various extreme events or phenomena such as droughts and floods [ 1342545790 ]. This notion is also buttressed in a review of observed — and possible future — climatic conditions across Africa by Hulme et global warming 101 national geographic.
Impacts of anthropogenic processes on the global carbon cycle and the resultant greenhouse effect have been acknowledged as directly linked to global and regional climatic systems perturbations with the same devastating effects on numerous vulnerable communities around the world, for example [ 2975889192 ]. The IPCC further emphasised a dire need for drastic global action [ 93 ] to achieve this in light of a narrow window period of up to to stem catastrophic climate change projected by scientists such as Miller, Croft [ 94 ].
However, such global climate change governance efforts have not been without major drawbacks as highlighted by the withdrawal of the United States of America USA in from the Paris Accord citing unfairness of the agreement and possible threats to US economic interests [ 959697 ]. Furthermore, it is worth mentioning that the recent SARS-CoV-2 COVID pandemic has also brought in a new dimension into the existing global climate change research and governance discourse [ 9899] though this is not within of the scope of this review.
Climate vulnerability describes the degree to which a system is susceptible to, and unable to cope with, adverse effects of climate change and variability and extremes [ 75 ]. Global warming 101 national geographic is a function of climate sensitivity and adaptive capacity of communities and natural systems [ ]. Climate change increases frequency and intensity geograpnic extreme events such as storms, droughts and wildfires which impact on the global food supply, displace communities, and disrupt livelihoods thus increasing the risk of conflict, hunger and poverty [ ]. Numerous climate impacts studies covering vulnerabilities and adaptation such as [ 15, ] have been done and the general consensus is that climate change and variability present geogrraphic vulnerability challenges as earlier alluded to in most regions globally. Within the semi-arid regions in Southern Africa, challenges such as crop failure, land degradation and deforestation are prominent considering their ecosystems and agriculture depend on rainfall for their primary production.

In this regard, researchers such as Berrang-Ford et al. Among other conclusions drawn, all these have revealed a need for pragmatic policy development buttressed by sound scientific evidence to guide mitigation and adaptation strategies especially in developing countries such as Zimbabwe [ 34 ]. Climatic change and variability studies in Zimbabwe Climate in Zimbabwe is highly variable [ ] and thus the country with its global warming 101 national geographic coping capacity is considered highly vulnerable to climate change and watming impacts like most developing countries in Africa, e.
One of the six core objectives of the NCP was to strengthen climate research and modelling and promote relevant home-grown solutions to address the challenges of climate change [ 71 ]. A synergy in all these developments, i. The rest are contributions come from researchers affiliated to research institutions outside of Zimbabwe.

These results reveal a dearth of scientific knowledge primarily within the themes of climate modelling, climate governance and general climatic trends, respectively, in Zimbabwe. Results show a publication rate of 3. Climate impact studies are predominant.]
